Utopia

9

ALVAR KRESH STARED out the window of his home, and watched the rain come pouring down. Rain—lifegiving, welcoming rain. It was a rare thing for the city of Hades, and always a most welcome one.

But the rain and the darkness made the way impossible to see, and made the going slippery. Flash floods could wash out the road altogether. It was best to stay in one place, stay inside and home and dry in the rain. But Kresh could see another, larger, and more dangerous storm, one that had swept across the planet, Comet Grieg bearing down in its wake. In that larger storm, the storm of politics and decision and danger, Kresh had no choice but to move forward, to venture out and choose the direction that would lead to safety.

If any direction could do so. If there was any way to choose a path, or any way to know that it would lead in the direction it seemed to go.

What was to be done?

Alvar Kresh had faced many decisions in his life, made many choices that affected many people, but never had he felt the loneliness of decision more. If only Lentrall had discovered his damnable comet sooner. If only there were more time.

“What am I going to do?” he asked the rain, speaking softly enough that his voice would not carry. But there were no answers, no guidance there. He turned around and looked around his living room. Fredda and Donald were there, watching him, waiting for him to speak to them.

It was a big, comfortable, informal room. Fredda had redecorated it in soft and gentle colors, pastel shades of yellow and white, with soft rugs and comfortable chairs and cheerful abstract murals on the walls. Kresh would not have picked out any of it for himself, and yet, somehow, it all suited him very well. It felt more like a home than any place he had ever lived by himself. Warm, and safe, and bright.

But then Kresh saw the room flash white for a split second as a lightning bolt lit up the window behind him. The thunder came quickly after, a booming roar that seemed powerful enough to shake the room apart.

A well-timed reminder, it was, that they were not safe, that they could build all the buildings and walls and barriers they liked. The world would still be outside, unpredictable, uncontrollable, unknowable.

And why merely imagine the chance of Comet Grieg being spotted earlier? Comet Grieg could just as easily have been left undiscovered until it was much closer, until it was too late to even consider diverting it. Or else the comet’s natural, undiverted orbit could just as easily have been too far off to even contemplate moving it. Or the damned thing could have been heading in for an unplanned, uncontrolled direct hit on the planet. What would they have done then?

But no. “What if” was no longer the question. Alvar Kresh, and Alvar Kresh alone, had to answer another question.

“What now?” he asked Fredda and Donald. “What is to be done?”

There was a long moment’s pause before either of them replied, the rain on the roof a fitting, brooding background to the mood of the room.

“I don’t know,” said Fredda at last. “Either leave the comet alone or bring it in to drop on our heads. Those are the two things you can do. It seems to me that either one could save all the life on the planet from destruction—or actually bring on that destruction. Are we doomed if we do nothing? Can we drop the comet without killing us all?”

Kresh made a thoughtful little noise in his throat. “That’s what it comes down to, isn’t it?” He considered for a moment, and then went on. “Of course, the traditional Spacer response would be to do nothing at all,” said Kresh. “Let it alone, let it pass. If there is no way to know if it would be better to act, why then far better to leave the thing alone. If you do nothing, then there is nothing you can be blamed for if things go wrong.”

“Another proud legacy of the Three Laws,” Fredda said. “Be safe, do nothing, take no chances.”

“If the Three Laws teach humans to avoid taking needless risks now and again, I for one see that as a very strong argument in their favor,” said Donald, speaking for the first time. “But even the First Law contains an injunction against inaction. A robot cannot stand idly by. It must act to prevent harm to humans.”

Kresh looked toward Donald with a smile. “Are you saying that a robot faced with this decision would choose to bring down the comet? Is that what you would do?”

Donald held up his hands palm out and shook his head back and forth vigorously. “By no means, Governor. I am quite literally incapable of making this decision. It would be a physical impossibility for me to do it, and more than likely suicidal to attempt it. So it would be for any properly constructed Three Law robot.”

“How so?”

“The First Law enjoins us against doing harm to humans, and against inaction at such times when robotic action would prevent harm to humans.” Donald’s speech became labored as he spoke. It was plain that even discussing the issues in a hypothetical context was difficult for him. “In this case, both action or inaction might or might not cause or prevent harm to humans. Attempting to deal with such a difficult problem, with the lives of so many present and potential humans in the bal—balance would cause… would cause irreparable damage to any pospospositronic brain, as the question produced cascading First-Law/First-Law conflictzzz.” Donald’s eyes grew a bit dimmer, and his movements seemed oddly sluggish as he put his arms back down at his side.

“All right, Donald,” said Kresh, in his firmest and most reassuring voice. He stepped over to the robot and put his hand on Donald’s sloping shoulder. “It’s all right. You are not the one who will have to make that decision. I order you to stop considering it at this time.” There were times when only the words of a robot’s direct master could be enough to snap the robot out of such a state.

Donald’s eyes faded out all but completely for a moment, and then came back to their normal brightness. He seemed to be looking at nothing at all for a few seconds, but then his eyes began to track again, and he looked straight at Kresh. “Thank—thank you, sir. It was most unwise of me to consider the question so closely, even when called upon to do so.”

Kresh nodded absently, knowing that he had brought it on himself. He had asked Donald why a robot could not make such a decision, and a question was, in essence, an order. It required constant caution, endless care, to deal with the delicacy of a Three-Law robot’s sensibilities and sensitivities. Sometimes Kresh was deeply tired of it all. There were even times when he was ready to concede that the Settlers might have a point. Maybe some parts of life would be easier without robots.

Not as if they had such an option at the moment. But if robots could not be trusted to face such a situation… Kresh turned toward Donald again. “Donald, I hereby order you to turn around and face the wall, and to shut off all your audio inputs until you see my wife or me waving at you. Do you understand?”

“Yes, sir. Of course.” Donald turned his back on Kresh and Fredda. “I have now shut down my audio receptors.”

“Very good,” said Kresh. More damn fool precautions, but that couldn’t be helped. At least now Donald would be unable to hear or eavesdrop. Now they would be able to talk without fear of saying the wrong thing in front of the robot and accidentally setting up a damn fool First Law crisis. Kresh turned toward Fredda. “What about the Robotic Planetary Control Center?” he asked. “I wanted to consult with it—and with the Computational Planetary Control Center—before I reached a decision.”

“Well, what about them?” Fredda asked.

The two control centers were the heart of the reterraforming effort, performing all the calculations and analyses of each new project before it was launched. The original intent had been to build a single control center. There were two basic designs to choose between. One was a Settler-style computational unit, basically a massively complex and powerful, but quite nonsentient, computer. The other was a Spacer-style robotic unit that would be based on a hugely powerful positronic brain, fully imbued with the Three Laws. It would, in effect, be a robot mind without a robot body.

There had been a tremendous controversy over whether to trust the fate of the planet to a mindless machine, or to a robotic brain that would refuse to take necessary risks. It was easy to imagine a robotic control unit choosing to avoid harm to one human, rather than permit a project vital to the future of the planet. The robotics experts all promised that it didn’t work that way, but experts had been wrong before. Governor Grieg had died before he could reveal his choice between the two systems. In one of the first acts of his administration, Kresh had decided to build both, and interconnect them so that the two systems worked in consensus with each other. In theory, if the two systems could not reach agreement on what to do, or not to do, they were to call in human referees to decide the issue. In practice, the two systems had agreed with each other far more often than anyone could have hoped. Thus far, there had only been a half dozen or so very minor issues that had required human decisions.

A vast planetary network of sensors and probes, orbiting satellites, mobile units, and on-site investigators, both robotic and human, fed a constant stream of information to both units—and both units fed back a constant stream of instructions and commands to the humans and robots and automatic machines in the field.

The two interconnected control centers were the only devices on the planet capable of handling the constant stream of incoming data and outgoing instructions. It was plainly obvious that the two of them would have to be consulted regarding the plan to drop a comet on the planet, but Kresh did not wish to risk the sanity of the robotic unit. “You saw what just happened to Donald,” he said. “Will I burn the Robotic Center out if I ask it what I should do?”

Fredda smiled reassuringly. “There wouldn’t be much point in having a Robotic Control Center that couldn’t consider risks to the planet without damaging itself,” she said. “It took some doing, but we installed some special… safeguards, shall we say, that should keep it from experiencing any serious First Law conflict.”

“Good, good,” said Kresh, a bit absently. “At least that’s one less thing to worry about. At least we know that part is all right.”

“Do we?” Fredda asked. “I wonder. When Lentrall asked me about Donald’s name, and how it was not from Shakespeare, that made me wonder.”

“Wonder what?”

“I was absolutely certain it was from Shakespeare. No doubt at all in my mind. I never bothered to double-check, any more than I would have bothered to double-check the spelling of my own name. I thought I knew it—and I was dead wrong.”

“We all make mistakes,” Kresh said.

“Yes, yes, of course,” Fredda said, impatiently. “But that’s not the point. In a sense, it’s a trivial mistake. But it came out of a trusted database. Who knows how long ago the dataset got scrambled, or what else in it is wrong? And if that database can be wrong, lots of other things can be as well. What else is there that we think we know? What other hard fact that we think we have absolutely right will turn out to be absolutely dead wrong? What else do we think we know?”

There was a moment of long and uncomfortable silence.

But uncertainty surrounded all of life. To wait until one was sure was to remain frozen in place until it was too late. “We’ll never be able to answer that question,” said Kresh. He paused for a moment and thought. “You’re thinking like a scientist,” he said. “And up until now, I’ve been thinking like a politician. Maybe it’s time to think like a police officer.”

“I must admit that I do not see how the police viewpoint would be of much use in this situation,” said Fredda.

“Because back when I was a policeman, I knew I didn’t know,” said Kresh. “I knew, on every case, that some knowledge was hidden, and that I would never have absolutely complete or totally accurate information. But I still had to act. I still had to decide. I had to take the facts I had—or thought I had—and ride them as far as they would take me.” He stepped around Donald so he was facing the robot. He waved his hand in front of Donald’s face. “All right, Donald,” he said. “You can turn around and listen now.”

“Thank you, sir,” Donald replied.

Kresh smiled at Donald, then paused a moment and walked to the center of the room. He looked from Donald to Fredda, and then turned around to look at the rainstorm again, to look at nothing at all. “By the time I know enough to decide what to do, it will be too late to decide. Therefore, we will work on the assumption that we are going to divert Comet Grieg. All preparations will go forward as if we were indeed planning to do the job.”

“So we pretend that you’ve decided?” Fredda asked.

“More or less,” Kresh said. “It will buy me some time. I won’t have to decide until it’s actually time to deflect the comet.”

“That’s a dangerous move,” Fredda said. “It’s going to be hard to make all the investment of time and effort and money and then pull back at the last moment.”

“It’s not the best way to do it,” Kresh agreed. “But can you think of any way that’s less bad? That at least gives us time to examine our options?”

“No,” Fredda admitted.

“Then I think we’d better do it my way,” said Kresh.

“That leaves us with a hell of a lot to do,” Fredda said. “There’s the space-side interception and diversion to set up, the targeting to plan, the site survey of wherever the comet’s going to hit, evacuation of people and equipment, emergency preparations for the cities, food stockpiles to lay in—”

“Excuse me, Dr. Leving, but, if I may say so, that is the sort of organizational job I was made to do.”

Kresh smiled. Fredda ought to know that. She had made Donald in the first place. It was as close to a joke as Donald was ever likely to get. “Point taken,” Kresh said. “Donald, I want you to get started on the initial organizational tasks right now. Project management is to be your primary duty, and you are to avoid allowing other tasks to interfere. You are to perform no further personal service for me unless specifically ordered to do so. Report to me via hyperwave in three hours, time as to project status. Thereafter, you are to consult with me as you see fit. Fredda, with Donald tied up, I’m afraid I’m going to have to borrow Oberon as a pilot. I have a feeling Donald would not permit me to do the flying myself in this weather.”

“Absolutely not,” said Donald.

“But—but where are you going at this hour of the night?” Fredda asked.

“Out,” said Kresh. “No one seems to know anything for sure in this whole business. It’s just about time I got some advice from someone who knows what’s going on.”

THERE’S NO LOGICAL reason to make this trip, Kresh told himself as he stepped out of the elevator car into the covered rooftop hangar of his house. And that was true, as far as it went. No doubt Kresh could have gotten all the information he needed by sitting at his own comm panel in his own house.

But there were times when being on the scene, being there in the flesh, was useful. There would be some little detail, something that might have been overlooked, or never noticed at all, if seen only through a viewscreen, or heard through a speaker.

Besides, the journey itself would be of use. There were times when it was important to be alone, to have time to think. Alone even from one’s personal robot, from one’s trusted wife. Alvar Kresh sensed that this was one of those times when he had to be alone—if for no other reason than to remind himself that he would have to make his decision alone. And he would have the duration of the flight all to himself. Fredda’s robot Oberon scarcely counted as company, and besides, he was taking the long-range aircar. It had a separate passenger compartment behind the cockpit. He stepped aboard, and Oberon followed behind him. Kresh took a seat by the port-side window, allowed Oberon to lock and double-check his seat restraint, and then watched as Oberon stepped forward to the pilot’s compartment and shut the hatch behind himself.

Alone. Yes, a very good idea, to be alone. Good to get out of the city, see something—at least a little something—of the planet again, while he was considering its fate. The thought appealed to him as Oberon powered up the aircar and it lifted a half-meter or so off the deck of the hangar. The outer doors opened, and the aircar slowly eased out into the driving rain. If anything, the storm had grown more intense.

Suddenly the aircar was in the middle of the storm, bucking and swaying in the darkness, the rain crashing down on the hull and the ports with incredible violence. Just for a moment, Alvar Kresh would have been just as glad to have stayed at home—but Oberon would not have started the flight if he had not been confident of his ability to deliver Kresh safely to his destination. Kresh certainly would not have been willing to pilot the craft in this sort of weather.

But even as he grabbed at the arms of his seat and braced himself against the bouncing, bone-rattling ride, there was part of him that knew no fear at all, because a robot was at the controls, and robots and danger to humans simply could not exist in the same place. There were few things in the universe in which Alvar Kresh could place absolute faith, but robots were one of them.

But tell that to the weather. The storm boomed and roared outside the long-range aircar as it fought for altitude, the banging and rattling getting worse with every moment. Just at the moment when Kresh was ready to decide his faith in robots was not all that absolute, the aircar broke free, punched a hole in the clouds and climbed out into the clear and placid skies above.

Smooth sailing after the storm, Kresh told himself as he looked down on the storm clouds below. A nice symbol, that. Maybe even a good omen.

But Kresh knew better, of course. When it came to signs and omens, he had no faith at all.

The aircar turned toward the southeast and settled in for its flight to the island of Purgatory.

DAVLO LENTRALL STUMBLED blindly from the aircar and out into the rain-swept darkness of his own front yard. Kaelor stepped out after him, gently threaded his left arm through his master’s right, and led him toward the front door of the house.

Davlo followed half-consciously, barely aware of where he was or what he was doing. He was in shock, that was all there was to it. It had taken some time for the full impact of what had happened to hit him, but now, at last, it had.

The one part of him that was still more or less aware had refused to let the police aircar hover forward into the garage attached to the house, even though there was plenty of room and it would have saved him getting drenched in the rain. No. No. He would not let the police in his house, not even that far. Not if he could help it.

It was irrational, and he knew it, and he didn’t care. Even though he knew perfectly well that the police had been all through the place in his absence, running their security checks and installing their monitoring devices. Even though he knew they would remain just outside his property line, scanning and probing and watching the storming darkness. Even if he knew all that was right, and sensible, given the fact that people with very few qualms about going too far had chosen him for a target. It might well be that the survival of the planet depended on his staying alive—but just at the moment, Davlo Lentrall did not even care about that.

He moved on leaden feet toward his front door, waited while Kaelor opened it for him, bundled him inside, and closed it behind him. He obeyed unresistingly as Kaelor led him to the center of the main parlor and stripped off his sopping-wet outer garments then and there. Kaelor vanished and returned instantly with a stack of towels and a warm blanket. One of the household robots materialized with a mug of something steaming hot. And then the robots left him alone.

Davlo found himself sitting in the main parlor, his hair and skin still damp, bundled up in a blanket, drinking the hot soup without tasting it, staring at the far wall without seeing it.

It had all fallen in. All of it. Davlo Lentrall had never, not once in his life, doubted himself. Never, not once in his life, had he doubted that he was capable of handling whatever life put before him. He was smarter than, sharper than, quicker than, better than other people, and he knew it. He had always known it.

Until today. Until a bunch of faceless kidnappers took him in completely with their tricks to keep him away from his security detail. Until a robot tossed him around like a rag doll, and shoved him under a park bench for safekeeping. Until a police officer whom Davlo would have dismissed as being of only average intelligence had made all the right guesses, all the right moves, taken all the right chances, and put his own life in grave peril, so as to save Davlo.

But even all that, galling as it was, would not have been so bad. But it all served as nothing more than background for the real story, the real humiliation.

Davlo Lentrall had been scared. No. It was time to be honest, at least with himself. He had been terrified. He was still terrified. When the moment had come, when the emergency had popped up from out of nowhere, the Davlo Lentrall of his imagination—the cool, confident, commanding fellow who could handle whatever life threw at him without the least amount of trouble—that Davlo Lentrall had vanished in a puff of smoke.

It didn’t matter that a courageous, in-control Davlo Lentrall would have ended up shoved under that park bench just the same, that there was nothing he could have done from start to finish to change things, no matter how brave or cowardly he was.

It was that the Davlo Lentrall who was smarter and better than all the rest, the Davlo Lentrall with the nerve to tell the planet’s foremost robot designer that she had made a mistake naming her robot, suddenly wasn’t there anymore.

Lentrall had never really known how would react in an emergency, because he had never been in an emergency. But now he knew. From now on, Davlo Lentrall could not help but know that fear could leave him absolutely incapable of action.

Lentrall took another sip of the hot soup, and, for the first time since had arrived home, really noticed where he was, what he was doing. The soup was good, warming, filling.

So he had dropped the ball today. So be it. What did it matter? There was nothing even the bravest man alive could have done that would have made any difference. And did it really matter so much if Commander Justen Devray was the hero of the afternoon? Would anyone even remember this afternoon’s incident, when they wrote the history books? No. They would remember that Dr. Davlo Lentrall had discovered Comet Grieg, and spearheaded the effort that had led to Grieg’s impact, and to the salvation of the planet.

Yes. Yes. Lentrall finished off the last of the soup in a single swallow, and got to his feet. The blanket still wrapped around his body, he made his way to his home office, in the far corner of the ground floor. Yes. Comet Grieg. That was what they would remember, not this afternoon’s foolish humiliation.

And the best way to wipe the memory of today’s disaster from his mind would be to get back to work, immediately, on the Comet Grieg project. Kaelor had been quite right to point out there were a large number of unresolved problems to deal with. No time like the present to deal with them. He could call up the appropriate computer files from here and set to work on them.

It, of course, never so much as crossed Davlo’s mind to consider where, precisely, the computer files actually were. It had never so much as dawned on him that they had an actually physical location, a position in space that held them. They were simply there, in the massively interlinked comm and computer system that interlinked all the comm terminals in the city and all the planet’s outposts of civilization. He could call them up from any place, any time, and set to work on them, whenever he liked.

He had never given the matter much consideration, any more than he would have stopped to remember that the air was there for him to breathe whenever he wanted, or that his household robots knew when to serve him soup.

Lentrall sat down at his home office comm station and activated his files on Comet Grieg. At least he tried to do so.

Because, quite suddenly, it was as if the air wasn’t there for him to breathe anymore.

THE FLIGHT OVER the Great Bay had been smooth as silk, the aircar leaving the storm behind with the coastline. That was not too surprising. The climate people had told Kresh that it was a typical pattern: warm, moist air dumping its moisture the moment it came in contact with the cool, dry air over land. Part of it had to do with the air being forced up by the mountain ranges just inland from the city of Hades. The wind blew the air up the side of the hill, and the higher the air went, the more its barometric pressure dropped and the less moisture it could hold. So the water came out of the air, and it rained. A rain shadow effect, they called it.

But if it could work on the mainland, it could work just as handily on the windward side of an island. Especially a nice, big island like Purgatory. The prevailing winds over the island were from the south. Oberon flew Kresh’s aircar in from the northwest, up and over the central peak of the island—and then right back down into weather every bit as heavy as what they had left behind at Hades.

The aircar dropped down into the clouds, and was instantly engulfed by the raging storm. Kresh grabbed at his armrests again as the aircar bucked and heaved and bounced allover the sky, thunder booming all around as lightning lit up the storm-tossed skies outside his viewport. Suddenly Kresh was caught in the urge to get forward, to get to the cockpit and see what was going on, to grasp hold of the controls and take over. But if that was not panic talking, it was the next best thing.

Kresh forced himself to relax, to ease back. It was going to be all right. Oberon was a good pilot. He looked out the viewport, and down at the rain, far below. He could not help but think back to another storm on Purgatory, five years before. A storm brought on by the weatherfields, the huge forcefields generated at the Terraforming Center. A storm that had raged that night when Chanto Grieg was murdered. At least tonight, in this storm, there was no disaster waiting to strike. Kresh smiled to himself. Talk about misplaced confidence. How the devil could he know what schedules were kept by disasters? They tended to come up whenever they pleased, without bothering to consult the likes of Alvar Kresh.

There was a harder bump than any before, and suddenly the aircar had stopped moving. Startled, Kresh blinked and looked out the viewport. It took him a moment to realize they were on the ground.

The door to the aircar’s cockpit opened and Oberon stepped into the main cabin. “We have arrived, sir,” he said in his low, almost gravelly, voice. “As you can see, sir, the weather is extremely inclement. As there is no covered access between the landing pad and the entrance, perhaps you might wish to wait until the weather has cleared before you set out.”

Kresh peered through the viewport, using his hand to block the glare from the cabin’s interior lights. He spotted the entrance to the Terraforming Center. “It can’t be more than a hundred meters or so to the door,” Kresh said. “Why the devil should I wait?”

“As you see fit, sir. If you think it a wise idea to go immediately.”

Damned busybody nursemaid of a robot. Kresh indulged himself with a brief flash of temper. If he waited around until the weather was just right, would Oberon then hint that he should wait until he had had a full meal and a nice long nap before setting out on the arduous thirty-second journey across the parking lot? They were on the clock here, and he had already been worrying that he had wasted too much time.

“I think it’s a wise idea, all right,” Kresh growled. “In fact I find it downright brilliant.” He undid his seat restraint, got up, and grabbed his rain poncho from the seat opposite, where he had tossed it down after coming aboard. The thing was still a trifle damp, but no matter. He pulled it on over himself, adjusted the hood, and glared at Oberon. “I’d suggest you stay here for the time being,” he said, “unless you think it a wise idea to get in my way.”

Plainly, Oberon did not think it a wise idea to reply to that. Kresh turned his back on the robot, grabbed the hatch handle, and yanked up on it. The hatch unlatched, and Kresh gave it a good hard shove. It swung open and he stepped out into the roaring weather.

The driving rain caught him full in the face, coming down cold and hard. Kresh held up his hand to shield his face, and squinted through the downpour. He walked around to the opposite side of the ship, and then straight ahead, toward the entrance to the Terraforming Center. The wind grabbed at his poncho, blowing it flat against his body and sending its hem flapping and slapping wildly behind him. He leaned into the wind, struggling to hold the poncho hood on top of his head as the wind did its best to pull it off, and the rain blew in regardless.

A pair of big double glass doors, the sort that opened at the center, formed the main entrance of the Terraforming Center. Kresh got to them and almost grabbed at the handles before he realized that wouldn’t work. He wasn’t going to get in unless he followed the rules—rules he had approved himself. “VOICEPRINT!” he shouted above the noise of the storm.

“Auto-voiceprint system ready,” an utterly depersonalized voice replied from nowhere in particular. Even though Kresh had been expecting a reply, it still startled him. The voice was clearly artificial—calm, emotionless, bloodless.

Kresh answered back in a somewhat lower tone of voice. If he could hear the voiceprint, probably it could hear him. “Name—Governor Alvar Kresh,” he said. “Password—Terra Grande.”

“Identity confirmed, clearance to enter confirmed,” the voice replied. The doors unlatched. Kresh, impatient and eager to get out of the rain, grabbed the handles of both doors and pulled them a bit too hard. The wind caught at the left side door and yanked it out of his hand, bouncing it against the left-side wall before it swung back. There was a second, inner pair of doors that swung inward, and Kresh shoved them out of his way without breaking stride.

He had not been here in a long time, but he still knew his way around. He turned left and marched down the main hallway toward the third set of doors. The first two doorways in the hallway were perfectly ordinary affairs, but not the entrance to Room 103. It was a huge, armored steel hatch that more closely resembled the doors of a vault than anything else. The door was locked down and secured, as it should have been, but there was a palmprint button by the side of the door. Kresh slapped his hand down on it. After a moment, there was a bump, a clunk, and a thud and the massive door swung outward.

Kresh ducked inside the moment the door was open wide enough to do so. A startled-looking middle-aged woman in a lab coat was working at a desk just inside the door. She stared open-mouthed at the intruder, then got to her feet. She seemed about to protest, and two or three of the robots took a step or two closer, as if they feared that the intruder might intend harm to the woman. But then Kresh threw back the hood of his poncho. It was clear that the woman and the robots recognized him instantly—but knowing who he was only seemed to increase their sense of bewilderment.

But Alvar Kresh was not much interested in the emotional state of the swing-shift technical staff. He barely looked at them. He looked around until he spotted two huge and gleaming hemispherical enclosures, each about five meters across, each sitting on a plinth or thick pillar, about the diameter of the hemisphere on top of it. The pillars raised the bases of the hemispheres up to just about eye level. One of the hemispheres was a smooth and perfectly rounded dome, the other a geodesic form, made up of flat panels, with all manner of complicated devices and cables and conduits hanging off it at every angle. Kresh nodded at the two machines, and spoke.

“I want to talk to the twins,” he said.

DR. LESCHAR SOGGDON opened her mouth and shut it, then opened it again and left it that way for a moment before she found her voice. “You’re—you’re Governor Kresh,” she said at last.

“Yes,” her visitor replied testily. “I know I am. And I need to talk to the twins concerning some climate projections. Now.”

Soggdon was now at even more of a loss. “Sir, it doesn’t work that way. You can’t just come in and—”

“I can,” Kresh said. “I should know. I wrote the regulations.”

“Oh, yes, yes, sir, of course. I wasn’t suggesting that you were not allowed to come here. It is merely a question of having the training and the understanding of our procedures here. It would probably be wiser for you to submit your questions in writing to the General Terraforming Committee and then—”

“Who are you?” Kresh asked, interrupting her. “What is your position here?”

Soggdon flushed and drew herself up to her full height, bringing her eyes roughly level With the base of Kresh’s neck. “I am Dr. Leschar Soggdon,” she said with as much dignity as she could muster. “I’m the night shift supervisor here.”

“Very well, Dr. Soggdon. Please listen carefully. I have come here precisely for the reason that I want—I need—to avoid that sort of delay and caution. I am here on a matter of the greatest urgency and importance, and I must be certain I am getting my information direct from the source. I cannot take the chance of some expert misinterpreting my questions or the answers from the twins. I cannot wait for the General Committee to have a conference and debate the merits and the meaning of my questions. I have to ask my questions now, and get an answer now. Is that clear? Because if it is not, you’re fired.”

“I ah—ah—ah, sir, I ah—”

“Yes? Do you have other job prospects?”

She swallowed hard and started again. “Very well,” Soggdon said at last. “But, sir, with all due respect, I would ask that you sign a statement that you proceeded against my advice and specifically ordered me to cooperate.”

“I’ll sign whatever you like,” Kresh said. “But right now let me talk to the twins.” The governor peeled off his poncho and handed it to the nearest robot. He walked to the far side of the huge room, where the two massive hemispherical enclosures sat. Inside were the two Terraforming Control Centers, one a Spacer-made sessile robotic unit, and the other a Settler-made computational system.

A sort of combination desk and communications console sat facing the two machines. Governor Kresh pulled out the chair and sat down at it. “All right, then,” he said. “What do I do?”

Soggdon was severely tempted simply to show the man the proper controls to operate and let him charge ahead as directly as he liked. But she knew just how much damage even a minor slip of the tongue could produce. The idea of having Unit Dee caught in a major First Law conflict just because Kresh wanted to have his own way was too much for her. She had to speak up. “Sir,” she said, “I’m sorry, but you have to understand a few things before you start, and I’m going to make sure you understand them, even if it means I lose my job. Otherwise you could cause any amount of damage to Unit Dee.”

Kresh looked up at her in annoyed surprise, but then his expression softened, just a bit. “All right,” he said. “I always tell myself that I prefer it when people stand up to me. I guess this is my big chance to prove it. Tell me what I should know, but don’t take too long about it. You can start by telling me what ‘D’ means.”

His question took her by surprise. Soggdon looked at him carefully before she spoke. How could a man who didn’t even know what—or who—Unit Dee was expect to barge in here and take over? “I didn’t mean the letter ‘D,’ sir. I meant Unit Dee. That’s what we call the robotic terraforming control unit. Unit Dee.”

Kresh frowned and looked over at the two units, and seemed to notice for the first time the two neatly lettered signs, one attached to each of the two hemispheres. The sign on the front of the rounded-off dome read Unit Dee, and the one on the angular geodesic dome read Unit Dum.

“Ah. I see,” he said. “I confess I don’t know much about how you run things here. I visited here once or twice during construction, but not since you’ve been operational. I know the code name for the two Control Units is still ‘the twins’—but not much else. I suppose those names stand for something. Acronyms?”

Soggdon frowned. For someone determined to charge in here and take over, he certainly was ready to get distracted by side issues. “I believe the name Unit Dee referred to the fourth and final design considered. From there it seemed to develop into a sort of private joke among the day shift staff,” she said. “I must confess I never bothered to find out what the joke was. It might have something to do with Unit Dum being, well, dumb, nonsentient, but I’ve never understood the exact significance of Unit Dee.” Soggdon shrugged. She had never been much known for her sense of humor.

“All right,” said the governor. “All that to one side,” he went on, “what do I need to know to avoid producing damage to the twins?”

“Well, Unit Dee is the only one likely to suffer damage. Unit Dum is a non sentient computation device, not a robot. He has a pseudo-self-aware interface that allows him to converse, to a limited extent, but he’s not a robot and he’s not subject to the Three Laws. Unit Dee is a different story. She’s really not much more than an enormous positronic brain hooked up to a large number of interface links. A robot brain without a conventional robot body—but she is, for all intents and purposes, a Three-Law robot. Just one that can’t move.”

“So what is the difficulty?” Kresh demanded, clearly on the verge of losing his patience again.

“That should be obvious,” Soggdon replied, realizing just a second too late how rude a thing that was to say. “That is—well, my apologies, sir, but please consider that Unit Dee is charged with remaking an entire planet, a planet that is home to millions of human beings. She was designed to be capable of processing truly huge amounts of information, and to make extremely long-range predictions, and to work at both the largest scale and the smallest level of detail.”

“What of it?”

“Well, obviously, in the task of remaking a planet, there are going to be accidents. There are going to be people displaced from their homes, people who suffer in floods and droughts and storms deliberately produced by the actions and orders of these two control systems. They will, inevitably, cause some harm to some humans somewhere.”

“I thought that the system had been built to endure that sort of First Law conflict. I’ve read about systems that dealt with large projects and were programmed to consider benefit or harm to humanity as a whole, rather than to individuals.”

Soggdon shook her head. “That only works in very limited or specialized cases—and I’ve never heard of it working permanently. Sooner or later, robotic thinking machines programmed to think that way can’t do it anymore. They burn out or fail in any of a hundred ways—and the cases you’re talking about are robots who were expected to deal with very distant, abstract sorts of situations. Unit Dee has to worry about an endless series of day-by-day decisions affecting millions of individual people—some of whom she is dealing with directly, talking to them, sending and receiving messages and data. She can’t think that way. She can’t avoid thinking about people as individuals.”

“So what is the solution?” Kresh asked.

Soggdon took a deep breath and then went on, very quickly, as if she wanted to get it over with as soon as possible. She raised her hand and made a broad, sweeping gesture. “Unit Dee thinks this is all a simulation,” she said.

“What?” Kresh said.

“She thinks that the entire terraforming project, in fact the whole planet of Inferno, is nothing more than a very complex and sophisticated simulation set up to learn more in preparation for a real terraforming project some time in the future.”

“But that’s absurd!” Kresh objected. “No one could believe that.”

“Well, fortunately for us all, it would seem that Unit Dee can.”

“But there’s so much evidence to the contrary! The world is too detailed to be a simulation!”

“We limit what she can see, and know, very carefully,” Soggdon replied. “Remember, we control all of her inputs. She only receives the information we give her. In fact, sometimes we deliberately introduce spurious errors, or send her images and information that don’t quite make sense. Then we correct the ‘mistakes’ and move on. It makes things seem less real—and also establishes the idea that things can go wrong. That way when we do make mistakes in calculations, or discover that we’ve overlooked a variable, or have just plain let her see something she shouldn’t have, we can correct it without her getting suspicious. She thinks Inferno is a made-up place, invented for her benefit. So far as she knows, she is actually in a laboratory on Baleyworld. She thinks the project is an attempt to learn how to interact with Settler hardware for future terraforming projects.” Soggdon hesitated for a moment, and then decided she might as well give him the worst of the bad news all at once. “In fact, Governor, she believes that you are part of the simulation.”

“What!”

“It was necessary, believe me. If she thought you were a real person, she would of course wonder what you were doing in the made-up world of her simulation. We have to work very hard to make her believe the real world is something we have made up for her.”

“And so you had to tell her that I did not really exist.”

“Precisely. From her point of view, sapient beings are divided into three groups—one, those who exist in the real world, but don’t have anything to do with her; two, real-world people here in the lab and in the field who talk with her and interact with her—and three, simulants, simulated intelligences.”

“Simulants,” Kresh said, very clearly not making it into a question. He was ordering her to explain the term, not asking her to do so.

“Ah, yes, sir. That’s the standard industry term for the made-up humans and robots placed in a simulation. Unit Dee believes that the entire population of Inferno is really nothing more than a collection of simulants—and you are a member of that population.”

“Are you trying to tell me I can’t talk to her because she’ll realize that I’m not made-up?” Kresh asked.

“Oh, no, sir! There should be no problem at all in your talking with Unit Dee. She talks every day with ecological engineers and field service robots and so on. But she believes them all to be doing nothing more than playing their parts. It is essential that she believe the same thing about you.”

“Or else she’ll start wondering if her simulated reality is actually the real world, and start wondering if her actions have caused harm to humans,” said Kresh.

“She has actually caused the death of several humans already,” Soggdon replied. “Unavoidably, accidentally, and only to save other humans at other times and places. She has dealt reasonably well with those incidents—but only because she thought she was dealing with simulants. And, I might add, she does have a tendency to believe in her simulants, to care about them. They are they only world she’s ever known.”

“They are the only world there is,” said Kresh. “Her simulants are real-life people.”

“Of course, of course, but my point is that she knows they are imaginary, and yet has begun to believe in them. She believes in them in the way one might care about characters in a work of fiction, or the way a pet owner might talk to her nonsentient pet. On some level Unit Dee knows her simulants are not real. But she still takes a genuine interest in them, and still experiences genuine, if mild, First Law conflict when one of them dies and she might, conceivably, have prevented it. Causing the death of simulants has been extremely difficult for her.

“If she were to find out she had been killing real people—well, that would be the end. She might simply experience massive First Law conflict and lock up altogether, suffer brainlock and die. Or worse, she might survive.”

“Why would it be worse if she survived?” Kresh asked.

Soggdon let out a long weary sigh and shook her head. She looked up at the massive hemisphere and shook her head. “I don’t know. I can guess. At best, I think she would find ways to shut down the whole operation. We’d try to stop her, of course, but she’s too well hooked in, and she’s awfully fast. I expect she’d order power shutdowns, find some way to deactivate Unit Dum so he couldn’t run the show on his own, erase computer files—that sort of thing. She’d cancel the reterraforming project because it could cause injury to humans.”

“The best sounds pretty bad. And at worst?”

“At worst, she would try to undo the damage, put things back the way they were.” Soggdon allowed herself a humorless smile. “She’d set to work trying to un-reterraform the planet. Galaxy alone knows what that would end up like. We’d shut her down, of course, or at least try to do so. But I don’t need to exaggerate the damage she could do.”

Kresh nodded thoughtfully. “No, you don’t,” he said. “But I still need to talk with her—and with Unit Dum. You haven’t said much about him, I notice.”

Soggdon shrugged. “There’s not much to say. I suppose we shouldn’t even call him a he—he’s definitely an it, a soulless, mindless, machine that can do its job very, very, well. When you speak with him, you’ll really be dealing with his pseudoself-aware interface, a personality interface—and, I might add, it is quite deliberately not a very good one. We don’t want to fool ourselves into thinking Unit Dum is something he is not.”

“But it sounds as if he could handle the situation if Unit Dee did shut down.”

“In theory, yes, Unit Dum could run the whole terraforming project by himself. In practice, all of us here believe you were quite wise not to put all your trust in a single control system. We need redundancy. We need to have a second opinion. Besides which, the two of them make a good team. They work well together. They are probably three or four times as effective working together as either would be alone. And anyway, we’re only a few years into a project that could take a century or more. It’s way too early to think about risking our primary operating procedure and trusting the whole job to backups. What if the backup runs into trouble?”

“All your points are well taken,” said Governor Kresh. “So—what are the precautions I should take in talking to them?”

“Don’t lose your temper if Unit Dee is condescending to you in some way. She doesn’t really think you’re real, after all. You are really nothing more than one of the game pieces, as far as she is concerned. Don’t be thrown off if she seems to know a great deal about you, and lets you know it. Don’t correct her if she gets something wrong, either. We’ve made various adjustments to her information files for one reason or another—some deliberate errors to make it seem like a simulation, and others we set up for some procedural reason or another. Try to remember you’re not real. That’s the main thing. As for the rest of it, you’ll be talking to her via audio on a headset, and I’ll be monitoring. If there’s anything else you need to know, I’ll cut in.”

Governor Kresh nodded thoughtfully. “Have you ever noticed, Dr. Soggdon, just how much of our energy goes into dealing with the Three Laws? Getting around them, trying to make the world conform to them?”

At first, the offhand remark shocked Soggdon. Not because she disagreed with his words—far from it—but because Kresh was willing speak them. Well, if the governor was in a mood to dabble with heresy, why not indulge in it herself? “I’ve thought that for a long time, Governor,” she said. “I think the case could be made that this world is in as much trouble as it is because of the Three Laws. They’ve made us too cautious, made us worry too much about making sure today is like yesterday, and far too timid to dare plan for tomorrow.”

Kresh laughed. “Not a bad line, that,” he said. “You might catch me stealing it for use in a speech one of these fine days.” The governor looked from the Unit Dee Controller to the Unit Dum Controller, and then back up at Soggdon. “All right,” he said. “Let’s get this thing set up.”

“GOOOD MORRN-ING. GOVVVENORR Kressh.” Two voices came through the headphone to address him in unison—one a light, feminine soprano, the other a gravelly, slightly slurred, and genderless alto. They spoke the same words at the same time, but they did not synchronize with each other exactly.

The voices seemed to be coming from out of nowhere at all. No doubt that was an audio illusion produced by the stereo effect of the headphones, but it was nonetheless disconcerting. Alvar Kresh frowned and looked behind himself, as if he expected there to be two robots there, one standing behind each ear. He knew perfectly well there would be nothing to see, but there was some part of him that had to check all the same.

The whole setup seemed lunatic, irrational—but the iron hand of the Three Laws dictated that there be some such arrangement. Kresh decided to make the best of it. “Good morning,” he said, speaking into the headset’s microphone. “I take it I am addressing both Unit Dee and Unit Dum?”

“Thaat izz comect, Governorrr,” the two voices replied. “Somme vizzzitors finnnd iiit dissconcerrrting to hear usss both. Shalll we filllter ouut onne voice?”

“That might be helpful,” Kresh said. Disconcerting was far too mild a word. The two voices speaking as one was downright eerie.

“Very well,” the feminine voice said in his left ear, by itself, speaking with a sudden brisk, clipped tone, a jarring change from what had come before. Perhaps she found it easier to speak without the need to synchronize with Unit Dum. “Both of us are still on-line to you, but you will hear only one of us at a time. We will shift from one speaker to the other from time to time to remind you of our dual presence.” The voice he heard was almost excessively cheerful, with an oddly youthful tone to it. A playful voice, full of amusement and good humor.

“This higher-pitched voice I hear now,” Kresh said, “it is Unit Dee?”

“That is correct, sir.”

Suddenly the other voice, low-pitched, impersonal and slightly slurred, spoke into his right ear. “This is the voice of Unit Dum.”

“Good. Fine. Whatever. I need to speak with you both.”

“Please go ahead, Governor,” said Unit Dee in his left ear again. Kresh began to wonder if the voice-switching was some sort of game Unit Dee was playing, a way of putting him off his stride. If so, it was not going to work.

“I intend to,” he said. “I want to talk to you about an old project, from the period of the first effort to terraform this world.”

“And what would that be?” asked Unit Dee.

“The proposal to create a Polar Sea as a means of moderating planetary temperatures. I want you to consider an idea based on that old concept.”

“Ready to accept input,” said the gravelly, mechanical voice in his right ear. It was plain that very little effort had gone into giving Unit Dum a simulated personality. That was, perhaps, just as well. Kresh had the sense of talking to a schizophrenic as it was.

“Here is the idea. Assume that, in the present day, the existing Polar Depression were flooded, with inlets to the Southern Ocean provided by cutting a canal through the Utopia region on the eastern side of Terra Grande, and by redirecting the flow of the River Lethe in the west. Assume the work could be done very rapidly, within a few years’ time.”

There was the briefest of pauses. “This would cause a Polar Sea to form,” Unit Dum went on. “However, the concept is implausible. There is no way of performing such an enormous engineering task in any practical length of time.”

“Even if we could do it, I’m sure the collateral damage to existing ecosystems and property would be huge,” said Unit Dee, clearly talking more to Unit Dum than to Kresh.

“Current projections show the issues of damage to ecosystems and property become moot in between two and two point five standard centuries,” Unit Dum replied.

“Why do they become moot?” Kresh asked, fearing the answer.

“Because,” Unit Dee replied, her voice clearly unhappy, “our current projection shows all ecosystems collapsing and all humans—the owners of the property—either dying or being evacuated from the planet by that time.”

Kresh was genuinely surprised. “I was not aware that the numbers were that bad. I thought we at least had a chance at survival.”

“Oh, yes,” said Unit Dee. “There is at least a chance human life will survive here. That is in large degree a matter of choice for your descendants. Human beings can survive on a lifeless, airless, sterile ball of rock if they choose to do so. If the city of Hades were domed over or rebuilt underground, and properly shielded, it could no doubt sustain a reduced population indefinitely after the climate collapses.”

“But things are improving,” Kresh protested. “We’re turning things around!”

“So you are—for the moment, in localized areas. But there is little or no doubt that the current short-term improvements cannot be sustained and extended in the longer term. There is simply not enough labor or equipment to expand the zones of improved climate far enough, and establish them firmly enough, for them to be self-sustaining.”

“And therefore there is no real point in worrying over ecological damage or property loss,” Kresh said. “Fine. Disregard those two points—or, rather, factor in the results of attempting to deal with them, of efforts to repair the damage.”

“The calculation involves a near-infinite number of variables,” said Unit Dum. “Recommend a pre screening process to select range of near best-case scenarios and eliminate obviously failed variants.”

“Approved,” Kresh said.

“Even the prescreening process will take a few minutes,” said Unit Dee. “Please stand by.”

“As if I had much choice,” Kresh said to no one in particular. He sat there, looking from Unit Dee’s smooth and perfect hemispherical enclosure to the boxy, awkward, hard-edged looking enclosure around Unit Dum. Dum’s enclosure, or containment, or whatever, at least had the merit of looking like machinery. Dum looked like it did something, was hooked into things, made things happen. It was hardware and wires. It was solid, firmly attached to reality by power cables and datastreams. Dum was of this world.

In many more senses than one, Dee plainly was not. She was sheltered from the rude outside universe. She was the smooth and perfect one, sealed off in her idealized containment enclosure that needed special treatment. Dee looked more like an abstract sculpture than a working robot. She looked liked something that was supposed to stand off, aloof, on her own, a divine being or magic totem to be consulted rather than a machine meant to do work. And was that so far off? Kresh glanced at Soggdon on the far side of the lab, pretending to be puttering around with something or other while she kept a nervous, unhappy eye on Kresh.

Yes, indeed. Unit Dee had her acolytes, her priests, who ministered to her whims and did their best to rearrange the world to suit her convenience, who walked on eggshells rather than anger or upset the divine being on whom all things depended. Kresh thought suddenly of the oracles of near-forgotten legend. They had been beings of great power—but of great caprice and trickery as well. Their predictions would always come true—but never in the way expected, and always at an unexpected price. Not a pleasant thought.

“I believe we are ready to begin with the main processing of the problem,” Dee said, her voice coming so abruptly into the silence that Kresh jumped ten centimeters in the air. “Would you care to observe our work?” she asked.

“Ah, yes, certainly,” said Kresh, having no idea what she had in mind.

The lights faded abruptly, and, flashing into being with the silence and suddenness of a far-off lightning strike, a globe of the planet Inferno appeared in the air between Kresh’s seat at the console and the enclosures for the two control units.

The globe was a holographic image, about three meters in diameter, showing the planet’s surface with greater precision than Kresh had ever seen. Every detail was razor-sharp. Even the city of Hades was clearly visible on the shores of the Great Bay. Kresh had the feeling that if he stepped up close enough to the globe and peered intently enough, he would be able to see the individual buildings of the city.

Inferno was a study in blue ocean and brown-and-tan land, with a pathetically few dots and spots of cool and lovely green visible here and there on the immense bulk of Terra Grande. Kresh tried to tell himself that they were making progress, that it was something just that their efforts were on a large enough scale to be plainly visible from space. But he wasn’t all that convincing, even to himself. Somehow, over the last few days, it had come home to him that the great efforts they had made were as nothing, that the noble progress he had been so proud of scarcely represented forward movement.

But he did not have time to consider long. The globe turned over on its side, so that the northern polar regions were facing Kresh directly. Then, as he watched, the landscape began to change, shift, mutate. The River Lethe, a thin blue line running from the mountains west of the Great Bay, suddenly widened, and a new line of blue began to cut its way toward the Polar Depression, until the combined canal and river cut through the length of Terra Grande. Yes, Kresh could see it. Dredge the canal deep enough to allow a flow into the upper reaches of the Lethe, takes steps to make sure the channel scoured itself deeper instead of silting over, and it would work. Water would flow from the Polar Sea into the Great Bay. Assuming there was a Polar Sea, of course. At the present time, as shown in the simulation, there was nothing but dull white ice, a significant fraction of the planetary water supply locked up in the deep freeze where it could do no one any good.

But Dum and Dee were far from done with their modeling. Kresh looked to the western regions of Terra Grande. It was plain that things were not quite so simple or straightforward there. Again and again, a wedge-shaped channel of blue water appeared. The northernmost portion of its channel constantly shifted position, widened, narrowed, expanded, contracted, vanished altogether for a moment and then reappeared somewhere else. Plainly, the two control units were searching for the optimum positioning of the channel.

At long last the image settled down to a wide channel cutting straight north through the Utopia region. Kresh shook his head and swore under his breath. The optimum channel the two control units had chosen followed almost exactly the same path Lentrall had shown him. Maybe the pushy young upstart did know what he was talking about.

“Channel pattern as presented within one percent of theoretical optimum configuration,” Unit Dum announced. “That figure is well inside accumulated combined uncertainty factors of many variables.”

“In other words, it is as close as we can get right now—and very much close enough for a first approximation,” said Unit Dee. “We are now ready for preliminary long-range climate calculation.”

Kresh half-expected to see the planet’s surface evolve and change, as he had seen so many times before on simglobes and other climate simulators. And he did see at least a little bit of that—or thought he did. But the globe itself was covered in a blizzard of layered data displays that sprawled over its surface. Isobar mappings for temperature, air pressure, humidity, color-coded scatter diagrams of populations for a hundred different species, rainfall pattern displays, seasonal jet-stream shifts, and a dozen other symbol systems Kresh couldn’t even begin to recognize, all of them shifting, rising, dropping, interacting and reacting with each other, a storm of numbers and symbols that covered the planet. The changes came faster and faster, until the symbols and numbers and data tags merged into each other, blurred into a faintly flickering cloud of gray that shrouded the entire planet.

And then, in the blink of an eye, it stopped. The cloud of numbers was gone.

A new planet hung in the air before Kresh. One in which the old world could be clearly seen, and recognized, but new and different all the same. Alvar Kresh had seen many hypothetical Infernos in his day, seen its possible futures presented a hundred times in a hundred different ways. But he had never seen this Inferno before. The tiny, isolated, spots of green here and there were gone, or rather grown and merged together into a blanket of cool, lush green than covered half of Terra Grande. There were still deserts, here and there, but they were the exception, not the rule—and even a properly terraformed planet needed some desert environments.

The sterile, frozen, lifeless ice of the northern polar icecap had vanished completely, replaced by the Polar Sea, a deep-blue expanse of life-giving liquid water. Even at this scale, even to Kresh’s untrained eye, he could see that sea levels had raised worldwide. He wondered for a moment where the water had come from. Had the control units assumed that the importation of comet ice would continue? Or was the water-level rise caused by thawing out the icecaps and breaking up the permafrost? No matter. The fact was that the water was there, that life was there.

“That’s the best, most positive projection I’ve ever seen,” Soggdon said. Kresh, a trifle startled, turned and looked over his shoulder. She was standing right behind his chair, gazing at the globe display in astonishment. “Hold on. I want to do a blind feed of the audio to your headset.”

“What’s a blind feed?” Kresh asked.

Soggdon picked up a headset identical to the one Kresh wore. Soggdon looked to Kresh as she put them on. “Dee and Dum will think you cannot hear what they say to me. When she talks to you, she is talking to a simulant. When she talks to me, a real human being, she cuts all links to any simulants, so as not to complicate the experiment by letting the simulants hear things they shouldn’t. In reality you’ll be able to hear it. But it is important—vitally important—that you have no reaction to what she says to me, or vice versa. In Dee’s universe, you are just a simulated personality inside a computer. I am a real person outside the computer. You have no way of knowing I exist. Do you understand?”

“Yes,” said Kresh, hoping he did. He had the sense that he had stepped into a hall of mirrors. It was getting hard to tell the fantasies from the realities.

“Good,” said Soggdon, and turned on the manual switch on her headset. “Dee, Dum—this is Soggdon monitoring from outside the simulation.”

“Good mornnning, Doctor. Weee havvve beeen connnversssing with the Kresh simulllannt. “ The two voices spoke in unison again, but Soggdon did not seem to be bothered by it. Having heard each voice by itself, Kresh was able to notice something that had escaped him before. When the two units spoke in unison, it was not merely the two chanting together. The voice of the two together spoke in a cadence that did not belong to either of the two speaking by itself. The unison voice made different word choices, responded in a way that was different from Dee or Dum. The unison voice was not merely two beings talking as one. It was the two merging into one new being, in some ways greater, in some ways lesser than the sum of its parts. Dee and Dum linked so intimately that they became a third, and distinct, personality. Or was it merely Dee who did so? If Dum was truly nonsentient, then he could have no personality. Plainly there were mysteries to delve into—but just as plainly they would have to wait for another day. “The Kresh simulant asked us to consider the result of producing a Polar Sea.”

“Yes, I know,” said Soggdon. “And I see you have produced an impressive planetary projection as a result. Would either or both of you care to comment on it?”

“Both willl speeak, and then eachhh,” said the unison voice. “We havvve prrojected forward four ttthousand yearss, as we have found that a wellll-planned operrational sequenzzze will result in a zzzero-maintenance planetary ecologggy within apprrroximately three hundred years. In our projection, the planetary climmmate remainss intrinsically stable, selfffcorrecting, and self-enhancing throughout the period of the metasimulation. There is no apparent danger of recollapse evident in any of the data for the end of the metasimulation period.”

Kresh frowned. Metasimulation? Then he understood. The unison voice was using the term to refer to a simulation inside a simulation—which was what it had been, so far as Dum and Dee were concerned.

Dum spoke next. “Reference to unit Dum’s prior objections in regard to ecological and economic damage. Projections show that the damage to the general ecology and gross planetary product caused by digging inlets for the Polar Sea would be fully compensated for within fifteen years of project completion.”

But if the first two aspects of the combined control system made it all seem wonderful, the third voice pulled everything back down to reality. “It all sounds quite splendid,” said Dee. “There is, of course, the slight problem of it being quite impossible. We ran the metasimulation based on the assumption that it would be possible to dig the channels. It is not possible to dig them. An interesting exercise, I grant you—but it is not one that has a great deal of connection to the world of our simulation.”

“I was afraid she was going to say that,” Soggdon muttered as she switched off her mike. “You’d think she’d be the least sensible of the three possible personality aspects, but instead Dee’s always the one to stick the pin in the balloon. She always reminds us of the practicalities.”

“Maybe this time they’re a bit more possible than you think,” Kresh said. He keyed his own mike back on, and tried to phrase things so that he would not reveal that he had overheard the conversation with Soggdon.

“Unit Dee, that’s a very promising projection there. I take it you think creating the Polar Sea would be a good idea?”

“It is a good idea that cannot be realized, Governor,” said Unit Dee. “You do not have the resources, the energy sources, or the time to construct the needed inlets.”

“That is incorrect,” Kresh said. “It is possible there is a practical, doable, way to dig those inlets. I came here to have you evaluate the proposed procedure. I first wanted to see if the effort would be worthwhile. I see now that it would be.”

“What is the procedure in question?” asked Unit Dee.

Kresh hesitated a moment, but then gave up. There was no way to describe the idea that didn’t sound dangerous, desperate, even insane. Well, maybe it was all three. So be it. “We’re going to break a comet up, and drop the fragments in a line running from the Southern Ocean to the Polar Depression,” he said. Even as he spoke, he realized that he hadn’t put any modifiers or conditionals in. He hadn’t said they might, or they could, or they were thinking of it. He had said they were going to do it. Had he made up his mind without knowing it?

But Dum and Dee—and Soggdon—plainly had more on their minds than Kresh’s reaction to his own words. There was dead silence for a full thirty seconds before any of them reacted. The perfect holographic image of the Inferno of the future flickered and wavered and almost vanished altogether before it resolidified.

Unit Dee recovered first. “Am I to under—under—understand that you intend this as a serious idea?” she asked. The stress in her voice was plain, her words coming out with painful slowness.

“Not good,” said Soggdon, her headset mike still off. She turned toward a side console, paged through several screenfuls of information, and shook her head. “I warned you she took her simulants seriously,” she said. “These readings show you’ve set off a mild First Law conflict in her. You can’t just come in here and play games with her, make up things like that.”

Kresh cut his own mike. “I’m not making things up,” he said. “And I’m not playing games. There is a serious plan in motion to drop a fragmented comet on the Utopia region.”

“But that’s suicidal!” Soggdon protested.

“What difference does it make if the planet’s going to be dead in two hundred years?” Kresh snapped. “And as for Dee, I suggest it is time you start lying to her in earnest. Remind her it’s all a simulation, an experiment. Remind her that Inferno isn’t real, and no one will be harmed.”

“Tell her that?” Soggdon asked, plainly shocked. “No. I will not feed her dangerous and false data. Absolutely not. You can tell her yourself.”

Kresh drew in his breath, ready to shout in the woman’s face, give her the dressing-down she deserved. But no. It would do no good. It was plainly obvious that she was not thinking with the slightest degree of rationality or sense—and he needed her, needed her help, needed her rational and sensible. She was part of the team that had set up this charade. She was the one who would have to prop it up. He would have to reason with her, coolly, calmly. “It would do no good for me to tell her any such thing,” he said. “She thinks I’m a simulant. Simulants don’t know they are simulants. She would not believe me telling her there was no danger—because she does not believe me to be human. And she does not believe that because you have lied to her.”

“That’s different. That’s part of the experiment design. It’s not false data.”

“Nonsense,” Kresh said, a bit more steel coming into his voice as the gentleness left it. “You have set up this entire situation for the sole purpose of allowing her to take risks, to do her job, while believing she could no harm to humans.”

“But—”

Kresh kept talking, rolling right over her protests. “I could even do damage to her if I told her it was just a simulation. There must be some doubt in her mind as to whether her simulants—the people of Inferno—are real. Otherwise she would not be experiencing the slightest First Law conflict concerning them. If I assured her that I was not real, Space alone knows what she would make of that paradox. It seems to me as likely as not that she would reach the conclusion that I was real, and that I was lying to her. If I lie to her, she might realize the truth—and then where would you be, Dr. Soggdon? Only you can do it. Only you can reassure her. And you must do it.”

Soggdon glared at Kresh, the anger and fear plain on her face as she switched on her mike again. “Dee, this is Dr. Soggdon. I am still monitoring the simulation. I am detecting what appear to be First Law conflicts in the positronic pathing display. There is no First Law element to the simulated circumstances under consideration.” Soggdon hesitated, made a face, and then spoke again. “There is absolutely no possibility of harm to human beings,” she said. “Do you understand?”

There was another distinct pause, and Kresh thought he detected another, but much slighter, flicker in the image of the Inferno that was to be. But then Dee spoke again, and her voice was firm and confident. “Yes, Doctor Soggdon. I do understand,” she said. “Thank you. Excuse me. I must return to my conversation with the simulant governor.” Another pause, and then Dee was speaking to Kresh. “I beg your pardon, Governor. Other processing demands took my time up for the moment.”

“Quite all right,” Kresh said. Of course, Dee was no doubt linked to a thousand other sites and operations, and probably having a dozen other conversations with field workers right now. It was not quite a little white lie, but it was certainly close enough to being one. Robots were supposed to be incapable of lying—but this one was clever enough to manage a truthful and yet misleading statement. Dee was a sophisticated unit indeed.

“Can you tell me more about this… idea under discussion?” Dee asked him.

“Certainly,” said Kresh. “The idea is to evacuate everyone from the target area, and provide safeguards for the population outside the target area.” It could not hurt to emphasize safety procedures first off. Let her know that even the fictional simulants would be safe. They needed as many defenses as possible against a First Law reaction. “Once that is accomplished, a large comet is to be broken up and the fragments targeted individually, the overlapping craters running through existing lowlands. More conventional earth-moving will no doubt be required afterwards, but the linked and overlapping craters will form the basis for the Utopia Inlet.”

“I see,” Dee replied, her voice still strained and tense. “Unit Dum and I will require a great deal more information before we can evaluate this plan.”

“Certainly,” said Kresh. He pulled a piece of paper out of his tunic and unfolded it. “Refer to network access node 4313, identity Davlo Lentrall, subgroup 919, referent code Comet Grieg.” Lentrall had given him the access address earlier. Now seemed the moment to put it to good use. “Examine the data there and you will be able to do your evaluations,” said Kresh.

“There is no identity Davlo Lentrall on access node 4313,” Dee said at once.

“What?” said Kresh.

“No one named Davlo Lentrall is linked into that access node,” said Dee.

“The number must be wrong, or something,” said Kresh.

“Quite likely,” said Dee. “I’m going to hand off to Dum. He is directly linked to the network in question and can perform the search more effectively.”

“There is no Davlo Lentrall on node 4313,” Dum announced, almost at once, speaking in an even flatter monotone than usual. “Searching all net nodes. No Davlo Lentrall found. Searching maintenance archives. Information on identity Davlo Lentrall discovered.”

“Report on that information,” Kresh said. How could Lentrall’s files have vanished off the net? Something was wrong. Something was seriously and dangerously wrong.

“Network action logs show that all files, including all backups, linked to the identity Davlo Lentrall, were invasively and irrevocably erased from the network eighteen hours, ten minutes, and three seconds ago,” Unit Dum announced.

Kresh was stunned. He looked to Soggdon, not quite knowing why he hoped for an answer from that quarter. He switched off his mike and spoke to her. “I don’t understand,” he said. “How could it all be erased? Why would anyone do that?”

“I don’t know,” she said. “He used a term I’m not familiar with in this context. Let me check.” She keyed on her own mike again. “Dum, this is Soggdon, monitoring. Define meaning of the term ‘invasive’ in present situation.”

“Invasive—contextual definition: performed by an invader, an attack from the outside, the act of an invader.”

“In other words,” said Kresh, his voice as cold and hard as he could make it, “someone has broken in and deliberately destroyed the files.” He suddenly remembered what Fredda had said, about the things you thought you knew. She had said something about never really being sure about what you knew. Here it was, happening again. He had thought he knew where the comet was. Now he knew he did not. “It would seem,” he said, “that someone out there agrees with you, Dr. Soggdon. They don’t want anyone playing with comets.”

11

“IT’S GONE, GOVERNOR,” said Davlo Lentrall. “Everything I’ve ever worked on is gone.” He was glad to be speaking over an audio-only link to the governor. Kresh had called on an audio link because it was easier to maintain a secure line that way, but Davlo didn’t care about that. He was simply glad he did not have to show his face. It was bad enough that Kresh could hear the panic in his voice. He wouldn’t want anyone to see him this way. Davlo Lentrall paced frantically up and down in front of his comm center. “All my core files, all the backups, everything.”

“Take it easy, son. Easy now. There must be some way to retrieve it all. I thought the system was designed to make it impossible to lose things irretrievably.”

Davlo tried to calm himself. Kresh had called from—from wherever he was—just as Davlo had finally, absolutely confirmed that all was lost. It was no easy thing to talk to the planetary leader when he was at his lowest ebb.

“Normally, yes, sir. But this wasn’t an accident. This was sabotage. Five minutes after I discovered that my files were gone, I got a call from University Security. Someone broke into my office there and threw in a firebomb. They think there were at least two separate break-ins. By the end of the second intrusion, everything that wasn’t stolen was bummed. They say there’s nothing left. Nothing at all. All my notes and work—including the comet data. The comet coordinates, the tracking information, the orbital projections—everything.”

“Burning stars,” Kresh’s voice half whispered. “Maybe that whole escapade at Government Tower was just a diversion.”

Davlo laughed bitterly. “Trying to kidnap me, perhaps kill me, a mere diversion for stealing my life’s work?”

“I don’t mean to sound harsh, son, but yes. Exactly that. I grant that you would have a different point of view—but for the rest of the world, right now, your life’s work is of far greater importance than your life. And you’re sure everything is gone? Irretrievably gone?”

“Everything. “

“I see.”

“Governor Kresh? Who did this? Was it the Settlers?”

“Probably,” said Kresh. “But it could have been anyone who wanted to keep the comet from coming down. Right now that doesn’t matter. Right now we have to deal with the situation, not worry about how the situation came to be.”

“That’s not going to be easy, sir. I’ll try.”

There was silence on the line for a moment. “All right, then. Your computer files containing your plans are gone. We have to set to work at once to get them back—or at least get the main part of them back. I’ve seen enough of what the twin control units can do to be sure they could start from the basics of your plan and reconstruct it—probably in greater detail than you had to start with.”

“How very kind of you to say so,” Davlo muttered.

“I meant no offense to your work,” Kresh said. “The control units are designed for this kind of job, and they have the capacity to oversee the climate of an entire planet. Of course they can do more detailed projections than one man working alone, no matter how gifted—especially when that man is working outside his field of expertise. And I might add that no robot or computer or control unit found that comet and saw what it might mean to this planet.”

Davlo sat down in the chair facing the comm unit, folded his arms over his chest, and stared down at the floor. “You’re flattering me,” he said. “Trying to soothe me, make me feel better.”

“Yes, I am,” Kresh agreed, his voice smooth and calm. “Because I need you, and I need you right now. As I was about to say, the control units can reconstruct and refine your plan for targeting the comet—but we need you in your field of expertise.”

“Sir? I don’t understand.”

“Son, we need you to look through your telescope again and relocate that comet. And fast.”

Davlo took a deep breath, shook his head, and kept his gaze fixed on the floor. “Sir, I never found the comet in the first place.”

“What! Are you saying this has all been some kind of hoax? Some kind of fraud?”

“No! No, sir. Nothing like that. I didn’t mean it that way. I meant that the computers found the comet. Automated telescopes found it while doing preprogrammed scans. I’ve never looked through a telescope myself in my life.”

Again, silence on the line, but this time Davlo spoke first. “All the data is gone, sir. Without my computer files, without my written notes, without the log files—there is simply no way at all I can find that comet again in time.”

“But the thing is kilometers across! It’s practically headed straight for the planet right now! How hard could it be to spot?”

Davlo Lentrall let out a tired sigh. The man was right. It shouldn’t be hard at all. How could he explain that it would be all but impossible? “It is extremely hard to spot, sir. It is coming straight for us, and that is part of the problem. Normally we track a comet by spotting its motion against the night sky. Comet Grieg appears to be all but stationary. Not quite motionless, but close. And while it’s a relatively large cometary body, even a big comet is rather small from tens of millions of kilometers away. It also happens to be a rather dark body—and at its present distance, it has a very low apparent magnitude.”

“You’re saying it’s too dim to see? But you saw it before—or at least the computers and the telescopes did.”

“It’s not impossible to see. But it’s very dim and small and far away and with a very small lateral motion. And it’s not just a question of seeing it once. We have to get repeated, accurate measures of its position and trajectory before we can reconstruct the orbit.”

“But what about when it gets closer? Won’t it develop a tail and all the rest of it? Surely that will make it easier to spot.”

“By which time it will be too late. Grieg is a dark-body comet. The comet will be too close, and if it has developed much of a tail, that will mean it is starting to melt. If it gets too warm and melts too much, it will be too fragile to hold together during the course correction. Part of the plan I hadn’t worked out yet was shielding from the sun. I was going to come up with some kind of parasol, a shield to keep the sunlight off.”

“But there’s a chance,” said Kresh. “At least there is some sort of chance we could reacquire the comet if we tried.” There was a brief moment of quiet again before the governor’s voice spoke again. “Here’s what we’re going to do,” he said. “We’re going to keep everything moving forward, based on the assumption that we do reacquire the comet, and that we will decide to go forward with the diversion and the impact. We need to move forward on as many fronts as possible, as fast as possible, and I need some work out of you, right now.

“First I want you to set down the closest approximations you can of the mass, size, position, and trajectory of Comet Grieg. Even rough figures will give us someplace to start in planning for the impact itself. Send that information at once to my data mailbox. Then you are going to get to work at once organizing a search to reacquire Comet Grieg. I will instruct your superiors to give you whatever resources and personnel you need for the job. Tell them as much as you can about the comet. But get that started—and let someone else run it. Because I want you to get to work trying to recover your computer files. Maybe they’re not as lost as we think. There must be something, somewhere—at least enough to give some leads to the team doing the telescope search. Is that clear?”

“Yes, sir. Sir—if I might ask a question?”

“Yes, of course, Dr. Lentrall.”

“I get the impression that you’ve become more convinced that the plan might work.”

“That I have, Dr. Lentrall. I’ve seen and heard quite a bit here about your plan. Enough to make me think we just can’t live without it. Was there anything else?”

“Not at the moment, sir. I’ll be in touch.”

“You certainly will,” the governor replied, with just the slightest hint of humor in his voice. “Kresh out.”

The line went dead.

That should have been his cue to swing into action, but instead, Davlo simply stared at the speaker, expressionless. After what seemed a very long time indeed, he finally stirred himself into action. He set down all he could recall of his comet data, as accurately as possible, knowing full well that the margin of error in most of his figures would render them close to useless. He sent a copy of it off to Kresh’s data mailbox, and another off to the head of the astronomy department, asking for whatever help he could get. Of course, Davlo knew perfectly well that the department head absolutely refused to accept any after-hours calls. She would not get the message until morning. But still, best to have it done.

Simple enough jobs, both of them, but they seemed to take an inordinately long time—and to take a great deal out of Davlo. After the day he had had, there was not really a great deal left to take. When he was at last done with the messages, he did not get up. Instead he sat there, unable to rouse himself. There was a lot more he ought to do, but Davlo Lentrall could not quite bring himself to move. Not quite yet.

It was that hour of the night when rational thought seems most unreasonable, when unreasoning fear seems utterly logical, and disasters seem most probable. Davlo thought of his nameless, faceless, enormously powerful enemies. They were mad enough at him already. He was not entirely sure he wanted to do anything else—like getting out of his chair—that might incur their wrath.

There was some part of Davlo Lentrall that was able to recognize the fragility of his own personality at that moment. A part of him that could see that the game was over. A part of him that knew he had been pretending to be someone and something he was not for a long time. He had seen himself as smarter, braver, better than anyone else. And why not, in a universe where robots protected everyone from the consequences of their actions, where robots did all the hard work and left the posturing for humans? He had always imagined himself as being immune to fear and as impossible to harm. It was easy enough to indulge such fancies when robots warded off all danger.

And that part of Davlo Lentrall could feel it all slipping away. A few more shocks, a few more disasters, and he knew he would not be able to hold together. What was he to do if the mask fell from his face altogether, and the face underneath was blank? He knew now that he was not the person he had pretended to be. But then who was he?

Davlo Lentrall sat in his office chair, still as a switched-off robot, trying to work up the nerve to move.

It might have been a minute later, or an hour later, when Kaelor came into the room. “Come along, sir,” the robot said. “You must rest. There is nothing more you can accomplish tonight.”

Lentrall allowed himself to be led away, allowed Kaelor to peel off his clothes, move him through the refresher, and put him to bed. He was asleep almost before he was fully between the covers. The last thing he saw as his head hit the pillow was Kaelor leaning over him, tucking the sheets up around him.

And the first thing he would think of the next morning was where he might find quite a bit of his lost data.

DONALD 111 WAS every bit as motionless as Lentrall had been, but he was far from inactive. Donald stood in his niche in the wall of Alvar Kresh’s home office, and worked the hyperwave links with all the speed and efficiency that he could muster. To an outside observer, Donald would have appeared completely inert, as if he had been shut down altogether. In point of fact, he was linked into a half-dozen databases, patched through to simultaneous conference calls with robots in the City of Hades maintenance offices, the Department of Public Safety, the Emergency Preparedness Service, the Combined Inferno Police, and a half-dozen other agencies. No one knew for sure what would happen if and when the comet hit, but there were certain basic precautions that could be taken—and Donald could at least get them started.

It had to be anticipated that there would be quakes and aftershocks as a result of the impact, even in Hades, halfway around the planet. That assumption right there meant a great deal of work would have to be done. There were buildings that would have to be braced. Perhaps it would be wise if some old and unneeded buildings were disassembled altogether. Valuable and fragile objects would have to be stored in places of safety.

And then, of course, there were the people. The robots would have to prepare massive places of shelter, where the quakes could be ridden out in safety.

All the computer projections and models made it clear they had to anticipate that the comet impact would inject a large amount of dust, gas, and water vapor into the atmosphere. Theory said the dust injection would be of benefit to the climate in the long run, an aid to the efforts to adjust the planetary greenhouse factor, but it also meant there would be a prolonged period of bad weather. The robots of Inferno had to prepare for this as well.

There were dozens, hundreds, thousands of details to work out, contingencies to prepare for, scarce resources to be allocated between conflicting demands.

Donald had made a status report to the governor three hours after commencing the job, as instructed, although there was not a great deal of new information at that time. Things were really just getting started.

The job his master had given him was enormous in scope, enormous enough that Donald already convinced himself that the job was far beyond his capacity. It was obviously quite impossible for him to organize the entire planet for the comet impact all by himself. But his master, Governor Alvar Kresh, had to know that as well. Clearly, therefore, his orders required some interpretation. Donald would do the best he could for as long as required, but there would come a point where it would be counterproductive for Donald to run things, instead of handing the job to whatever combination of humans and robots were best suited to the job. But until the governor issued orders to that effect, Donald would tackle the job as best he could.

Indeed, the initial stages of the job were well within Donald’s capacities. Later there would be decisions to make that were beyond his scope, but for now he even had a little bit of extra capacity—enough to monitor the news channels, for example. That was a routine part of running a large-scale mobilization job like this one. One had to monitor all the uncontrollable variables that affected the situation. From the operations planning side of things, unfavorable news reports were as much an uncontrollable and unpredictable variable as bad weather or plagues or economic crashes. Nor was it just the news itself that mattered—the way in which was reported was equally important. The mood of the report, the things that were left in and left out, the match-up between the facts as reported and the facts as known to the project team—all of those mattered.

And Donald was enough of a student of human behavior to know that what he heard starting to be reported on the overnight news broadcast was far beyond his ability to judge. All he could know for sure was that it would have some effect, and a complicating one at that.

So he did as any robot would do under the circumstances.

He went looking for a human who could deal with the problem.

FREDDA LEVING OPENED her eyes to see Donald’s calm and expressionless gaze looking down on her. She of all people should not have been unnerved by the sight. After all, she had built Donald, and she knew him as well as anyone else in her life. She knew how solid a protection the Three Laws were, and how utterly reliable Donald was in any event. But even so, it had been a long, hard day, and there was something distinctly unnerving about waking up to see a sky-blue robotic face staring down at one’s self. “Donald,” she said, her voice still heavy with sleep. “What is it?”

“Dr. Leving, I have just monitored an audio channel news report from Inferno Networks concerning the incident today at Government Tower Plaza.”

“That’s hardly surprising,” Fredda said. “What else would they put on the news?”

“True enough, Doctor. However, this report is rather surprising. I believe you should hear it.”

Fredda sighed and sat up in bed. “Very well, Donald. Play it back for me.”

The cool, professional voice of a female newsreader began to speak through Donald’s speaker grille. “Sources close to the investigation have uncovered a rumor that has been circulating for most of the day—that the incident at Government Tower today was actually a coup attempt, an effort to seize control of the government itself.”

Suddenly, Fredda was fully and absolutely awake. What the devil was the woman talking about? There’s hadn’t been any coup attempt.

“Even more remarkable is the reason offered as motivation for the coup attempt,” the newsreader went on. “The attempt was made to prevent the government from causing a comet to crash into the planet. According to the same source, the government is actively and secretly engaged in just such a project, under the belief that the comet impact will somehow enhance the planetary environment. Attempts to contact Governor Kresh for comment have been unsuccessful. We will of course provide further details of this story as they become available.”

The recording ended, and Donald spoke in his own voice. “That was the sum total of reportage on any coup attempt,” Donald said, anticipating Fredda’s first question. “I might add that Inferno Networks has a tradition of sensationalist reports, and that at various times the Settler and Ironhead organizations, as well as the government itself, have found it a useful conduit for leaks.”

“So it could have come from anywhere. When did that broadcast go out?” Fredda asked, trying to think.

“Just a few minutes ago, at 0312 hours local time here in Hades.”

“In the dead of night, the time it would be least likely to have much circulation. Interesting. Very, very interesting. Has anyone from any of the news services attempted to reach Alvar—ah, the governor?”

“Not through any of the access points or comm links that I monitor,” Donald replied.

“In other words, either they didn’t really try to reach him, or they didn’t try very hard,” Fredda said, half to herself. She thought for a moment. “They’re trying to flush us out,” she announced at last. “Get us out in the open, right in their sights. That’s got to be it.”

“I’m afraid I don’t understand,” said Donald. “Who is ‘they’?”

“I would assume that it’s the same people who tried to snatch Davlo Lentrall,” Fredda said. “It means they’re trying to force us to admit there is a plan to drop a comet—and they’re trying to present the idea in the most unfavorable way possible. They want to make it look like the comet idea is so bad that people would risk violence and upheaval rather than let it happen. And if they can make the comet plan seem like some sort of fiendish secret plot, all the better. It will put more pressure on the government—on Alvar—to backpedal, get as far back from the comet idea as possible.”

“I see,” said Donald in a tone of voice that made it clear he did not. “I must admit that the subtleties of human politics are quite beyond me. Might I ask why whoever it was that did this arranged for it to be broadcast at this hour of the night?”

“They’re sending a signal,” Fredda said. “They’re giving us until morning to put together a denial, to explain it away, and let the whole thing evaporate.”

“And if you fail to do so?”

Fredda waved at Donald’s speaker grille, vaguely indicating the recorded human voice that had just come from it. “Then they will use all the news outlets they get can to listen to them. They’ll raise every kind of hell they can. Maybe try to force Alvar out of office.”

“So what do we do?” Donald asked.

Fredda thought for a moment. Logically, the thing to do was call Alvar, consult with him. The trouble was, of course, that she did not know where he was. He had not told her. No doubt she could find him if she wanted to do so. Probably all she had to do was ask Donald. Either he knew, or else he could find out, somehow. But she had the distinct impression that Alvar had wanted to be alone. And Donald had come to her, not to Alvar. That in and of itself strongly implied that Donald did not wish to contact Alvar. Had Alvar left explicit orders with Donald? Or was Donald working on some sort of implied orders? Could she get him to override that instruction with a stated and emphatic command to help her contact her husband? Or suppose he knew where Alvar was but just wanted to protect his master from a politically damaging situation by dumping it in Fredda’s lap?

Damnation! The situation was bad enough without having to go into the whichness of what and the balancing of implied commands and hypothetical First Law issues.

Fredda had gotten to precisely that point in her reasoning when Donald spoke. “I beg your pardon, Dr. Leving, but there is an incoming call for you from the Hades News Reporting Service.”

“For me?” Why the devil would they call her? Unless they had tried for Alvar already. Or else maybe—“Oh, the hell with it,” she said out loud, and stood up. She was too tired for more guessing games. “Audio only. I must look an absolute fright. Put the call through the bedroom comm panel, Donald. And better record the call as well.” She started pacing back and forth, for want of a better outlet for her nervous energy.

“Yes, ma’am,” said Donald. “The caller can hear you—now.”

Thoughtful of Donald to handle it that way. More than a few people had been embarrassed talking to an audio-only caller who wasn’t there—or, worse, by talking indiscreetly before they knew the caller was there. “This is Fredda Leving,” she said to the empty air. “Who is calling, please?”

“Good evening, Dr. Leving.” A very smooth, professional sounding male voice spoke into the empty air. “This is Hilyar Lews, Hades News Reporting.”

Fredda had heard and seen the man on the air, and she did not like him. Besides which, it irritated her that anyone could sound so smooth and polished at this hour of the night. “Did you say, ‘Good evening’?” Fredda asked. “Wouldn’t ‘Good morning’ would be a trifle more accurate, Mr. Lews? And I might add that it is traditional to apologize for calling at this hour,” she said, hoping to put the man off balance.

“Urn, ah, well, yes, ma’am. My apologies.” It was obvious from Lews’s tone of voice that he knew exactly how awkward he sounded. Good.

“Well, now that you have me up, Mr. Lews, did you have a particular reason for calling? Or is this just a friendly chat?” Best to keep the fellow as much off balance as possible.

“Ah, no, ma’am. It’s a very serious call. We’ve been trying to reach the governor concerning the allegations that are being broadcast by Inferno Networks News? Ah—have you heard the I-N News reports?”

“I have indeed,” said Fredda. “And I can speak for my husband without the necessity of disturbing him at this hour. There absolutely, positively, categorically was no coup attempt. There was and is no threat to the government.”

“But what about the—”

“I can’t comment on the details of an ongoing investigation.” Fredda rolled right over whatever Lews was going to ask, glad to have such a convenient phrase to hand.

“Very well, ma’am. But what about this business concerning a comet? Is there any truth at all to that part of the story? It sounds a little too fantastic for it to have been made up out of nothing at all.”

Fredda stopped her pacing back and forth and sat down on the edge of the bed. Why the devil did crises always hit in the middle of the night, when she was half asleep? She had to think, and think fast. It was no good denying the story. Not when it was true, not when it was bound to leak out again, some other way, and soon. But she could not just blandly confirm it either. She had no idea at all how likely the comet plan was. Alvar had gone off somewhere to study the problem. Suppose he had already concluded the idea was, after all, as insane as it sounded? She could not commit him, either way. But she couldn’t let it go with a flat “no comment” either. That would simply start the rumor mill churning faster than ever.

In short, there was nothing she could say that wouldn’t cause some serious damage. She should never have taken this call in the first place. But it was too late now. She had to say something. She took a deep breath, and spoke slowly, carefully. “There is a comet,” she said. “The governor is aware of… studies that have been made concerning the comet.” Suddenly Fredda had an inspiration. Something she could say that was utterly truthful, and yet something that was completely misleading. Something that might slow down the rumor long enough to buy them some time. “I do not know all the details, but I believe the project has something to do with Operation Snowball. I assume you are familiar with snowball?”

“Ah, yes, somewhat, ma’am.” There was a longish pause. At a guess, Lews was doing a lookup on “snowball” in some sort of reference system. Fredda smiled. It was increasingly obvious to her that Lews was not quite as smooth and prepared as he let on. That was also good. “It’s a project to mine ice from comets and drop it into the atmosphere,” Lews said, in a tone of voice that made it obvious that he was reading the words from off some screen or another.

“Precisely. In effect, dropping a comet on the planet—a few kilograms at a time. Snowball has been going on for some time, and it is the only officially approved project concerning comets that I know about.” The statement was true, if misleading in the extreme. The Comet Grieg plan was not, after all, approved. “I trust that answers your questions, Mr. Lews?”

“Well, I suppose so,” Lews replied.

Suppose what you will, thought Fredda, just so long as I’ve muddled the trail enough to hold you off. “In that case, I’ll be getting back to bed. Good night—or good morning—Mr. Lews.” Fredda made a throat-cutting gesture to Donald, and he cut the connection. “I hope I did that right,” she said, more to herself than to Donald. “See to it that a copy of the original broadcast, and a copy of that conversation, are in the governor’s data mailbox. When he does check in, he’ll need to know what’s going on.”

“I have already put copies into his mailbox, Doctor.”

“Excellent.” Fredda slumped backward onto the bed, her feet still dangling down over the front of the mattress. That wouldn’t do. No point dozing off like that when she could so easily crawl back beneath the covers. She stood up, went around the bed, and got back into it, wondering if there was indeed any point in getting comfortable. It wouldn’t surprise her if she were unable to sleep at all. She certainly had enough things to worry about for her to keep her staring at the ceiling for the rest of the night. Where was Alvar? What was he going to do about the comet? Had she done it right, or had she just made a bad mess worse? No way to know. No way to know until it was too late.

It seemed her to that was the running theme for everything that had happened in the last few days. She yawned, shut her eyes, rolled over on her side, and set forth on a valiant effort to fall asleep.

FREDDA OPENED HER eyes again, to Donald staring down at her once more.

“Your pardon, Dr. Leving, but there is an urgent call for you. The pseudo-robot Caliban says he must speak with you at once.”

Fredda sighed. She knew she had to take the call, and that Caliban would only call if it were important. But even so, it was turning into a very long night. “Now what time is it?” she asked.

“It is now 0429 hours,” Donald said.

“It would be,” she muttered. “All right, on the bedroom comm again. Audio only.” Perhaps she shouldn’t have cared how she looked to a robot, but she did.

“Very well, Dr. Leving. Caliban can hear you—now.”

“Caliban, hello,” Fredda said, struggling not to yawn. “What’s going on?”

“Dr. Leving, please forgive me for disturbing you at this hour, but I felt that we must talk. Prospero and I are leaving the city now, headed for Depot and beyond. We have learned through our own sources what is likely to befall our city.”

Fredda blinked in surprise. She had always known that Caliban and the New Law robots had good sources of information, but she had not known they were that good. And then there was the way Caliban had phrased it. “Befall” the New Law city. A subtle pun that would reveal very little to anyone who did not know what was going on. It told her Caliban was being cautious—and that he wanted her to be equally cautious. Was he worried about eavesdroppers, or snooper robots with orders to listen for certain words? Or was he just assuming that Alvar was still there, and might be able to overhear? “I think you are being wise,” she said. “Events are moving quite rapidly, and I don’t think they will be easy to control.”

“I quite agree,” said Caliban. “We must set to work at once preparing our citizens for the contingency in question. We may well need to call on our friends for help.”

“You can certainly call on me,” said Fredda. “Whatever I can do, I will.” She hesitated for a moment. That was a rather sweeping promise, after all. It seemed likely that all of the Utopia region would have to be evacuated, and that would put a huge strain on transport and other resources. Few people were likely to worry about the New Law robots getting their fair share of the help. “But there will probably be limits—severe limits—on what I can do.”

“I understand that,” said Caliban. “We have always been on our own. But even marginal assistance could turn out to be vitally important.”

Fredda felt a pang of guilt. It was bad enough when you could do very little for your own creations. It was worse when they expected even less. “Contact me when you get there,” she said. “Let me know whatever you need, and I’ll do my damnedest to get it.”

There was a moment’s silence on the line. “What we need,” said Caliban, “is a place where we can be left alone. We thought we had that, up until now. Caliban out.”

The line went dead, and Fredda cursed to herself, fluently, violently, and at length. It wasn’t supposed to be like this. She had never asked for, never considered, the burden of obligation she had put on herself when she had created the New Law robots. She had never felt that she owed a debt, a creator’s debt to the Three-Law robots she had built. But with Caliban, with the New Law robots, she felt she owed them something, simply by virtue of calling them into existence.

Perhaps that was the difference between creating a race of willing slaves, and a race of beings who wanted to be free.

Fredda slumped back in bed. Damnation. Now she’d never get to sleep.

THE FIRST HINTS of dawn were a whisper in the eastern skies of Hades as Caliban, Prospero, and Fiyle rode Prospero’s aircar up out of the city’s tunnel system. Fiyle was clearly exhausted, yawning uncontrollably. He had been up all night, Prospero grilling him relentlessly for any tiny scrap of information he might have concerning the comet operation.

Caliban looked at the man with something very close to sympathy. Perhaps Fiyle was little better than a turncoat who sold himself to all and sundry, but even so, there was some whiff of honor about the man. Something in him had put limits on his petty betrayals and the buying and selling of trust. Something had put survival of the New Law robots above the lure of Trader Demand Notes. There was something to respect, even in this contemptible man.

And it was, after all, that impulse to decency that had placed Norlan Fiyle in danger. That meant Norlan Fiyle had best get out of town, and fast. And the two robots, needless to say, had their own reasons to travel. They needed to warn Valhalla.

Caliban looked from Fiyle to Prospero, and then at the city itself. He bid a farewell—and not an entirely fond one—to Hades. Perhaps he would someday return to the city. But events were moving too quickly, things were happening too fast. Somehow, a part of him knew that the city he saw now, here, today, would soon be changed beyond recognition, even if the buildings and the streets remained the same. For the lives of the people would be changed utterly, and the world beyond the city made anew.

Unless, of course, city, people, and world were all simply smashed flat instead. Utter destruction was one form of change.

The aircar reached for sky, and headed into the dawn.

ALVAR KRESH SWITCHED off the link to his data mailbox, surprised at his own sense of relief. He sat at the console in front of Dum and Dee, where, it seemed to him, he had spent several years, instead of merely most of a night and most of a morning, and tried to consider the situation. The day shift for the Terraforming Center had been filtering in for the last half an hour or so, all of them more than a trifle surprised to find Governor Alvar Kresh in possession. Kresh paid them as little mind, and as little attention, as possible. Dr. Soggdon was still at the center as well, for reasons Kresh did not entirely understand. Perhaps a sense of duty was keeping her there to protect Unit Dee’s honor against the interloper. If that was the case, she was not at her most effective. She was at her desk, head pillowed on her folded arms, fast asleep.

Kresh turned his attention back to the news he had just received. The people trying to wreck the comet-capture project did not know it, but they had done him a very large favor indeed. Kresh had been dreading the necessity of informing the world at large of the comet project. Sooner or later, Inferno would have to know, but he had enough on his hands without being forced to calm the inevitable public uproar at the same time.

By leaking the information, the opposition had relieved Kresh of the necessity of going before the cameras and the reporters. And Fredda had struck precisely the right note, deflating the uproar without actually discounting the story. Thank Space he hadn’t been home to receive that call himself.

When he had succeeded to the governorship, Kresh had made a point of eliminating all the layers of press secretaries and communications offices and scheduled appointments and all the other tricks of the trade meant to keep reporters well away from the governor, allowing the news people all but unlimited access to him. There had been plenty of times when he had regretted that policy, and today he thanked whatever source of luck he had that he had managed to avoid the press today. It might not be a bad idea to stay right where he was, keeping a nice, low profile for a while, with as little direct communication with the outside world as possible. Here he could focus on the project itself. If he went back to Hades, it was all but inevitable that he would get swept up talking about the project, rather than doing something about it.

Very well. Now the world knew about the comet, and he had not been the one to tell them. All to the good. But now there was another problem. The obvious thing to do now was to allow the public discussion move forward to the point where he could confirm the existence of the comet plan to a populace ready to accept the idea. But how the devil could he do that when he would be forced to make the ridiculous-sounding admission that they had misplaced the comet?

Plainly, the best answer to that problem was to relocate the comet as soon as possible. But Kresh had done as much as he could in that direction for the moment. Sometimes the job of leadership was simply to get things started, and trust in others to get them done. He would have to keep on here, focusing on other aspects of the project, working on the assumption that they would be able to find the comet in time. Back to work, he told himself.

“Still with me, Dee?” Kresh asked.

“Yes, sir, I am,” Unit Dee replied. “Was there anything of interest in your mailbox?”

“Quite a bit,” he said. “But nothing that you need worry about. I have a new task for you.”

“I would be delighted to be of further assistance.”

“Right,” said Kresh, his tone of voice deliberately brusque. There was something about courtly manners from a robot that got on his nerves. “My personal robot, Donald 111, is at work on the preliminary preparations for the cometary impact. Safety plans, evacuations plans, that sort of thing. I want to contact him and have him hand off that job to you. Clearly, you’re better suited to it than he is. I should have assigned the job to you in the first place. Relay my orders to that effect, then order Donald to join me here as soon as possible without revealing my whereabouts.”

“I will contact him at once,” Dee said.

“Good,” said Kresh. “I’m going to step out for a breath of fresh air. When I return, we will return to refining your impact targeting plan.”

“With the extremely rough data we got from Dr. Lentrall, I am not sure there is more we can do.”

“But there might be,” Kresh said. “At the very least we can work out a range of scenarios and contingencies, so that we are more ready to act when the time comes. We’ll work out a few hundred possible rough trajectories, and give Unit Dum something to do.”

Dee did not respond to the very small joke, but instead spoke with her usual urbane civility. “Very well, sir. I will continue with my other duties while I await your return.”

“Back in a minute,” Kresh said, and stood up. He stretched, yawned, and ignored the stares of the Center’s workers as he rubbed his tired face. Let them wonder what their governor was doing here. Alvar headed out the huge armored door of Room 103, down the corridor of the Terraforming Center, out the double doors that led to the outside, and into the morning.

It had been a long time since he had worked a job all night, worked all the clock around. He was close to exhausted, but not quite. There was something invigorating about seeing the morning after a hard night’s work. Somehow Kresh always felt as if he had earned the loveliness of morning after working through the darkness.

The rains were gone now, and the world was fresh and bright, scrubbed clean. The sky was a brilliant blue, dotted with perfect white clouds that set off the deep azure of the heavens. The air smelled sweet, and good. Alvar Kresh looked toward the west, in the direction of the governor’s Winter Residence. He remembered another morning like this, with everything fresh and bright, and all good things possible. A morning he had spent with Fredda, just after he had assumed the governorship. That had been a morning of good omen. Perhaps this would be as well.

And maybe it was time to move over to the Winter Residence. That would let him stay on the island. The more he thought about it, the more it seemed a good idea to keep a low profile just now. But that could wait until later. Right now there was something else he could do to keep himself isolated. He walked over to his aircar, sitting in the middle of a parking lot that was now half full of aircars. Oberon saw him through the cockpit viewport, and the door of the craft swung open as he approached. Kresh went aboard, and found Oberon just coming aft to meet him.

“Are we heading home, sir?” Oberon asked in his slow, ponderous voice.

“You are, but I’m not. Fly the aircar back and give my regards to my wife. Tell her I heard the recordings, and that she handled them exactly right. Tell her where I am, and that if she wishes, she can join me here—if she can do so undetected. I would value her advice. You must make it clear I wish to keep my whereabouts as private as possible for the time being. I need time to think, and work, without the world jiggling my elbow.”

“What of the workers here, sir?” asked Oberon. “They know where you are.”

“True enough, and sooner or later something is going to leak. With luck it will be later. Just see to it you aren’t the one that does the leaking. Fly an evasive pattern so it looks like you’re coming in to Hades from someplace besides here.”

“Very good, sir. Unless there is something further, I will leave at once.”

“Nothing else,” said Kresh. “Go.” He turned and stepped out of the hatch, and moved back toward the building to get clear for Oberon’s takeoff. After a moment or two the aircar launched, moving smoothly and slowly up into the sky. Kresh was on his own—or at least he could pretend he was. He was, after all, the governor. He could call on any sort of transport or communication he liked, whenever he liked. But without the aircar there, he was just that little bit more cut off, that little bit more isolated.

He had a little time.

Now if only he had the trajectory and coordinates for the comet, maybe things would turn out all right after all.

Maybe.

DAVLO LENTRALL’S EYES snapped open. He sat bolt upright in bed. He had gone from stone cold asleep to quiveringly awake and alert in the flicker of a heartbeat. He knew. He knew. But he would have to proceed carefully. Very carefully indeed, or it would all be lost, all be over. He forced himself to think it through, work out all the logical consequences in his head. There was only going to be one chance to do this thing, and it was clear the odds were against him. He was going to have to move carefully, and act as normally as possible. Davlo knew he could not give his quarry any reason at all to suspect him.

Well, if he were going to have to act normally, there was no time like the present to start. He pushed the button by his bedside, and, after the briefest of delays, Kaelor came in. “Good morning,” the robot said. “I hope you slept well.”

“Very well indeed,” said Davlo in what he hoped was a light and casual tone of voice. “I certainly needed it after yesterday.”

“One or two things did go on,” Kaelor said, the familiar sardonic tone in his voice.

“It wasn’t an easy day for you, either,” said Davlo. “And I never did get to thank you for all you did. “

“I couldn’t help but do it, sir, as you know perfectly well.”

“Yes,” said Davlo. “But even so, I want you to know it is appreciated.” He got out of bed, and Kaelor produced his robe and slippers from the closet. Davlo shrugged the robe on over his shoulders and knotted the tie loosely in front of him, then stepped into the slippers. He yawned strenuously and walked out of the bedroom, Kaelor following and shutting the door behind him.

Davlo had long ago decided that breakfast was a meal best consumed in the most soothing surroundings and circumstances possible. Therefore, contrary to the custom in most Infernal households, he did not bathe or dress before going down to breakfast, but instead ate in his pajamas and robe. On the same principle of informal comfort, his breakfast room was large, cool and shady, with the table facing large bay windows that looked out over a meticulously well-kept garden. There were two robots at work pruning the shrubbery, and a third on its knees by one of the flower beds, apparently doing some sort of work by the roots. Most mornings Davlo enjoyed watching the garden robots at their tasks, and used the time to decide what else needed doing about the place, but this morning he hardly paid the yardwork any notice at all.

But then he reminded himself it was important, above all things, to act normal, to do all the things he would normally do. He sat down at the table in his usual chair facing the window, and watched carefully as the robots trimmed back the hedges. “Make sure the garden staff checks carefully for storm damage, and clears out any storm debris,” Davlo said. “That was a devil of a rain last night.”

“So it was,” Kaelor responded as he put down the tray and served breakfast to his master. “I have already seen to it that the outdoor staff will attend to the matter.”

“Very good,” said Davlo, and yawned. “Mmmph. Still a little sleepy. I might need an extra cup of tea to wake up this morning,” he said. Could he really bring himself to act against the robot who had saved his life the day before? He thought back to the day before, and the way he had fallen apart in the face of danger and disaster. He shook his head. No. Not today. He would show the world he could take action, and act decisively. He was on the verge of congratulating himself on his newfound courage when he reminded himself that there was not much risk involved when one attacked a Three-Law robot.

“I’ll bring the tea at once, sir,” Kaelor said, “assuming you really want it.”

“Hold off on it just a bit,” Davlo said. Was it his imagination, or was Kaelor a bit overalert, oversolicitous? For the average robot, his behavior this morning would have been borderline rude, but for Kaelor it was sweetness and light.

“Very well,” said Kaelor, in a tone of voice that made it clear what he thought of Davlo’s indecisiveness. In a strange way, that made Davlo feel better. After all, Kaelor was normally rather curt. Or was Kaelor just “acting” normal, in the same way Davlo himself was? Davlo did not dare ask. Better just to eat his breakfast and wait for his moment. He turned to his food and did his best to notice what it was he was eating. After all, Davlo Lentrall was a man who normally enjoyed his food.

His chance came as Kaelor was clearing away the last of the breakfast dishes, and Davlo had pushed back his chair from the table. Struggling between the need to be on the alert and the need to seem at ease, Davlo nearly missed the opportunity. But when Kaelor reached across the table to collect the last glass, just as Davlo was standing up, the robot had to turn his back completely on his master.

The golden moment lay open to Davlo, and he moved with a smooth and focused speed. He flipped open the door over the compartment on Kaelor’s back, and revealed the robot’s main power switch underneath. Kaelor was already turning to react, to get away, when Davlo threw the switch down.

His power cut, overbalanced as he leaned over the table, Kaelor fell like a stone, dropping the dishes he held and crashing into the wooden tabletop with enough force to break it in two. Davlo moved back a step or two, hating himself for what he had just done to the robot, the sentient being who had saved his life the day before. But it was necessary. Absolutely necessary. He felt anything but heroic.

He turned his back on the collapsed robot and the debris of the ruined table, and went to the comm center. There was a chance, at least a chance, that he could extract the knowledge he needed. The knowledge that might well save Inferno. It was just barely possible that he had saved the world by turning off a robot. There was a lot to think about in that idea, but there was no time for it now. He had to call Fredda Leving.

If anyone could get the information out of Kaelor, she could.

FREDDA LEVING WATCHED as her four service robots unpacked and set up the portable robot maintenance frame in the middle of Davlo Lentrall’s living room. Once it was assembled, they lifted Kaelor’s still-inert form up onto it and attached it firmly to the frame with the use of hold-down straps.

The maintenance frame itself was attached to its base by a complex arrangement of three sets of rotating bearings, built at right angles to each other, so that the frame could be spun around into any conceivable orientation. Thus, a robot clamped into the frame could be spun and swiveled and rotated into whatever position was most convenient to the roboticist doing the work. Once the service robots had Kaelor up on the frame, Fredda stepped in and went to work. Not that she had much hope of success, but with the stakes this high, one had to at least try.

She swiveled Kaelor’s body around until he was lying facedown, his unpowered eyes staring blankly at the floor. She found Kaelor’s standard diagnostic port at the base of his neck and plugged in her test meter. She switched from one setting to another, watching the display on the meter. “No surprises there,” she said. “The standard diagnostics show that his basic circuits are all functioning normally, but we knew that.”

“Can you tap into his memory system through that port?” Davlo asked, leaning in a bit closer than Fredda would have preferred. He was nervous, agitated, his face gaunt and pale. He kept rubbing his hands together, over and over.

“I’m afraid not,” said Fredda, trying to assume a cool, professional tone. “It’s not that easy. This just shows me the basic systems status. Even though he’s powered down, there are still lots of circuits with trickle-charges running through them, things that need power to maintain system integrity. This just shows me he hasn’t blown a fuse, that his basic pathing is stable. Now I know we’re not going to harm him accidentally as we proceed.” Whether or not we decide to harm him deliberately is quite another story, she thought. No sense saying any such thing out loud. Lentrall was in a bad enough state as it was.

Fredda left the test meter plugged in and hung it off a utility hook on the side of the maintenance frame. She got in a little closer, adjusted the position of the table slightly, and undid the four clampdown fasteners that held on the back of Kaelor’s head, and carefully lifted the backplate off. She took one look at the circuitry and cabling thus revealed and shook her head. “No,” she said. “I was afraid of that. I’ve seen this setup before.” She pointed to a featureless black ball, about twelve centimeters across. “His positronic brain is in that fully sealed unit. The only link between it and the outside world is that armored cable coming out of its base, where the spinal column would be on a human. That cable will have about five thousand microcables inside, every one of them about the diameter of a human hair. I’d have to guess right on which two of those to link into, and get it right on the first try, or else I would quite literally fry his brain. Short him out. Space alone knows how long it would take to trace the linkages. A week probably. The whole brain assembly is designed to be totally inaccessible.”

“But why?” asked Davlo Lentrall.

Fredda smiled sadly. “To protect the confidential information inside his head. To keep people from doing exactly what we’re trying to do—get information out of him that he would not want to reveal.”

“Damnation! I’d thought we’d just be able to tap into his memory system and extract what we needed.”

“With some robots that might be possible—though incredibly time-consuming,” Fredda said as she reattached the back of Kaelor’s head. “Not with this model.”

“So there’s nothing we can do,” Lentrall said. “I mean, on the level of electronics and memory dumps.” As he spoke, his face was drawn and expressionless, and he seemed unwilling to meet Fredda’s gaze, or to look at Kaelor. He was the portrait of a man who had already decided he had to do something he was not going to be proud of. And the portrait of a man who was going to crack before very much longer.

“Nothing much,” said Fredda.

“So we’re going to have to talk to him—and we know he doesn’t want to talk.”

Fredda wanted to have some reason to disagree, but she knew better. Kaelor would already have spoken up if he had been willing to speak. “No, he doesn’t,” she said. She thought for a moment and picked up her test meter. “The two things I can do is deactivate his main motor control, so he can only move his head and eyes and talk. And I can set his pseudoclock-speed lower.”

“Why cut his main motor function?” Davlo asked.

So he won’t tear his own head off or smash his own brain in to keep us from learning what he wants kept secret, Fredda thought, but she knew better than to tell that to Davlo. Fortunately, it didn’t take her long to think of something else. “To keep him from breaking out and escaping,” she said. “He might try to run away rather than speak to us.”

Davlo nodded, a bit too eagerly, as if he knew better but wanted to believe. “What about the clock speed?” he asked.

“In effect, it will make him think more slowly, cut his reaction time down. But even at its minimum speed settings, his brain works faster than ours. He’ll still have the advantage over us—it’ll just be cut down a bit.”

Davlo nodded. “Do it,” he said. “And then let’s talk to him.”

“Right,” said Fredda, trying to sound brisk and efficient. She used the test meter to send the proper commands through Kaelor’s diagnostic system, then hooked the meter back on to the maintenance frame. She spun the frame around until Kaelor was suspended in an upright position, eyes straight ahead, feet dangling a half meter off the floor. He stared straight ahead, his body motionless, his eyes sightless. The test meter cable still hung from his neck, and the meter’s display showed a series of diagnostic numbers, one after the other, in blinking red.

Seeing Kaelor strapped in that way, Fredda was irresistibly reminded of an ancient drawing she had seen somewhere, of a torture victim strapped down on a frame or rack not unlike the one that held Kaelor now. That’s the way it works, she thought. Strap them down, mistreat them, try and force the information out of them before they die. It was a succinct description of the torturer’s trade. She had never thought before that it might apply to a roboticist as well. “I bet you don’t like this any better than I do,” she said, staring at the robot. She was not sure if she was talking to Kaelor or Davlo.

Now Davlo looked on Kaelor, and could not take his eyes off him. “Yesterday, he grabbed me and stuffed me under a bench and used his body to shield mine. He risked his life for mine. He’d remind me himself that the Three Laws compelled him to do it, but that doesn’t matter. He risked his life for mine. And now we’re simply going to risk his life.” He paused a moment, and then said it in plainer words. “We’re probably about to kill him,” he said in a flat, angry voice. “Kill him because he wants to protect us—all of us—from me.”

Fredda glanced at Davlo, and then looked back at Kaelor. “I think you’d better let me do the talking,” she said.

For a moment she thought he was about to protest, insist that a man ought to be willing to do this sort of job for himself. But instead his shrugged, and let out a small sigh. “You’re the roboticist,” he said, still staring straight at Kaelor’s dead eyes. “You know robopsychology.”

And there are times I wished I knew more human psychology, Fredda thought, giving Davlo Lentrall a sidelong glance. “Before we begin,” she said, “there’s something you need to understand. I know that you ordered Kaelor built to your own specifications. You wanted a Constricted First Law robot, right?”

“Right,” said Lentrall, clearly not paying a great deal of attention.

“Well, you didn’t get one,” Fredda said. “At least not in the sense you might think. And that’s what set up the trap you’re in now. Kaelor was designed to be able to distinguish hypothetical danger or theoretical danger from the real thing. Though most high-function robots built on Inferno are capable of distinguishing between real and hypothetical danger to humans, they in effect choose not to do so. In a sense, they let their imaginations run away with them, worry that the hypothetical might become real, and fret over what would happen in such a case, and treat it as if were real, just to be on the safe side of the First Law. Kaelor was, in effect, built without much imagination—or what passes for imagination in a robot. He is not capable of making that leap, of asking, ‘What if the hypothetical became real?’ ”

“I understand all that,” Davlo said irritably.

“But I don’t think you understand the next part,” Fredda said with more coolness than she felt. “With a robot like Kaelor, when the hypothetical, the imaginary, suddenly does become real, when it dawns on such a robot that it has been working on a project that is real, that poses real risks to real people—well, the impact is enormous. I would compare it to the feeling you might have if you suddenly discovered, long after the fact, that, unbeknownst to yourself, some minor, even trifling thing you had done turned out to cause the death of a close relative. Imagine how hard that would hit you, and you’ll have some understanding of how things felt to Kaelor.”

Davlo frowned and nodded. “I see your point,” he said. “And I suppose that would induce a heightened First Law imperative?”

“Exactly,” Fredda said. “My guess is that, by the time you switched him off, Kaelor’s mental state was approaching a state of First Law hypersensitivity, rendering him excessively alert to any possible danger to humans. Suddenly realizing that he had unwittingly violated First Law already would only make it worse. Once we switch Kaelor back on, he’s going to revert to that state instantly.”

“You’re saying he’s going to be paranoid,” Davlo said.

“It won’t be that extreme,” said Fredda. “He’ll be very careful. And so should we be. Just because his body is immobilized, it doesn’t mean that he won’t be capable of committing—of doing something rash.”

Davlo nodded grimly. “I figured that much,” he said.

“Are you ready, then?”

He did not answer at first. He managed to tear his eyes away from Kaelor. He paced back and forth a time or two, rubbed the back of his neck in an agitated manner, and then stopped, quite abruptly. “Yes,” he said at last, his eyes locked on the most distant corner of the room.

“Very well,” she said. Fredda pulled an audio recorder out of her tool pouch, switched it on, and set on the floor in front of Kaelor. If they got what they needed, she wanted to be sure they had a record of it.

She stepped around to the rear of the maintenance frame, opened the access panel, and switched Kaelor back on. She moved back around to the front of the maintenance frame, and positioned herself about a meter and a half in front of it.

Kaelor’s eyes glowed dimly for a moment before they flared to full life. His head swiveled back and forth, as he looked around himself. He looked down at his arms and legs, as if confirming what he no doubt knew already—that his body had been immobilized. Then he looked around the room, and spotted Lentrall. “It would appear that you figured it out,” Kaelor said. “I was hoping for all our sakes that you would not.”

“I’m sorry, Kaelor, but I—”

“Dr. Lentrall, please. Let me handle this,” said Fredda, deliberately speaking in a cold, sharp-edged, professional tone. This had to be impersonal, detached, dispassionate if it was going to work. She turned to Kaelor, up there on the frame. No, call the thing by its proper name, even if she had just now realized what that name was. The rack. The torturer’s rack. He hung there, paralyzed, strapped down, pinned down, an insect in a collector’s sample box, his voice and his expressionless face seeming solemn, even a little sad. There was no sign of fear. It would seem Kaelor had either too little imagination, or too much courage, for that.

Suddenly she felt a little sick, but she forced herself to keep all hint of that out of her voice and expression. She told herself she was imposing human attributes on Kaelor, investing him with characteristics and emotions he simply did not have. There was no practical difference between having him up on that rack and having a malfunctioning aircar up on a hydraulic lift in a repair shop. She told herself all of that, and more, but she did not believe a word of it. She forced herself to look steadily, coolly, at Kaelor, and she addressed him. “Kaelor, do you know who I am?”

“Yes, of course. You are Dr. Fredda Leving, the roboticist.”

“Quite right. Now then, I am going to give you an order. You are to answer all my questions, and answer them as briefly as possible. Do not provide any information I do not ask for, or volunteer any information. Regard each question by itself. The questions will not be related to each other. Do you understand?” she asked.

“Certainly,” said Kaelor.

“Good.” Fredda was hoping, without much confidence, that she would be able to ask her questions in small enough pieces that no one question would present a First Law violation. And of course the questions would be related—that part was a baldfaced lie. But it might be a convincing enough lie to help Kaelor live through this. She knew for certain that asking, straight-out, the one big question to which they needed an answer would be absolutely catastrophic. She dared not ask for the big picture. She could only hope Kaelor would be willing and able to provide enough tiny pieces of the puzzle.

The trouble was, Kaelor had to know what she was doing as well as she did. How far would he be able to go before First Law imperative overrode the Second Law compulsion to obey orders?

There was one last thing she could do to help Kaelor. Fredda did not have any realistic hope that the Third Law’s requirement for self-preservation would help sustain Kaelor, but she could do her best to reinforce it all the same. “It is also vital for you to remember that you are important as well. Dr. Lentrall needs you, and he very much wants you to continue in his employ. Isn’t that so, Doctor?”

Lentrall looked up from the hole he was staring at in the floor, and glanced at Fredda before settling his gaze on Kaelor. “Absolutely,” he said. “I need you very much, Kaelor.”

“Thank you for saying so,” Kaelor said. He turned his gaze back on Fredda. “I am ready for your questions,” he said.

“Good,” said Fredda. It might well help Kaelor if she kept the questions as disordered as possible, and tossed in a few unrelated ones now and then. “You work for Dr. Lentrall, don’t you?” she asked.

“Yes,” said Kaelor.

“How long have you been in his employ?”

“One standard year and forty-two days.”

“What are the specifications for your on-board memory system?

“A capacity of one hundred standard years non-erasable total recall for all I have seen and heard and learned.”

“Do you enjoy your work?”

“No,” said Kaelor. “Not for the most part.”

An unusual answer for a robot. Generally a robot, when given the chance, would wax lyrical over the joys of whatever task it was performing.

“Why do you not enjoy your work?” Fredda asked.

“Dr. Lentrall is often abrupt and rude. He will often ask for my opinion and then reject it. Furthermore, much of my work in recent days has involved simulations of events that would endanger humans.”

Uh-oh, thought Fredda. Clearly it was a mistake to ask that follow-up question. She would have to reinforce his knowledge of the lack of danger, and then change the subject, fast, before he could pursue that line of thought. Thank Space she had turned down his pseudo-clock-rate. “Simulations involve no actual danger to humans,” she said. “They are imaginary, and have no relation to actual events. Why did you grab Dr. Lentrall and force him under a bench yesterday?”

“I received a hyperwave message that he was in danger. First Law required me to protect him, so I did.”

“And you did it well,” Fredda said. She was trying to establish the point that his First Law imperatives were working well. In a real-life, nonsimulated situation, he had done the proper thing. “What is the status of your various systems, offered in summary form?”

“My positronic brain is functioning within nominal parameters, though near the acceptable limit for First Law-Second Law conflict. All visual and audio sensors and communications systems are functioning at specification. All processing and memory systems are functioning at specification. A Leving Labs model 2312 Robotic Test Meter is jacked into me and running constant baseline diagnostics. All motion and sensation below my neck, along with all hyperwave communication, have been cut off by the test meter, and I am incapable of motion or action other than speech, sight, thought, and motion of my head.”

“Other than the functions currently deactivated by the test meter, deliberate deactivations, and normal maintenance checks, have you always operated at specification?”

“Yes,” said Kaelor. “I remember everything.”

Fredda held back from the impulse to curse out loud, and forced herself to keep her professional demeanor. He had violated her order not to volunteer information, and had volunteered it in regard to the one area they cared about. Only a First Law imperative could have caused him to do such a thing. He knew exactly what they were after, and he was telling them, as best he could under the restrictions she had placed on him, that he had it.

Which meant he was not going to let them have it. They had lost. Fredda decided to abandon her super-cautious approach, and move more quickly toward what they needed.

“Do you remember the various simulations Dr. Lentrall performed, and the data upon which they were based?”

“Yes,” Kaelor said again. “I remember everything.”

A whole series of questions she dared not ask flickered through her mind, along with the answers she dared not hear from Kaelor. Like a chess player who could see checkmate eight moves ahead, she knew how the questions and answers would go, almost word for word.

Q: If you remember everything, you recall all the figures and information you saw in connection with your work with Dr. Lentrall. Why didn’t you act to replace as many of the lost datapoints as possible last night when Dr. Lentrall discovered his files were gone? Great harm would be done to his work and career if all those data were lost for all time.

A: Because doing so would remind Dr. Lentrall that I witnessed all his simulations of the Comet Grieg operation and that I therefore remembered the comet’s positional data. I could not provide that information, as it would make the comet intercept and retargeting possible, endangering many humans. That outweighed the possible harm to one man’s career.

Q: But the comet impact would enhance the planetary environment, benefiting many more humans in the future, and allowing them to live longer and better lives. Why did you not act to do good to those future generations?

A: I did not act for two reasons. First, I was specifically designed with a reduced capacity for judging the Three-Law consequences of hypothetical circumstances. I am incapable of considering the future and hypothetical well-being of human beings decades or centuries from now, most of whom do not yet exist. Second, the second clause of the First Law merely requires me to prevent injury to humans. It does not require me to perform any acts in order to benefit humans, though I can perform such acts if I choose. I am merely compelled to prevent harm to humans. Action compelled by First Law supersedes any impulse toward voluntary action.

Q. But many humans now alive are likely to die young, and die most unpleasantly, if we do no repair the climate. By preventing the comet impact, there is a high probability you are condemning those very real people to premature death. Where is the comet? I order you to tell me its coordinates, mass, and trajectory.

A. I cannot tell you. I must tell you. I cannot tell you—

And so on, unto death.

It would have gone on that way, if it had lasted even that long. Either the massive conflict between First and Second Law compulsions would have burned out his brain, or else Kaelor would have invoked the second clause of First Law. He could not, through inaction, allow harm to humans.

Merely by staying alive, with the unerasable information of where the comet was in his head, he represented a danger to humans. As long as he stayed alive, there was, in theory, a way to get past the confidentiality features of Kaelor’s brain assembly. There was no way Fredda could do it here, now, but in her own lab, with all her equipment, and with perhaps a week’s time, she could probably defeat the safeties and tap into everything he knew.

And Kaelor knew that, or at least he had to assume it was the case. In order to prevent harm to humans, Kaelor would have to will his own brain to disorganize, disassociate, lose its positronic pathing.

He would have to will himself to die.

That line of questioning would kill him, either through Law-Conflict burnout or compelled suicide. He was still perilously close to both deaths as it was. Maybe it was time to take some of the pressure off. She could reduce at least some of the stress produced by Second Law. “I release you from the prohibition against volunteering information and opinions. You may say whatever you wish.”

“I spent all of last night using my hyperwave link to tie into the data network and rebuild as many of Dr. Lentrall’s work files as possible, using my memories of various operations and interfaces with the computers to restore as much as I could while remaining in accordance with the Three Laws. I would estimate that I was able to restore approximately sixty percent of the results-level data, and perhaps twenty percent of the raw data.”

“Thank you,” said Lentrall. “That was most generous of you.”

“It was my duty, Dr. Lentrall. First Law prevented me from abstaining from an action that could prevent harm to a human.”

“Whether or not you had to do it, you did it,” said Lentrall. “Thank you.”

There was a moment’s silence, and Kaelor looked from Lentrall to Fredda and back again. “There is no need for these games,” he said. “I know what you want, and you know thhhat I I I knowww.”

Lentrall and Fredda exchanged a look, and it was plain Lentrall knew as well as she did that it was First Law conflict making it hard for Kaelor to speak.

Kaelor faced a moral conundrum few humans could have dealt with well. How to decide between probable harm and death to an unknown number of persons; and the misery and the lives ruined by the ruined planetary climate. And it is my husband who must decide, Fredda told herself, the realization a sharp stab of pain. If we succeed here, I am presenting him with that nightmare choice. She thrust that line of thought to one side. She had to concentrate on Kaelor, and the precious knowledge hidden inside him. Fredda could see hope sliding away as the conflicts piled up inside the tortured robot’s mind. “We know,” she said at last, admitting defeat. “And we understand. We know that you cannot tell us, and we will not ask.” It was pointless to go further. It was inconceivable that Kaelor would be willing or able to tell them, or that he would survive long enough to do so, even if he tried.

Lentrall looked at Fredda in surprise, and then relief. “Yes,” he said. “We will not ask. We see now that it would be futile to do so. I thought Dr. Leving might have some trick, some technique, some way of learning the truth without destroying you, but I see that I was wrong. We will not ask this of you, and we will not seek to gain the knowledge from you in other ways. This is our promise.”

“I join in this promise,” Fredda said.

“Hu-hu-humansss lie,” Kaelor said.

“We are not lying,” Fredda said, her voice as urgent as she could make it. “There would be nothing we could gain by asking you, and thus no motive for lying.”

“Yourrrr promisse does—does—does not apply to other humans.”

“We will keep the fact of what you know secret,” Lentrall said, a note of hysteria in his voice. “Kaelor, please! Don’t!”

“I tried tooo kee—keep the fact of wwwhat I knewww secret,” said Kaelor, “but yoooou realized that I had seeen what I saw, and that I woullld remember.” He paused a moment, as if to gather the strength to speak again. “Othhers could do the same,” he said in a voice that was suddenly little more than a whisper. “I cannot take thhat channnce.”

“Please!” Davlo cried out. “No!”

“Remaininng alivvve represents inaction,” Kaelor said, his voice suddenly growing stronger as he reached his decision. “I must act to prevent harm to humans.”

His eyes glowed brighter, his gaze turned from Davlo to Fredda, as if looking at each of them one last time, and then he looked straight ahead, at the wall, at nothing at all, at infinity. There was a low-pitched hum, the smell of burning insulation, and suddenly the light was gone from his eyes. His head sagged forward, and a thin wisp of smoke curled up from the base of his neck.

The room was silent. Fredda and Davlo looked at each other, and at the dead thing hanging on the frame in the center of the room.

“By all the forgotten gods,” Fredda whispered. “What have we done?”

“You did nothing, Doctor,” said Davlo, his voice nothing but a whisper as he fought to hold back a sob. “Nothing but help me do what I would have done. But as for me,” he said, his voice close to cracking, “I’ll tell you what I’ve done.”

He moved a step or two forward, and looked up at Kaelor’s body.

“I’ve just killed the closest thing to a friend I’ve ever had.”

JADELO GILDERN LIKED to tell himself that his job was to guess—and to guess correctly. The job of an intelligence chief was not to know everything. That was impossible. But a good intelligence chief was capable of seeing the whole puzzle when many of the pieces were lost, or hidden, or even disguised. A good intel chief could see the underlying pattern, take what he knew of the facts, what he knew of the personalities involved and figure out how they would interact. He could calculate what a person’s words and actions—or absence of words and actions—actually meant.

And as he sat in his office in the Ironhead Building, and thought over the situation, he was close to reaching an interesting conclusion. He was almost tempted to go the whole distance now. He knew it had to be the Settlers behind the Government Tower chaos, and it took no excess of brainpower to guess that they had been after Lentrall. And Gildern knew exactly what other steps he himself would have taken to suppress the information Lentrall had. Presumably the Settler leaders, Tonya Welton and Cinta Melloy, had as much sense as he did.

That much was all speculative, of course. However, one thing he did know to something like a certainty. He had already divined where Kresh had vanished to. Gildern had been able to use the Ironhead taps into the air traffic control system, and spot three long-range aircar flights, two starting at the governor’s private residence, and one terminating there. One, the first, had been untraceable in the storm. The return flight of the same vehicle had come in from precisely one hundred and eighty degrees away from the direction of Purgatory. That was exactly the sort of thing a robot would do if told to take evasive action. And then, a third flight, with a flight plan filed, showing a destination of First Circle, a small and far-off suburb of Hades. First Circle’s air traffic control had no record of the aircar arriving. Either it had crashed, or it had gone somewhere else. Gildern could guess where.

Three flights. One to carry Kresh, one to ferry back the aircar, and one to transport others to his side—perhaps his wife. But even without the return flight pointing in precisely the opposite direction, Gildern would have guessed Purgatory. One had to consider where the man would want to go at such a time. It was almost inevitable that he had gone off to consult the experts at the Terraforming Center on Purgatory. No, finding the man would be no problem. He would either be at the Center, or at the Winter Residence. He, Gildern, could get in an aircar and be face to face with the man in four hours’ time.

But would it be worth the trip? Had he worked out the rest of it properly?

There was, happily enough, a way to find out. Simcor Beddle had been good enough to inform Gildern what he was about to say in the speech he had decided to make. Gildern had felt a certain degree of surprise that Beddle was ready to take such daring steps. But he was not beneath using his master, when his master’s actions suited his purposes. Gildern was always prepared to manipulate Beddle in order to achieve some private agenda of his own.

But this time Beddle had needed no prodding, no buttering up, no encouragement. For once, Gildern had not had to feed an idea to Beddle, and then convince Beddle the idea was his. For once, Beddle was acting on his own.

If Beddle’s speech did not provoke a particular and immediate reaction from Alvar Kresh, then Gildern would know the governor was in trouble, and know it to such a high probability that it would be more accurate to call it a certainty. Gildern smiled. That would be most pleasant.

For then Gildern would be in a position to do the governor a little favor, while serving his own master at the same time.

And there were worse things in the universe than a planetary governor owing one a favor.

GAMBLE, SIMCOR BEDDLE told himself. A wise man knows when it is time to gamble, and now is the time. He drew himself up to his full height behind the lectern—aided not a little bit by the tall step discreetly hidden place behind it for that purpose—and looked squarely into the camera.

“I am here,” he said, “in order to make two announcements that I think you will find surprising.” An excited murmur filled the room—or at least it seemed to do so. There was no one in the room, other than Beddle and the robots operating the cameras and the sound system, but there was no need for the world to know that. Nor was “here” any place in particular, other than the broadcast studio in the basement of the Ironhead Building. He had not said where he was, but he had certainly made it sound like an important place, an important event, and that was all that mattered.

He had help, of course. The robot operating the sound system knew his business, and knew just how to create a spurious murmur of surprise, the shifting of seats that were not there and even the subdued and subtle hum of imaginary datapads as nonexistent reporters took their notional notes.

All of it worked on the subconscious, but it worked all the same. Simcor Beddle knew how the media operated on Inferno. He was feeding his speech direct to the news nets, but hardly anyone would see the speech now, live. It would be edited down, with a snippet presented as if it were the whole thing.

People would see perhaps ninety seconds of his speech on one or the other of the news services, a short enough slice of time that they would not expect a description of where and why the speech was made. They would hear the background sounds under his voice, see the opulent red curtains behind his head, catch the implication in his words that he was speaking to some very important group at some very important event. Subtle stuff. Subtle enough that the viewers would not quite know why they thought it was important, but the impression would be placed in their minds all the same. Simcor Beddle, the leader of the Ironheads himself, had addressed some group one didn’t quite catch the name of, and there had dropped his bombshells on a waiting world. When one had sufficient control over fantasy, one had no need of reality.

Beddle looked alertly out over the audience that wasn’t there. “First, I would like to confirm the story that has been circulating since last night.” He paused dramatically. “There is indeed a government plan to drop a comet onto this planet, on the Utopia region to be precise. The impact will assist in the formation of a Polar Sea, which will, in turn, enhance Inferno’s planetary climate.” The sound effects robots brought up the appropriate murmur of astonishment and surprise. “The project is very much in its planning stages, and the government is not yet definitely committed to it. However, the government is making its preparations just the same, as well they should be. Time is short. The comet in question was discovered only recently, and preparations must be made in advance of the final decision to proceed if there is to be time to make it happen.”

Simcor paused once more, and looked directly into the camera. “This brings me to my second announcement. There are those among you who will find it even more startling than the first. I fully support the government plan. I have seen certain planning documents and results projections and risk assessments. There are, beyond question, serious dangers involved. Nor will the task be easy. There is a tremendous amount of work that must be done in a very short time. But I have also seen the estimates of the probable fate of our planet, what will happen here if we don’t seize this chance. Suffice it to say those projections are grim. Grim enough that I have concluded we must seize this chance, risks and all.” Simcor paused once again, and looked about the room with a meaningful expression. “While I support the comet-impact plan, I must take the government to task most severely for the manner in which it has concealed its plans from you, the people of Inferno. Surely no one can question that this project will affect every man and woman on this planet. The decision should not have been made in secret.”

Beddle paused, and smiled warmly. “But that is now behind us. It is now up to each and every one of us to support this bold plan, this plan which, if all goes well, will bring us all forward into a brighter and more prosperous future. However, even as we make this bold step forward, it is important that we understand that some among us will be forced to sacrifice all they have for the sake of the greater good. Those who live and work where the comet is to strike will lose everything—unless we help.

“The government is of course working on evacuation plans and procedures for transporting goods and equipment out of the impact zone. However, there is only so much government can do—or at least only so much that it is willing to do. For that reason, I make one final announcement. The Ironhead Party will throw its full resources behind the effort to assist those dislocated by this massive undertaking. We will take care of our neighbors, our brothers and our sisters of the Utopia region, in this, their hour of need. I myself will oversee our assistance program, and I will shortly depart the city of Hades for an inspection tour of the Utopia region. The impact of this comet on our planet represents danger at worst and dislocation at best for many people, but, at the end of the day, it represents hope—perhaps the last and best hope—for the future of our world. Let us prepare well to receive this gift from the heavens.”

Simcor Beddle looked once more about the empty room as the sound of simulated spontaneous applause filled the air. He nodded appreciatively, and then looked straight into the camera. “Thank you all,” he said, and as the camera zoomed in on his face before fading out, he managed to look as if he meant it.

“WELL,” SAID ALVAR Kresh, “that could have been worse.”

“Considering it’s Simcor Beddle, I’d say you got off pretty lightly,” said Fredda. She yawned and stretched and stood up from the couch. If she stayed sitting down much longer, she was going to doze right off.

Fredda had just arrived on Purgatory an hour or so before, and it had been a hell of a day before she had even started her trip. The after-hours news interview and the midmorning shambles at Davlo Lentrall’s place had been capped off with Oberon’s arrival. He had delivered his message from Alvar, asking Fredda to join him. She and Donald had flown to Purgatory by as fast an evasive route as Donald could manage. Even so, it had been close to dusk before they had met up with Alvar here at the governor’s Winter Residence.

Now, here she and Donald were, with the evening closing in—and their problems closing in just as fast. Fredda looked around herself and shivered. Governor Chanto Grieg had been murdered in this house, shot to death in his bed. Of course that had happened in a completely different part of the house than the wing they were occupying, but even so, the Winter Residence was never going to be a comfortable place for Fredda.

Or, more than likely, for her husband. Alvar had not offered much resistance when Fredda had insisted that he use some other suite of rooms for his private quarters. Maybe some future governor, in some time when the story of Grieg’s death was just a bit of history would be able to put his or her bed in the room where Grieg had died. But Alvar had found the body, and she, herself, had seen the corpse in the bed. No. They would sleep elsewhere. It was bad enough being in the same house. Those future governors could sleep where they liked. Assuming the planet survived that long.

“We got off so lightly I almost wonder if that was Beddle,” said Alvar, still sitting back on the couch facing the viewscreen. “He had every chance to tear into us, but he didn’t. I must say it’s a little disconcerting to have the man on our side.”

“Well, he did get in one set of digs,” said Fredda. “The secrecy angle is going to hurt us. We have to announce something.”

“What?” asked Alvar. “That we haven’t quite decided about the whole plan, and by the way, we seem to have misplaced the comet?” Alvar stopped and thought for a minute. “Hmmm. That would do Beddle a world of good. Suppose he knew we didn’t have a lock on the comet? Then he could come out all in favor of the bold government program for the comet impact project for the specific purpose of forcing us to admit that we had lost the thing, and couldn’t deliver. We’d look as bad as—as—”

“As we do right now,” Fredda said with a sad little smile. “And there’s no way we can find that damned thing again?”

“Let’s check again,” he said. He turned to Donald, who was standing by the comm center controls. “Donald, activate a direct audio link to Units Dum and Dee.”

“Yes, sir.” Donald pressed a series of control studs and spoke again. “The link is open, sir.”

“Howww may wweee be of assistance, Governorrr?” Two disembodied voices, speaking in unison, suddenly spoke out of the middle of the air.

Fredda jumped half a meter straight up in the air. “That is the weirdest—”

“Shhh,” said Alvar, waving for her to be quiet. “Later. Units Dum and Dee. Based on your current refined estimates of the work required once the comet is located, calculate the most likely length of time left between now and when the work must commence.”

“Therrree are mannny vvarrriables,” the doubled voice replied. “Weee willll attemmmpt a usseful appproximaation.” There was a brief pause and then one of the two voices, the higher-pitched, feminine-sounding one, spoke by itself. “Twelve standard days, four standard hours, and fifty-two standard minutes. I should note that estimate is based on having the complete comet task force in order and on standby for immediate launch.”

“Very good,” said Kresh. “Based on the best current data and the current search schedule, what are the odds of relocating Comet Grieg within twelve standard days?”

“Theee oddss arrre approximatellly onnne inn elllevennn, or approximately nine percent,” the double voice replied.

“Give us a range of representative values,” Kresh said.

The deeper-pitched, mechanical voice spoke by itself. “In percentile terms, odds are point five percent for relocation in one day. One point two percent in three days. Four percent in six days. Six point one percent in eight days. Nine percent in twelve days. Twenty percent in fifteen—”

“When do the odds reach, oh, ninety-five percent?”

The feminine voice took over. “The odds improve rapidly as possibilities are rejected and the search area is reduced. At the same time, the comet is growing closer, and beginning to increase in brightness as it is heated by the sun. This also helps. The odds for relocation pass the ninety-five percent point in about twenty-six days.”

“Too little, too late,” said Fredda.

“Yes,” said Alvar, his tone of voice saying far more than that single word. He sighed. “Deep space all around, but I’m tired,” he said. “All right, Units Dum and Dee. That will be all.” He signaled for Donald to cut the connection.

Fredda watched her husband as he stared straight ahead at the blank wall in front of him, a deep frown on his face. “One chance in eleven,” he said. “Is that what it comes down to? The planet has a nine percent chance, if we do everything exactly right?”

“It could be,” Fredda said, returning to the couch and sitting next to him. “Are we doing everything, and are we doing it right?”

Alvar Kresh rubbed his eyes. “I think so,” he said, and yawned hugely. “I can’t remember the last time I really slept.” He shook his head and blinked a time or two. “I’ve got a spaceside team working around the clock, getting the equipment together to make the intercept. We haven’t started on the actual evacuation of the Utopia region yet—and I hope to the devil that Beddle hasn’t just started a panic out there with that little speech. But we’re getting the evac plan ready to go. The area’s pretty thinly populated, and Donald tells me the people who know these things feel it would be better to take a bit more time planning, even if it means starting a bit later.”

“One thing I can tell you your evacuation experts might not have told you,” said Fredda. “Make sure it’s a total evacuation, and that you can prove it’s total. Leave one person there—or even leave open the possibility that one person is out there—and you’re going to be knee-deep in overstressed Three-Law robots trying to pull off a rescue.”

“I’m not going to worry about losing a few robots in comparison to saving the whole planet.”

“No, of course not,” Fredda said. But she thought of Kaelor’s death a few hours before, and could not help but wonder if she would be quite as careless about the lives of robots in the future. “But those robots could cause a great deal of trouble. Even if you can prove there’s no one left in all of Utopia, a lot of robots are going to feel strong First Law pressure to stop the comet impact, any way they can. After all, the comet sure as hell represents danger to humans. More than likely, someone is going to die in a building collapse or an aircar caught by the shockwave, or whatever.”

“Maybe so, but how could the robots stop it?” Kresh asked.

“For starters, is that an all-human crew on the spaceside team? You have to assume that any robots on that job will do their best to sabotage the job. Even a low-function fetch-and-carry robot will have enough capacity to realize that an incoming comet represents danger.”

“Burning devils,” said Kresh. “I hadn’t thought of that. I hope someone else has, but we’ve got to damn well make sure the crews on those ships are all human. Donald, pass that order and explain—” Alvar stopped and looked at Donald. “No, wait a minute,” he said. “I can’t use you to pass the order for the same reason. Your First Law means you won’t cooperate either.”

“On the contrary, sir. I am able to pass the message.”

Fredda looked at Donald in surprise. “But don’t you feel any First Law conflict?” she asked.

“A certain amount of it, Dr. Leving, but as you well know, a properly designed Three Law robot feels some First Law stress most of the time. Virtually every circumstance includes some danger, if only low-probability-danger, for a human. A human could drown swallowing a glass of water, or catch a deadly plague by shaking hands with an off-planet visitor. Such dangers are not enough to force a robot to action, but are enough to make the First Law felt. There is some potential danger here, yes, but you designed me as a police robot, and I am equipped to deal with more risk than most robots.”

“I see,” said Kresh, keeping his voice very steady. Fredda had the very strong impression that she was going to have to ask him about all this in the very near future. “But, meaning no offense,” said Kresh, “I think it might be best if I took care of that order myself. I’ll call the spaceside planning group, banning all robots from the operation, and explaining why.”

“No offense taken, sir. You must take into account the possibility that I am deceiving you. I can imagine a scenario where I would disobey that order, and see to it that as many robots as possible went into the spaceside operation in order to sabotage it.”

Kresh gave Donald a quizzical look. “My imagination works a lot like yours,” he said. He turned to Fredda. “Donald’s good example to the contrary,” he said, “I don’t think I’ve ever been in a situation where robots have done so much to make my job difficult. To make everyone’s job difficult.”

“That’s what you get when you try and take risks, even necessary risks, around robots,” Fredda said. “I think the real story is that none of us have ever really tried to take risks before.”

“And robots don’t like risks,” said Kresh. “They’re going to keep us all so safe they’re going to get us all killed. Sooner or later we’re going to have to—”

“Excuse me, Governor,” said Donald. “The Residence security system has alerted me via hyperwave that an aircar is landing in the visitor’s parking area.”

“Who the devil has found me here?” Kresh muttered.

“It could just be some tourist who wants to get a look at the Winter Residence,” Fredda said.

“Not with our luck,” he said, getting up. He crossed the room and sat down at the comm center. He punched in the proper commands, and brought up the view from the main entrance security cameras. There was the car, all right. And someone getting out. Kresh zoomed in on the figure, pulled in to a tight head-and-shoulders shot, and set the system to track the shot automatically. It was a man, his back to the camera as he climbed out of his armored long-range aircar. He turned around, and looked straight toward the concealed surveillance camera, as if he knew exactly where it was. He smiled and waved…

“What the devil is he doing here?” Kresh muttered to himself.

“Who is it?” Fredda asked, coming up to stand behind her husband.

“Gildern,” said Kresh. “Jadelo Gildern. The Ironhead chief of security.” He frowned at the image on the screen. “He’s no tourist come to get a look at the place. He knows we’re here. I think you’d better go let him in, Donald. Bring him to the library. We’ll wait for him there.”

“Yes, sir,” said Donald.

“What does he want?” Fredda asked. “Why is he here?”

Kresh shut off the comm system and stood up. “From what I know of Gildern, there’s only one thing he ever wants,” he said. “What he wants is a better deal for Jadelo Gildern.”

“GOOD EVENING, MASTER Gildern,” said the short blue robot who met him at the door. “The Governor has ordered me to escort you to him.”

Gildern nodded curtly. Others might waste their time in courtesy to robots, but Ironheads did not. Besides, he had other things on his mind. It would be best for all concerned if this interview went very quickly indeed. There were unquestionably risks in the game he was playing, and he saw no benefit at all in making those risks greater. The blue robot. Donald 111. That was its name. Built by Leving herself, and Kresh’s personal assistant since he was sheriff. Deliberately designed to seem unthreatening. Frequently underestimated. Gildern smiled to himself. He often found it calming to remember just how much he had in his dossiers.

The robot led them through a large central court and down a corridor leading off to the right, then stopped at the fourth of a series of identical doors. Gildern had memorized the layout of the Residence on the flight down. This was the library.

The robot opened the door and Gildern stepped inside behind him. And there were Kresh and Leving themselves. Both here, precisely as he had guessed. Kresh seated behind a desk, Leving sitting in one of the two chair facing the desk.

“Jadelo Gildern of the Ironheads,” the robot announced, and backed away into a robot niche.

“Governor, Dr. Leving,” said Gildern. “Thank you so much for allowing me to arrive so—informally. I think you will find it to our mutual benefit if this visit is kept as quiet as possible.”

“What do you want, Mr. Gildern?” the governor asked, his voice calm and imperturbable.

Gildern walked up to the desk, made the slightest of bows to Dr. Leving, and smiled at Kresh. “I’m here to give you a present, Governor. Something you’ve wanted for quite some time.”

“And in return?” Kresh asked, his voice and face still hard and expressionless.

“And in return, I simply ask that you do not ask, now or in the future, how I got it. No investigation, no inquiry, no official legal proceedings or private researching.”

“You got it illegally,” Kresh said.

“My condition is that you do not ask such questions.”

“Just now I made a statement,” said Kresh. “I asked no question. And I’m not accepting any conditions. I’m sworn to uphold the law, as you may recall. And I might add that it is generally unwise to request an illegal service of a government official in front of witnesses.” He nodded toward Leving and the robot in its niche.

Gildern hesitated. It wasn’t supposed to have played this way. He had planned on being able to bully Kresh, get what he wanted. But the man had called his bluff. Gildern needed Kresh to have the material, as much as Kresh needed to have it. All of the Ironhead plans, all of Gildern’s plans, would otherwise crumble. Gildern realized that he had made a serious miscalculation. He was too used to working in a world of people who could be coerced, manipulated, led, and blackmailed. He had assumed Kresh would be equally pliable. But Kresh was an ex-police chief who handled cases personally when he saw fit. What reason would he have to be cowed by Gildern? “I don’t want any questions asked,” he said again, in a tone of voice that even he found less than commanding.

“Then I suggest you take your business elsewhere,” said Kresh. “I have had a hard enough couple of days without being threatened and blackmailed by the likes of you. Get out.”

A flash of anger played over Gildern. He opened his mouth to protest, and, then thought better of it. He could play this with his pride, his ego, and lose everything. Or he could play it with his common sense and win it all. And then, later, once he had won, won it all, he would be in a position to indulge his pride. “Very well,” he said. “No conditions.” He pulled a small blue cube out of the pocket of his blouse and set it on the table. “Take it with my compliments.”

He bowed once more to Dr. Leving, turned and headed toward the door.

“Wait!” Dr. Leving called out. “What is it? What’s in that datacube?”

Gildern looked back toward her with genuine surprise. “You haven’t figured that out? I expect your husband has.”

“It took me a minute, but I have,” said Kresh. “Lentrall told me there were two break-ins at his lab. One to steal copies of his data, and the other to destroy the originals. I should have figured it out long ago. Lucky for you I didn’t.”

“Will one of you tell me?” Fredda demanded. “What’s in that thing?”

Gildern smiled unpleasantly at her. “Why, Comet Grieg, of course. All of Dr. Lentrall’s calculations and data regarding its location, trajectory, mass, and so on. It’s all there.” He looked from Leving to Kresh and nodded his head at the governor. “Now, then, if you’ll excuse me, I must leave at once. I’m expected at some little town called Depot in the middle of the Utopia region. There’s no suborbital service from here. I’m going to have to fly in a long-range aircar, and it is going to be a very long flight indeed.”

Kresh picked up the cube and smiled coldly at Gildern. “See our friend out, Donald,” he said. “I have a speech to prepare.”

“I look forward to hearing it, Governor,” Gildern said. And with that, he followed the small blue robot out of the room.

LANCON-03 PLACED THE call to Anshaw as soon as Governor Alvar Kresh had completed his speech, in which Kresh had just confirmed that the government was working on the comet project, and that the Utopia region was the target. Lancon-03 knew perfectly well that there was little Gubber Anshaw could do, but on the other hand, the New Law robots had precious few friends, and now was the moment when they would need all the help they could get.

Lancon-03 was still using the city leader’s office in Prospero’s absence. It had one of the few fully shielded and untraceable hyperwave sets in the city. Of course, if Valhalla were about to be destroyed, how much difference could it make if someone managed to tap the call and zero in on their location?

Gubber Anshaw’s image appeared on the screen. “I was expecting your call, friend Lancon,” he said without preamble. “I take it you heard the governor’s speech?”

“I did,” Lancon replied. “I still have trouble believing they truly intend to drop a comet on us.”

“Denial is a human trait,” said Anshaw. “I would not advise you to indulge in it. The governor has confirmed the stories regarding the comet, and that is all there is to it. Now you must—we all must—deal with available reality. What is Prospero’s opinion of the situation?”

“Prospero continues to be unreachable. My expectation is that he was alarmed by the Government Tower incident, or perhaps learned something of a worrying nature. If that were the case, he would elect to travel as discreetly as possible, and would not risk needless communication. At least that is what I hope has happened. Otherwise it might well be that he is dead.”

“Let’s hope not,” Gubber said.

“Dr. Anshaw, what are we supposed to do?” Lancon-03 asked. “How can we stop this thing from happening?”

“You cannot,” said Gubber. “Now, no one can. Too much has been committed to it, too much has been promised, too much energy has been expended. You have told me many times how much New Law robots want to survive. Now they must survive this, as well.”

“But how are we to do that?” Lancon-03 asked.

Gubber Anshaw shook his head sadly. “I don’t know,” he said. “If I think of anything, I’ll let you know.”

GUBBER SAID HIS goodbyes to Lancon-03, wondering just how permanent they were, and returned to his wife’s office. Any hope that Tonya might have calmed down while he was out of the room were dispelled as soon as he set foot in the room. He glanced toward the far end of the room, where Cinta Melloy was sitting. Cinta caught his eye, and shrugged helplessly. Clearly Cinta had decided there was nothing for it but to wait out the storm.

“The fools,” said Tonya Welton through clenched teeth as she paced the floor. “The bloody, stupid fools.” Two commentators were on the comm screen, in the midst of animated debate on the subject of Comet Grieg. But Tonya slapped at the comm control panel and the image died, cutting them off in midword.

“I can’t listen to any more of this,” she said, still fuming. “Damn that Kresh! Not only did he publicly commit to the plan, he went and broadcast the precise orbital data for Comet Grieg. It was hard enough erasing one man’s computer files, and we didn’t even manage the kidnapping. Now what the hell do we do? Erase the coordinates from every comm center on the planet?”

It took a moment for Gubber to realize the implications of what Tonya was saying. “You mean—you mean you were the ones who tried to kidnap Lentrall?” he asked.

“Of course we were,” Tonya said. “To prevent exactly this from happening. No one else seemed interested in stopping the comet crash.”

Gubber nodded blankly. Of course it was Tonya. He should have known it in the first place. Why was he always so startled to discover her ruthless streak? When it came to politics, Tonya Welton took no prisoners. “Won’t the CIP find out?” he asked. The question sounded foolish, even to him, but somehow he could think of nothing else to say.

“Probably,” said Tonya, her tone brisk and distracted. “Sooner or later. If we all live that long.” She turned toward Cinta Melloy. “How the devil did they do it?” she demanded. “How did they reconstruct the comet data?”

“Does it matter?” Cinta asked. “We always knew there was a chance that there would be a backup copy we missed.” Cinta Melloy sat on the couch and watched her boss stalking back and forth across the floor. “It’s not important how they did it. The point is that they did.”

But Tonya was barely listening. Instead she kept pacing, her face a study in furious concentration. “Beddle,” she said at last. “We’ve been pretty sure for a while that informant of ours was working both sides of the street. And then, all of a sudden Beddle’s all for the government, all for the comet plan, before Kresh makes a public statement. Suppose our informant fed the data to Beddle and Beddle fed it back to Kresh before Kresh went to ground?”

Cinta shrugged. “It’s possible. We tracked Gildern’s long-range aircar headed toward Purgatory. We know from the broadcast just now that Kresh is working at the Terraforming Center there. But what does it matter?”

“It means that Beddle and Gildern bear watching, that’s what,” said Tonya. “It means they may behind this whole suicidal operation. Why else would they support the government? When was the last time they did that?”

Gubber Anshaw crossed the room and sat down next to Cinta Melloy. He looked from Tonya to Cinta, and had a feeling that he knew what the security officer was thinking. Even with his thoughts in a whirl, he was thinking the same thing. Tonya was obsessing on this crisis. He had known the truth about Government Tower Plaza for only a few minutes, but he knew Tonya well. If she were frantic enough, desperate enough, to have ordered that fiasco, Dark Space alone knew what else she would be capable of.

“So what do we do about it all?” Cinta asked, her voice a study in neutrality.

“Why ask her to choose now?” Gubber asked. “There’s no need for rushed decisions. Better to take time, to study things calmly first.”

Tonya wheeled about and glared at both of them. “You’re handling me,” she said. “Humoring me. Don’t. I’m still in command of the Settlers on this planet, and don’t you forget it.”

“I’m not forgetting it for one minute,” Cinta said. “And that’s what scares the living daylights out of me. You’re in charge, and I’ll follow your orders. But your orders have not had good results in recent days.”

The look on Tonya’s face was indescribable, a tangle of fear, anger, mad fury, hatred, and shame. Gubber saw Tonya raise her hand, as if to strike Cinta in the face.

“No!” he cried out. “No.”

Tonya looked at him in shock, as if she not were surprised to see him there.

“No,” he said again, surprised by the firmness in his own voice. When had he even spoken to Tonya, or anyone else, for that matter, in this tone of voice? “Foolishness will accomplish nothing,” he went on. “Now is the time to pause and consider. You are the leader here. Our leader. No one disputes that. So lead us. But do not lead us with fear, or anger, or frustration, or because you do not approve of the available situation. Lead us with reason and care.”

Tonya looked at him in shock. “How dare you!” she said. “How dare you speak to me that way?”

“I—I dare because no one else can, and someone must,” Gubber said, his voice unsteadier than he would have liked. “Cinta just tried, and you wanted to strike her for telling the truth. Well, strike me as well, if that is the way of things. I won’t stop you.”

His heart was pounding, but he forced himself to look up at her steadily. She lowered her hand, than raised it again, but then, at last, let it drop to her side. She turned and walked to the other side of the room, and dropped heavily into a chair. “You’re right,” she said. “But I sure as hell wish you weren’t.”

The silence in the room was a near-palpable thing for a time. Tonya sat in her chair, staring at nothing at all. Cinta sat stone-still, her gaze moving back and forth between Gubber and Tonya.

Gubber knew Tonya. He knew she only needed another push, another nudge in the proper direction. And it was plainly up to him to provide that nudge. This was up to him. He cleared his throat and began, speaking in a calm, casual tone that no doubt fooled no one at all. “I’ve just finished speaking with a New Law robot by the name of Lancon-03. Prospero seems to have dropped out of sight, and left her in charge. She had heard the governor’s speech as well, and she called me, asking for advice as to what the New Law Robots should do. That comet is going to drop right on top of them. I couldn’t think of anything to suggest. Can—can you think of anything?”

Tonya laughed wearily and shook her head. “Oh, Gubber. Dear, dear Gubber. The only thing to tell them is to accept the available universe and the bad situation they are in, and make the best of it. And, of course, their situation is much worse than ours. I think you have made your point.”

“Very well, then,” he said, pressing one last time, “what are we going to do?”

Tonya leaned back against the back of her chair, rubbed her eyes, and stared at the ceiling. “We are going to do two things. First off, I want as close a watch as possible put on Beddle and Gildern. There is more going on there than meets the eye. Jadelo Gildern never does anything for just one reason. I want to know what his hidden agendas are this time.”

“We’re already working on it,” Cinta said, plainly relieved that Gubber had managed to get Tonya to behave sensibly. “What’s the second thing?”

“The second thing is that we are going to admit defeat.”

“Ma’am?” Cinta asked, shifting on her seat and looking at Tonya with a puzzled expression.

“Gubber’s right. There’s no stopping it now,” said Tonya, gesturing toward the sky. “They know where the comet is, and they’re going to go for it, and drop it right down on top of their own damn planet, and trust that every little thing will go right, so they don’t get everyone killed. I still don’t believe they can do it. They don’t have the skill or the experience. And I’ve seen what happens to a world when an attempt like this goes wrong. Some old nightmares have come back to me since we found out about this. I think they’re going to kill the planet. But short of shooting down their space fleet, there’s no way to stop them.”

Shooting down their fleet? Gubber thought he had talked her around. But maybe not. For a moment of heart-pounding terror, Gubber thought Tonya had gone far enough around the bend to order just such a thing. “You’re not—”

“No,” said Tonya wearily. “I’m not. Mostly because I don’t think we have the firepower on hand to do it—and because I’m not sure anyone would obey any such orders. But absent that option, there is no way we can stop them.” Tonya stood up and went back to the comm station. She switched it back on, activated the full-wall flatscreen, and brought up a view of the night sky as seen from the cameras up on the surface. It was a scene of heart-stopping loveliness, the jet-black sky blanketed with a cloud of dimmer stars setting off the larger, brighter ones, white and yellow and blue and red points of color glowing in the night. “And therefore we might as well see to it that they do it right. I’m going to go back to my office and draft an announcement offering our complete cooperation, and access to all our expertise in this area. Maybe we can at least keep the damage to a minimum.”

Tonya Welton bunched up her shoulders and then let them go limp, a gesture of humiliation and resignation and frustration, all in one. “And of course there is the little matter of their tracking down whoever was responsible for the Plaza attack. Maybe if we start helping out, that will muddy the trail, keep them from kicking us off the planet.”

She was silent again for a moment, and when she spoke, she all but choked on the emotion she had been struggling to hold in. Anger, frustration, shame, fear, all of them and more welled up in her voice. It was plain that the words were pure gall to her. But it was also plain that words had to be spoken. “And if, or rather when, they do catch us,” she said, “maybe it will count in our favor if we’ve already made amends.”

THE AIRCAR CRUISED slowly along the silent, empty streets of Depot in the pre-morning darkness and came to a halt not far from the edge of the small town. Prospero operated the controls with the relaxed skill of a master pilot and set the craft down in a small hollow, well out of sight from any of the surrounding buildings.

“Here’s where I get out,” said Norlan Fiyle with undisguised relief. He stood up and opened the side passenger door of the aircar. He climbed down out of the vehicle and stretched his arms and legs gratefully. “No offense to either of you,” he said through the open door, “but I’m very glad to get out of that damned car.”

“And what about you, friend Caliban?” Prospero said. “This is your last chance. Are you sure you won’t go with me?”

“No, friend Prospero,” said Caliban. “Go to Valhalla. You are needed there far more than I. Besides, you might well need a friend on the scene here in Depot. It is better if I remain.” Caliban’s reasons were true enough as far as they went, but they were far from the whole truth. The core, basic, essential reason was that he no longer wished to be close to Prospero, either literally or ideologically. There had been time enough and more to think things over on the long and wearying trip. Prospero was a magnet for risk, for danger. Caliban had had enough of risking his life in the name of causes that were not his own. “I will remain here,” said Caliban. “I will remain in Depot.”

Fiyle smiled thoughtfully. “Somehow, that sounds very familiar”, he said. “Prospero used almost exactly those words when he and I parted company on Purgatory, years ago.”

“Let us hope that the journey that begins with this parting works out somewhat better than that one did,” Prospero said.

“Well, at least this time you’re the one doing the traveling, not me,” said Fiyle. “This is the end of the line for me. At least until the comet hits.”

“What will you do, Fiyle?” Caliban asked. “Where will you go?”

The human shook his head back and forth, shrugged, and smiled. “I haven’t the faintest idea. Out. Away. Someplace they won’t look for me. Someplace I can start over. But I’ll stay in Depot for a while. No one knows me here.”

Depot was the largest human settlement in the Utopia region, which was not saying a great deal. As its name implied, it was little more than a shipping point for the small and scattered settlements of that part of eastern Terra Grande.

“But why?” asked Caliban. “We have reasons for coming here, but why should you want to hide out in a town that’s going to be destroyed?” said Caliban.

“Precisely because it’s going to be destroyed,” said Fiyle with a grin. “That right there ought to make it a great place to disappear from. I can cook myself up a new identity, based in Depot, and say whatever I want about the new me. How’s anyone going to check the records, when Depot is a smoldering ruin? And maybe I’ll have a chance to fiddle the town records before they archive them and ship them off. Maybe the records will wind up saying I’m a prosperous businessman with a large bank balance. Once the town is flattened and the population is dispersed, who’ll be able to know for sure that I’m not?”

Caliban looked steadily at Fiyle for a full five seconds before he responded. “I must say you do think ahead,” he said. “I suppose it is yet another insight into the criminal mind.”

Fiyle grinned broadly and laughed. “Or perhaps,” he said, “merely an insight into the human mind.”

“That is a plausible suggestion,” said Prospero, “and therefore a most disturbing one. Farewell, Caliban. Farewell, Norlan Fiyle.”

“So long, Prospero,” Fiyle replied, a big sidelong grin on his exhausted face.

And then there was no more to say. Caliban rose up from his seat and climbed down from the aircar. Fiyle closed the door from the outside, and the aircar lifted off, straight up, leaving Caliban and Fiyle behind.

“Well,” said Fiyle, “if I’m going to try and disappear, might as well get started right away. So long, Caliban.”

“Goodbye, Fiyle,” Caliban said. “Take care.”

Norlan smiled again. “You do the same,” he said. He waved, turned around, and started walking down the still-darkened street.

Caliban looked back toward the aircar as it rose up and swing around to a southerly heading, a small dark smudge of deeper darkness against the slow-brightening dawn. Alone. That was the way he had wanted it. But even so, he could not rid himself of the sense that he had just parted from a vital part of himself. He had been, or at least almost been, one with the New Law robots for a long time.

And now. Now he was Caliban, Caliban the No Law robot. Caliban by himself, once again.

Somehow the thought did not bring him as much pleasure as he had expected.

NORLAN FIYLE FELT good as he strolled about the town. There was something about being out under an open sky, about knowing that the people looking for him were quite literally on the other side of the world. It felt good, very good, to walk along in the early morning through a town that was just beginning to wake up, knowing that he was out from under, that the game he had been playing was over and done with. It had not been easy playing the Settlers off against the Ironheads, all the while steering clear of the Inferno police in the middle. In the short term, a fellow could have a good run of luck at that sort of thing, bucking the odds, taking chances and getting away with it. But sooner or later, the odds would catch up. They had to. Law of nature. In the long run, there was only one way to win that sort of game—by getting out of it the first moment you could.

And he had. He was out.

He found a little café that served a very passable breakfast. He ate a leisurely meal at the table by the front window, and spent an hour or two in that most enjoyable of pastimes—watching other people rushing off to work while being under no obligation to do any such thing himself.

He paid his bill in cash, exchanged a pleasantry or two with the handsome woman behind the counter who combined the functions of manager, waitress, cook, and cashier, and ambled out into the dusty main street of Depot.

The next step was to find a place to stay, and then to pick up a few of the basic necessities. He had, after all, fled Hades with nothing but the clothes he was in, and a certain amount of cash. But Fiyle had lost everything he had a time or two before, and would quite likely do so again. The prospect did not bother him overmuch. There ought to be plenty of work in this town, seeing how the whole damn place was going to have to be packed up and shipped—

A hand came down on his shoulder. A man’s hand, small and thin-fingered, but wiry and strong.

“Dr. Ardosa,” a cool, unpleasant voice said in his ear. “Dr. Barnsell Ardosa. What a remarkable surprise to see you here, of all places. Except I suppose you’re not using that name anymore. Have you gone back to Norlan Fiyle for the time being? Or haven’t you picked out a new one yet?”

Fiyle turned around, and looked down just a trifle, straight into the eyes of Jadelo Gildern, the Ironhead chief of security. “Hello, Gildern,” he said slowly. “I suppose I might just as well stick with Norlan Fiyle, at least with you.”

Gildern smiled unpleasantly. “That makes sense to me,” he said. “But don’t you worry,” he said. “No one else needs to know who you really are—the Inferno police, for example, or the Settlers—as long as you keep me happy. Does that sound fair?”

“Yeah, sure,” said Fiyle, his voice a monotone.

“Good,” said Gildern. “Very good. Because until this very moment I was worrying about how I was going to staff things around here. It’s hard to find people with the right aptitude for intelligence work—especially among people who also have a strong motivation for keeping their employers happy.”

“Employers?” asked Fiyle, a cold, hard, knot forming in his stomach.

“That’s right,” said Gildern. “It’s your lucky day, Norlan. A very nice job opportunity has just fallen into your lap. Just between you and me, I don’t see how you can turn it down.”

Gildern stepped alongside Fiyle and put his hand on Fiyle’s forearm. It looked like a gentle, even friendly, gesture, but the fingers on his arm clamped down as tightly as any vise.

Jadelo Gildern led Norlan Fiyle away. And it was abundantly and unpleasantly clear to Norlan that he was nowhere near getting out of the game.
