Cascade Point

Cascade Point

In retrospect, I suppose I should have realized my number had come up on the universe's list right from the very start, right from the moment it became clear that I was going to be stuck with the job of welcoming the Aura Dancer's latest batch of passengers aboard. Still, I suppose it's just as well it was me and not Tobbar who let Rik Bradley and his psychiatrist onto my ship. There are some things that a captain should have no one to blame for but himself, and this was definitely in that category.

Right away I suppose that generates a lot of false impressions. A star liner captain, resplendent in white and gold, smiling toothily at elegantly dressed men and women as the ramp carries them through the polished entry portal—forget all of that. A tramp starmer isn't polished anywhere it doesn't absolutely have to be, the captain is lucky if he's got a clean jumpsuit—let alone some pseudo-military Christmas tree frippery—and the passengers we get are the steerage of the star- traveling community. And look it.

Don't get me wrong; I have nothing against passengers aboard my ship. As a matter of fact, putting extra cabins in the Dancer had been my idea to start with, and they'd all too often made the difference between profit and loss in our always marginal business. But one of the reasons I had gone into space in the first place was to avoid having to make small talk with strangers, and I would rather solo through four cascade points in a row than spend those agonizing minutes at the entry portal. In this case, though, I had no choice. Tobbar, our master of drivel— and thus the man unofficially in charge of civilian small talk—was up to his elbows in grease and balky hydraulics; and my second choice, Alana Keal, had finally gotten through to an equally balky tower controller who wanted to bump us ten ships back in the lift pattern. Which left exactly one person—me—because there was no one else I'd trust with giving a good first impression of my ship to paying customers. And so I was the one standing on the ramp when Bradley and his eleven fellow passengers hoved into sight.

They ranged from semiscruffy to respectable-but-not-rich—about par for the Dancer—but even in such a diverse group Bradley stood out like a red light on the status board. He was reasonably good-looking, reasonably average in height and build; but there was something in the way he walked that immediately caught my attention. Sort of a cross between nervous fear and something I couldn't help but identify as swagger. The mix was so good that it was several seconds before it occurred to me how mutually contradictory the two impressions were, and the realization left me feeling more uncomfortable than I already did.

Bradley was eighth in line, with the result that my first seven greetings were carried out without a lot of attention from my conscious mind—which I'm sure only helped. Even standing still, I quickly discovered, Bradley's strangeness made itself apparent, both in his posture and also in his face and eyes. Especially his eyes.

Finally it was his turn at the head of the line. "Good morning, sir," I said, shaking his hand. "I'm Captain Pall Durriken. Welcome aboard."

"Thank you." His voice was bravely uncertain, the sort my mother used to describe as mousy. His eyes flicked the length of the Dancer, darted once into the portal, and returned to my face. "How often do ships like this crash?" he asked.

I hadn't expected any questions quite so blunt, but the fact that it was outside the realm of small talk made it easy to handle. "Hardly ever," I told him. "The last published figures showed a death rate of less than one per million passengers. You're more likely to be hit by a chunk of roof tile off the tower over there."

He actually cringed, turning halfway around to look at the tower. I hadn't dreamed he would take my comment so seriously, but before I could get my mouth working the man behind Bradley clapped a reassuring hand on his shoulder. "It's all right, Rik—nothing's going to hurt you. Really. This is a good ship, and we're going to be perfectly safe aboard her."

Bradley slowly straightened, and the other man shifted his attention to me. "I'm Dr. Hammerfeld Lanton, Captain," he said, extending his hand. This is Rik Bradley. We're traveling in adjoining cabins."

"Of course," I said, nodding as if I'd already known that. In reality I hadn't had time to check out the passenger lists and assignments, but I could trust Leeds to have set things up properly. "Are you a doctor of medicine, sir?"

"In a way," Lanton said. "I'm a psychiatrist."

"Ah," I said, and managed two or three equally brilliant conversational gems before the two of them moved on. The last three passengers I dispatched with similar polish, and when everyone was inside I sealed the portal and headed for the bridge.

Alana had finished dickering with the tower and was running the prelift computer check when I arrived. "What's the verdict?" I asked as I slid into my chair and keyed for helm check.

"We've still got our lift slot," she said. "That's conditional on Matope getting the elevon system working within the next half hour, of course."

"Idiots," I muttered. The elevons wouldn't be needed until we arrived at Taimyr some six weeks from now, and Matope could practically rebuild them from scratch in that amount of time. To insist they be in prime condition before we could lift was unreasonable even for bureaucrats.

"Oh, there's no problem—Tobbar reported they were closing things up a few minutes ago. They'll put it through its paces, it'll work perfectly, they'll transmit the readout, and that'll be that." She cleared her throat. "Incidentally... are you aware we've got a skull-diver and his patient aboard?"

"Yes; I met—patient?" I interrupted myself as the last part of her sentence registered. "Who?"

"Name's Bradley," she said. "No further data on him, but apparently he and this Lanton character had a fair amount of electronic and medical stuff delivered to their cabins."

A small shiver ran up my back as I remembered Bradley's face. No wonder he'd struck me as strange. "No mention at all of what's wrong—of why Bradley needs a psychiatrist?"

"Nothing. But it can't be anything serious." The test board bleeped, and Alana paused to peer at the results. Apparently satisfied, she keyed in the next test on the check list. "The Swedish Psychiatric Institute seems to be funding the trip, and they presumably know the regulations about notifying us of potential health risks." "Um." On the other hand, a small voice whispered in my ear, if there was some problem with Bradley that made him marginal for space certification, they were more likely to get away with slipping him aboard a tramp than on a liner. "Maybe I should give them a call, anyway. Unless you'd like to?"

I glanced over in time to see her face go stony. "No, thank you," she said firmly.

"Right." I felt ashamed of the comment, not really having meant it the way it had come out. All of us had our own reasons for being where we were; Alana's was an overdose of third-degree emotional burns. She was the type who'd seemingly been born to nurse broken wings and bruised souls, the type who by necessity kept her own heart in full view of both friends and passersby. Eventually, I gathered, one too many of her mended souls had torn out the emotional IVs she'd set up and flown off without so much as a backward glance, and she had renounced the whole business and run off to space. Ice to Europa, I'd thought once; there were enough broken wings out here for a whole shipload of Florence Nightingales. But what I'd expected to be a short vacation for her had become four years' worth of armor plate over her emotions, until I wasn't sure she even knew anymore how to care for people. The last thing in the universe she would be interested in doing would be getting involved in any way with Bradley's problems. "Is all the cargo aboard now?" I asked, to change the subject.

"Yes, and Wilkinson certifies it's properly stowed."

"Good." I got to my feet. "I guess I'll make a quick spot survey of the ship, if you can handle things here."

"Go ahead," she said, not bothering to look up. Nodding anyway, I left.

I stopped first at the service shafts where Matope and Tobbar were just starting their elevon tests, staying long enough to satisfy myself the resulting data were adequate to please even the tower's bit-pickers. Then it was to each of the cargo holds to double-check Wilkinson's stowing arrangement, to the passenger area to make sure all their luggage had been properly brought on board, to the computer room to look into a reported malfunction—a false alarm, fortunately— and finally back to the bridge for the lift itself. Somehow, in all the running around, I never got around to calling Sweden. Not, as I found out later, that it would have done me any good.

—

We lifted right on schedule, shifting from the launch fields grav booster to ramjet at ten kilometers and kicking in the fusion drive as soon as it was legal to do so. Six hours later we were past Luna's orbit and ready for the first cascade maneuver.

Leeds checked in first, reporting officially that the proper number of dosages had been drawn from the sleeper cabinet and were being distributed to the passengers. Pascal gave the okay from the computer room, Matope from the engine room, and Sarojis from the small chamber housing the field generator itself. I had just pulled a hard copy of the computer's course instructions when Leeds called back. "Captain, I'm in Dr. Lanton's cabin," he said without preamble. "Both he and Mr. Bradley refuse to take their sleepers."

Alana turned at that, and I could read my own thought in her face: Lanton and Bradley had to be nuts. "Has Dr. Epstein explained the reasons behind the procedure?" I asked carefully, mindful of both my responsibilities and my limits here.

"Yes, I have," Kate Epsteins clear soprano came. "Dr. Lanton says that his work requires both of them to stay awake through the cascade point."

"Work? What sort of work?"

A pause, and Lanton's voice replaced Kate's. "Captain, this is Dr. Lanton. Rik and I are involved in an experimental type of therapy here. The personal details are confidential, but I assure you that it presents no danger either to us or to you."

Therapy. Great. I could feel anger starting to churn in my gut at Lanton's casual arrogance in neglecting to inform me ahead of time that he had more than transport in mind for my ship. By all rights I should freeze the countdown and sit Lanton down in a corner somewhere until I was convinced everything was as safe as he said. But time was money in this business; and if Lanton was glossing things over he could probably do so in finer detail than I could catch him on, anyway. "Mr. Bradley?" I called. "You agree to pass up your sleeper, as well?"

"Yes, sir," came the mousy voice.

"All right. Dr. Epstein, you and Mr. Leeds can go ahead and finish your rounds."

"Well," Alana said as I flipped off the intercom, "at least if something goes wrong the record will clear us of any fault at the inquest."

"You're a genuine ray of sunshine," I told her sourly. "What else could I have done?"

"Baked Lanton over the coals for some information. We're at least entitled to know what's going on."

"Oh, we'll find out, all right. As soon as we're through the point I'm going to haul Lanton up here for a long, cozy chat." I checked the readouts, cascade point in seventeen minutes. "Look, you might as well go to your cabin and hit the sack. I know it's your turn, but you were up late with that spare parts delivery and you're due some downtime."

She hesitated; wanting to accept, no doubt, but slowed by considerations of duty. "Well... all right. I'm taking the next one, then. I don't know, though; maybe you shouldn't be up here alone. In case Lanton's miscalculated." "You mean if Bradley goes berserk or something?" That thought had been lurking in my mind, too, though it sounded rather ridiculous when spoken out loud. Still... "I can lower the pressure in the passenger deck corridor to half an atmosphere. That'll be enough to lock the doors without triggering any vacuum alarms."

"Leaves Lanton on his own in case of trouble... but I suppose that's okay."

"He's the one who's so sure it's safe. Go on, now—get out of here."

She nodded and headed for the door. She paused there, though, her hand resting on the release. "Don't just haul Lanton away from Bradley when you want to talk to him," she called back over her shoulder. "Try to run into him in the lounge or somewhere instead when he's already alone. It might be hard on Bradley to know you two were off somewhere together talking about him." She slapped the release, almost viciously, and was gone.

I stared after her for a long minute, wondering if I'd actually seen a crack in that heavy armor plate. The bleep of the intercom brought me back to the task at hand, Kate telling me the passengers were all down and that she, Leeds, and Wilkinson had taken their own sleepers. One by one the other six crewers also checked in. Within ten minutes they would be asleep, and I would be in sole charge of my ship.

Twelve minutes to go. Even with the Dancer's old manual setup there was little that needed to be done. I laid the hard copy of the computer's instructions where it would be legible but not in the way, shut down all the external sensors and control surfaces, and put the computer and other electronic equipment into neutral/standby mode. The artificial gravity I left on; I'd tried a cascade point without it once and would never do so again. Then I waited, trying not to think of what was coming... and at the appropriate time I lifted the safety cover and twisted the field generator control knob.

And suddenly there were five of us in the room.

I will never understand how the first person to test the Colloton Drive ever made it past this point. The images silently surrounding me a bare arm's length away were lifesize, lifelike, and—at first glance, anyway—as solid as the panels and chairs they seemed to have displaced. It took a careful look to realize they were actually slightly transparent, like some kind of colored glass, and a little experimentation at that point would show they had less substance than air. They were nothing but ghosts, specters straight out of childhoods scariest stories. Which merely added to the discomfort... because all of them were me.

Five seconds later the second set of images appeared, perfectly aligned with the first. After that they came more and more quickly, as the spacing between them similarly decreased, forming an ever-expanding horizontal cross with me at the center. I watched—forced myself to watch—knew I had to watch—as the lines continued to lengthen, watched until they were so long that I could no longer discern whether any more were being added. I took a long, shuddering breath—peripherally aware that the images nearest me were doing the same—and wiped a shaking hand across my forehead. You don't have to look, I told myself, eyes rigidly fixed on the back of the image in front of me. You've seen it all before. What's the point? But I'd fought this fight before, and I knew in advance I would lose. There was indeed no more point to it than there was to pressing a bruise, but it held an equal degree of compulsion. Bracing myself, I turned my head and gazed down the line of images strung out to my left.

The armchair philosophers may still quibble over what the cascade point images "really" are, but those of us who fly the small ships figured it out long ago. The Colloton field puts us into a different type of space, possibly an entire universe worth of it—that much is established fact. Somehow this space links us into a set of alternate realities, universes that might have been if things had gone differently... and what I was therefore seeing around me were images of what I would be doing in each of those universes.

Sure, the theory has problems. Obviously, I should generate a separate pseudoreality every time I choose ham instead of turkey for lunch, and just as obviously such trivial changes don't make it into the pattern. Only the four images closest to me are ever exactly my doubles; even the next ones in line are noticeably if subtly different. But it's not a matter of subconscious suggestion, either. Too many of the images are... unexpected... for that.

It was no great feat to locate the images I particularly needed to see: the white-and-gold liner captain's uniforms stood out brilliantly among the more dingy jumpsuits and coveralls on either side. Liner captain. In charge of a fully equipped, fully modernized ship; treated with the respect and admiration such a position brought. It could have been—should have been. And to make things worse, I knew the precise decision that had lost it to me.

It had been eight years now since the uniforms had appeared among my cascade images; ten since the day I'd thrown Lord Hendrik's son off the bridge of the training ship and simultaneously guaranteed myself a blackballing with every major company in the business. Could I have handled the situation differently? Probably. Should I have? Given the state of the art then, no. A man who, after three training missions, still went borderline claustrophobic every time he had to stay awake through a cascade point had no business aboard a ship, let alone on its bridge. Hendrik might have forgiven me once he thought things through. The kid, who was forced into a ground position with the firm, never did. Eventually, of course, he took over the business.

I had no way of knowing that four years later the Aker-Ming Autotorque would eliminate the need for anyone to stay awake through cascade maneuvers. I doubt seriously the kid appreciated the irony of it all.

In the eight years since the liner captain uniforms had appeared they had been gradually moving away from me along all four arms of the cross. Five more years, I estimated, and they would be far enough down the line to disappear into the mass of images crowded together out there. Whether my reaction to that event would be relief or sadness I didn't yet know, but there was no doubt in my mind that it would in some way be the end of a chapter in my life. I gazed at the figures for another minute... and then, with my ritual squeezing of the bruise accomplished, I let my eyes drift up and down the rest of the line.

They were unremarkable, for the most part: minor variations in my appearance or clothing. The handful that had once showed me in some nonspacing job had long since vanished toward infinity; I'd been out here a long time. Perhaps too long... a thought the half-dozen or so gaps in each arm of the pattern underlined with unnecessary force. I'd told Bradley that ships like the Dancer rarely crashed, a perfectly true statement; but what I hadn't mentioned was that the chances of simply disappearing en route were something rather higher. None of us liked to think about that, especially during critical operations like cascade point maneuvers. But the gaps in the image pattern were a continual reminder that people still died in space. In six possible realities, apparently, I'd made a decision that killed me.

Taking another deep breath, I forced all of that as far from my mind as I could and activated the Dancer's flywheel.

Even on the bridge the hum was audible as the massive chunk of metal began to spin. A minute later it had reached its top speed... and the entire ship's counter- rotation began to register on the gyroscope set behind glass in the ceiling above my head. The device looked out of place, a decided anachronism among the modern instruments, control circuits, and readouts filling the bridge. But using it was the only way a ship our size could find its way safely through a cascade point. The enhanced electron tunneling effect that fouled up electronic instrument performance was well understood; what was still needed was a way to predict the precise effect a given cascade point rotation would generate. Without such predictability, readings couldn't even be given adjustment factors. Cascade navigation thus had to fall back on gross electrical and purely mechanical systems: flywheel, physical gyroscope, simple on-off controls, and a nonelectronic decision maker. Me. Slowly, the long needle above me crept around its dial. I watched its reflection carefully in the magnifying mirror, a system that allowed me to see the indicator without having to break my neck looking up over my shoulder. Around me, the cascade images did their own slow dance, a strange kaleidoscopic thing that moved the images and gaps around within each branch of the cross, while the branches themselves remained stationary relative to me. The effect was unexplained; but then, Colloton field theory left a lot of things unexplained. Mathematically, the basic idea was relatively straightforward: the space we were in right now could be described by a type of bilinear conformal mapping— specifically, a conjugate inversion that maps lines into circles. From that point it was all downhill, the details tangling into a soup of singularities, branch points, and confluent Riemann surfaces; but what it all eventually boiled down to was that a yaw rotation of the ship here would become a linear translation when I shut down the field generator and we reentered normal space. The Dancer's rotation was coming up on two degrees now, which for the particular configuration we were in meant we were already about half a light-year closer to our destination. Another—I checked the printout—one point three six and I would shut down the flywheel, letting the Dancer's momentum carry her an extra point two degree for a grand total of eight light-years.

The needle crept to the mark, and I threw the flywheel switch, simultaneously giving my full attention over to the gyro. Theoretically, over- or undershooting the mark could be corrected during the next cascade point—or by fiddling the flywheel back and forth now—but it was simpler not to have to correct at all. The need to make sure we were stationary was another matter entirely; if the Dancer were still rotating when I threw the field switch we would wind up strung out along a million kilometers or more of space. I thought of the gaps in my cascade image pattern and shivered.

But that was all the closer death was going to get to me, at least this time. The delicately balanced spin lock worked exactly as it was supposed to, freezing the field switch in place until the ship's rotation was as close to zero as made no difference. I shut off the field and watched my duplicates disappear in reverse order, waiting until the last four vanished before confirming the stars were once again visible through the bridges tiny viewport. I sighed; and fighting the black depression that always seized me at this point, I turned the Dancer's systems back on and set the computer to figuring our exact position. Someday, I thought, I'd be able to afford to buy Aker-Ming Autotorques and never, never have to go through this again.

And someday I'd swim the Pacific Ocean, too.

Slumping back in my chair, I waited for the computer to finish its job and allowed the tears to flow.

—

Crying, for me, has always been the simplest and fastest way of draining off tension, and I've always felt a little sorry for men who weren't able to appreciate its advantages. This time was no exception, and I was feeling almost back to normal by the time the computer produced its location figures. I was still poring over them twenty minutes later when Alana returned to the bridge. "Another cascade point successfully hurdled, I see," she commented tiredly. "Hurray for our side."

"I thought you were supposed to be taking a real nap, not just a sleeper's worth," I growled at her over my shoulder.

"I woke up and decided to take a walk," she answered, her voice suddenly businesslike. "What's wrong?"

I handed her a printout, pointed to the underlined numbers. "The gyroscope reading says we're theoretically dead on position. The stars say we're short."

"Wumph!" Frowning intently at the paper, she kicked around the other chair and sat down. "Twenty light-days. That's what, twice the expected error for this point? Great. You double-checked everything, of course?"

"Triple-checked. The computer confirmed the gyro reading, and the astrogate program's got positive ident on twenty stars. Margin of errors no greater than ten light-minutes on either of those."

"Yeah." She eyed me over the pages. "Anything funny in the cargo?"

I gestured to the manifest in front of me. "We've got three boxes of technical equipment that include Ming metal," I said. "All three are in the shield. I checked that before we lifted."

"Maybe the shields sprung a leak," she suggested doubtfully.

"It's supposed to take a hell of a break before the stuff inside can affect cascade point configuration."

"I can go check if you'd like."

"No, don't bother. There's no rush now, and Wilkinson's had more experience with shield boxes. He can take a look when he wakes up. I'd rather you stay here and help me do a complete programming check. Unless you'd like to obey orders and go back to bed."

She smiled faintly. "No, thanks; I'll stay. Um... I could even start things alone if you'd like to go to the lounge for a while."

"I'm fine," I growled, irritated by the suggestion.

"I know," she said. "But Lanton was down there alone when I passed by on my way here."

I'd completely forgotten about Lanton and Bradley, and it took a couple of beats for me to catch on. Cross-examining a man in the middle of cascade depression wasn't a terrifically nice thing to do, but I wasn't feeling terrifically nice at the moment. "Start with the astrogate program," I told Alana, getting to my feet. "Give me a shout if you find anything."

Lanton was still alone in the lounge when I arrived. "Doctor," I nodded to him as I sat down in the chair across from his. "How are you feeling?" The question was more for politeness than information; the four empty glasses on the end table beside him and the half-full one in his hand showed how he'd chosen to deal with his depression. I'd learned long ago that crying was easier on the liver.

He managed a weak smile. "Better, Captain; much better. I was starting to think I was the only one left on the ship."

"You're not even the only one awake," I said. "The other passengers will be wandering in shortly—you people get a higher-dose sleeper than the crew takes."

He shook his head. "Lord, but that was weird. No wonder you want everyone to sleep through it. I can't remember the last time I felt this rotten." "It'll pass," I assured him. "How did Mr. Bradley take it?"

"Oh, fine. Much better than I did, though he fell apart just as badly when it was over. I gave him a sedative—the coward's way out, but I wasn't up to more demanding therapy at the moment."

So Bradley wasn't going to be walking in on us any time soon. Good. "Speaking of therapy, Doctor, I think you owe me a little more information about what you're doing."

He nodded and took a swallow from his glass. "Beginning, I suppose, with what exactly Rik is suffering from?"

"That would be nice," I said, vaguely surprised at how civil I was being. Somehow, the sight of Lanton huddled miserably with his liquor had taken all the starch out of my fire-and-brimstone mood. Alana was clearly having a bad effect on me.

"Okay. Well, first and foremost, he is not in any way dangerous, either to himself or other people. He has no tendencies even remotely suicidal or homicidal. He's simply... permanently disoriented, I suppose, is one way to think of it. His personality seems to slide around in strange ways, generating odd fluctuations in behavior and perception."

Explaining psychiatric concepts in layman's terms obviously wasn't Lanton's forte. "You mean he's schizophrenic? Or paranoid?" I added, remembering our launch-field conversation.

"Yes and no. He shows some of the symptoms of both—along with those of five or six other maladies—but he doesn't demonstrate the proper biochemical syndrome for any known mental disease. He's a fascinating, scientifically annoying anomaly. I've got whole bubble-packs of data on him, taken over the past five years, and I'm convinced I'm teetering on the edge of a breakthrough. But I've already exhausted all the standard ways of probing a patient's subconscious, and I had to come up with something new." He gestured around him. "This is it."

"This is what? A new form of shock therapy?"

"No, no—you're missing the point. I'm studying Rik's cascade images."

I stared at him for a long moment. Then, getting to my feet, I went to the autobar and drew myself a lager. "With all due respect," I said as I sat down again, "I think you're out of your mind. First of all, the images aren't a product of the deep subconscious or whatever; they're reflections of universes that might have been."

"Perhaps. There is some argument about that." He held up a hand as I started to object. "But either way, you have to admit that your conscious or unconscious mind must have an influence on them. Invariably, the images that appear show the results of major decisions or events in one's life; never the plethora of insignificant choices we all make. Whether the subconscious is choosing among actual images or generating them by itself, it is involved with them and therefore can be studied through them."

He seemed to settle slightly in his chair, and I got the feeling this wasn't the first time he'd made that speech. "Even if I grant you all that," I said, "which I'm not sure I do, I think you're running an incredibly stupid risk that the cascade point effects will give Bradley a shove right over the edge. They're hard enough on those of us who haven't got psychological problems—what am I telling you this for? You saw what it was like, damn it. The last thing I want on my ship is someone who's going to need either complete sedation or a restraint couch all the way to Taimyr!"

I stopped short, suddenly aware that my volume had been steadily increasing. "Sorry," I muttered, draining half of my lager. "Like I said, cascade points are hard on all of us."

He frowned. "What do you mean? You were asleep with everyone else, weren't you?"

"Somebody's got to be awake to handle the maneuver," I said.

"But... I thought there were autopilots for cascade points now."

"Sure—the Aker-Ming Autotorque. But they cost nearly twenty-two thousand apiece and have to be replaced every hundred cascade points or so. The big liners and freighters can afford luxuries like that; tramp starmers can't."

"I'm sorry—I didn't know." His expression suggested he was also sorry he hadn't investigated the matter more thoroughly before booking aboard the Dancer.

I'd seen that look on people before, and I always hated it. "Don't worry; you're perfectly safe. The manual method's been used for nearly two centuries, and my crew and I know what we're doing."

His mind was obviously still a half kilometer back. "But how can it be that expensive? I mean, Ming metal's an exotic alloy, sure, but it's only selenium with a little bit of rhenium, after all. You can buy psy-test equipment with Ming-metal parts for a fraction of the cost you quoted."

"And we've got an entire box made of the stuff in our number one cargo hold," I countered. "But making a consistent-property rotation gauge is a good deal harder than rolling sheets or whatever. Anyway, you're evading my question. What are you going to do if Bradley can't take the strain?"

He shrugged, but I could see he didn't take the possibility seriously. "If worst comes to worst, I suppose I could let him sleep while I stayed awake to observe his images. They do show up even in your sleep, don't they?"

"So I've heard." I didn't add that I'd feel like a voyeur doing something like that. Psychiatrists, accustomed to poking into other people's minds, clearly had different standards than I did. "Good. Though that would add another variable," he added thoughtfully. "Well... I think Rik can handle it. We'll do it conscious as long as we can."

"And what's going to be your clue that he's not handling it? The first time he tries to strangle one of his images? Or maybe when he goes catatonic?"

He gave me an irritated look. "Captain, I am a psychiatrist. I'm perfectly capable of reading my patient and picking up any signs of trouble before they become serious. Rik is going to be all right; let's just leave it at that."

I had no intention of leaving it at that; but just then two more of the passengers wandered into the lounge, so I nodded to Lanton and left. We had five days before the next cascade point, and there would be other opportunities in that time to discuss the issue. If necessary, I would manufacture them.

—

Alana had only negatives for me when I got back to the bridge. "The astrogate's clean," she told me. "I've pulled a hard copy of the program to check, but the odds that a glitch developed that just happened to look reasonable enough to fool the diagnostic are essentially nil." She waved at the long gyroscope needle above us. "Computer further says the vacuum in the gyro chamber stayed hard throughout the maneuver and that there was no malfunction of the mag-bearing fields."

So the gyroscope hadn't been jinxed by friction into giving a false reading. Combined with the results on the astrogate program, that left damn few places to look. "Has Wilkinson checked in?"

"Yes, and I've got him testing the shield for breaks."

"Good. I'll go down and give him a hand. Have you had time to check out our current course?"

"Not in detail, but the settings look all right to me."

"They did to me, too, but if there's any chance the computer's developed problems we can't take anything for granted. I don't want to be in the wrong position when it's time for the next point."

"Yeah. Well, Pascal's due up here in ten minutes. I guess the astrogate deep- check can wait until then. What did you find out from Lanton?"

With an effort I switched gears. "According to him, Bradley's not going to be any trouble. He sounds more neurotic than psychotic, from Lanton's description, at least at the moment. Unfortunately, Lanton's got this great plan to use cascade images as a research tool, and intends to keep Bradley awake through every point between here and Taimyr."

"He what? I don't suppose he's bothered to consider what that might do to Bradley's problems?"

"That's what I wanted to know. I never did get an acceptable answer." I moved to the bridge door, poked the release. "Don't worry, we'll pound some sense into him before the next point. See you later."

Wilkinson and Sarojis were both in the number one hold when I arrived, Sarojis offering minor assistance and lots of suggestions as Wilkinson crawled over the shimmery metal box that took up the forward third of the narrow space. Looking down at me as I threaded my way between the other boxes cramming the hold, he shook his head. "Nothing wrong here, Cap'n," he said. "The shields structurally sound; there's no way the Ming metal inside could affect our configuration."

"No chance of hairline cracks?" I asked.

He held up the detector he'd been using. "I'm checking, but nothing that small would do anything."

I nodded acknowledgement and spent a moment frowning at the box. Ming metal had a number of unique properties inside cascade points, properties that made it both a blessing and a curse to those of us who had to fly with it. Its unique blessing, of course, was that its electrical, magnetic, and thermodynamic properties were affected only by the absolute angle the ship rotated through, and not by any of the hundred or so other variables in a given cascade maneuver. It was this predictability that finally had made it possible for a cascade point autodrive mechanism to be developed. Of more concern to smaller ships like mine, though, was that Ming metal drastically changed a ship's "configuration"—the size, shape, velocity profile, and so on from which the relation between rotation angle and distance traveled on a given maneuver could be computed. Fortunately, the effect was somewhat analogous to air resistance, in that if one piece of Ming metal were completely enclosed in another, only the outer container's shape, size, and mass would affect the configuration. Hence, the shield. But if it hadn't been breached, then the cargo inside it couldn't have fouled us up.... "What are the chances," I asked Wilkinson, "that one of these other boxes contains Ming metal?"

"Without listing it on the manifest?" Sarojis piped up indignantly. He was a dark, intense little man who always seemed loudly astonished whenever anyone did anything either unjust or stupid. Most everyone on the Dancer OD'd periodically on his chatter and spent every third day or so avoiding him. Alana and Wilkinson were the only exceptions I knew of, and even Alana got tired of him every so often. "They couldn't do that," Sarojis continued before I could respond. "We could sue them into bankruptcy."

"Only if we make it to Taimyr," I said briefly, my eyes on Wilkinson.

"One way to find out," he returned. Dropping lightly off the shield, he replaced his detector in the open tool box lying on the deck and withdrew a wandlike gadget.

It took two hours to run the wand over every crate in the Dancer's three holds, and we came up with precisely nothing. "Maybe one of the passengers brought some aboard," Sarojis suggested.

"You've got to be richer than any of our customers to buy cases with Ming- metal buckles." Wilkinson shook his head. "Cap'n, it's got to be a computer fault, or else something in the gyro."

"Um," I said noncommittally. I hadn't yet told them that I'd checked with Alana midway through all the cargo testing and that she and Pascal had found nothing wrong in their deep-checks of both systems. There was no point in worrying them more than necessary.

I returned to the bridge to find Pascal there alone, slouching in the helm chair and gazing at the displays with a dreamy sort of expression on his face. "Where's Alana?" I asked him, dropping into the other chair and eyeing the pile of diagnostic printouts they'd thoughtfully left for me. "Finally gone to bed?"

"She said she was going to stop by the dining room first and have some dinner," Pascal said, the dreamy expression fading somewhat. "Something about meeting the passengers."

I glanced at my watch, realizing with a start that it was indeed dinnertime. "Maybe I'll go on down, too. Any problems here, first?"

He shook his head. "I have a theory about the cascade point error," he said, lowering his voice conspiratorially. "I'd rather not say what it is, though, until I've had more time to think about it."

"Sure," I said, and left. Pascal fancied himself a great scientific detective and was always coming up with complex and wholly unrealistic theories in areas far outside his field, with predictable results. Still, nothing he'd ever come up with had been actually dangerous, and there was always the chance he would someday hit on something useful. I hoped this would be the day.

The Dancer's compact dining room was surprisingly crowded for so soon after the first cascade point, but a quick scan of the faces showed me why. Only nine of our twelve passengers had made it out of bed after their first experience with sleepers, but their absence was more than made up for by the six crewers who had opted to eat here tonight instead of in the duty mess. The entire off-duty contingent... and it wasn't hard to figure out why.

Bradley, seated between Lanton and Tobbar at one of the two tables, was speaking earnestly as I slipped through the door. "...less symbolic than it was an attempt to portray the world from a truly alien viewpoint, a viewpoint he would change every few years. Thus A Midsummer Wedding has both the slight fish-eye distortion and the color shifts you might get from a water-dwelling creature; also the subtleties of posture and expression that such an alien wouldn't understand and might therefore not get right."

"But isn't strange sensory expression one of the basic foundations of art?" That was Tobbar—so glib on any topic that you were never quite sure whether he actually knew anything about it or not. "Drawing both eyes on one side of the head, putting nudes at otherwise normal picnics—that sort of thing."

"True, but you mustn't confuse weirdness for its own sake with the consistent, scientifically accurate variations Meyerhaus used."

There was more, but just then Alana caught my eye from her place at the other table and indicated the empty seat next to her. I went over and sat down, losing the train of Bradley's monologue in the process. "Anything?" she whispered to me.

"A very flat zero," I told her.

She nodded once but didn't say anything, and I noticed her gaze drift back to Bradley. "Knows a lot about art, I see," I commented, oddly irritated by her shift in attention.

"You missed his talk on history," she said. "He got quite a discussion going over there—that mathematician, Dr. Chileogu, also seems to be a history buff. First time I've ever seen Tobbar completely frozen out of a discussion. He certainly seems normal enough."

"Tobbar?"

"Bradley."

"Oh." I looked over at Bradley, who was now listening intently to someone holding forth from the other end of his table. Permanently disoriented, Lanton had described him. Was he envisioning himself a professor of art or something right now? Or were his delusions that complete? I didn't know; and at the moment I didn't care. "Well, good for him. Now if you'd care to bring your mind back to ship's business, we still have a problem on our hands."

Alana turned back to me, a slight furrow across her forehead. "I'm open to suggestions," she said. "I was under the impression that we were stuck for the moment."

I clenched my jaw tightly over the retort that wanted to come out. We were stuck; and until someone else came up with an idea there really wasn't any reason why Alana shouldn't be down here relaxing. "Yeah," I growled, getting to my feet. "Well, keep thinking about it."

"Aren't you going to eat?"

"I'll get something later in the duty mess," I said.

I paused at the door and glanced back. Already her attention was back on Bradley. Heading back upstairs to the duty mess, I programmed myself an unimaginative meal that went down like so much wet cardboard. Afterwards, I went back to my cabin and pulled a tape on cascade point theory. I was still paging through it two hours later when I fell asleep.

—

I tried several times in the next five days to run into Lanton on his own, but it seemed that every time I saw him Bradley was tagging along like a well-behaved cocker spaniel. Eventually, I was forced to accept Alana's suggestion that she and Tobbar offer Bradley a tour of the ship, giving me a chance to waylay Lanton in the corridor outside his cabin. The psychiatrist seemed preoccupied and a little annoyed at being so accosted, but I didn't let it bother me.

"No, of course there's no progress yet," he said in response to my question. "I also didn't expect any. The first cascade point observations were my baseline. I'll be asking questions during the next one, and after that I'll start introducing various treatment techniques and observing Rik's reactions to them."

He started to slide past me, but I moved to block him. "Treatment? You never said anything about treatment."

"I didn't think I had to. I am legally authorized to administer drugs and such, after all."

"Maybe on the ground," I told him stiffly. "But out here the ship's doctor is the final medical authority. You will not give Bradley any drugs or electronic treatment without first clearing it with Dr. Epstein." Something tugged at my mind, but I couldn't be bothered with tracking it down. "As a matter of fact, I want you to give her a complete list of all the drugs you've brought aboard before the next cascade point. Anything addictive or potentially dangerous is to be turned over to her for storage in the sleeper cabinet Understand?"

Lanton's expression stuck somewhere between irritated and stunned. "Oh, come on, Captain, be reasonable—practically every medicine in the book can be dangerous if taken in excessive doses." His face seemed to recover, settling into a bland sort of neutral as his voice similarly adjusted to match it. "Why do you object so strongly to what I'm trying to do for Rik?"

"I'd hurry with that list, Doctor—the next points scheduled for tomorrow. Good day." Spinning on my heel, I turned and stalked away.

I called back Kate Epstein as soon as I reached my cabin and told her about the list Lanton would be delivering to her. I got the impression that she, too, thought I was overreacting, but she nevertheless agreed to cooperate. I extracted a promise to keep me informed on what Lanton's work involved, then signed off and returned once more to the Colloton theory tapes that had occupied the bulk of my time the past four days.

But despite the urgency I was feeling—we had less than twenty hours to the next cascade point—the words on my reader screen refused to coalesce into anything that made sense. I gritted my teeth and kept at it until I discovered myself reading the same paragraph for the fourth time and still not getting a word of it. Snapping off my reader in disgust, I stretched out on my bed and tried to track down the source of my distraction.

Obviously, my irritation at Lanton was a good fraction of it. Along with the high-handed way he treated the whole business of Bradley, he'd now added the insult of talking to me in a tone of voice that implied I needed his professional services—and for nothing worse than insisting on my rights as captain of the Dancer. I wished to hell I'd paid more attention to the passenger manifest before I'd let the two of them aboard. Next time I'd know better.

Still... I had to admit that maybe I had overreacted a bit. But it wasn't as if I was being short-tempered without reason. I had plenty of reasons to be worried; Lanton's game of cascade image tag and its possible effects on Bradley, the still- unexplained discrepancy in the last points maneuvers, the changes I was seeing in Alana—

Alana. Up until that moment I hadn't consciously admitted to myself that she was behaving any differently than usual. But I hadn't flown with her for four years without knowing all of her moods and tendencies, and it was abundantly clear to me that she was slowly getting involved with Bradley.

My anger over such an unexpected turn of events was not in any way motivated by jealousy. Alana was her own woman, and any part of her life not directly related to her duties was none of my business. But I knew that, in this case, her involvement was more than likely her old affinity for broken wings, rising like the phoenix—except that the burning would come afterwards instead of beforehand. I didn't want to see Alana go through that again, especially with someone whose presence I felt responsible for. There was, of course, little I could do directly without risking Alana's notice and probable anger; but I could let Lanton know how I felt by continuing to make things as difficult as possible. And I would.

And with that settled, I managed to push it aside and return to my studies. It is, I suppose, revealing that it never occurred to me at the time how inconsistent my conclusion and proposed course of action really were. After all, the faster Lanton cured Bradley, the faster the broken-wing attraction would disappear and— presumably—the easier Alana would be able to extricate herself. Perhaps, even then, I was secretly starting to wonder if her attraction to him was something more than altruistic.

—

"Two minutes," Alana said crisply from my right, her tone almost but not quite covering the tension I knew she must be feeling. "Gyro checks out perfectly."

I made a minor adjustment in my mirror, confirmed that the long needle was set dead on zero. Behind the mirror, the displays stared blankly at me from the control board, their systems having long since been shut down. I looked at the computer's printout, the field generator control cover, my own hands—anything to keep from looking at Alana. Like me, she was unaccustomed to company during a cascade point, and I was determined to give her what little privacy I could.

"One minute," she said. "You sure we made up enough distance for this to be safe?"

"Positive. The only possible trouble could have come from Epsilon Eridani, and we've made up enough lateral distance to put it the requisite six degrees off our path."

"Do you suppose that could have been the trouble last time? Could we have come too close to something—a black dwarf, maybe, that drifted into our corridor?"

I shrugged, eyes on the clock. "Not according to the charts. Ships have been going to Taimyr a long time, you know, and the whole route's been pretty thoroughly checked out. Even black dwarfs have to come from somewhere." Gritting my teeth, I flipped the cover off the knob. "Brace yourself; here we go."

Doing a cascade point alone invites introspection, memories of times long past, and melancholy. Doing it with someone else adds instant vertigo and claustrophobia to the list. Alana's images and mine still appeared in the usual horizontal cross shape, but since we weren't seated facing exactly the same direction, they didn't overlap. The result was a suffocatingly crowded bridge— crowded, to make things worse, with images that were no longer tied to your own motions, but would twitch and jerk apparently on their own.

For me, the disadvantages far outweighed the single benefit of having someone there to talk to, but in this case I had had little choice. Alana had steadfastly refused to let me take over from her on two points in a row, and I'd been equally insistent on being awake to watch the proceedings. It was a lousy compromise, but I'd known better than to order Alana off the bridge. She had her pride too.

"Activating flywheel."

Alana's voice brought my mind back to business. I checked the printout one last time, then turned my full attention to the gyro needle. A moment later it began its slow creep, and the dual set of cascade images started into their own convoluted dances. Swallowing hard, I gave my stomach stern orders and held on.

It seemed at times to be lasting forever, but finally it was over. The Dancer had been rotated, had been brought to a stop, and had successfully made the transition to real space. I slumped in my seat, feeling a mixture of cascade depression and only marginally decreased tension. The astrogate program's verdict, after all, was still to come.

But I was spared the ordeal of waiting with twiddled thumbs for the computer. Alana had barely gotten the ship's systems going again when the intercom bleeped at me. "Bridge," I answered. "This is Dr. Lanton," the tight response came. "There's something very wrong with the power supply to my cabin—one of my instruments just burned out on me."

"Is it on fire?" I asked sharply, eyes flicking to the status display. Nothing there indicated any problem.

"Oh, no—there was just a little smoke and that's gone now. But the thing's ruined."

"Well, I'm sorry, Doctor," I said, trying to sound like I meant it. "But I can't be responsible for damage to electronics that are left running through a cascade point. Even something as simple as an AC power line can show small voltage fluc—oh, damn it!"

Alana jerked at my exclamation. "What—"

"Lanton!" I snapped, already halfway out of my seat. "Stay put and don't touch anything. I'm coming down."

His reply was more question than acknowledgment, but I ignored it. "Alana," I called to her, "call Wilkinson and have him meet me at Lanton's cabin—and tell him to bring a Ming-metal detector."

I caught just a glimpse of her suddenly horrified expression before the door slid shut and I went running down the corridor. There was no reason to run, but I did so anyway.

It was there, of course: a nice, neat Ming-metal dual crossover coil, smack in the center of the ruined neural tracer. At least it had been neat; now it was stained with a sticky goo that had dripped onto it from the blackened circuit board above. "Make sure none of it melted off onto something else," I told Wilkinson as he carefully removed the coil. "If it has we'll either have to gut the machine or find a way to squeeze it inside the shield." He nodded and I stepped over to where Lanton was sitting, the white-hot anger inside me completely overriding my usual depression. "What the hell did you think you were doing, bringing that damn thing aboard?" I thundered, dimly aware that the freshly sedated Bradley might hear me from the next cabin but not giving a damn.

His voice, when he answered, was low and artificially calm—whether in stunned reaction to my rage or simply a reflexive habit I didn't know. "I'm very sorry, Captain, but I swear I didn't know the tracer had any Ming metal in it."

"Why not? You told me yourself you could buy things with Ming-metal parts." And I'd let that fact sail blithely by me, a blunder on my part that was probably fueling ninety percent of my anger.

"But I never see the manufacturing specs on anything I use," he said. "It all comes through the Institute's receiving department, and all I get are the operating manuals and such." His eyes flicked to his machine as if he were going to object to Wilkinson's manhandling of it. "I guess they must have removed any identification tags, as well."

"I guess they must have," I ground out. Wilkinson had the coil out now, and I watched as he laid it aside and picked up the detector wand again. A minute later he shook his head.

"Clean, Cap'n," he told me, picking up the coil again. "I'll take this one to One Hold and put it away."

I nodded and he left. Gesturing to the other gadgets spread around the room, I asked, "Is this all you've got, or is there more in Bradley's cabin?"

"No, this is it," Lanton assured me.

"What about your stereovision camera? I know some of those have Ming metal in them."

He frowned. "I don't have any cameras. Who told you I did?"

"I—" I frowned in turn. "You said you were studying Bradley's cascade images."

"Yes, but you can't take pictures of them. They don't register on any kind of film."

I opened my mouth, closed it again. I was sure I'd known that once, but after years of watching the images I'd apparently clean forgotten it. They were so lifelike... and I was perhaps getting old. "I assumed someone had come up with a technique that worked," I said stiffly, acutely aware that my attempt to save face wasn't fooling either of us. "How do you do it, then?"

"I memorize all of it, of course. Psychiatrists have to have good memories, you know, and there are several drugs that can enhance one's basic abilities."

I'd heard of mnemonic drugs. They were safe, extremely effective, and cost a small fortune. "Do you have any of them with you? If so, I'm going to insist they be locked away."

He shook his head. "I was given a six-month treatment at the Institute before we left. That's the main reason we're on your ship, by the way, instead of something specially chartered. Mnemonic drugs play havoc with otherwise reasonable budgets."

He was making a joke, of course, but it was an exceedingly tasteless one, and the anger that had been draining out of me reversed its flow. No one needed to remind me that the Dancer wasn't up to the Cunard line's standards. "My sympathies to your budget," I said briefly. Turning away, I strode to the door.

"Wait a minute," he called after me. "What are my chances of getting that neural tracer fixed?"

I glanced back over my shoulder. "That probably depends on how good you are with a screwdriver and solder gun," I said, and left.

Alana was over her own cascade depression by the time I returned to the bridge. "I was right," I said as I dropped into my seat. "One of the damned black boxes had a Ming-metal coil."

"I know; Wilkinson called from One Hold." She glanced sideways at me. "I hope you didn't chew Lanton out in front of Bradley."

"Why not?"

"Did you?"

"As it happens, no. Lanton sedated him right after the point again. Why does it matter?"

"Well..." She seemed embarrassed. "It might... upset him to see you angry. You see, he sort of looks up to you—captain of a star ship and all—"

"Captain of a struggling tramp," I corrected her more harshly than was necessary. "Or didn't you bother to tell him that we're the absolute bottom of the line?"

"I told him," she said steadily. "But he doesn't see things that way. Even in five days aboard he's had a glimpse of how demanding this kind of life is. He's never been able to hold down a good job himself for very long, and that adds to the awe he feels for all of us."

"I can tell he's got a lot to learn about the universe," I snorted. For some reason the conversation was making me nervous, and I hurried to bring it back to safer regions. "Did your concern for Bradley's idealism leave you enough time to run the astrogate?"

She actually blushed, the first time in years I'd seen her do that. "Yes," she said stiffly. "We're about thirty-two light-days short this time."

"Damn." I hammered the edge of the control board once with my clenched fist, and then began punching computer keys.

"I've already checked that," Alana spoke up. "We'll dig pretty deep into our fuel reserve if we try to make it up through normal space."

I nodded, my fingers coming to a halt. My insistence on maintaining a high fuel reserve was one of the last remnants of Lord Hendrik's training that I still held onto, and despite occasional ribbing from other freighter captains I felt it was a safety precaution worth taking. The alternative to using it, though, wasn't especially pleasant. "All right," I sighed. "Let's clear out enough room for the computer to refigure our course profile. If possible, I'd like to tack the extra fifty light-days onto one of the existing points instead of adding a new one."

She nodded and started typing away at her console as I called down to the engine room to alert Matope. It was a semimajor pain, but the Dancer's computer didn't have enough memory space to handle the horribly complex Colloton calculations we needed while all the standard operations programming was in place. We would need to shift all but the most critical functions to Matope's manual control, replacing the erased programs later from Pascal's set of master tapes.

It took nearly an hour to get the results, but they turned out to be worth the wait. Not only could we make up our shortfall without an extra point, but with the slightly different stellar configuration we faced now it was going to be possible to actually shorten the duration of one of the points further down the line. That was good news from both practical and psychological considerations. Though I've never been able to prove it, I've long believed that the deepest depressions follow the longest points.

I didn't see any more of Lanton that day, though I heard later that he and Bradley had mingled with the passengers as they always did, Lanton behaving as if nothing at all had happened. Though I knew my crew wasn't likely to go around blabbing about Lanton's Ming-metal blunder, I issued an order anyway to keep the whole matter quiet. It wasn't to save Lanton any embarrassment—that much I was certain of—but beyond that my motives became uncomfortably fuzzy. I finally decided I was doing it for Alana, to keep her from having to explain to Bradley what an idiot his therapist was.

—

The next point, six days later, went flawlessly, and life aboard ship finally settled into the usual deep-space routine. Alana, Pascal, and I each took eight-hour shifts on the bridge; Matope, Tobbar, and Sarojis did the same back in the engine room; and Kate Epstein, Leeds, and Wilkinson took turns catering to the occasional whims of our passengers. Off duty, most of the crewers also made an effort to spend at least a little time in the passenger lounge, recognizing the need to be friendly in the part of our business that was mainly word of mouth. Since that first night, though, the exaggerated interest in Bradley the Mental Patient had pretty well evaporated, leaving him as just another passenger in nearly everyone's eyes.

The exception, of course, was Alana.

In some ways, watching her during those weeks was roughly akin to watching a baby bird hacking its way out of its shell. Alana's bridge shift followed mine, and I was often more or less forced to hang around for an hour or so listening to her talk about her day. Forced is perhaps the wrong word; obviously, no one was nailing me to my chair. And yet, in another sense, I really did have no choice. To the best of my knowledge, I was Alana's only real confidant aboard the Dancer, and to have refused to listen would have deprived her of her only verbal sounding board. And the more I listened, the more I realized how vital my participation really was... because along with the usual rolls, pitches, and yaws of every embryo relationship, this one had an extra complication: Bradley's personality was beginning to change.

Lanton had said he was on the verge of a breakthrough, but it had never occurred to me that he might be able to begin genuine treatment aboard ship, let alone that any of its effects would show up en route. But even to me, who saw Bradley for maybe ten minutes at a time three times a week, the changes were obvious. All the conflicting signals in posture and expression that had bothered me so much at our first meeting diminished steadily until they were virtually gone, showing up only on brief occasions. At the same time, his self-confidence began to increase, and a heretofore unnoticed—by me, at least—sense of humor began to manifest itself. The latter effect bothered me, until Alana explained that a proper sense of humor required both a sense of dignity and an ability to take oneself less than seriously, neither of which Bradley had ever had before. I was duly pleased for her at the progress this showed; privately, I sought out Lanton to find out exactly what he was doing to his patient and the possible hazards thereof. The interview was easy to obtain—Bradley was soloing quite a bit these days—but relatively uninformative. Lanton tossed around a lot of stuff about synaptic fixing and duplicate messenger chemistry, but with visions of a Nobel Prize almost visibly orbiting his head he was in no mood to worry about dangerous side effects. He assured me that nothing he was using was in the slightest way experimental, and that I should go back to flying the Dancer and let him worry about Bradley. Or words to that effect.

I really was happy for Bradley, of course, but the fact remained that his rapid improvement was playing havoc with Alana's feelings. After years away from the wing-mending business she felt herself painfully rusty at it; and as Bradley continued to get better despite that, she began to wonder out loud whether she was doing any good, and if not, what right she had to continue hanging around him. At first I thought this was just an effort to hide the growth of other feelings from me, but gradually I began to realize that she was as confused as she sounded about what was happening. Never before in her life, I gathered, had romantic feelings come to her without the framework of a broken-wing operation to both build on and help disguise, and with that scaffolding falling apart around her she was either unable or unwilling to admit to herself what was really going on.

I felt pretty rotten having to sit around watching her flounder, but until she was able to recognize for herself what was happening there wasn't much I could do except listen. I wasn't about to offer any suggestions, especially since I didn't believe in love at first sight in the first place. My only consolation was that Bradley and Lanton were riding round trip with us, which meant that Alana wouldn't have to deal with any sort of separation crisis until we were back on Earth. I'd never had much sympathy for people who expected time to solve all their problems for them, but in this case I couldn't think of anything better to do.

And so matters stood as we went through our eighth and final point and emerged barely eight hundred thousand kilometers from the thriving colony world Taimyr... and found it deserted. —

"Still nothing," Alana said tightly, her voice reflecting both the remnants of cascade depression and the shock of our impossible discovery. "No response to our call; nothing on any frequency I can pick up. I can't even find the comm satellites' lock signal."

I nodded, my eyes on the scope screen as the Dancer's telescope slowly scanned Taimyr's dark side. No lights showed anywhere. Shifting the aim, I began searching for the nine comm and nav satellites that should be circling the planet. "Alana, call up the astrogate again and find out what it's giving as position uncertainty."

"If you're thinking we're in the wrong system, forget it," she said as she tapped keys.

"Just cheeking all possibilities," I muttered. The satellites, too, were gone. I leaned back in my seat and bit at my lip.

"Yeah. Well, from eighteen positively identified stars we've got an error of no more than half a light-hour." She swiveled to face me and I saw the fear starting to grow behind her eyes. "Pall, what is going on here? Two hundred million people can't just disappear without a trace."

I shrugged helplessly. "A nuclear war could do it, I suppose, and might account for the satellites being gone as well. But there's no reason why anyone on Taimyr should have any nuclear weapons." Leaning forward again, I activated the helm. "A better view might help. If there's been some kind of war the major cities should now be big craters surrounded by rubble. I'm going to take us in and see what the day side looks like from high orbit."

"Do you think that's safe? I mean—" She hesitated. "Suppose the attack came from outside Taimyr?"

"What, you mean like an invasion?" I shook my head. "Even if there are alien intelligences somewhere who would want to invade us, we stand just as good a chance of getting away from orbit as we do from here."

"All right," she sighed. "But I'm setting up a cascade point maneuver, just in case. Do you think we should alert everybody yet?"

"Crewers, yes; passengers, no. I don't want any silly questions until I'm ready to answer them."

We took our time approaching Taimyr, but caution turned out to be unnecessary. No ships, human or otherwise, waited in orbit for us; no one hailed or shot at us; and as I turned the telescope planetward I saw no signs of warfare.

Nor did I see any cities, farmland, factories, or vehicles. It was as if Taimyr the colony had never existed.

"It doesn't make any sense," Matope said after I'd explained things over the crew intercom hookup. "How could a whole colony disappear?"

"I've looked up the records we've got on Taimyr," Pascal spoke up. "Some of the tropical vegetation is pretty fierce in the growth department. If everyone down there was killed by a plague or something, it's possible the plants have overgrown everything."

"Except that most of the cities are in temperate regions," I said shortly, "and two are smack in the middle of deserts. I can't find any of those, either."

"Hmm," Pascal said and fell silent, probably already hard at work on a new theory.

"Captain, you don't intend to land, do you?" Sarojis asked. "If launch facilities are gone and not merely covered over we'd be unable to lift again to orbit."

"I'm aware of that, and I have no intention of landing," I assured him. "But something's happened down there, and I'd like to get back to Earth with at least some idea of what."

"Maybe nothing's happened to the colony," Wilkinson said slowly. "Maybe something's happened to us."

"Such as?"

"Well... this may sound strange, but suppose we've somehow gone back in time, back to before the colony was started."

"That's crazy," Sarojis scoffed before I could say anything. "How could we possibly do something like that?"

"Malfunction of the field generator, maybe?" Wilkinson suggested. "There's a lot we don't know about Colloton space."

"It doesn't send ships back in—"

"All right, ease up," I told Sarojis. Beside me Alana snorted suddenly and reached for her keyboard. "I agree the idea sounds crazy, but whole cities don't just walk off, either," I continued. "It's not like there's a calendar we can look at out here, either. If we were a hundred years in the past, how would we know it?"

"Check the star positions," Matope offered.

"No good; the astrogate program would have noticed if anything was too far out of place. But I expect that still leaves us a possible century or more to rattle around in." "No, it doesn't." Alana turned back to me with a grimly satisfied look on her face. "I've just taken signals from three pulsars. Compensating for our distance from Earth gives the proper rates for all three."

"Any comments on that?" I asked, not expecting any. Pulsar signals occasionally break their normal pattern and suddenly increase their pulse frequency, but it was unlikely to have happened in three of the beasts simultaneously; and in the absence of such a glitch the steady decrease in frequency was as good a calendar as we could expect to find.

There was a short pause; then Tobbar spoke up. "Captain, I think maybe it's time to bring the passengers in on this. We can't hide the fact that we're in Taimyr system, so they're bound to figure out sooner or later that something's wrong. And I think they'll be more cooperative if we volunteer the information rather than making them demand it."

"What do we need their cooperation for?" Sarojis snorted.

"If you bothered to listen as much as you talked," Tobbar returned, a bit tartly, "you'd know that Chuck Raines is an advanced student in astrophysics and Dr. Chileogu has done a fair amount of work on Colloton field mathematics. I'd say chances are good that we're going to need help from one or both of them before this is all over."

I looked at Alana, raised my eyebrows questioningly. She hesitated, then nodded. "All right," I said. "Matope, you'll stay on duty down there; Alana will be in command here. Everyone else will assemble in the dining room. The meeting will begin in ten minutes."

I waited for their acknowledgments and then flipped off the intercom. "I'd like to be there," Alana said.

"I know," I said, raising my palms helplessly. "But I have to be there, and someone's got to keep an eye on things outside."

"Pascal or Sarojis could do it."

"True—and under normal circumstances I'd let them. But we're facing an unknown and potentially dangerous situation, and I need someone here whose judgment I trust."

She took a deep breath, exhaled loudly. "Yeah. Well... at least let me listen in by intercom, okay?"

"I'd planned to," I nodded. Reaching over, I touched her shoulder. "Don't worry; Bradley can handle the news."

"I know," she said, with a vehemence that told me she wasn't anywhere near that certain. Sighing, I flipped the PA switch and made the announcement.

—

They took the news considerably better than I'd expected them to—possibly, I suspected, because the emotional kick hadn't hit them yet.

"But this is absolutely unbelievable, Captain Durriken," Lissa Steadman said when I'd finished. She was a rising young business-administration type who I half- expected to call for a committee to study the problem. "How could a whole colony simply vanish?"

"My question exactly," I told her. "We don't know yet, but we're going to try and find out before we head back to Earth."

"We're just going to leave?" Mr. Eklund asked timidly from the far end of the table. His hand, on top of the table, gripped his wife's tightly, and I belatedly remembered they'd been going to Taimyr to see a daughter who'd emigrated some thirty years earlier. Of all aboard, they had lost the most when the colony vanished.

"I'm sorry," I told him, "but there's no way we could land and take off again, not if we want to make Earth again on the fuel we have left."

Eklund nodded silently. Beside them, Chuck Raines cleared his throat. "Has anybody considered the possibility that we're the ones something has happened to? After all, it's the Aura Dancer, not Taimyr, that's been dipping in and out of normal space for the last six weeks. Maybe during all that activity something went wrong."

"The floor is open for suggestions," I said.

"Well... I presume you've confirmed we are in the Taimyr system. Could we be—oh—out of phase or something with the real universe?"

"Highly poetic," Tobbar spoke up from his corner. "But what does out of phase physically mean in this case?"

"Something like a parallel universe, or maybe an alternate time line," Raines suggested. "Some replica of our universe where humans never colonized Taimyr. After all, cascade images are supposed to be views of alternate universes, aren't they? Maybe cascade points are somehow where all the possible paths intersect."

"You've been reading too much science fiction," I told him. "Cascade images are at least partly psychological, and they certainly have no visible substance. Besides, if you had to trace the proper path through a hundred universes every time you went through a cascade point, you'd lose ninety-nine ships out of every hundred that tried it."

"Actually, Mr. Raines is not being all that far out," Dr. Chileogu put in quietly. "It's occasionally been speculated that the branch cuts and Riemann surfaces that show up in Colloton theory represent distinct universes. If so, it would be theoretically possible to cross between them." He smiled slightly. "But it's extremely unlikely that a responsible captain would put his ship through the sort of maneuver that would be necessary to do such a thing."

"What sort of maneuver would it take?" I asked.

"Basically, a large-angle rotation within the cascade point. Say, eight degrees or more."

I shook my head, feeling relieved and at the same time vaguely disappointed that a possible lead had evaporated. "Our largest angle was just under four point five degrees."

He shrugged. "As I said."

I glanced around the table, wondering what avenue to try next. But Wilkinson wasn't ready to abandon this one yet. "I don't understand what the ship's rotation has to do with it, Dr. Chileogu," he said. "I thought the farther you rotated, the farther you went in real space, and that was all."

"Well... it would be easier if I could show you the curves involved. Basically, you're right about the distance-angle relation as long as you stay below that eight degrees I mentioned. But above that point there's a discontinuity, similar to what you get in the curve of the ordinary tangent function at ninety degrees; though unlike the tangent the next arm doesn't start at minus infinity." Chileogu glanced around the room, and I could see him revising the level of his explanation downward. "Anyway, the point is that the first arm of the curve—real rotations of zero to eight point six degrees—gives the complete range of translation distance from zero to infinity, and so that's all a star ship ever uses. If the ship rotates past that discontinuity, mathematical theory would say it had gone off the edge of the universe and started over again on a different Riemann surface. What that means physically I don't think anyone knows; but as Captain Durriken pointed out, all our real rotations have been well below the discontinuity."

Wilkinson nodded, apparently satisfied; but the term "real rotation" had now set off a warning bell deep in my own mind. It was an expression I hadn't heard— much less thought about—in years, but I vaguely remembered now that it had concealed a seven-liter can of worms. "Doctor, when you speak of a 'real' rotation, you're referring to a mathematical entity, as opposed to an actual, physical one," I said slowly. "Correct?"

He shrugged. "Correct, but with a ship such as this one the two are for all practical purposes identical. The Aura Dancer is a long, perfectly symmetrical craft, with both the Colloton-field generator and Ming-metal cargo shield along the center line. It's only when you start working with the fancier liners, with their towers and blister lounges and all, that you get a serious divergence."

I nodded carefully and looked around the room. Pascal had already gotten it, from the expression on his face; Wilkinson and Tobbar were starting to. "Could an extra piece of Ming metal, placed several meters off the ship's center line, cause such a divergence?" I asked Chileogu.

"Possibly." He frowned. "Very possibly."

I shifted my gaze to Lanton. His face had gone white. "I think," I said, "I've located the problem."

—

Seated at the main terminal in Pascal's cramped computer room, Chileogu turned the Ming-metal coil over in his hands and shook his head. "I'm sorry, Captain, but it simply can't be done. A dual crossover winding is one of the most complex shapes in existence, and there's no way I can calculate its effect with a computer this small."

I glanced over his head at Pascal and Lanton, the latter having tagged along after I cut short the meeting and hustled the mathematician down here. "Can't you even get us an estimate?" I asked.

"Certainly. But the estimate could be anywhere up to a factor of three off, which would be worse than useless to you."

I nodded, pursing my lips tightly. "Well, then, how about going on from here? With that coil back in the shield, the real and physical rotations coincide again. Is there some way we can get back to our universe; say, by taking a long step out from Taimyr and two short ones back?"

Chileogu pondered that one for a long minute. "I would say that it depends on how many universes we're actually dealing with," he said at last. "If there are just two—ours and this one—then rotating past any one discontinuity should do it. But if there are more than two, you'd wind up just going one deeper into the stack if you crossed the wrong line."

"Ouch," Pascal murmured. "And if there are an infinite number, I presume, we'd never get back out?"

The mathematician shrugged uncomfortably. "Very likely."

"But don't the mathematics show how many universes there are?" Lanton spoke up.

"They show how many Riemann surfaces there are," Chileogu corrected. "But physical reality is never obliged to correspond with our theories and constructs. Experimental checks are always required, and to the best of my knowledge no one has ever tried this one."

I thought of all the ships that had simply disappeared, and shivered slightly. "In other words, trying to find the Taimyr colony is out. All right, then. What about the principle of reversibility? Will that let us go back the way we came?" "Back to Earth?" Chileogu hesitated. "Ye-e-s, I think that would apply here. But to go back don't you need to know...?"

"The real rotations we used to get here," I nodded heavily. "Yeah." We looked at each other, and I saw that he, too, recognized the implications of that requirement.

Lanton, though, was still light-years behind us. "You act like there's still a problem," he said, looking back and forth between us. "Don't you have records of the rotations we made at each point?"

I was suddenly tired of the psychiatrist. "Pascal, would you explain things to Dr. Lanton—on your way back to the passenger area?"

"Sure." Pascal stepped to Lanton's side and took his arm. "This way, Doctor."

"But—" Lanton's protests were cut off by the closing door.

I sat down carefully on a corner of the console, staring back at the Korusyn 630 that took up most of the room's space. "I take it," Chileogu said quietly, "that you can't get the return-trip parameters?"

"We can get all but the last two points we'd need," I told him. "The ship's basic configuration was normal for all of those, and the Korusyn there can handle them." I shook my head. "But even for those the parameters will be totally different—a two-degree rotation one way might become a one or three on the return trip. It depends on our relation to the galactic magnetic field and angular momentum vectors, closest-approach distance to large masses, and a half-dozen other parameters. Even if we had a mathematical expression for the influence Lanton's damn coil had on our first two points, I wouldn't know how to reprogram the machine to take that into account."

Chileogu was silent for a moment. Then, straightening up in his seat, he flexed his fingers. "Well, I suppose we have to start somewhere. Can you clear me a section of memory?"

"Easily. What are you going to do?"

He picked up the coil again. "I can't do a complete calculation, but there are several approximation methods that occasionally work pretty well; they're scattered throughout my technical tapes if your library doesn't have a list. If they give widely varying results—as they probably will, I'm afraid—then we're back where we started. But if they happen to show a close agreement, we can probably use the result with reasonable confidence." He smiled slightly. "Then we get to worry about programming it in."

"Yeah. Well, first things first. Alana, have you been listening in?"

"Yes," her voice came promptly through the intercom. "I'm clearing the computer now."

Chileogu left a moment later to fetch his tapes. Pascal returned while he was gone, and I filled him in on what we were going to try. Together, he and Alana had the computer ready by the time Chileogu returned. I considered staying to watch, but common sense told me I would just be in the way, so instead I went up to the bridge and relieved Alana. It wasn't really my shift, but I didn't feel like mixing with the passengers, and I could think and brood as well on the bridge as I could in my cabin. Besides, I had a feeling Alana would like to check up on Bradley.

I'd been sitting there staring at Taimyr for about an hour when the intercom bleeped. "Captain," Alana's voice said, "can you come down to the dining room right away? Dr. Lanton's come up with an idea I think you'll want to hear."

I resisted my reflexive urge to tell her what Lanton could do with his ideas; her use of my title meant she wasn't alone. "All right," I sighed. "I'll get Sarojis to take over here and be down in a few minutes."

"I think Dr. Chileogu and Pascal should be here, too."

Something frosty went skittering down my back. Alana knew the importance of what those two were doing. Whatever Lanton's brainstorm was, she must genuinely think it worth listening to. "All right. We'll be there shortly."

They were all waiting quietly around one of the tables when I arrived. Bradley, not surprisingly, was there too, seated next to Alana and across from Lanton. Only the six of us were present; the other passengers, I guessed, were keeping the autobar in the lounge busy. "Okay, let's have it," I said without preamble as I sat down.

"Yes, sir," Lanton said, throwing a quick glance in Pascal's direction. "If I understood Mr. Pascal's earlier explanation correctly, we're basically stuck because there's no way to calibrate the Aura Dancer's instruments to take the, uh, extra Ming metal into account."

"Close enough," I grunted. "So?"

"So, it occurred to me that this 'real' rotation you were talking about ought to have some external manifestations, the same way a gyro needle shows the ship's physical rotation."

"You mean like something outside the viewports?" I frowned.

"No; something inside. I'm referring to the cascade images."

I opened my mouth, closed it again. My first thought was that it was the world's dumbest idea, but my second was why not? "You're saying, what, that the image-shuffling that occurs while we rotate is tied to the real rotation, each shift being a hundredth of a radian or something?" "Right"—he nodded—"although I don't know whether that kind of calibration would be possible."

I looked at Chileogu. "Doctor?"

The mathematician brought his gaze back from infinity. "I'm not sure what to say. The basic idea is actually not new—Colloton himself showed such a manifestation ought to be present, and several others have suggested the cascade images were it. But I've never heard of any actual test being made of the hypothesis; and from what I've heard of the images, I suspect there are grave practical problems besides. The pattern doesn't change in any mathematically predictable way, so I don't know how you would keep track of the shifts."

"I wouldn't have to," Lanton said. "I've been observing Rik's cascade images throughout the trip. I remember what the pattern looked like at both the beginning and ending of each rotation."

I looked at Bradley, suddenly understanding. His eyes met mine and he nodded fractionally.

"The only problem," Lanton continued, "is that I'm not sure we could set up at either end to do the reverse rotation."

"Chances are good we can," I said absently, my eyes still on Bradley. His expression was strangely hard for someone who was supposedly seeing the way out of permanent exile. Alana, if possible, looked even less happy. "All rotations are supposed to begin at zero, and since we always go 'forward' we always rotate the same direction."

I glanced back at Lanton to see his eyes go flat, as if he were watching a private movie. "You're right; it is the same starting pattern each time. I hadn't really noticed that before, with the changes and all."

"It should be easy enough to check, Captain," Pascal spoke up. "We can compute the physical rotations for the first six points we'll be going through. The real rotations should be the same as on the outbound leg, though, so if Dr. Lanton's right the images will wind up in the same pattern they did before."

"But how—?" Chileogu broke off suddenly. "Ah. You've had a mnemonic treatment?"

Lanton nodded and then looked at me. "I think Mr. Pascal's idea is a good one, Captain, and I don't see any purpose in hanging around here any longer than necessary. Whenever you want to start back—"

"I have a few questions to ask first," I interrupted mildly. I glanced at Bradley, decided to tackle the easier ones first. "Dr. Chileogu, what's the status of your project?"

"The approximations? We've just finished programming the first one; it'll take another hour or so to collect enough data for a plot. I agree with Dr. Lanton, though—we can do the calculations between cascade points as easily as we can do them in orbit here."

"Thank you. Dr. Lanton, you mentioned something about changes a minute ago. What exactly did you mean?"

Lanton's eyes flicked to Bradley for an instant. "Well... as I told you several weeks ago, a person's mind has a certain effect on the cascade image pattern. Some of the medicines Rik's been taking have slightly altered the—oh, I guess you could call it the texture of the pattern."

"Altered it how much?"

"In some cases, fairly extensively." He hesitated, just a bit too long. "But nothing I've done is absolutely irreversible. I should be able to re-create the original conditions before each cascade point."

Deliberately, I leaned back in my chair. "All right. Now let's hear what the problem is."

"I beg your pardon?"

"You heard me." I waved at Bradley and Alana. "Your patient and my first officer look like they're about to leave for a funeral. I want to know why."

Lanton's cheek twitched. "I don't think this is the time Or the place to discuss—"

"The problem, Captain," Bradley interrupted quietly, "is that the reversing of the treatments may turn out to be permanent."

It took a moment for that to sink in. When it did I turned my eyes back on Lanton. "Explain."

The psychiatrist took a deep breath. "The day after the second point I used ultrasound to perform a type of minor neurosurgery called synapse fixing. It applies heat to selected regions of the brain to correct a tendency of the nerves to misfire. The effects can be reversed... but the procedures been done only rarely, and usually involves unavoidable peripheral damage."

I felt my gaze hardening into an icy stare. "In other words," I bit out, "not only will the progress he's made lately be reversed, but he'll likely wind up worse off than he started. Is that it?"

Lanton squirmed uncomfortably, avoiding my eyes. "I don't know that he will. Now that I've found a treatment—"

"You're about to give him a brand-new disorder," I snapped. "Damn it all, Lanton, you are the most coldblooded—" "Captain."

Bradley's single word cut off my flow of invective faster than anything but hard vacuum could have. "What?" I said.

"Captain, I understand how you feel." His voice was quiet but firm; and though the tightness remained in his expression, it had been joined by an odd sort of determination. "But Dr. Lanton wasn't really trying to maneuver you into supporting something unethical. For the record, I've already agreed to work with him on this; I'll put that on tape if you'd like." He smiled slightly. "And before you bring it up, I am recognized as legally responsible for my actions, so as long as Dr. Lanton and I agree on a course of treatment your agreement is not required."

"That's not entirely true," I ground out. "As a ship's captain in deep space, I have full legal power here. If I say he can't do something to you, he can't. Period."

Bradley's face never changed. "Perhaps. But unless you can find another way to get us back to Earth, I don't see that you have any other choice."

I stared into those eyes for a couple of heartbeats. Then, slowly, my gaze swept the table, touching in turn all the others as they sat watching me, awaiting my decision. The thought of deliberately sending Bradley back to his permanent disorientation—really permanent, this time—left a taste in my mouth that was practically gagging in its intensity. But Bradley was right... and at the moment I didn't have any better ideas.

"Pascal," I said, "you and Dr. Chileogu will first of all get some output on that program of yours. Alana, as soon as they're finished you'll take the computer back and calculate the parameters for our first point. You two"—I glared in turn at Bradley and Lanton—"will be ready to test this image theory of yours. You'll do the observations in your cabin as usual, and tell me afterwards whether we duplicated the rotation exactly or came out short or long. Questions? All right; dismissed."

After all, I thought amid the general scraping of chairs, for the first six points all Bradley will need to do is cut back on medicines. That means twenty-eight days or so before any irreversible surgery is done.

I had just that long to come up with another answer.

—

We left orbit three hours later, pushing outward on low drive to conserve fuel. That plus the course I'd chosen meant another ten hours until we were in position for the first point, but none of that time was wasted. Pascal and Chileogu were able to program and run two more approximation schemes; the results, unfortunately, were not encouraging. Any two of the three plots had a fair chance of agreeing over ranges of half a degree or so, but there was no consistency at all over the larger angles we would need to use. Chileogu refused to throw in the towel, pointing out that he had another six methods to try and making vague noises about statistical curve-fitting schemes. I promised him all the computer time he needed between point maneuvers, but privately I conceded defeat. Lanton's method now seemed our only chance... if it worked.

I handled the first point myself, double-checking all parameters beforehand and taking special pains to run the gyro needle as close to the proper angle as I could. As with any such hand operation, of course, perfection was not quite possible, and I ran the Dancer something under a hundredth of a degree long. I'm not sure what I was expecting from this first test, but I was more than a little surprised when Lanton accurately reported that we'd slightly overshot the mark.

"It looks like it'll work," Alana commented from her cabin when I relayed the news. She didn't sound too enthusiastic.

"Maybe," I said, feeling somehow the need to be as skeptical as possible. "We'll see what happens when he starts taking Bradley off the drugs. I find it hard to believe that the man's mental state can be played like a yo-yo, and if it can't be we'll have to go with whatever statistical magic Chileogu can put together."

Alana gave a little snort that she'd probably meant to be a laugh. "Hard to know which way to hope, isn't it?"

"Yeah." I hesitated for a second, running the duty arrangements over in my mind. "Look, why don't you take the next few days off, at least until the next point. Sarojis can take your shift up here."

"That's all right," she sighed. "I—if it's all the same with you, I'd rather save any offtime until later. Rik will... need my help more then."

"Okay," I told her. "Just let me know when you want it and the time's yours."

We continued on our slow way, and with each cascade point I became more and more convinced that Lanton really would be able to guide us through those last two critical points. His accuracy for the first four maneuvers was a solid hundred percent, and on the fifth maneuver we got to within point zero two percent of the computer's previous reading by deliberately jockeying the Dancer back and forth until Bradley's image pattern was exactly as Lanton remembered it. After that even Matope was willing to be cautiously optimistic; and if it hadn't been for one small cloud hanging over my head I probably would have been as happy as the rest of the passengers had become.

The cloud, of course, being Bradley.

I'd been wrong about how much his improvement had been due to the drugs Lanton had been giving him, and every time I saw him that ill-considered line about playing his mind like a yo-yo came back to haunt me. Slowly, but very steadily, Bradley was regressing toward his original mental state. His face went first, his expressions beginning to crowd each other again as if he were unable to decide which of several moods should be expressed at any given moment. His eyes took on that shining, nervous look I hated so much: just occasionally at first, but gradually becoming more and more frequent, until it seemed to be almost his norm. And yet, even though he certainly saw what was happening to him, not once did I hear him say anything that could be taken as resentment or complaint. It was as if the chance to save twenty other lives was so important to him that it was worth any sacrifice. I thought occasionally about Alana's comment that he'd never before had a sense of dignity, and wondered if he would lose it again to his illness. But I didn't wonder about it all that much; I was too busy worrying about Alana.

I hadn't expected her to take Bradley's regression well, of course—to someone with Alana's wing-mending instincts a backsliding patient would be both insult and injury. What I wasn't prepared for was her abrupt withdrawal into a shell of silence on the issue which no amount of gentle probing could crack open. I tried to be patient with her, figuring that eventually the need to talk would overcome her reticence; but as the day for what Lanton described as "minor surgery" approached, I finally decided I couldn't wait any longer. On the day after our sixth cascade point, I quit being subtle and forced the issue.

"Whatever I'm feeling, it isn't any concern of yours," she said, her fingers playing across the bridge controls as she prepared to take over from me. Her hands belied the calmness in her voice: I knew her usual checkout routine as well as my own, and she lost the sequence no fewer than three times while I watched.

"I think it is," I told her. "Aside from questions of friendship, you're a member of my crew, and anything that might interfere with your efficiency is my concern."

She snorted. "I've been under worse strains than this without falling apart."

"I know. But you've never buried yourself this deeply before, and it worries me."

"I know. I'm... sorry. If I could put it into words—" She shrugged helplessly.

"Are you worried about Bradley?" I prompted. "Don't forget that, whatever Lanton has to do here, he'll have all the resources of the Swedish Psychiatric Institute available to undo it."

"I know. But... he's going to come out of it a different person. Even Lanton has to admit that."

"Well... maybe it'll wind up being a change for the better."

It was a stupid remark, and her scornful look didn't make me feel any better about having made it. "Oh, come on. Have you ever heard of an injury that did any real good? Because that's what it's going to be—an injury."

And suddenly I understood. "You're afraid you won't like him afterwards, aren't you? At least not the way you do now?"

"Why should that be so unreasonable?" she snapped. "I'm a damn fussy person, you know—I don't like an awful lot of people. I can't afford to... to lose any of them." She turned her back on me abruptly, and I saw her shoulders shake once.

I waited a decent interval before speaking. "Look, Alana, you're not in any shape to stay up here alone. Why don't you go down to your cabin and pull yourself together, and then go and spend some time with Bradley."

"I'm all right," she mumbled. "I can take my shift."

"I know. But... at the moment I imagine Rik needs you more than I do. Go on, get below."

She resisted for a few more minutes, but eventually I bent her sense of duty far enough and she left. For a long time afterwards I just sat and stared at the stars, my thoughts whistling around my head in tight orbit. What would the effect of the new Bradley be on Alana? She'd been right—whatever happened, it wasn't likely to be an improvement. If her interest was really only in wing-mending, Lanton's work would provide her with a brand-new challenge. But I didn't think even Alana was able to fool herself like that anymore. She cared about him, for sure, and if he changed too much that feeling might well die.

And I wouldn't lose her when we landed.

I thought about it long and hard, examining it and the rest of our situation from several angles. Finally, I leaned forward and keyed the intercom. Wilkinson was off duty in his cabin; from the time it took him to answer he must have been asleep as well. "Wilkinson, you got a good look at the damage in Lanton's neural whatsis machine. How hard would it be to fix?"

"Uh... well, that's hard to say. The thing that spit goop all over the Ming-metal coil was a standard voltage regulator board—we're bound to have spares aboard. But there may be other damage, too. I'd have to run an analyzer over it to find out if anything else is dead. Whether we would have replacements is another question."

"Okay. Starting right now, you're relieved of all other duty until you've got that thing running again. Use anything you need from ship's spares—" I hesitated—"and you can even pirate from our cargo if necessary."

"Yes, sir." He was wide awake now. "I gather there's a deadline?"

"Lanton's going to be doing some ultrasound work on Bradley in fifty-eight hours. You need to be done before that. Oh, and you'll need to work in Lanton's cabin—I don't want the machine moved at all."

"Got it. If you'll clear it with Lanton, I can be up there in twenty minutes."

Lanton wasn't all that enthusiastic about letting Wilkinson set up shop in his cabin, especially when I wouldn't explain my reasons to him, but eventually he gave in. I alerted Kate Epstein that she would have to do without Wilkinson for a while, and then called Matope to confirm the projects access to took and spares.

And then, for the time being, it was all over but the waiting. I resumed my examination of the viewport, wondering if I were being smart or just pipe- dreaming.

Two days later—barely eight hours before Bradley's operation was due to begin—Wilkinson finally reported that the neural tracer was once again operational.

—

"This better be important," Lanton fumed as he took his place at the dining- room table. "I'm already behind schedule in my equipment setup as it is."

I glanced around at the others before replying. Pascal and Chileogu, fresh from their latest attempt at making sense from their assortment of plots, seemed tired and irritated by this interruption. Bradley and Alana, holding hands tightly under the table, looked more resigned than anything else. Everyone seemed a little gaunt, but that was probably my imagination—certainly we weren't on anything approaching starvation rations yet. "Actually, Doctor," I said, looking back at Lanton, "you're not in nearly the hurry you think. There's not going to be any operation."

That got everyone's full attention. "You've found another way?" Alana breathed, a hint of life touching her eyes for the first time in days.

"I think so. Dr. Chileogu, I need to know first whether a current running through Ming metal would change its effect on the ship's real rotation."

He frowned, then shrugged. "Probably. I have no idea how, though."

A good thing I'd had the gadget fixed, then. "Doesn't matter. Dr. Lanton, can you tell me approximately when in the cascade point your neural tracer burned out?"

"I can tell you exactly. It was just as the images started disappearing, right at the end."

I nodded; I'd hoped it was either the turning on or off of the field generator that had done it. That would make the logistics a whole lot easier. "Good. Then we're all set. What we're going to do, you see, is reenact that particular maneuver."

"What good will that do?" Lanton asked, his tone more puzzled than belligerent.

"It should get us home." I waved toward the outer hull. "For the past two days we've been moving toward a position where the galactic field and other parameters are almost exactly the same as we had when we went through that point— providing your neural tracer is on and we're heading back toward Taimyr. In another two days we'll turn around and get our velocity vector lined up correctly. Then, with your tracer running, we're going to fire up the generator and rotate the same amount—by gyro reading—as we did then. You"—I leveled a finger at Lanton—"will be on the bridge during that operation, and you will note the exact configuration of your cascade images at that moment. Then, without shutting off the generator, we'll rotate back to zero; zero as defined by your cascade pattern, since it may be different from gyro zero. At that time, I'll take the Ming metal from your tracer, walk it to the number one hold, and stuff it into the cargo shield; and we'll rotate the ship again until we reach your memorized cascade pattern. Since the physical and real rotations are identical in that configuration, that'll give us the real angle we rotated through the last time—"

"And from that we can figure the angle we'll need to make going the other direction!" Alana all but shouted.

I nodded. "Once we've rotated back to zero to regain our starting point, of course." I looked around at them again. Lanton and Bradley still seemed confused, though the latter was starting to catch Alana's enthusiasm. Chileogu was scribbling on a notepad, and Pascal just sat there with his mouth slightly open. Probably astonished that he hadn't come up with such a crazy idea himself. "That's all I have to say," I told them. "If you have any comments later—"

"I have one now, Captain."

I looked at Bradley in some surprise. "Yes?"

He swallowed visibly. "It seems to me, sir, that what you're going to need is a set of cascade images that vary a lot, so that the pattern you're looking for is a distinctive one. I don't think Dr. Lanton's are suitable for that."

"I see." Of course; while Lanton had been studying Bradley's images, Bradley couldn't help but see his, as well. "Lanton? How about it?"

The psychiatrist shrugged. "I admit they're a little bland—I haven't had a very exciting life. But they'll do."

"I doubt it." Bradley looked back at me. "Captain, I'd like to volunteer."

"You don't know what you're saying," I told him. "Each rotation will take twice as long as the ones you've already been through. And there'll be two of them back to back; and the field won't be shut down between them, because I want to know if the images drift while I'm moving the coil around the ship. Multiply by about five what you've felt afterwards and you'll get some idea what it'll be like." I shook my head. "I'm grateful for your offer, but I can't let more people than necessary go through that."

"I appreciate that. But I'm still going to do it."

We locked eyes for a long moment... and the word dignity flashed through my mind. "In that case, I accept," I said. "Other questions? Thank you for stopping by."

They got the message and began standing up... all except Alana. Bradley whispered something to her, but she shook her head and whispered back. Reluctantly, he let go of her hand and followed the others out of the room.

"Question?" I asked Alana when we were alone, bracing for an argument over the role I was letting Bradley take.

"You're right about the extra stress staying in Colloton space that long will create," she said. "That probably goes double for anyone running around in it. I'd expect a lot more vertigo, for starters, and that could make movement dangerous."

"Would you rather Bradley had his brain scorched?"

She flinched, but stood her ground. "My objection isn't with the method—it's with who's going to be bouncing off the Dancer's walls."

"Oh. Well, before you get the idea you're being left out of things, let me point out that you're going to be handling bridge duties for the maneuver."

"Fine; but since I'm going to be up anyway I want the job of running the Ming metal back and forth instead."

I shook my head. "No. You're right about the unknowns involved with this, which is why I'm going to do it."

"I'm five years younger than you are," she said, ticking off fingers. "I also have a higher stress index, better balance, and I'm in better physical condition." She hesitated. "And I'm not haunted by white uniforms in my cascade images," she added gently.

Coming from anyone else, that last would have been like a knife in the gut. But from Alana, it somehow didn't even sting. "The assignments are nonnegotiable," I said, getting to my feet. "Now if you'll excuse me, I have to catch a little sleep before my next shift."

She didn't respond. When I left she was still sitting there, staring through the shiny surface of the table.

—

"Here we go. Good Luck," were the last words I heard Alana say before the intercom was shut down and I was alone in Lanton's cabin. Alone, but not for long: a moment later my first doubles appeared. Raising my wrist, I keyed my chrono to stopwatch mode and waited, ears tingling with the faint ululation of the Colloton field generator. The sound, inaudible from the bridge, reminded me of my trainee days, before the Dancer... before Lord Hendrik and his fool-headed kid.... Shaking my head sharply, I focused on the images, waiting for them to begin their one- dimensional allemande. They did, and I started my timer. With the lines to the bridge dead I was going to have to rely on the image movements to let me know when the first part of the maneuver was over; moving the Ming metal around the ship while we were at the wrong end of our rotation or—worse—while we were still moving would probably end our chances of getting back for good. Mindful of the pranks cascade points could play on a person's time sense, I'd had Pascal calculate the approximate times each rotation would take. Depending on how accurate they turned out to be, they might simply let me limit how soon I started worrying.

It wasn't a pleasant wait. On the bridge, I had various duties to perform; here, I didn't have even that much distraction from the ghosts surrounding me. Sitting next to the humming neural tracer, I watched the images flicker in and out, white uniforms dos-a-dosing with the coveralls and the gaps.

Ghosts. Haunted. I'd never seriously thought of them like that before, but now I found I couldn't see them in any other way. I imagined I could see knowing smiles on the liner captains' faces, or feel a coldness from the gaps where I'd died. Pure autosuggestion, of course... and yet, it forced me for probably the first time to consider what exactly the images were doing to me.

They were making me chronically discontented with my life.

My first reaction to such an idea was to immediately justify my resentment I'd been cheated out of the chance to be a success in my field; trapped at the bottom of the heap by idiots who ranked political weaselcraft higher than flying skill. I had a right to feel dumped on.

And yet...

My watch clicked at me: the first rotation should be about over. I reset it and waited, watching the images. With agonizing slowness they came to a stop... and then started moving again in what I could persuade myself was the opposite direction. I started my watch again and let my eyes defocus a bit. The next time the dance stopped, it would be time to move Lanton's damn coil to the hold and bring my ship back to normal.

My ship. I listened to the way the words echoed around my brain. My ship. No liner captain owned his own ship. He was an employee, like any other in the company; forever under the basilisk eye of those selfsame idiots who'd fired me once for doing my job. The space junk being sparser and all that aside, would I really have been happier in a job like that? Would I have enjoyed being caught between management on one hand and upper-crusty passengers on the other? Enjoyed, hell—would I have survived it? For the first time in ten years I began to wonder if perhaps Lord Hendrik had known what he was doing when he booted me out of his company.

Deliberately, I searched out the white uniforms far off to my left and watched as they popped in and out of different slots in the long line. Perhaps that was why there were so few of them, I thought suddenly; perhaps, even while I was pretending otherwise, I'd been smart enough to make decisions that had kept me out of the running for that particular treadmill. The picture that created made me smile: my subconscious chasing around with secret memos, hiding basic policy matters from my righteously indignant conscious mind.

The click of my watch made me jump. Taking a deep breath, I picked up a screwdriver from the tool pouch laid out beside the neural tracer and gave my full attention to the images. Slow... slower... stopped. I waited a full two minutes to make sure, then flipped off the tracer and got to work.

I'd had plenty of practice in the past two days, but it still took me nearly five minutes to extricate the coil from the maze of equipment surrounding it. That was no particular problem—we'd allowed seven minutes for the disassembly—but I was still starting to sweat as I got to my feet and headed for the door.

And promptly fell on my face.

Alana's reference to enhanced vertigo apart, I hadn't expected anything that strong quite so soon. Swallowing hard, I tried to ignore the feeling of lying on a steep hill and crawled toward the nearest wall. Using it as a support, I got to my feet, waited for the cabin to stop spinning, and shuffled over to the door. Fortunately, all the doors between me and One Hold had been locked open, so I didn't have to worry about getting to the release. Still shuffling, I maneuvered through the opening and started down the corridor, moving as quickly as I could. The trip—fifteen meters of corridor, a circular stairway down, five more meters of corridor, and squeezing through One Hold's cargo to get to the shields—normally took less than three minutes. We'd allowed ten; but already I could see that was going to be tight. I kept my eyes on the wall beside me and concentrated on moving my feet... which was probably why I was nearly to the stairway before I noticed the kaleidoscope dance my cascade images were doing.

While the ship was at rest.

I stopped short, the pattern shifts ceasing as I did so. The thing I had feared most about this whole trick was happening: moving the Ming metal was changing our real angle in Colloton space.

I don't know how long I leaned there with the sweat trickling down my forehead, but it was probably no more than a minute before I forced myself to get moving again. There were now exactly two responses Alana could make: go on to the endpoint Lanton had just memorized, or try and compensate somehow for the shift I was causing. The former course felt intuitively wrong, but the latter might well be impossible to do—and neither had any particular mathematical backing that Chileogu had been able to find. For me, the worst part of it was the fact that I was now completely out of the decision process. No matter how fast I got the coil locked away, there was no way I was going to make it back up two flights of stairs to the bridge. Like everyone else on board, I was just going to have to trust Alana's judgment.

I slammed into the edge of the stairway opening, nearly starting my downward trip headfirst before I got a grip on the railing. The coil, jarred from my sweaty hand, went on ahead of me, clanging like a muffled bell as it bounced to the deck below. I followed a good deal more slowly, the writhing images around me adding to my vertigo. By now, the rest of my body was also starting to react to the stress, and I had to stop every few steps as a wave of nausea or fatigue washed over me. It seemed forever before I finally reached the bottom of the stairs. The coil had rolled to the middle of the corridor; retrieving it on hands and knees, I got back to the wall and hauled myself to my feet. I didn't dare look at my watch.

The cargo hold was the worst part yet. The floor was swaying freely by then, like an ocean vessel in heavy seas, and through the reddish haze surrounding me, the stacks of boxes I staggered between seemed ready to hurl themselves down upon my head. I don't remember how many times I shied back from what appeared to be a breaking wave of crates, only to slam into the stack behind me. Finally, though, I made it to the open area in front of the shield door. I was halfway across the gap, moving again on hands and knees, when my watch sounded the one- minute warning. With a desperate lunge, I pushed myself up and forward, running full tilt into the Ming-metal wall. More from good luck than anything else, my free hand caught the handle; and as I fell backwards the door swung open. For a moment I hung there, trying to get my trembling muscles to respond. Then, slowly, I got my feet under me and stood up. Reaching through the opening, I let go of the coil and watched it drop into the gap between two boxes. The hold was swaying more and more violently now; timing my move carefully, I shoved on the handle and collapsed to the deck. The door slammed shut with a thunderclap that tried to take the top of my head with it. I hung on just long enough to see that the door was indeed closed, and then gave in to the darkness.

I'm told they found me sleeping with my back against the shield door, making sure it couldn't accidentally come open.

—

I was lying on my back when I came to, and the first thing I saw when I opened my eyes was Kate Epsteins face. "How do you feel?" she asked.

"Fine," I told her, frowning as I glanced around. This wasn't my cabin.... With a start I recognized the humming in my ear. "What the hell am I doing in Lanton's cabin?" I growled.

Kate shrugged and reached over my shoulder, shutting off the neural tracer. "We needed Dr. Lanton's neural equipment, and the tracer wasn't supposed to be moved. A variant of the mountain/Mohammed problem, I guess you could say."

I grunted. "How'd the point maneuver go? Was Alana able to figure out a correction factor?"

"It went perfectly well," Alana's voice came from my right. I turned my head, to find her sitting next to the door. "I think we're out of the woods now, Pall—that four-point-four physical rotation turned out to be more like nine point one once the coil was out of the way. If Chileogu's right about reversibility applying here, we should be back in our own universe now. I guess we won't know for sure until we go through the next point and reach Earth." "Is that nine point one with or without a correction factor?" I asked, my stomach tightening in anticipation. We might not be out of the woods quite yet.

"No correction needed," she said. "The images on the bridge stayed rock- steady the whole time."

"But... I saw them shifting."

"Yes, you told us that. Our best guess—excuse me; Pascal's best guess—is that you were getting that because you were moving relative to the field generator, that if you'd made a complete loop around it you would've come back to the original cascade pattern again. Chileogu's trying to prove that mathematically, but I doubt he'll be able to until he gets to better facilities."

"Uh-huh." Something wasn't quite right here. "You say I told you about the images? When?"

Alana hesitated, looked at Kate. "Actually, Captain," the doctor said gently, "you've been conscious quite a bit during the past four days. The reason you don't remember any of it is that the connection between your short-term and long-term memories got a little scrambled—probably another effect of your jaunt across all those field lines. It looks like that part's healed itself, though, so you shouldn't have any more memory problems."

"Oh, great. What sort of problems will I have more of?"

"Nothing major. You might have balance difficulties for a while, and you'll likely have a mild migraine or two within the next couple of weeks. But indications are that all of it is very temporary."

I looked back at Alana. "Four days. We'll need to set up our last calibration run soon."

"All taken care of," she assured me. "We're turning around later today to get our velocity vector pointing back toward Taimyr again, and we'll be able to do the run tomorrow."

"Who's going to handle it?"

"Who do you think?" she snorted. "Rik, Lanton, and me, with maybe some help from Pascal."

I'd known that answer was coming, but it still made my mouth go dry. "No way," I told her, struggling to sit up. "You aren't going to go through this hell. I can manage—"

"Ease up, Pall," Alana interrupted me. "Weren't you paying attention? The real angle doesn't drift when the Ming metal is moved, and that means we can shut down the field generator while I'm taking the coil from here to One Hold again." I sank back onto the bed, feeling foolish. "Oh. Right."

Getting to her feet, Alana came over to me and patted my shoulder. "Don't worry," she said in a kinder tone. "We've got things under control. You've done the hard part; just relax and let us do the rest."

"Okay," I agreed, trying to hide my misgivings.

It was just as well that I did. Thirty-eight hours later Alana used our last gram of fuel in a flawless bit of flying that put us into a deep Earth orbit. The patrol boats that had responded to her emergency signal were waiting there, loaded with the fuel we would need to land.

Six hours after that, we were home.

—

They checked me into a hospital, just to be on the safe side, and the next four days were filled with a flurry of tests, medical interviews, and bumpy wheelchair rides. Surprisingly—to me, anyway—I was also nailed by two media types who wanted the more traditional type of interview. Apparently, the Dancer's trip to elsewhere and back was getting a fair amount of publicity. Just how widespread the coverage was, though, I didn't realize until my last day there, when an official- looking CompNote was delivered to my room.

It was from Lord Hendrik.

I snapped the sealer and unfolded the paper. The first couple of paragraphs— the greetings, congratulations on my safe return, and such—I skipped over quickly, my eyes zeroing in on the business portion of the letter:

As you may or may not know, I have recently come out of semiretirement to serve on the Board of Directors of TranStar Enterprises, headquartered here in Nairobi. With excellent contacts both in Africa and in the so-called Black Colony chain, our passenger load is expanding rapidly, and we are constantly on the search for experienced and resourceful pilots we can entrust them to. The news reports of your recent close call brought you to my mind again after all these years, and I thought you might be interested in discussing—

A knock on the door interrupted my reading. "Come in," I called, looking up.

It was Alana. "Hi, Pall, how are you doing?" she asked, walking over to the bed and giving me a brief once-over. In one hand she carried a slender plastic portfolio.

"Bored silly," I told her. "I think I'm about ready to check out—they've finished all the standard tests without finding anything, and I'm tired of lying around while they dream up new ones."

"What a shame," she said with mock sorrow. "And after I brought you all this reading material, too." She hefted the portfolio.

"What is it, your resignation?" I asked, trying to keep my voice light. There was no point making this any more painful for either of us than necessary.

But she just frowned. "Don't be silly. It's a whole batch of new contracts I've picked up for us in the past few days. Some really good ones, too, from name corporations. I think people are starting to see what a really good carrier we are."

I snorted. "Aside from the thirty-six or whatever penalty clauses we invoked on this trip?"

"Oh, that's all in here too. The Swedish Institute's not even going to put up a fight—they're paying off everything, including your hospital bills and the patrol's rescue fee. Probably figured Lanton's glitch was going to make them look bad enough without them trying to chisel us out of damages too." She hesitated, and an odd expression flickered across her face. "Were you really expecting me to jump ship?"

"I was about eighty percent sure," I said, fudging my estimate down about nineteen points. "After all, this is where Rik Bradley's going to be, and you... rather like him. Don't you?"

She shrugged. "I don't know what I feel for him, to be perfectly honest. I like him, sure—like him a lot. But my life's out there"—she gestured skyward—"and I don't think I can give that up for anyone. At least, not for him."

"You could take a leave of absence," I told her, feeling like a prize fool but determined to give her every possible option. "Maybe once you spend some real time on a planet, you'd find you like it."

"And maybe I wouldn't," she countered. "And when I decided I'd had enough, where would the Dancer be? Probably nowhere I'd ever be able to get to you." She looked me straight in the eye and all traces of levity vanished from her voice. "Like I told you once before, Pall, I can't afford to lose any of my friends."

I took a deep breath and carefully let it out. "Well. I guess that's all settled. Good. Now, if you'll be kind enough to tell the nurse out by the monitor station that I'm signing out, I'll get dressed and we'll get back to the ship."

"Great. It'll be good to have you back." Smiling, she disappeared out into the corridor.

Carefully, I got my clothes out of the closet and began putting them on, an odd mixture of victory and defeat settling into my stomach. Alana was staying with the Dancer, which was certainly what I'd wanted... and yet, I couldn't help but feel that in some ways her decision was more a default than a real, active choice. Was she coming back because she wanted to, or merely because we were a safer course than the set of unknowns that Bradley offered? If the latter, it was clear that her old burns weren't entirely healed; that she still had a ways—maybe a long ways—to go. But that was all right. I may not have the talent she did for healing bruised souls, but if time and distance were what she needed, the Dancer and I could supply her with both.

I was just sealing my boots when Alana returned. "Finished? Good. They're getting your release ready, so let's go. Don't forget your letter," she added, pointing at Lord Hendrik's CompNote.

"This? It's nothing," I told her, crumpling it up and tossing it toward the wastebasket. "Just some junk mail from an old admirer."

—

Six months later, on our third point out from Prima, a new image of myself in liner captain's white appeared in my cascade pattern. I looked at it long and hard... and then did something I'd never done before for such an image.

I wished it lots of luck.

Afterword

"Cascade Point" started out as a raw idea—the visual effects of the Colloton Drive—plus a simple statement of the story problem— the ship getting lost through some sort of malfunction. That was it; and for me that's not a heck of a lot to start with. It was one of the few stories I've done where I was willing to just jump in without any real idea of where it was going or even where it was ultimately going to end up. Somewhere along the line the details worked themselves out, and the characters fleshed themselves out, and the story found its proper conclusion... and apparently it was the right conclusion, because the fans at the 1984 World Science Fiction Convention in Los Angeles voted it a Hugo Award for best novella of the year. There is no greater reward for a writer than to know the readers enjoy his work; that reward, not the Hugo itself, is the memory this story will always hold for me.

And with that final bit of philosophy we find ourselves at the end of the book. From "The Dreamsender" to "Return to the Fold" you've seen five years of style development as I've slowly grown from semi-rank amateur to at least journeyman status in this field, and from wading through all these afterwords you've perhaps gotten some insight into the view I have of those same five years. I hope you've found both journeys worthwhile.
