The Last Theorem

38 THE HUNT FOR NATASHA SUBRAMANIAN

What the three fourths of the Subramanian family that remained on Earth had resolved to do was carry on with as normal a life as was possible, with the other quarter of the family gallivanting through cislunar space in a contraption of plastic and buckyball carbon. Accordingly, once they had sent Natasha their final good luck message, Ranjit had got on his bike to head for his office. Myra had seen the possibility of a whole hour, maybe two, for her to try to catch up on what her increasing backlog of journals had to say about some of the hotter subjects in the area of AI and prostheses. Such gifts of a few personal hours were not frequent. They came when young Robert was asleep, or when he was at his special school, or when he was, as now, dutifully following the housemaid around, helping her—or, more accurately, “helping” her—with her early-morning tasks of making beds and tidying rooms.

So, with a cooling cup of tea on the table before her—and, of course, with the news programs playing on her room screen in case, however improbably, something unexpected occurred in Natasha’s race—Myra was trying to make sense of some of her journals when she heard the sound of her son’s heartbroken sobbing.

She looked up and saw the maid carrying him into the room. “I don’t know what happened, missus,” the maid said, sounding struck. “We were emptying out the wastebaskets when Robert suddenly sat down and began to cry. Robert never cries, missus!”

Which Myra, of course, knew as well as she did. But there it was. So Myra did what untold billions of other mothers have done, all the way from the australopithecines. She took her son in her arms and rocked him soothingly, murmuring into his ear. It didn’t stop the crying, no, but the tears simmered down to sobs. Myra was asking herself whether this unusual and troubling—but certainly not life-threatening—development warranted calling her husband at his office, when there was a stifled shriek from the maid. Myra looked up.

There on the screen was the image of her daughter’s solar yacht. Apart from the fact that one edge was, ever so slightly, tipped up, it looked exactly as it had an hour earlier. But now there was a red banner underneath the image that said “Accident in lunar race?” And when the audio volume was turned up, there was no question mark in the agitated remarks of the newscaster. Something bad had happened to Diana. Worst of all, Diana’s pilot—which was to say, Myra’s beloved daughter—was not answering distress calls from the commodore, and it seemed that whatever had gone wrong with the solar yacht had somehow abducted its pilot.

Myra Subramanian’s terrible worry was perhaps the most personal distress anyone in the world can feel, but she was not alone. The more the tender vessels dug into the puzzle of what had happened to Diana, the more hopelessly unanswerable the puzzle seemed.

Emergency workers from the commodore’s yacht had long since suited up and reached Diana’s command capsule. They managed to gain entrance, searched it, found no trace of its pilot. But that was not the worst. More detailed examination showed that the register on the capsule’s one air lock showed unequivocally that it had not been opened since Natasha herself had entered, to begin the race. So Natasha was not only missing; she had never even left her command capsule.

All of which, of course, was quite impossible. And also unarguably true.

Also of course, the commodore and his staff had several dozen other problems to try to solve, all at once. There were the six other solar yachts, no longer in an orderly line, now in some danger of colliding with one another as their pilots were distracted by what had happened to the seventh of their group. The order went out to each of them to furl their sails and await pickup. That would leave the craft as six little bullets of matter that would have to be followed and somehow steered into parking orbits that would not threaten other space traffic…but not right away. Those problems could be dealt with in an orderly fashion, when time permitted.

There was nothing orderly, however, in what had become of Natasha Subramanian. Her disappearance, in the circumstances in which it had occurred, was simply impossible. And all of that was very bad for everyone concerned, and then it got worse.

For the next thirty-six hours the whole remaining Subramanian family was gathered in their kitchen, maid and cook as well. When Robert woke up from his nap, the crying spell was over, though he didn’t seem able to tell his parents what it had been about—until they asked him if it had something to do with his sister and he replied, “’Atasha ’appy asleep.”

When dinner arrived, he ate with a good appetite, although no one else did. They didn’t sleep much, either, drowsing in their chairs or stretching out for half an hour or so on the couch under the kitchen’s windows. But none of the adults dared walk away from the news screens for more than a couple of minutes, lest some explanation of what had happened might suddenly be announced.

None was.

Oh, there was news, all right. One worrying bulletin came from the searchers in low earth orbit to say that now they were being escorted by several dozen of those little copper-colored flying things that had given the world its first solid indication that flying saucers, or something like flying saucers, were real. Why were they there? What did they want? Speculation was intense, but no explanation emerged, and so the world’s attention turned to other matters. Attention turned to that spot in the Oort where astronomers had seen something that looked a little like, but wasn’t, a supernova. Now the longer photographic exposures, with more powerful clusters of telescopes hooked together, showed that there was indeed some low-level radiation going on that positively had not been there in earlier studies of the same area. Attention turned to the tugs that were gradually herding all seven of the racing yachts into safe orbits—the six that were unharmed as well as the ball of crumpled fabric that had been Natasha’s Diana. Attention turned to all the world’s capitals and major cities, not one of which lacked a collection of “experts” capable of endlessly discussing what was going on—without ever increasing anyone’s understanding of it.

And then the phone started ringing. It got no better the next day, nor the day after that.

The last thing Myra Subramanian wanted to do was let her one remaining child out of her sight, but when she and Ranjit talked it over, they agreed that it would be even worse to upset Robert any more than he had been upset already. That next day was a Sunday. On Sundays, Robert went to Sunday school. This Sunday was no different—though Myra sat in an empty room nearby during the whole time that Robert, like the other handicapped children in the church’s special group, listened politely as the woman who was the assistant pastor read them Bible stories and they colored the line drawings of what the little girl next to Robert called “Jesus Christ on a crisscross.” And on Monday there was the workshop that one of their advisers had thought Robert would enjoy. There, Robert Subramanian—the boy who had discovered hexominoes for himself!—patiently and apparently pleasurably learned how to fill a decorative pencil box with one of each color of crayon, for sale in the workshop’s little gift store.

At least Robert’s crying was over. The worry, the puzzlement, the terrible pain of loss, however—they weren’t over for either Myra or Ranjit. The calls never stopped coming in, either, from everyone they knew, and from an unbelievable number of people they didn’t know at all. Some were actual pests. Ronaldinho Olsos, for instance, begging their forgiveness in case they felt he was in any way responsible; T. Orion Bledsoe, from Pasadena, to offer cursory sympathy but mostly to ask if Ranjit had any idea, any idea at all that for any reason he hadn’t already communicated to the authorities, of what might have happened to his daughter.

Then there were the reporters.

Ranjit had believed that the absolute maximum invasion of his privacy had taken place after Nature had published his proof of Fermat’s Last Theorem. He was wrong about that. What happened now was much worse. Although President-Elect Bandara had arranged for police to guard the approaches to the Subramanian home, they were effective only there and nowhere else. Once Ranjit got onto his bike to leave, he was fair game. So he didn’t go into his university any more often than was unavoidable. After dinner he left Myra studying her journal reports and Robert stacking marbles on the floor beside her and retreated to the master bedroom to plan his next seminar.

That was when it happened.

Myra looked up from her screen, frowning. She had heard something—a distant electronic squeal, perhaps—and at the same moment had seen a flash of golden light coming under the door.

The next thing she heard was her husband’s voice, his tone a mixture of joy and terror. “My God!” he cried. “Tashy, is that really you?”

After that there was nothing that could have kept Myra de Soyza Subramanian out of that room. When she flung the door open, she saw her husband staring at someone standing by the window. It was a young woman. What she wore was the bare minimum that any girl might wear who knew perfectly well that no outside party was going to see her.

It was a costume Myra had often enough seen her daughter wear around the house. She echoed her husband’s cry—“Tashy!”—and did what any mother might have done in these preposterous circumstances, threw herself at the girl, trying to wrap her arms around her.

That, it turned out, was impossible.

A meter from the figure of the girl something slowed Myra down, a dozen centimeters later it stopped her cold. It wasn’t anything like a wall. It wasn’t anything tangible at all. Perhaps one could say that it was something like a warm and irresistible breeze.

Whatever it was, Myra was stopped cold, right there, at arm’s length from any part of this figure that wore the face of the child she had borne, and raised, and loved.

And who now did not even look at her. Its eyes were fixed on Ranjit. When it spoke, it said, “It is not of interest to discuss who I am, Dr. Subramanian. What is important is that I must ask you many questions, all of which you must answer.”

And then, without waiting for a response from Ranjit, without any explanations or even simple courtesy, the questioning began.

“Many” questions?

Yes, that was definitely the right word. They went on forever—for, by actual clock time, nearly four hours—and they covered, well, everything. “Why are many of your tribes destroying their weapons?” “Has your species ever lived at peace?” “What is the meaning of ‘proof’ as applied to your earlier researches on the Fermat theorem?” And even stranger ones: “Why do your males and females often copulate even when the female cannot conceive?” And “Have you not calculated an optimal population for your planet?” And “Why do your actual numbers so greatly exceed it?” And, “There are areas of many square kilometers on your planet that have very small human populations. Why have you not resettled some of your people there from crowded urban areas?”

Through it all, Myra stood there, frozen. She could see everything. She couldn’t move. She saw, and yearned to help, her husband’s struggles to deal with the interrogation in spite of his own helpless bafflement.

And such questions! “Sometimes,” she—or it—was asking, in that uninflected voice that might have come from a reanimated corpse, “the word you use for an assemblage of humans is ‘country’ and sometimes ‘nation.’ Are the two concepts differentiated by, perhaps, size?”

The figure’s putative father shook his head. “Not at all. There are some countries with as few as some hundreds of thousands of inhabitants and some—China, for instance—with nearly two billion. But they’re both sovereign states—nations, that is,” he corrected himself.

The figure was silent for a moment. Then, “How was the decision made to annihilate the electronic capabilities of the nations, countries, or sovereign states of North Korea, Colombia, Venezuela, and others?”

Ranjit sighed. “By the council of Pax per Fidem, I suppose. You’d probably have to ask one of them for a more reliable answer—Gamini Bandara, say, or his father.” When the figure was silent again, he added nervously, “Of course, I can speculate. Would you like me to do that?”

The eyes that were not Natasha’s eyes regarded him for a long moment. Then the figure said, “No.” There was an ear-piercing electronic squeal, and a quick stir in the air, and the figure was gone.

Myra could move again, and did. She ran to her husband’s side and threw her arms around him. They sat silent, hugging each other, until a banging at the front door startled everyone. When the maid answered it, at least a dozen police came racing in, looking for something to arrest. The captain, out of breath, panted, “Sorry. The duty constable saw what was happening through a window and alerted us, but when we got here, we just couldn’t get close to the house. Couldn’t even touch the wall—Excuse me.” He lifted his own screen to his ear, while Myra was assuring the police, diligently searching every part of the house, that none of them had been harmed.

Then the police captain replaced his pocket screen on his belt. “Dr. Subramanian? Did you mention Gamini Bandara, the president-elect’s son, in your conversation with that—” He stopped, searching for the right noun to complete the sentence and not finding it. “With that,” he finished.

Ranjit nodded. “Yes, I think I did.”

“I thought so,” the cop said heavily. “Now he’s getting the same kind of questioning you were, from the same person.”

All of that news went out to every human being who owned or had access to a screen. It did not give much understanding to anyone, though. Not to what was left of the Subramanian family, nor to the rest of the human race. Not even to the horde of One Point Fives who hung trapped in their troop transports, drifting through the Oort cloud.

Those beings had concerns much more immediate than those of the human race. To the One Point Fives it was all very well to be ordered to postpone their annihilation of the human race, but the orders the Grand Galactics had handed down did not seem to take full cognizance of what obeying those orders entailed.

It was a question of numbers. Some 140,000 One Point Fives had originally boarded the transports. That number had not changed for more than a dozen years. But then, unwilling to die without descendants to carry on their genetic line, the One Point Fives had given themselves the luxury of that brief and violent flurry of sexuality.

The results of that orgy had already been born. Indeed, they now were nearly fully adult….

But the armada had not been equipped to keep so large a number alive for a prolonged period.

The mechanical replenishers that had been built to supply air, water, and food for 140,000 One Point Fives had been forced to cope with nearly twice that number. Now they were beginning to crumble under that stress. Soon there would be shortages. Soon after that, deaths.

And what were the Grand Galactics going to do about that?
