"Ah," said Morrison and caught Kaliinin's eye.

Very slightly, she shook her head. Very tentatively, a warning finger crossed her lips.

Morrison said, "Nothing to tell. I had vague sensations I couldn't describe in any objective way. It could well have been my imagination. Certainly those whom I tried to tell about it were convinced it was."

"And you never published anything about them?"

"Never. I merely mentioned it in passing at conventions and that was bad enough. If Shapirov and you heard of it, it was through word of mouth only. If I had published, that would have come as near to scientific suicide as I would ever want to be."

"Too bad."

Morrison looked briefly toward Kaliinin. She had nodded very slightly, but said nothing. Clearly, she couldn't say anything without being overheard by the entire ship.

Morrison looked around carelessly. Dezhnev was lost in his work, clucking to himself. Konev stared straight ahead, lost in whatever tortuous thoughts he happened to have. Boranova, behind Kaliinin, was studying the screen of her computer carefully and was making notes. Morrison did not try to read them - he could read English upside down, but he hadn't come to that pitch of ease with Russian.

Only Kaliinin, to his left, was looking at him.

Morrison pressed his lips together and then shifted his computer into a word-processing mode. It did not have a Cyrillic adjunct, but he spelled out the Russian words in phonetic Roman lettering. WHAT IS WRONG?

She hesitated, probably not very much at home in Roman.

Then her own fingers flashed and the neat Cyrillic on her screen read: DON'T TRUST HIM. SAY NOTHING. It was erased at once.

Morrison wrote: WHY?

Kaliinin said: NOT EVIL, BUT PRIORITY, CREDIT. WILL DO ANYTHING, ANYTHING, ANYTHING.

The words were gone and she looked away firmly.

Morrison considered her thoughtfully. Was it only the vengefulness of a woman betrayed?

It didn't matter, in any case, for he had no intention of talking about anything that he hadn't already given away, either in a paper or by word of mouth. He himself was not evil, but where priority and credit were concerned, he might not do anything, anything, anything, but he would do a great deal.

Still, there was nothing to be done at that moment. Or one thing, perhaps, which was completely aside from the point, but which was beginning, just beginning, to occupy his mind to the exclusion of other things.

He turned to Boranova, who was still staring at her instrument and tapping her fingers softly against the arm of her seat in thoughtful concentration.

"Natalya?"

"Yes, Albert?" She did not look up.

"I hate to introduce a note of ugly realism, but" - his voice lowered to near-soundlessness - "I'm thinking of urinating."

She looked up at him, a corner of her lips twitching very slightly, but avoiding the smile. She did not lower her voice. "Why think of it, Albert? Do it."

Morrison felt like a little boy raising his hand for permission to leave the room - unreasonably so, he knew. "I don't like to be the first."

Boranova frowned, almost as though she were the teacher in the case. "That is quite silly and, in any case, you are not. I have already taken care of such a need in myself." Then, with a faint shrug, "Tension tends to increase urgency, I have frequently found."

Morrison had frequently found that, too. He whispered, "It's all very well for you. You're there in the back seat alone." And he nodded slightly in the direction of Sophia.

"So?" Boranova shook her head. "Surely you don't wish me to improvise a curtain for you? Shall I place my hand over her eyes." (Kaliinin looked in their direction in surprise.) "She will ignore you, I'm sure, out of decency and out of a feeling that in short order she will wish you to ignore her."

Morrison was keenly embarrassed, for Kaliinin was now looking at him with obvious understanding. She said, "Come, Albert, I held you naked in my lap. What room need one make for modesty now?"

Morrison smiled weakly and made a little thank-you gesture.

He tried to remember how to manage the waste lid on his seat, but once he remembered, he found that it slid open with a small but definite click. (Those irritating Soviets! Backward always in small ways. It might easily have been designed to open noiselessly.)

He also managed to loosen the electrostatic seam along his crotch and then found himself worrying whether he would manage to close it unobtrusively afterward.

Morrison felt the current of air at the moment the waste lid opened and it felt uncomfortably cold against his bare skin. He sighed with a tremendous relief when he was done, then he managed to close the seal along the crotch and sat there, panting. He realized that he must have been holding his breath.

"Here," said Boranova brusquely. He stared, for a moment, at what she was holding, then recognized it as a small sealed towel. He tore open the seal, found the towel within moistened and scented and rubbed his hands with it. (The Soviets were learning small elegances, obviously - or decadences, depending on whether finickiness or impatience won the battle for domination within you.)

And then Dezhnev's throaty voice sounded loudly, very loudly, in Morrison's ear after all the whispering he had been engaged in. "That's done now."

"What's done?" asked Morrison angrily, automatically assuming the reference was to his bodily functions.

"The individual firing of the motors," said Dezhnev, making a there-you-are gesture with both hands in the directions of the ship's controls. "I can fire any one, or two, or all three, if I wish. Absolutely certain - I think."

"Which is it, Arkady?" said Boranova waspishly. "Is it quite certain or is it a matter of opinion?"

"Both," said Dezhnev. "It is my opinion that I am absolutely certain. The trouble is that my opinion isn't always right. My father used to say -"

"I think we ought to try it out," said Konev, cutting off Dezhnev's father, perhaps in the full realization he was doing so.

"Of course," said Dezhnev. "That goes without saying, but as my father used to say" - he raised his voice as though determined not to be again subverted - "the sure thing about anything that goes without saying is that someone is bound to say it. - And you might as well know -"

He paused momentarily and Boranova said, "What might we as well know?"

"Several things, Natasha," said Dezhnev. "In the first place, steering will take a lot of energy. I've done my best, but the ship is not designed for this. For another - well, I can't communicate with the Grotto now."

"Can't communicate?" said Kaliinin, her voice rising to a near squeak in what was either surprise or indignation.

Boranova's voice marked her as definitely indignant. "What do you mean, we can't communicate?"

"Come, Natasha, I can't wire up the motors separately without wires, can I? The best engineer in the world can't make wires out of nothing and can't manufacture silicon chips out of nothing, either. Something had to be dismantled and the one thing I could dismantle without disabling the ship was communications. I told them that out in the Grotto and there was a lot of shrieking and complaining, but how could they stop me? So now we can steer, I think - and we can't communicate, I know."

There was silence as the ship began to move. The surroundings were utterly different now. In the bloodstream, there had been a heaving medley of objects - some crawling ahead of the ship, some slowly drifting behind, depending on eddies and streamlining, Morrison supposed. There was the feeling of movement, if only because the markings on the walls - fatty plaques in the arteries, tiling in the capillaries, slipped steadily backward.
