To make the whole thing even more messy looking, the main cylinder and its auxiliaries were pocked with globes, tubes and blisters, looking for all the world like budding yeast under a microscope. Like Topsy, the successful tradeship just
grew
, adding a cylinder here, a globe there, a blister in another place, as the ship's fortune waxed. In deep space, where friction was no factor, this wild messiness was a status symbol, a sign of prosperity.
Now, Maxwellian ships were coming and going constantly, bringing thorium, food, water, scientists. They had one great navigational hazard to overcome. Four mile-long spars sprouted from amidships on the main cylinder. During acceleration away from a sun, or deceleration towards a sun, four immense triangles of ten-molecule-thick plastic would stretch from the spars, catching the energy of photon packets outward bound from light sources. By grams per-square-yard, the solar sails provided negligible thrust, but cumulatively, over two square miles of surface area, they were good for a steady, if mild acceleration. Besides, the energy they provided was free.
But now, since the spars were empty, and the ship was spinning about its central axis, the spars were the arms of a monstrous windmill, which the Maxwellian ships had to avoid.
Captain Reed smiled as he watched the ships thread their way gingerly toward the
Outward Bound
. No doubt, there were simple ways of making the spars stationary while the ship spun, perhaps using the same circle-in-circle bearings that served to immobilize the conning globe. But no starship
he
had ever heard of had bothered to try. It was just too amusing watching the planethogs dodge the whirling spars.
Well, this would be the last day they'd have to brave the whirlwind. The last of the thorium was aboard, the Maxwellians had their force field and hot-cold technique, and Ching would be coming aboard on the last ship.
None too soon, either, thought Peter Reed. Ben Ezra will be here in another ten days. Ten days to get here, perhaps a week or two to break Horvath. Captain Reed had few illusions about
that
individual. Within three weeks, at the outside, Jacob ben Ezra would know that Ching pen Yee was aboard the
Outward Bound
.
Ben Ezra would be able to close the gap to a week or less, at the next planetfall, Nuova Italia, only ten light-years away.
But by that time, thought Reed, I'll know whether Ching's worth keeping. If he isn't, ben Ezra can have him at Nuova Italia. But if he is . . . well, ben Ezra will probably have to take on supplies at Nuova Italia. We can get away from him once more, if we have to. But . . . he can catch us easily, and wherever we head, he can be there before us, with us only having a couple of days lead.
We'll jump off that bridge when we come to it, thought Captain Reed.
"Dr. Ching is aboard," came a voice from the communicator.
"Good," said Reed. "How soon can we break orbit?"
"Everything'll be secured in another three hours, Dad."
"Roger!"
"Sorry, sir."
"All right, Roger," said the old man. "Make ready to break orbit as soon as possible. And send Ching to the reception room. Have Olivera there, too. In fact, stall Ching a bit, and have Manny get there a few minutes earlier. Tell him I'll be right down."
"Yes,
sir
."
"But, Peter," said Manuel Olivera, his dark eyes raised to the ceiling in supplication, "I am
not
a theoretical physicist. I am
not
a mathematician. I am a tinkerer, a librarian, a maker of stinks, a—"
"Manny! Manny! Please!" said the captain. "I know the whole song and dance by now. Nevertheless, you
are
the
Outward Bound
's chief scientist."
"Yes, yes," said the small dark-skinned man excitedly, "but you know as well as I do that all that means is that I'm a glorified librarian. We—"
"All right, all right. All I want you to do is
be
here, and pay attention. This Dr. Ching has something of value, I'm
sure
of it. And we may not have him very long. We've got to be quick, and—" "Dr. Ching pen Yee to see you, captain," said an orderly.
"Send him in."
Dr. Ching was a small, though well-built man of about sixty. His straight black hair was parted neatly in the middle. Only his shifting eyes betrayed his nervousness.
"Thank you for accepting my passage, Captain Reed," he said.
"Not at all, Dr. Ching. Frankly, we hope you may be of value to us. As you know, the lifeblood of a tradeship is knowledge. We sell it, and we buy it. To be blunt, we have
bought
you from Maxwell. You get passage with us, for as long as you want, and in return, we expect you to share your knowledge."
"But, captain," said Ching nervously, "I am a mathematical physicist. You are engaged in the business of selling practical technological knowledge. We mathematical physicists are not noted for producing marketable knowledge."
Reed frowned. This Ching was cool, and he was scared. A tough combination to crack.
"Please let Mr. Olivera and myself be the judge of that. By the way, I believe I've forgotten to introduce you. This is Manuel Olivera, our chief scientist."
"How do you do, Mr. Olivera," said Ching smoothly. "Captain Reed, really you are wasting your time. I am purely a theorist."
Reed wondered if he should spring his knowledge of Admiral ben Ezra's pursuit. He decided it could wait. "Suppose you just tell us what you're working on?" he said.
Ching fidgeted. "Mathematical theory," he said.
"Come now, Dr. Ching," snapped Olivera, "we are not complete scientific ignoramuses, you know. What sort of theory?"
"A development of a small corollary to the Special Theory of Relativity."
"Oh?" said Olivera. "Involving what?"
Ching's eyes flickered from focus to focus like a bird's. "Involving . . . some work with transfinite substitutions," he said vaguely.
Olivera continued his pursuit. "Transfinite substitutions? Where? For what?"
Ching laughed falsely. "Really, Mr. Olivera," he said. "It's all a complicated mathematical exercise. It amuses me to substitute infinite and transfinite numbers for some of the variables. As I said, nothing practical."
"Just why are you doing this?" snapped Olivera.
"Really," said Ching blandly, "that's an unanswerable question. Indeed. Why do men climb mountains? Because they are there. Really, gentlemen, I'm quite tired. May I be excused?"
Olivera was about to continue his sortie, but the captain waved him off.
"Of course," he said. "We will soon be leaving for Nuova Italia. In about two hours. We will have time to talk again, before we all go into Deep Sleep. By all means, rest up."
"Thank you, captain," said Ching. An orderly was called, and he led Ching off.
"Well, Manny?" asked the captain.
"Well,
what?
Am I a mind reader? Gibberish. Vagueness. Perhaps outright lies. I ask you, Peter, would Jacob ben Ezra travel fifty light-years after someone engaged in 'a complicated mathematical exercise?' Would Earth give a damn?"
"Of course not," said the captain.
"Then why in space didn't you tell him that you knew ben Ezra was after him?" snapped Olivera.
Peter Reed smiled thinly. "Time enough for that between now and Deep Sleep. That's a whole week. I think the strategic time to spring it is just before he goes into Deep Sleep. Impending Deep Sleep makes a man realize just how dependent he can be."
"You'd
better
loosen him up by then," said Olivera, "because it's just possible that when we wake up, we'll find ben Ezra right on our tails."
A three minute burst on the huge reaction rockets kicked the
Outward Bound
out of orbit.
As she drifted slowly outward, the huge triangular photon sails were reeled out onto the mile-long spars, blotting out whole sectors of stars.
The pale, almost invisible, blue stream of the ion drive shot noiselessly, vibrationlessly out of the nozzles.
The
Outward Bound
was on her way to Nuova Italia.
During the next week, the ship would be secured, the automatic systems checked, re-checked, and finally given command of the ship. There would be a final course correction, and then the thousand men, women and children who made up the crew of the
Outward Bound
would go into Deep Sleep.
Deep Sleep was the technique that had given Man that insignificant portion of the Galaxy which he possessed. A starship could accelerate to nearly three-quarters the speed of light, but this took over a year, and, although it had been proven true that subjective time on a fast-moving starship
did
contract, as Einstein had predicted, the factor was still far too short. The spaces between the suns would still eat up lifespans.
Deep Sleep had been developed to deal with this dilemma. Partly it was a technique developed from yoga, partly it was simply a careful, controlled lowering of the body temperature, till life slowed down to the barest crawl. The elements of the technique had been known even before rudimentary spaceflight. But it took the technical integration of all the factors to make Deep Sleep an effective and relatively safe form of suspended animation, and to give Man the stars.
Peter Reed was getting disgusted. It was now time to go into Deep Sleep, and still no one had been able to get anything out of Ching. Clearly, the man was scared silly.
Well, thought Reed, maybe I can shock him out of it now.
He was standing in one of the Deep Sleep chambers.
The walls were lined with transparent plastic cubicles, coffin-sized, honey-combed with passages, through which liquid oxygen was passed.
Another of the ship's economies, thought the captain. The same oxygen that served as the ship's air supply was cooled by the cold of space, and used to freeze the Deep Sleep chambers. It took a lot of liquid oxygen, in fact, the entire ship's supply, but since no one would be needing it while the crew was in Deep Sleep, and since it was re-usable, it made a neat saving.
Most of the crew were already in Deep Sleep. The cubicles were filled with frozen crewmembers, the Environment Masks snugly fitted over their faces. Only the skeleton Deep Sleep detail, the captain and Dr. Ching remained unfrozen. Now, the captain and the passenger would take their places, and then the automatics would handle the Deep Sleep detail.
A crewman was escorting Ching to his cubicle. The mathematician's face was pasty and pale. His eyes flickered furiously over the frozen figures in the plastic coffins.
Reed smiled, half in sympathy, half in satisfaction. He had spent a total time of nearly seven hundred years in those cubicles. Still, it always made him shudder a bit. But Ching had only experienced Deep Sleep once, and somehow, the second time was always the hardest.
"Well, Dr. Ching," he called out, "how do you feel?"
"A bit foolish, captain. I must admit that I am afraid, and yet there is really nothing to be afraid of."
For a moment, Reed's distaste for Ching was washed away. The Grand Admiral of Earth's fleet had hounded him across fifty light-years, and now he was facing what must to him be a great irrational fear. And yet, he's so calm.
"I don't see why a man like
you
should be afraid," said the captain deliberately, hating what he was doing.
"Captain?"
"Well, it seems to me that a man who's being chased across the Galaxy by Jacob ben Ezra, and still refuses to tell me
why
, must have a surplus of guts."
For a moment, Ching trembled. Then he smiled slowly. "I
thought
you knew," he said. "Why else would you be so interested in me?"
"Why don't you tell me what this is all about, Ching? What are you on to? Why is Earth so concerned? I don't expect you to believe that we're your
friends
, but surely you must realize that it's in our interest as traders to protect you if you're working on something important."
Ching sighed heavily. "Captain Reed," he said, "Earth is not after me because they
want
what I'm working on. I'm really not working on anything practical at all. Just a mathematical and physical concept."
"And yet, they're chasing farther than they've ever chased a fugitive before."
"Yes," said Ching. "Captain, some day you may know why I must keep my secret. If Jacob ben Ezra catches up to us, you will be
glad
that I've remained silent."
"Why, man, why?"
"Because," said Ching, "I'm fairly certain that ben Ezra has orders to kill anyone who knows what I know."
The captain frowned. "Perhaps you will change your mind when we come out of Deep Sleep at Nuova Italia."
"Perhaps, captain,
you
will change
yours
."
Peter Reed shrugged irritably. "Let's get on with it," he said to the attendant.
He climbed into his cubicle, and settled himself on the foam-rubber mattress. The attendant secured him with clamps. The ship's spin would stop when the crew was in Deep Sleep. There would be no gravity.
The soft, lined mask was fitted over his face. He inhaled the soothing tranquilizer vapor. He was comfortable, content. He vaguely felt the prick of a needle, then his senses began to dull, first sight, then sound, then feel, then smell. The last sensation was a dry taste in his mouth, and then that was gone, and he was an entity within himself, in his own private universe . . . a mote swimming in the sea of himself . . . and then, even the sense of mind began to dull . . . to fade . . . to softly melt away, like a mouthful of cotton candy.
A blinding redness which pervaded the universe . . . a pins-and-needles feeling . . . then warmth, overwhelming, welcome warmth, motion, smell, sound.
Jacob ben Ezra sat up in his Deep Sleep cubicle, slowly, patiently teaching his old eyes to focus.
You never get really used to it, he thought. What year is this? Let's see . . . Maxwell to Nuova Italia means fourteen years in Deep Sleep, and when we left Maxwell, it was 3297 A.D., or '98? On Earth . . .
Ben Ezra gave a dry little laugh. Time! What is time? Does it matter? I am eighty years old, I am eight hundred years old, or maybe a thousand.
