“It isn’t,” Leitz was quick to say. “It was, but it’s not now. The colony had been active for more than a year before the so-called city was found. It was overgrown to such an extent that it was virtually invisible from the air. Nothing else has shown up, in spite of increased probe activity. The people at Base Three found not the slightest evidence of recent habitation, until …” He stopped.

“Until Bernal was murdered,” Matthew finished for him.

“By one of his colleagues,” Leitz said, stubbornly. “The killer may have used a weapon tricked up to look like a local product, but it musthave been a human hand that wielded it. The people at Base Three seem to be determined not to carry out a full and proper investigation of their own, so we had no choice but to wake Inspector Solari.”

Matthew was still puzzled. “Are you implying that the people Bernal was working with are running some kind of scam?” he asked. “You think they’re pretendingthat he was killed by aliens? Why?”

Leitz’s discomfort deepened yet again. “I don’t know,” he said, defensively. “But there are certainly people at Base One who’ve added the possible continued existence of the aborigines—however unlikely the possibility may be—to the list of reasons why Professor Lityansky should never have initiated the landings. The people who want to withdraw from the planet are desperate for any justification they can find.”

“So why not let the ones who want out withdraw? Wouldn’t it be better to have a colony of committed volunteers than one whose members are fighting among themselves?” Matthew thought that he already knew the answer to that one, but he wanted to see Leitz’s response.

It was, as he’d anticipated, almost explosive. “But that’s the one thing we can’tdo!” the youth exclaimed. “If the colony is to be viable, it will eventually need the full repertoire of the skills possessed by the cargo—and even if one member of each notional pair decided to stay, that would still leave the colony with a dangerously depleted gene pool. It’s absolutely vital that they allaccept the necessity of making the colony work. You must see that, Professor Fleury. You must.”

Must I?Matthew thought.

Vince Solari’s interest in genomics was limited, and he obviously wanted to get back to more immediate concerns. Matthew’s reluctance to endorse Leitz’s categorical imperative gave him the opportunity to butt in. “Why is the guard in the corridor wearing a gun, Mr. Leitz?” he asked, bluntly. “In fact, why should anyoneaboard the ship be wearing a gun?”

Frans Leitz colored, but the greenish tint in his skin lent the blush a peculiar dullness. “It’s purely a precaution,” he said.

“I figured that,” Solari came back. “What I want to know is: against what?”

“There have been … policy disagreements concerning the administration of the ship and the control of its resources,” the boy admitted. “I’m really not competent to explain the details—I’m just a medical orderly, and a trainee at that. The captain will tell you everything. But it really is a precaution. No one on the ship has been injured, let alone killed, as a result of the … problem.”

“But who, exactly, is the precaution intended to deter?” Mathew said, modifying Solari’s question slightly without softening the insistence of the demand. “Are we talking about mutineers, or what?”

“I suppose so,” the boy replied, steadfastly refusing to elaborate—but he must have read in Vince Solari’s eyes that he wouldn’t be let off so easily. “The captain will tell you all that. He can explain it far better.”

“I’m sure he can,” Matthew said, drily, “but …”

Frans Leitz had had enough. “Eight-zero,” the boy said, as he turned to flee from the uncomfortable field of discussion. “Before you go,” Solari was quick to say, “can you give us a quick introduction to the equipment by our beds. There’s so much we need to know that the sooner we can make a start ourselves the better equipped we’ll be to ask questions of the captain.”

Leitz hesitated, but he had no grounds for refusal—and he knew that if he were busy lecturing the two of them on basic equipment skills he could probably override more awkward questions with ease.

“Sure,” he said, only a little less warmly than Matthew could have wished.

FIVE

When the first picture of the new world came up on the wallscreen Matthew caught his breath. He had thought himself more than ready for it, but the reality still took him by surprise.

The image reminded him, as he had expected, of the classic twentieth-century images of the Earth as seen from the moon, but the differences leapt out at him much more assertively than he had imagined. The new world’s two moons were much smaller and closer than Earth’s, and they were both in the picture, which had obviously been synthesized from photographs taken from Hopewhile she was much further away than her present orbit.

The second thing Matthew noticed, after absorbing the shock of the two moons, was the similarity of the clouds. It was as if his mind were making a grab for something reassuring, and that it was able to take some comfort from the notion that the old Earth and the new were clad in identical tattered white shirts.

But everything else was different.

The land masses were, of course, completely different in shape, but that was a trivial matter. The strikingdifference was a matter of color. Matthew, having been forewarned, was expecting to see purple, but he had somehow taken it for granted that it would be the land rather than the sea that would be imperial purple, and it took him a moment or two to reverse his first impression.

Even at its most intense, the purple of this world’s land-based vegetation was paler than he had expected. It seemed somehow insulting to think in terms of mauveor lilac, although those shades were certainly the most common. So vague and careless had Matthew’s anticipations been that he had not factored in the oceans in at all, and would not have been at all surprised to find them as blue as Earth’s. They were not; they were gloriously and triumphantly purple, more richly and stridently purple than the land.

Matthew remembered that the first aniline dye to be synthesized from coal tar in Earth’s nineteenth century had been dubbed Tyrian purple. That, presumably, was why Tyre had been added to the list of potential names for “the world.” The murex, he supposed, must have been the source of the imperial purple of Rome, and there were probably mollusk-like creatures of a similar sort in the purple oceans of the new world, but Murex did not sound quite right to Matthew as the name of a world. Tyre and Ararat seemed somehow far more fitting.

Matthew might have paused for a while to wonder whether the oceans were so richly purple because they were abundantly populated by photosynthetic microorganisms and algae, or because of some unexpected trick of atmospheric refraction, but his companion had the keyboard and Solari was already racing ahead in search of more various, more intimate, and more detailed views, while Frans Leitz looked on approvingly. The former hypothesis, Matthew decided en passant, seemed more likely as well as more attractive—but so had the hypothesis that DNA would always be selected out by the struggle to produce true life from mere organic mire.

“Can you find a commentary?” Matthew asked.

Solari shook his head. “None available. I guess they haven’t had time to add the voiceovers yet.” He glanced at Leitz as he spoke.

“We didn’t think a commentary was required,” the crewman said.

Other surprises followed as the mute viewpoint moved a little closer to the surface. Matthew had not been expecting the desert areas to be so silvery, or the ice caps so neatly star-shaped. He saw both ice caps as the synthesized image rotated about two axes, always presenting a full disk to the AI-eye.
