“If you hadn’t been a kid,” Matthew told him, leaning back against his bed so as to take some of the weight off his aching feet, “you’d have understood that I was never the kind of prophet who could take delight in saying I told you so. I knew what the chiasmalytic transformers might do—what they were madeto do—but I never relished the thought.”

“Made to do? I remember you as a bit of a ranter, but I didn’t have you pegged as a conspiracy theorist. The official line always said that the seetees were Mother Nature’s ultimate backlash—Gaea’s last line of self-defense. The idea that they were a final solution cooked up in a lab was supposed to be a neohysteric fantasy.”

Matthew winced slightly at the casual suggestion that he had been a bit of a ranter, although people had called him a lot worse things. “It matters not whence Nemesis comes,” he said, recalling another of his not-so-classic sound bites as if it had only been yesterday when he had last deployed it. “It only matters where she goes.”

“They might have found a cure after I was frozen down, I guess,” Solari said, pensively. “We ought to look that up, oughtn’t we? We’ve got a lot of history to catch up on.”

“And not enough time,” Matthew said. “Not until we’re down on the surface, at any rate, and probably not then. Still, it looks as if your job won’t be as hard as it might have been, so you might be able to get back to your homework fairly soon.”

“Seven suspects,” Solari mused, lifting the keypad up to his face and studying the layout of the keys with minute care. “Eight if you count the hypothetical alien. It doesn’t sound too difficult—but I’ll be way too late to get much from the crime scene. Until I have the facts …”

“If the murderer isan alien,” Matthew observed, “I don’t suppose we’ll attempt to bring him to trial. The discovery would be far more momentous than any mere murder. The greatest discovery ever—and they seem almost determined not to make it. Maybe the crew don’t quite understand, but the people fresh from the freezer … I can’t understand theirattitude at all.”

Solari obviously didn’t share Matthew’s wonderment. “Do you want to go on playing tourist flyby,” he asked, “or shall I try to find something more interesting?”

“Try to find something more interesting,” was Matthew’s vote. He had seen enough purple vegetation for the time being.

As yet, though, Solari wasn’t sufficiently familiar with the equipment to be able to exit from the image-catalog, and he stopped trying when the sequence moved on to animal life.

In the absence of any oral explanation it was difficult to determine the principles according to which the images had been filed and organized, but the first impression formulated in Matthew’s mind was that the new world was improbably rich in soft-bodied invertebrates. He couldn’t remember exactly what a murex looked like, but there was such a wealth of sluglike, clamlike and snaillike creatures among the images on the screen that he figured that there had to be a murex-analogue in there somewhere.

The worms were even more multitudinous, but worms were fundamentally boring, and Solari kept his thumb on the button that fast-forwarded through that section of the array before slowing down to take a closer look at various entities that seemed more interestingly chimerical.

“What’s that?” Solari demanded, finally making use of his discovery of a pause function. He obviously thought that Matthew, being a biologist of sorts, ought to have been able to master the fundamental taxonomy of the local ecosphere by courtesy of the hectic sequence of glances he had laid on.

“I’ve no idea,” Matthew confessed. The creature in question looked like a cross between a giant liver fluke and a sea anemone, but he was biologist enough not to want to issue a description of that crude kind. The image was a film clip, which showed the creature gliding along like a snail, but the tentacles sprouting from its humped back remained limp and it wasn’t possible for Matthew to come to a firm decision as to their function. “It’s not very big,” he pointed out. “The scale on the baseline puts it at twenty or thirty centimeters from end to end.”

More film clips followed, slowly working up to images of more complex creatures. Eventually, Matthew supposed, they would reach fishy things, amphibians and other vertebrate-analogues, but he was not sure how many orders of invertebrates they might have missed. Were there really so few arthropod-analogues?

“How about thatone?” Solari followed up, this time pointing at something that looked rather like a translucent horseshoe crab. Matthew wondered whether the impression that the creatures he was seeing were soft-bodied might be an illusion born of their mauve coloration, but when this one began to move—more rapidly than he had expected—he judged that the outer tegument was too flexible to qualify as a “shell.”

Solari had to scroll through many more quasi-molluscan and vermiform organisms of widely varying dimensions before the tape reached creatures that had any sort of backbone, but he got there in the end. The analogies between these creatures and their Earthly equivalents were so obvious that Matthew’s faith in convergent evolution was soon restored. Although the new world’s Gaea-clone hadn’t been able to select out DNA as champion coding-molecule, she obviously knew lots of ways to design a perfectly adequate fish. There were things like mudskippers and land-going tadpoles, polished snakes and glassy froglike forms.

Even after an hour’s trawling, though, Matthew hadn’t seen much that could pass for fur and feathers. Even the local rat-analogues seemed to be naked. Unless they had contrived to miss out on the relevant folder, bird-and mammal-analogues were rare. And yet, there had been enough lemuroids around to produce humanoids, and enough humanoids to produce a race of city-builders that might have been alive and active when Mitochondrial Eve was mothering the entire human race.

One thing that Matthew didn’t see while the parade continued was any immature organisms: no nests, no eggs, no infants. Even when there were shots of entire herds of grazers, there was no sign of any young. Nor, for that matter, could he see any sign of secondary sexual characteristics on the adult organisms. In the absence of a commentary, however, he was reluctant to take these apparent absences at face value.

“There must be somereal animals,” Solari complained, meaning that there ought to be more mammal-equivalents.

“There ought to be some quasi-arthropodans too,” Matthew said. “Even if this world’s tacit planner didn’t have the same fondness for beetles as ours, there’d be no sense in missing out on a whole range of viable adaptive forms. Insects are among the most efficient products of Earthly evolution. If the rats had crashed out with the humans, the cockroaches would have inherited the Earth.”

“I can do without spiders, myself,” Solari told him. Matthew didn’t want to insult him with the pedantic insistence that arachnids weren’t insects, so he let the comment pass.

It eventually turned out, though, that there were a few monkey analogues and even a few flying creatures, although they were more like furless bats and flying squirrels than birds. Natural selection on Ararat-Tyre didn’t seem to have come up with hair or feathers, although it had just about mastered scales.

Solari breathed a deep sigh of satisfaction when he found the monkey-analogues, as if they had always been the only worthy objects of his search. They were pale purple, just like everything else, but they didn’t seem as conspicuously alien as the vegetation that surrounded them. Indeed, they seemed quaintly familiar, save only for the fact that they had no young, nor any sign of the kinds of fleshly apparatus employed by Earthly mammals to produce and nurture young.
