with yellow spots. Ore deposits? The same material that tinted most airless bodies here? Tregennis was puzzled. You got dark spots in Solar-type systems. They were due to photolysis of frozen methane. Of course, this sun was so feeble…
It nonetheless illuminated the planet aft. Quarta's hue was pale rose, overlaid with silvery streaks that were ice clouds: crystals of carbon dioxide, ammonia, in the upper levels methane. No twists, no vortices, no sign of any jovian storminess marred the serenity. Though the disc was visibly flattened, it rotated slowly, taking more than 40 hours. Tidal forces through eons had worn down even the spin of this huge mass. They had likewise dispersed whatever rings it once had, and surely drawn away moons. The core possessed a magnetic field, slight, noticeable only because it extended so far into space that it snatched radio waves out of incoming cosmic radiation-remnant magnetism, locked into iron as that core froze. For gravitational energy release had long since reached its end point; and long, long before then, K-40 and whatever other few radionuclei were once on hand had guttered away beyond measurement. The ice sheath went upward in tranquil allotropic layers to a virtually featureless surface and an enormous, quietly circulating atmosphere of starlike composition. Quarta had reached Nirvana.
It fell ever farther behind. Fido closed in on Rover.
The ship swelled until she might have been a planet herself. Instructions swept back and forth, electronic, occasionally verbal. A boat bay opened its canopy. Yoshii maneuvered through and docked. The canopy closed, shutting off heaven. Air hissed back in from the recovery tanks. A bulb flashed green. Yoshii unharnessed, operated the lock, crawled forth, and walked under the steady weight granted him by the ship's polarizer, into her starboard reception room.
Laurinda waited.
Yoshii stopped. She was alone. White hair tumbled past delicate features to brush the dress, new to him, that hugged her slenderness. She reached out. Her eyes glowed. “W-welcome back, Juan,” she whispered.
“Why, uh, thanks, thank you. You're the… committee?”
She smiled, dropped her glance, became briefly the color of the world he had rounded. “Kam met Carita. As for you, Dorcas— Mate Saxtorph suggested—”
He took her hands. They felt reed-thin and silksoft. “How nice of her. And the rest. I've data discs for you.”
“They'll keep. We have more work than we can handle. Observations of Quinta were, have been incredibly fruitful.” Ardor pulsed in her voice. The outermost planet was a safe subject. “We think we can guess its nature, but of course there's no end of details we don't understand, and we could be entirely wrong—”
“Good for you,” he said, delighted by her delight. “I missed out on that, of course.” Transmissions to him, including hers, had dealt with the Quartan system exclusively; any bit of information about it might perhaps save his life. “Tell me.”
“Oh, it's violent, multi-colored, with spots like Jupiter's — one bigger than the Red — and the surface is liquid water. It's Arctic-like; we imagine continent-sized ice floes clashing together.”
“But warmer than Quarta! Why?”
“We suppose a large satellite crashed, a fraction of a million years ago. Debris formed the rings. The main mass released enough heat to melt the upper part of the planetary shell, and, and we'll need years, science will, to learn what else has happened.”
He stood for an instant in awe, less of the event than of the time-scale. That moon must have been close to start with, but still it had taken the casual orbital erosion of… almost a universe's lifespan so far — how many passages through nebulae, galaxies, the near-ultimate vacuum of intergalactic space? — to bring it down. What is man, that thou art mindful of him? What is man, that he should waste the little span which is his?
“That's wonderful,” he said, “but we—” Impulsively, he embraced her. Astoundingly, she responded.
Between laughter and tears she said in his ear, “Come, let's go, Kam's spread a feast for the two of us in my cabin.”
Set beside that, the cosmos was trivial.
Saxtorph's voice crackled from the intercom: “Now hear this. Now hear this. We've just received a message from what claims to be a kzin warship. They're demanding we make rendezvous with them. Keep calm but think hard. We'll meet in the gym in an hour, 1530, and consider this together.”
Standing with back to bulkhead, the captain let silence stretch, beneath the pulsebeat and whispers of the ship, while he scanned the faces of those seated before him. Dorcas, her Athene countenance frozen into expressionlessness; Kam Ryan's full lips quirked a bit upward, defiantly cheery; Carita Fenger a-scowl; Juan Yoshii and Laurinda Brozik unable to keep from glancing at each other, hand gripping hand; Arthur Tregennis, who seemed almost as concerned about the girl; Ulf Markham, well apart from the rest, masked in haughtiness — Ulf Reichstein Markham, if you please… The air renewal cycle was at its daily point of ozone injection. That tang smelled like fear.
Which must not be let out of its cage. Saxtorph cleared his throat. “Okay, let's get straight to business,” he said. “You must've noticed a quiver in the interior g-field and change in engine sound. You're right, we altered acceleration. Rover will meet the foreign vessel, with velocities matched, in about 35 hours. It could be sooner, but Dorcas told them we weren't sure our hull could take that much stress. What we wanted, naturally, was as much time beforehand as possible.”
“Why don’t we cut and run?” Carita asked.
Saxtorph shrugged. “Whether or not we can outrun them, we for sure can't escape the stuff they can throw, now that they've locked onto us. If they really are kzinti navy, they'll never let us get out where we can go hyperspatial. They may be lying, but Dorcas and I don't propose to take the chance.”
“I presume evasion tactics are unfeasible,” said Tregennis in his most academic voice.
“Correct. We could stop the engine, switch off the generator, and orbit free, with batteries supplying the life support systems, but they'd have no trouble computing our path. As soon as they came halfway close, they'd catch us with a radar sweep.
“From what data we have on them, I believe they were searching for some time before they acquired us, probably with amplified optics. That's assuming they were in orbit around Secunda when they first learned of our arrival. The assumption is consistent with what would be a reasonable search curve for them and with the fact that there are modulated radio bursts out of that planet-transmissions to and from their base.”
Nobody before had seen Yoshii snarl. “And how did they learn about us?” he demanded.
Looks went to Markham. He gave them back. “Yes, undoubtedly through me,” he said. Strength rang in the words. “You all know I took it upon myself to beam a signal at Secunda — in my capacity as this expedition's officer of the government. The result has surprised me, too, but I acknowledge no need to apologize. If we, approaching a kzin base unbeknownst, had suddenly become manifest to their detectors, they would most likely have blown us out of existence.”
Ryan nodded. “Without stopping to ask questions,” he supplied. “Yeah, that'd be kzin style. If they are. How're you so sure?”
“I think we can take it for granted,” Dorcas said. “Who else would have reason to call themselves kzinti?”
“Who else would want to?” Carita growled.
“Save the cuss words for later,” Saxtorph counseled. “We're in too much of a pickle for luxuries. I might add that although the vocal transmission was through a translator, the phrasing, the responses to us, everything was pure kzin. They are here — on the far side of human space from their own. You realize what this means, don't you, folks? The kzinti have gotten the hyperdrive.”
That conclusion had indeed become clear to everyone, but Laurinda asked, “How could they?” as if in pain.
Yoshii grimaced. “Once you know something can be done, you're halfway to doing it yourself,” he told her.
“I know,” she answered. “But I had the, the impression they aren't quite as clever at engineering as humans, even if they did invent the gravity polarizer. And, and wouldn't we have known?”
“Collecting intelligence in kzin space isn't exactly easy,” Saxtorph explained. “Anyhow, they may have done the R and D on some planet we aren't aware of. I'll grant you, I'm surprised myself that they've been this quick.
