in orbit about halfway between planet and moon. Wide field for radars, optics, every kind of gadget; quick access to either body. Kam heard as how that space is cluttered with industrial stuff and junk, but she’ll follow a reasonably clear path and keep ready to dodge or deflect whatever may be on a collision course.
“Now. The kzinti mine the asteroid belt for metals, mainly iron. They do that by shifting the bodies into eccentric orbits osculating Secunda’s, then wangling them into planetary orbit at the far end. Kam heard as how an asteroid is about due in, and the tug was taking station to meet it and nudge it into place. To my mind, ’asteroid’ implies a fair-sized object, not just a rock.
“But the tug was prospecting, Kam heard, when she was ordered to Prima. Afterward she didn’t go back to prospecting, because the time before she’d be needed at Secunda had gotten too short to make that worthwhile. However, since she was in fact called from the sun, my guess is that the asteroid’s not in need of attention right away. In other words, the tug’s waiting.
“Again, if I were in charge, I wouldn’t keep a crew idle aboard. I’d just leave her in Secunda orbit till Al ’s wanted. That needs to be a safe orbit, though, one and inner space isn’t for an empty vessel. So the tug’s circling wide around the planet, or maybe the moon. Unless she sits on the moon, too.”
“She isn’t able to land anywhere,” Ryan reminded. “Those cooling fins, if nothing else. I suppose the kzinti put Rover down, on the planet-facing side, the easier to keep an eye on her. She’s a lure for us, after all.”
Saxtorph nodded. “Thanks,” he said. “Given that the asteroid was diverted from close-in solar orbit, and is approaching Secunda, we can make a pretty good estimate of where it is and what the vectors are. How ’bout it, Laurinda?”
“The Kzinti are expecting the asteroid. Their instruments will register it. They’ll say, ’Ah, yes,’ and go on about their business, which includes hunting for us and never suppose that we’ve glided to it and are trailing along behind.”
Dorcas let out a war-whoop.
The thing was still molten. That much mass would remain so for a long while in space, unless the kzinti had ways to speed its cooling. Doubtless they did. Instead of venting enormous quantities of water to maintain herself near the sun, the tug could spray them forth. “What a show!” Saxtorph had said. “Pity we’ll miss it.”
The asteroid glowed white, streaked with slag, like a lesser sun trundling between planets. Its diameter was ample to conceal Shep. Secunda gleamed ahead, a perceptible tawny disc. From time to time the humans had ventured to slip their boat past her shield for a quick instrumental peek. They knew approximately the rounds which Vengeful Slasher and Sun Defter paced. Soon the tug must come to make rendezvous and steer the iron into its destination path. Gigantic though her strength was, she could shift millions of tonnes, moving at kilometers per second, only slowly. Before this began, the raiders must raid. Saxtorph made a final despairing effort: “Damn it to chaos, darling, I can’t let you go. I can’t.”
“Hush,” Dorcas said low, and laid her hand across his mouth. They floated weightless in semi-darkness, the bunk which they shared curtained off. Their shipmates had, unspokenly, gone forward from the cubbyhole where everyone slept by turns, to leave them alone.
“One of us has to go, one stay,” she whispered redundantly, but into his ear. “Nobody else would have a prayer of conning the tug, and Kam and Laurinda could scarcely bring Rover home, which is the object of the game. So you and I have to divide the labor, and for this part I’m better qualified.”
“Brains, not brawn, huh?” he growled half resentfully.
“Well, I did work on translation during the war. I can read kzin a little, which is what’s going to count. Put down your machismo.” She drew him close and fluttered eyelids against his. “As for brawn, fellow, you do have qualifications I lack, and this may be our last chance… for a spell.”
“Oh, love—you, you—”
Thus their dispute was resolved. They had been through it more than once. Afterward there wasn’t time to continue it. Dorcas had to prepare herself.
Spacesuited, loaded like a Christmas tree with equipment, she couldn’t properly embrace her husband at the airlock. She settled for an awkward kiss and a wave at the others, then closed her faceplate and cycled through.
Outside, she streaked off, around the asteroid. Its warmth beat briefly at her. She left the lump behind and deployed her diriscope, got a fix on the planet ahead, compared the reading with the computed coordinates that gleamed on a databoard, worked the calculator strapped to her left wrist, made certain of what the displays on her drive unit meters said right forearm—and set the thrust controls for maximum. Acceleration tugged. She was on her way.
It would be a long haul. You couldn’t eat distance in a spacesuit at anything like the rate you could in a boat. Its motor lacked the capacity—not to speak of the protections and cushionings possible within a hull. In fact, a large part of her load was energy boxes. To accomplish her mission in time, she must drain them beyond rechargeability, discard and replace them. That hurt; they could have been ferried down to Prima for the saving of Carita and Juan. Now too few would be left, back aboard Shep. But under present conditions rescue would be meaningless anyway.
She settled down for the hours. Her insignificant size and radiation meant she would scarcely show on kzin detectors. Occasionally she sipped from the water tube or pushed a foodbar through the chowlock. Her suit took care of additional needs. As for comfort, she had the stars, Milky Way, nebulae, sister galaxies, glory upon glory.
Often she rechecked her bearings and adjusted her vectors. Eventually, decelerating, she activated a miniature radar such as asteroid miners employ and got a lock on her objective. By then Secunda had swollen larger in her eyes than Luna over Earth. From her angle of view it was a scarred dun crescent against a circle of darkness faintly rimmed with light diffused through dusty air. The moon, where Rover lay, was not visible to her.
Saxtorph’s guess had been right. Well, it was an informed guess. The warship orbited the planet at about 100,000 klicks. The supertug circled beyond the moon, twice as far out. She registered dark and cool on what instruments Dorcas carried; nobody aboard. Terminating deceleration, the woman approached.
What a sight! A vast, brilliant spheroid with flanges like convulsed meridians; drive units projecting within a shielding sheath—no ports, but receptors from which visuals were transmitted inboard; recesses for instruments; circular hatches which must cover steam vents; larger doors to receive crushed ice—How did you get in? Dorcas flitted in search. She could do it almost as smoothly as if she were flying a manwing through atmosphere.
There—an unmistakable airlock. She was prepared to cut her way in, but when she had identified the controls, the valves opened and shut for her. Who worries about burglars in space? To the kzinti, Rover was the bait that might draw humans.
The interior was dark. Diffusion of her flashbeam, as well as a gauge on her left knee, showed full pressure was maintained. Hers wasn’t quite identical; she equalized before shoving back her faceplate. The air was cold and smelled musty. Pumps muttered.
Afloat in weightlessness, she began her exploration. She’d never been in a kzin ship before. But she had studied descriptions; and the laws of nature are the same everywhere, and man and kzin aren’t terribly unlike—they can actually eat each other; and she could decipher most labels; so she could piecemeal trace things out, figure how they worked, even in a vessel as unusual as this.
She denied herself haste. If the crew arrived before she was done, she’d try ambushing them. There was no point in this job unless it was done right. As need arose she ate, rested, napped, adrift amidst machinery, Once she began to get a solid idea of the layout, she stripped it. Supplies, motors, black boxes, whatever she didn’t think she would require, she unpacked, unbolted, torched loose, and carried outside. There the grapnel field, the same force that hauled on cosmic stones, low-power now, clasped them behind the hull.
Alone though she was, the ransacking didn’t actually take long. She was efficient. A hundred hours sufficed for everything. “Very well,” she said at last; and she took a pill and accepted ten hours of REM sleep, dreams which had been deferred. Awake again, refreshed, she nourished herself sparingly, exercised, scribbled a cross in the air and murmured, “Into Your hands—” for unlike her husband, she believed the universe was more than an accident.
Next came the really tricky part. Of course Bob had wanted to handle it himself. Poor dear, he must be in absolute torment, knowing everything that could go wrong. She was luckier, Dorcas thought: too busy to be afraid. Shep’s flickering radar peeks had gotten fair-to-middling readings on an object that must be the kzin warship. Its
