The kzin screamed and leaped.

In any true gravity field, Robert Saxtorph would have been dead half a minute later. The body has its wisdom, and his had been schooled through hard years. Before he really knew what a thunderbolt was coming at him, he had sprung aside—against the asteroid spin. As his weight dropped, he thrust a foot once more to drive himself off the deck, strike a wallfront, recover control over his mass, and bounce to a crouch.

The kzin was clearly not trained for such tricks. He had pounced straight out of a crosslane, parallel to Tiamat’s rotation axis. Coriolis force was too slight to matter. But instead of his prey, he hit the opposite side of Ranzau Passage. Pastel plastic cracked under the impact; the metal behind it boomed. He recovered with the swiftness of his kind, whirled about, and snarled.

For an instant, neither being moved. Ten meters from him, the kzin stood knife-sharp in Saxtorph’s awareness. It was as if he could count every red orange hair of the pelt. Round yellow eyes glared at him out of the catlike face, above the mouthful of fangs. Bat-wing ears were folded out of sight into the fur, for combat. The naked tail was angled past a columnar thigh, stiffly held. The claws were out, jet-black, on all four digits of either hand. Except for a phone on his left wrist, the kzin was unclad. That seemed to make even greater his 250 centimeters of height, his barrel thickness.

Before and behind the two, Ranzau Passage curved away. Windows in the wallfronts were empty, doors closed, signs turned off; workers had gone home for the nightwatch. They were always few, anyway. This industrial district had been devoted largely to the production of spaceship equipment which the hyperdrive was making as obsolete as fission power. There was no time to be afraid. “Hey, wait a minute, friend,” Saxtorph heard himself exclaim automatically, “I never saw you before, never did you any harm, didn’t even jostle you—”

Of course that was useless, whether or not the kzin knew English. Saxtorph hadn’t adopted the stance which indicated peacefulness. It would have put him off balance. The kzin bounded at him.

Saxtorph released the tension in his right knee and swayed aside. Coming upspin, his speed suddenly lessening his weight, the kzin—definitely not a veteran of space—went by too fast to change direction at once. As he passed, almost brushing the man, the gingery smell of his excitement filling the air, Saxtorph thrust fingers at an eye. That was just about the only vulnerable point when a human was unarmed. The kzin yowled; echoes rang.

Saxtorph was shouting too, “Help, murder, help!”

Somebody should be in earshot of that. The kzin skidded to a halt and whipped about. It would have been astounding how quick and agile his bulk was, if Saxtorph hadn’t seen action on the ground during the war.

Again saving his breath, the man backed downspin, but slantwise, so that he added little to his weight. Charging full-out, the kzin handicapped himself much more. The extra drag on his mass meant nothing to his muscles, but confused his reflexes. Dodging about, Saxtorph concentrated first on avoiding the sweeps of those claws, second on keeping the velocity parameters unpredictably variable. From time to time he yelled. One slash connected. It ripped his tunic from collar to belt, and the undershirt beneath. Blood welled along shallow gashes. As he jumped clear, Saxtorph cracked the blade of his hand onto the flat nose before him. It did no real harm, but hurt. The kzin’s eyes widened. The pupil of the undamaged one grew narrower yet. He had seen the scars across his opponent’s chest. This human had encountered at least one kzin before, face to face.

But Saxtorph was 15 years younger then, and equipped with a Gurkha knife. Now the wind was gusting out of him. His gullet was afire. Sluggishness crept into his motions. “Ya-a-ah, police, help! Ki-yai!”

A whistle skirled. The kzin halted. He stared past Saxtorph. The man dared not turn his head, but he heard cries and footfalls. The kzin turned and sped in the opposite direction, upspin. He whirled into the first crosslane he came to and disappeared.

And that wasn’t like his breed, either. Saxtorph sagged back against a wallfront and sobbed breath into his lungs. Sweat was cold and acrid on him. He felt the beginnings of the shakes and started calling calm down on himself, as the Zen master who helped train him for war had taught.

One cop waved off a score or so of people whom the commotion had drawn after him and his companion. The other approached Saxtorph. He was stocky, clean-shaven, unremarkable except for the way he cocked his ears forward—neither aristocrat nor Belter, just a commoner from Wunderland. “Was ist hier los?” he demanded somewhat wildly.

Saxtorph could have recalled the Danish of his childhood, before the family moved to America, and brushed the rust off what German he’d once studied, and made a stab at this language. The hell with it. “Y-y-you speak English?” he panted.

“Ja, some,” the policeman answered. “Vat is t’is? Don’t you know not to push a kzin around?”

“I sure do know, and did nothing of the sort.” Steadiness was returning. “He bushwhacked me, completely unprovoked. And, yes, this sort of thing isn’t supposed to happen with kzinti, and I can’t make any more sense of it than you. Aren’t you going to chase him?”

“He’s gone,” said the policeman glumly. “He vill be back in Tigertown and t’e trail lost before ve can bring a sniffer to follow him. How you going tell vun of t’ose Teufel from anot’er? You come along to t’e station, sir. Ve vill give you first aid and take your statement.”

Saxtorph drew a long breath, grinned lopsidedly, and replied, “Okay. I’ll want to make a couple of phone calls. My wife, and—it’d be smart to ask Commissioner Markham if I can put off my appointment with him.”

Tiamat is much less known outside its system than it deserves to be. Once hyperdrive transport has become readily available and cheap, it may well be receiving tourists from all of human space: for it is a curious object, with considerable historical significance as well.

Circling Alpha Centauri A near the middle of those asteroids called the Serpent Swarm, it was originally a chondritic body with a sideritic component giving it more structural strength than is usual for that kind. A rough cylinder, about 50 kilometers in length and 20 in diameter, it rotated on its long axis in a bit over ten hours; and at the epoch when humans arrived, that axis happened to be almost normal to the orbital plane. Those who settled on Wunderland paid it no attention; they had a habitable planet. The Belters who came later, from the asteroids of the Solar System, realized what a treasure was theirs. Little work was needed to make the cylinder smooth, control precession, and give it a centrifugal acceleration of one g at the circumference. With its axial orientation, the velocity changes for spacecraft to dock were minimal, and magnetic anchors easily held them fast until they were ready to depart. The excavation of rooms and passages in the yielding material went rapidly. Thereafter, spaces just under the surface provided Earth-weight for such activities as required it, including the bringing of babies to term; farther inward were the levels of successively lower weight, where Belters felt comfortable and where other undertakings were possible.

Everywhere around orbited members of the Swarm, their mineral wealth held in negligible gravity wells. Tiamat boomed. It became an industrial center, devoted especially to the production of things associated with spacefaring.

When the kzinti invaded, they were quick to realize its importance. Their introduction of the gravity polarizer changed many of the manufacturing programs, but scarcely affected Tiamat itself; one seldom had any reason to adjust the field in a given section, since one could have whatever weight was desired simply by going to the appropriate level. Out of the years that followed have come countless stories of heroism, cowardice, resistance, collaboration, sabotage, salvage, ingenuity, intrigue, atrocity, mercy. Some are true. Certainly, when the human hyperdrive armada entered the Centaurian System, Tiamat might well have been destroyed, had not the Belter freedom fighters taken it over from within.
