Man-Kzin Wars III by Larry Niven (good short books TXT) 📕

Nervously, he extended his pointed tongue and groomed his tendrils. Something was very strange here. He blinked his eyelid shut and thought for a moment, then spoke:

“Give me a reading on the mass sensor.”

That worked from inductor coils within the single molecule of the hull; very little besides antimatter could penetrate a shipmetal hull, but gravity could. The figures scrolled up, and Dnivtopun blinked his eye at them in bafflement.

“Again.” They repeated themselves, and the thrint felt a deep lurch below his keelbones. This felt wrong.

“Something is wrong,” Herrenmann Ulf Reichstein-Markham muttered to himself, in the hybrid German-Danish-Balt-Dutch tongue spoken by the ruling class of Wunderland. It was Admiral Reichstein-Markham now, as far as that went in the rather irregular command structure of the Free Wunderland Space Navy, the space-based guerillas who had fought the kzinti for a generation.

“Something is very wrong.”

That feeling had been growing since the four ships under his command had matched vectors with this anomalous asteroid. He clasped his hands behind his back, rising slightly on the balls of his feet, listening to the disciplined murmur of voices among the crew of the Nietzsche. The jury-rigged bridge of the converted ore-carrier was more crowded than ever, after the success of his recent raids. Markham’s eyes went to the screen that showed the other units of his little fleet. More merchantmen, with singleship auxiliaries serving as fighters. Rather thoroughly armed now, and all equipped with kzinti gravity-polarizer drives. And the cause of it all, the Catskinner. Not very impressive to look at, but the only purpose-built warship in his command. A UN Dart-class attack boat, a spindle shape, massive fusion-power unit, tiny life-support bubble, asymmetric fringe of weapons and sensors.

It had been a United Nations Space Navy ship, piggy-backed into the Alpha Centauri system on the ramscoop battlecraft Yamamoto, only two months ago, dropped off with agents aboard. And the UN personnel had been persuaded to . . . entrust the Catskinner to him while they went on to their mission on Wunderland. The Yamamoto’s raid had sown chaos among the kzinti; the near-miraculous assassination of the alien governor of Wunderland had done more. Markham’s fleet had grown accordingly, but it was still risky to group so many together. Or so the damnably officious sentient computer had told him.

His scowl deepened. Consciousness-level computers were a dead-end technology, doomed to catatonic madness in six months or less from activation, or so the books all said. Perhaps this one was too, but it was distressingly arrogant in the meantime.

The feeling of wrongness grew, like wires pulling at the back of his skull. He felt an impulse to blink his eye (eye?) and knot his tendrils (tendrils?), and for an instant his body felt an itch along the bones, as if his muscles were trying to move in ways outside their design parameters.

Nonsense, he told himself, shrugging his shoulders in the tight-fitting grey coverall of the Free Wunderland armed forces. Markham flicked his eyes sideways at the other crewfolk; they looked uncomfortable too, and . . . what was his name? Patrick O’Connell, yes, the redhead . . . looked positively green. Stress, he decided.

“Catskinner,” he said aloud. “Have you analyzed the discrepancy?” The computer had no name apart from the ship into which it had been built; he had asked, and it had suggested “Hey, you.”

“There is a gravitational anomaly, Admiral Herrenmann Ulf Reichstein-Markham,” the machine on the other craft replied. It insisted on English and spoke with a Belter accent, flat and rather neutral, the intonation of a people who were too solitary and too crowded to afford much emotion. And a slight nasal overtone, Sol-Belter, not Serpent Swarm.

The Wunderlander’s face stayed in its usual bony mask; the Will was master. Inwardly he gritted teeth, ashamed of letting a machine’s mockery move him. If it even knows what it does, he raged. Some rootless cosmopolite Earther deracinated degenerate programmed that into it.

“Here is the outline; approximately 100 to 220 meters below the surface.” A smooth regular spindle-shape tapering to both ends.

“Zat—” Markham’s voice showed the heavy accent of his mother’s people for a second; she had been a refugee from the noble families of Wunderland, dispossessed by the conquest. “That’s an artifact!”

“Correct to within 99.87% probability, given the admittedly inadequate information,” the computer said. “Not a human artifact, however.”

“Nor kzinti.”

“No. The design architecture is wrong.”

Markham nodded, feeling the pulse beating in his throat. His mouth was dry, as if papered in surgical tissue, and he licked the rough chapped surface of his lips. Natural law constrained design, but within it tools somehow reflected the . . . personalities of the designers. Kzinti ships tended to wedge and spike shapes, a combination of sinuosity and blunt masses. Human vessels were globes and volumes joined by scaffolding. This was neither.

“Assuming it is a spaceship,” he said. Glory burst in his mind, sweeter than maivin or sex. There were other intelligent species, and not all of them would be slaves of the kzinti. And there had been races before either . . .

“This seems logical. The structure . . . the structure is remarkable. It emits no radiation of any type and reflects none, within the spectra of my sensors.”

Perfect stealthing! Markham thought.

“When we attempted a sampling with the drilling laser, it became perfectly reflective. To a high probability, the structure must somehow be a single molecule of very high strength. Considerably beyond human or kzinti capacities at present, although theoretically possible. The density of the overall mass implies either a control of gravitational forces beyond ours, or use of degenerate matter within the hull.”

The Wunderlander felt the hush at his back, broken only by a slight mooing sound that he abruptly stopped as he realized it was coming from his own throat. The sound of pure desire. Invulnerable armor! Invincible weapons, technological surprise!

“How are you arriving at its outline?”

“Gravitational sensors.” A pause; the ghost in Catskinner’s machine imitated human speech patterns well. “The shell of asteroidal material seems to have accreted naturally.”

“Hmmm.” A derelict, then. Impossible to say what might lie within. “How long would
