Each coffin had a window mounted on its top side. What effort to honor the remains of single members! Steel hopped onto one and looked down. The corpse was perfectly preserved; in fact, the blue light made everything look frozen. He cocked a second head over the edge of the box, got a double view on the creature within. It was far smaller than the two they had killed under the ship. It was even smaller than the one they had captured. Some of Steel's advisors thought the small ones were pups, perhaps unweaned. It made sense; their prisoner never made thought sounds.

Partly as an act of discipline, he stared for a long while at the alien's queer, flat face. The echo of his mind was a continuing pain, eating at his attention, demanding that he leave. Let the pain continue. He had withstood worse before, and the packs outside must know that Steel was stronger than any of them. He could master the pain and have the greater insight… And then he would work their butts off, quilting these rooms and studying the contents.

So Steel stared, almost thoughtless, into the face. The screaming in the walls seemed to fade a little. The face was so ugly. How could the creature eat? He had looked at the charred corpses outside, noticed their small jaws and randomly misshapen teeth.

A few minutes passed; the noise and ugliness mixed together, dream-like… And out of his trance, Steel new a nightmare horror: The face moved. The change was small, and it happened very, very slowly. But over a period of minutes, the face had changed.

Steel's fell from the coffin; the walls screamed back terror. For a few seconds, he thought the noise would kill him. Then he regained himself with quiet thought. He crawled back onto the box. All his eyes stared through the crystal, waiting like a pack on hunt… The change was regular. The alien in the box was breathing, but fifty times more slowly than any normal member. He moved to another box, watched the creature in it. Somehow, they were all alive. Inside those boxes, their lives were simply slowed.

He looked up from the boxes, almost in a daze. That the room reeked of evil was an illusion of sound… and also the absolute truth.

The mantis alien had landed far from the tropics, away from the collectives; perhaps it thought the Arctic Northwest a backward wilderness. It had come in a ship jammed with hundreds of mantis pups. These boxes were like larval casings: the pack would land, raise the small ones to adulthood — out of sight of civilization. Steel felt his pelts puff up as he thought about it. If the mantis pack had not been surprised, if Steel's troops had been any less aggressive… it would have been the end of the world.

Steel staggered to the outer hatch, his fears coming louder and louder off the walls. Even so, he paused a moment in the shadows and the screams. When his members trooped down the stairs, he moved calmly, every jacket neatly in place. Soon enough his advisors would know the danger, but they would never see fear in him. He walked lightly across the steaming turf, out from under the hull. But even he could not resist a quick look across the sky. This was one ship, one pack of aliens. It had had the misfortune of running into the Movement. Even so, its defeat had been partly luck. How many other ships would land, had already landed? Was there time for him to learn from this victory?

Steel's mind returned to the present, to his eyrie lookout above the castle. That first encounter with the ship was many tendays past. There was still a threat, but now he understood it better, and — as was true of all great threats — it held great promise.

On the rampart, Flenser-in-Waiting slid through the deepening twilight. Steel's eyes followed the pack as it walked beneath the torches, and one by one disappeared down stairs. There was an awful lot of the Master in that fragment; it had understood many things about the alien landing before anyone else.

Steel took one last look across the darkening hills as he turned and started down the spiral stair. It was a long, cramped climb; the lookout sat atop a forty-foot tower. The stair was barely fifteen inches wide, the ceiling less that thirty inches above the steps. Cold stone pressed in from all around, so close that there were no echoes to confuse thought — yet also so close that the mind was squeezed into a long thread. Climbing the spiral required a twisting, strung-out posture that left any attacker easy prey for a defender in the eyrie. Such was military architecture. For Steel, crawling the cramped dark was pleasant exercise.

The stairs opened onto a public hallway, ten feet across with back-off nooks every fifty feet. Shreck and a bodyguard were waiting for him.

"I have the latest from Woodcarvers," said Shreck. He was holding sheets of silkpaper.

Losing the other alien to Woodcarvers had once seemed a major blow. Only gradually had he realized how well it could work out. He had Woodcarvers infiltrated. At first he'd intended to have the other alien killed; it would have been easy to do. But the information that trickled north was interesting. There were some bright people at Woodcarvers. They were coming up with insights that had slipped past Steel and the Master -the fragment of the Master. So. In effect, Woodcarvers had become Steel's second alien laboratory, and the Movement's enemies were serving him like any other tool. The irony was irresistible.

"Very good, Shreck. Take it to my den. I'll be there shortly." Steel waved the whitejackets into a back-up nook and swept past him. Reading the report over brandy would be a pleasant reward for the day's work. In the meantime, there were other duties and other pleasures.

The Master had begun building Hidden Island Castle more than a century earlier; it was growing yet. In the oldest foundations, where an ordinary ruler might put dungeons, were the Flenser's first laboratories. Many could be mistaken for dungeons — and were by their inhabitants.

Steel reviewed all the labs at least once a tenday. Now he swept through the lowest levels. Crickers fled before the light of his guard's torches. There was a smell of rotting meat. Steel's paws skidded where slickness lay upon the stone. Holes were dug in the floor at regular intervals. Each could hold a single member, its legs jammed tight to its body. Each was covered by a lid with tiny air holes. It took the average member about three days to go mad in such isolation. The resulting "raw material" could be used to build blank packs. Generally, they weren't much more than vegetables, but then that was all the Movement asked of some. And sometimes remarkable things came from these pits: Shreck for instance. Shreck the Colorless, some called him. Shreck the stolid. A pack who was beyond pain, beyond desire. Shreck's was the loyalty of clockwork, but built from flesh and blood. He was no genius, but Steel would have given an eastern province for five more of him. And the promise of more such successes made Steel use the isolation pits again and again. He had recycled most of the wrecks from the ambush that way…

Steel climbed back to higher levels, where the really interesting experiments were undertaken. The world regarded Hidden Island with fascinated horror. They had heard of the lower levels. But most didn't realize what a small part those dark spaces played in the Movement's science. To properly dissect a soul, you need more than benches with blood gutters. The results from the lower levels were simply the first steps in Flenser's intellectual quest. There were great questions in the world, things that had bothered packs for thousands of years. How do we think? Why do we believe? Why is one pack a genius and another an oaf? Before Flenser, philosophers argued them endlessly and never got closer to the truth. Even Woodcarver had pranced around the issues, unwilling to give up her traditional ethics. Flenser was prepared to get the answers. In these labs, nature itself was under interrogation.
