"Then do it. I'm canceling the flight that's leaving now and I'll keep the ship here, ready to go. When the machine is built I want you to track the signal and report back to me."

"Agreed," Jason said, standing up. "As soon as I have this hole in my back looked at I'll draw up a list of things needed."

A grim, unsmiling man named Skop was assigned to Jason as a combination guide and guard. He took his job very seriously, and it didn't take Jason long to realize that he was a prisoner-at-large. Kerk had accepted his story, but that was no guarantee that he believed it. At a single word from him, the guard could turn executioner.

The chill thought hit Jason that undoubtedly this was what would happen. Whether Kerk accepted the story or not—he couldn't afford to take a chance. As long as there was the slightest possibility Jason had contacted the grubbers, he could not be allowed to leave the planet alive. The woods people were being simple if they thought a plan this obvious might succeed. Or had they just gambled on the very long chance it might work? They certainly had nothing to lose by it.

Only half of Jason's mind was occupied with the work as he drew up a list of materials he would need for the psionic direction finder. His thoughts plodded in tight circles, searching for a way out that didn't exist. He was too deeply involved now to just leave. Kerk would see to that. Unless he could find a way to end the war and settle the grubber question he was marooned on Pyrrus for life. A very short life.

When the list was ready he called Supply. With a few substitutions, everything he might possibly need was in stock, and would be sent over. Skop sank into an apparent doze in his chair and Jason, his head propped against the pull of gravity by one arm, began a working sketch of his machine.

Jason looked up suddenly, aware of the silence. He could hear machinery in the building and voices in the hall outside. What kind of silence then—?

Mental silence. He had been so preoccupied since his return to the city that he hadn't noticed the complete lack of any kind of psi sensation. The constant wash of animal reactions was missing, as was the vague tactile awareness of his PK. With sudden realization he remembered that it was always this way inside the city.

He tried to listen with his mind—and stopped almost before he began. There was a constant press of thought about him that he was made aware of when he reached out. It was like being in a vessel far beneath the ocean, with your hand on the door that held back the frightening pressure. Touching the door, without opening it, you could feel the stresses, the power pushing in and waiting to crush you. It was this way with the psi pressure on the city. The unvoiced hate-filled screams of Pyrrus would instantly destroy any mind that received them. Some function of his brain acted as a psi-circuit breaker, shutting off awareness before his mind could be blasted. There was just enough leak-through to keep him aware of the pressure—and supply the raw materials for his constant nightmares.

There was only one fringe benefit. The lack of thought pressure made it easier for him to concentrate. In spite of his fatigue the diagram developed swiftly.
