Then Fetzer spoke up.

"How could we try this thing, Doc?"

It was the question Lucifer had been hoping for, and fearing. The problems ahead were piling up. He was a teacher, a scientist, not a leader. But he couldn't let his doubts show now.

"We can test it tomorrow night—if you can get word to all the people by that time."

"We can."

Once committed, the men plunged quickly into new plans. The guard tower on the hill behind the compound was picked for the first target. Almost everyone could see it from their own quarters. And it was large enough to provide a valid test for Lucifer's psi focus theory. The searchlight that always blazed on with the coming of dusk would be the signal.

"If it works," said Fetzer, "we've got to be ready to go all the way. They might not know what happened exactly, but you can be sure they'll move in and clamp down fast."

It was decided that a modified version of the original attack plan would be followed if the experiment succeeded. Only this time the diversionary forces would hit the Center and the small spaceport, while the main effort would be concentrated on getting the rest of the people into a clearing just outside the compound. From there they would try to function as a psi unit.

The wail of a forest animal drifted through the night.

"The boys are getting ready to short the field again," Fetzer explained. "We'd better get back."
