On the ledge, Johnny Retch wiped sweat from his face. From his pockets, he methodically refilled the almost empty clip of the gun. He looked down at Gotch, who was sitting up.
"You killed the Jezbro!" Gotch was whispering. His eyes were searching the sky as if he still did not believe what he had seen happen.
"Sure," Retch answered. "I don't know what the hell it was, but it could be killed. Anything can be killed, Gotch. Remember that." The sting of acid crept into his voice. "Get up. We're going on up the ledge."
"By God, Johnny, you can do anything!" Gotch spoke. He rose with suddenly renewed confidence. "Wait'll we get to them—" He looked up the ledge toward the mouth of the tunnel.
Effra was seated in the operator's chair in front of the complex control panel that resembled the key board of a strange organ. She had been watching an image move in the screen directly in front of her eyes.
This image—it had been that of a great bird—had suddenly vanished.
"The Jezbro was destroyed!" she whispered. "The core of it was struck. When that happens, the complete projection is torn to pieces!" Her face was white with strain.
Parker took his eyes off the screen where he had been watching something that he did not pretend to understand.
"Sometimes they are very difficult to control," Effra continued, her voice a whisper. "Once set in motion, they seem almost to achieve life of their own. I did not send the Jezbro against the men on the ground, I sent it against the man on the ledge, against this Retch. But—" her voice faltered.
