of the gravity-rotor over his head, shifted a bit so that he gazed squarely at Jim Palmer. He laughed then, feeling the tight control-band gone from his mind, sensing the advantage that had come back to him. He twisted a bit, still not understanding all that had happened, and his mouth opened in surprise at what he saw. There were two of them, two grub-like slugs resting quiescently on the metal floor, each of them the exact duplicate of the thing he had shot upon landing on Venus. All of the maelstrom disappeared then from his mind, and his thinking grew crystal clear. He saw Jim Palmer bending toward him, and then the ati-guns were in his hands, and their wailing crescendos of unleashed power filled the Comet with screaming echoes. For an interminable instant, the slugs seemed to absorb the ati-rays, then they collapsed into puddles of obscene flesh that disappeared into charred flakes of ash. Don Denton lay where he was, the guns silent in his hands, seeing the intelligence that flashed into Jim Palmer's eyes. "Oh, my God!" Jim Palmer said stupidly, stared at the strap he still held in his heavy hand. Don Denton rolled from beneath the gravity-rotor, came to his feet, dodged around the dazed man, tugged open the nearest panel in the wall. He took two small, belt gravity-rotors from a shelf, handed one to Palmer, buckled the other about his head. "Put that rotor about your head, Palmer," he ordered. "We've got some work to do."

And then Jean was in Don Denton's arms, her slender shoulders shaking in a torrent of sobs, and he was soothing her with a clumsy gentleness that
