and twisted the bar. In almost the same instant she snatched the gun from Lansfer's holster. She backed away a step and leveled it at the officer. "Turn this ship around," she ordered. "We're going back to Mars." Lansfer's narrowed eyes peered at the control board where she had disconnected the grapples. He turned to the girl. His voice was flat, sullen. "Give me that gun." "No." She backed away another step and he followed, hand reaching. Her face became paler. Lansfer stopped and stared into her eyes. His eyes were compelling, hypnotic. She stood motionless and tried to shake the effect. Lansfer moved a step closer. Remish's hand gently removed the gun from her fingers. Barnard swore disgustedly. Why had Gail cut the grapples? She must have some fool idea that he could beat the police to Pluto, win out on his own. Maybe he could. There were only two little difficulties involved. First, he didn't know where Pluto was, or how to find it. Second—the planet was Earth-size, and where on its millions of square miles of surface was whatever he wanted? The second problem was partly solved. From Lansfer's mind he had a vague picture of a vast white sea, trapped in a ring of white mountains that knifed into a black sky. From Lansfer's mind—! Even in his neoin jag, a jolt came to him. How did Lansfer know that? Frantically, his thoughts speared back to the police ship. But it was too far now—only confused fragments came. But one image brought him to his feet, sobered and fearful for Gail's safety. Wildly he searched space for the magenta blasts of the police ship's rockets. Because his extra-sensory perception brought one clear image. In Lansfer's pocket he had perceived the ancient twentieth century coin he had given to George Melvin.

At the junction of the hairs was nothing. But he found a grayish blob larger than the others at the edge of the plate. Experimentally, he turned in the rockets and headed for it. It moved steadily to the right, so
