Suppose the case stopped working now? Oh, this couldn’t go on. A decision hanging fire for a week finally crystallized into a conclusion so obvious he felt like kicking himself. Perfectly obvious! Why hadn’t he thought of it at the very beginning? He concentrated on the problem: How can I get rid of Tharn? He pushed the button.... And, a moment later, he knew the answer. It would be simple, really. The pressing urgency was gone suddenly. That seemed to release a fresh flow of thought. Everything became quite clear. He waited for Tharn. He did not have to wait long. There was a tremor in the shimmering air, and the turbaned, pallid figure sprang into tangible reality. The rod-weapon was poised. Taking no chances, Kelvin posed his problem again, pressed the button, and instantly reassured himself as to the method. He simply thought in a very special and peculiar way—the way Quarra Vee had indicated. Tharn was flung back a few feet. The moustached mouth gaped open as he uttered a cry. “Don’t!” the android cried. “I’ve been trying to—” Kelvin focused harder on his thought. Mental energy, he felt, was pouring out toward the android. Tharn croaked, “Trying—you didn’t—give me—chance—” And then Tharn was lying motionless on the hot sand, staring blindly up. The seven-fingered hands twitched once and were still. The artificial life that had animated the android was gone. It would not return. Kelvin turned his back and drew a long, shuddering breath. He was safe. He closed his mind to all thoughts but one, all problems but one. How can I find the red-moustached man? He pressed the button. This is the way the story starts: Quarra Vee sat in the temporal warp with his android Tharn, and made sure everything was under control.
