McCauley went on. This was outside the cargo-netted space and near where the rockets went up. Fallon clung fast to the drill rod. The others went about their business. Stars blazed in the daylight sky. The sun flamed far, far away. Fallon stayed motionless, gripping the rod that was securely set into the metal of Eros. Presently he stirred stealthily and tugged at the rope with the new knot in the end. It was firm. He tugged more strongly. It held. Then, with the gentlest and most fearful of tuggings, he drew himself to where McCauley had fastened his space rope. He examined McCauley's knot. Fallon was afraid of McCauley, because he had made a bargain he did not believe McCauley would keep. He believed that McCauley meant to be the sole survivor of the Mars Expedition, returning secretly to Earth with tens of millions in stolen atomic fuel. And Fallon believed that McCauley had planned the near-tragedies of Hathaway and Soames. Therefore he believed that McCauley would be arranging more successful accidents for those two and the rest, and that because Fallon knew of McCauley's plans, he, Fallon, would be the first to be destroyed. He could see nothing the matter with the knot, but he distrusted it with a despairing terror. He untied it so he could retie it himself. And McCauley's voice roared in the headphones in his helmet: "Fallon! What are you doing?" Fallon started violently. He jumped. His space rope was not anchored, and Eros has no measurable gravity. Fallon went up and away from the asteroid, toward a thousand million light-years of emptiness. His space rope rose with him, not trailing behind but writhing and twisting weightlessly, more like a tendril of smoke than anything else. Horror filled him. He could not cry out. "Get him!" roared McCauley. Space-suited figures turned in the stark white sunlight, and inky black shadows followed their movements in strict synchrony. Fallon was twenty feet high.... Forty. A space-suited figure jerked at his space rope for assurance and then leaped up toward Fallon. It was a miss. The glittering metallic space suit swung in a wide arc and then down to ground again. A second man leaped. A third. They swept past the line of his flight. The space rope of one of the men touched Fallon's. Had it struck near the middle, it might have brought his rope down captive. But the end of Fallon's rope flicked free and he went on toward the stars. Now there were babblings. Space-armored figures moved swiftly toward a single spot, pulling themselves by their ropes.... Fallon was sixty feet high.... Seventy. Then a man came soaring straight upward. He missed Fallon, but he flailed a rope and it tangled in Fallon's. The bobbing, rope-held figure hauled in, and had Fallon's rope fast. He wrapped it swiftly about his arm. When the jerk came it was not severe. Then a single figure on the asteroid pulled down and down and down, and Fallon was towed to solidity. He touched before he could utter a sound.
