Gray's practised eye gauged the stranger's speed against his own, and he cursed softly. Abruptly he wheeled the ship and started down again, cutting his rockets as the shadow swallowed them. The ship was eerily silent, dropping with a rising scream as the atmosphere touched the hull. "What are you going to do?" asked Jill almost too quietly. He didn't answer. Maneuvering the ship on velocity between those stupendous pinnacles took all his attention. Caron, at least, couldn't follow him in the dark without exhaust flares as guides. They swept across the wind-torn plain, into the mouth of the valley where Gray had worked, braking hard to a stop under the cables. "You might have got past them," said Jill. "One chance in a hundred." Her mouth twisted. "Afraid to take it?" He smiled harshly. "I haven't yet reached the stage where I kill women. You'll be safe here--the men will find you in the morning. I'm going back, alone." "Safe!" she said bitterly. "For what? No matter what happens, the Project is ruined." "Don't worry," he told her brutally. "You'll find some other way to make a living." Her eyes blazed. "You think that's all its means to us? Just money and power?" She whispered, "I hope they kill you, Duke Gray!" * * * * * He rose lazily and opened the air lock, then turned and freed her. And, sharply, the valley was bathed in a burst of light. "Damn!" Gray picked up the sound of air motors overhead. "They must have had infra-red search beams. Well, that does it. We'll have to run for it, since this bus isn't armed." With eerie irrelevancy, the teleradio buzzed. At this time of night, after the evening storms, some communication was possible. Gray had a hunch. He opened the switch, and the face of John Moulton appeared on the screen. It was white and oddly still. "Our guards saw your ship cross the plain," said Moulton quietly. "The men of the Project, led by Dio, are coming for you. I sent them, because I have decided that the life of my daughter is less important than the lives of many thousands of people. "I appeal to you, Gray, to let her go. Her life won't save you. And it's very precious to me." Caron's ship swept over, low above the cables, and the grinding concussion of a bomb lifted the ship, hurled it down with the stern end twisted to uselessness. The screen went dead. Gray caught the half stunned girl. "I wish to heaven I could get rid of you!" he grated. "And I don't know why I don't!" But she was with him when he set out down the valley, making for the cliff caves, up where the copper cables were anchored. Caron's ship, a fast, small fighter, wheeled between the cliffs and turned back. Gray dropped flat, holding the girl down. Bombs pelted them with dirt and uprooted vegetables, started fires in the wheat. The pilot found a big enough break in the cables and came in for a landing.
