Dark started running. He dropped the marsuits, and ran down the corridor. He leaped up the stairs, two and three at a time. Breathless, his heart pounding, he staggered down the upper corridor and impatiently went through the seemingly interminable process of negotiating the airlock. He emerged into the big room. It was empty. The ceiling was open to the Martian sky. The sunlight poured into the roofless room. In the sky, a small, teetering object rose and moved away from Ultra Vires, its blades whirring a sparkling circle in the thin air. Dark reached out to it with his mind, and again he was in the copter. Nuwell sat tensely at the controls, guiding it. Maya was in the other seat, her arms bound down by her sides, her expression agonized. Nuwell was unaware of Dark's mental presence. Maya sensed it and her mind turned toward him. _Dark, Dark, what can we do? I should have been watching for him. I should have known, after he saw us together, that he would do something._ Dark: _It was my fault, Maya. I shouldn't have left you alone. I just didn't consider him a factor to be reckoned with, and I should have known better._ Maya: _What can we do?_ Nuwell turned to Maya, and his face was bitter and sullen. His brown eyes were flat with anger. "You treacherous witch, I should have known better than to trust you after that trick of trying to help Kensington escape. I wanted to give you a chance, because I thought that, with him dead, you might have recovered from your madness," he said. A change came over his face: a mixture of fear, disbelief and utter lack of comprehension. "He _was_ dead," said Nuwell, a hysterical note underlying his tone. "I saw him. You saw him dead, too, didn't you, Maya? How could he be back there with you?" Maya's only answer was a defiant smile. "There's some explanation for this," said Nuwell, more positively. "I don't know what it is, but I'll find it. That man back there isn't Dark Kensington, because Kensington's dead. Maya, I promise you, I'm going to find out what the answer is, but first I'm going to make sure that you don't cause me any more trouble." Dark touched Maya's mind. _Maya, I'm going to try something here._ He moved back. He was outside the copter, near it, keeping pace with it as it flew. It was tilted slightly forward, falling forward through the sky at the pull of its blades. Dark seized the copter with his mind. He tried to drag it back. It hesitated. It quivered. Then it jerked forward and went on. He felt his mental grasp slipping from it. Suddenly he was completely in the big room in Ultra Vires, the room with its roof open to the sky. He could no longer touch the copter. He could no longer be in it. He could no longer touch Maya's mind. He tried. He reached out again. But he failed. He was where he was.
