he was actually standing on a semi-smooth surface a few inches below it. "Damn!" he swore. He looked around. The concrete walls of the building were heavy and thick; he could not see clearly through them. He walked forward, hands outstretched, and saw his hands enter the wall. He walked through the wall, and felt a slight resistance, as though he were walking through water. He burst through the far side and the released pressure pitched him headlong. Once outside, Dave looked around. In the ghostly distance he could see the main laboratory building and the jeep bearing Jane, DeLieb, and Howes. They came to the building and Dave ran to meet them. "I'm here," he called. He screamed it. He yelled at the top of his voice. Jane walked through him. Her face was broken, tears filled her eyes, and Dave tried desperately to get her attention. But she walked through him and went on. They went in the door; Dave walked back through the phantom wall and met them inside. "Dave!" cried Jane. She ran across the room and reached—then recoiled, her face twisted in horror. "Like Claverly, like Phelps," she whispered. "Like hell!" yelled Dave. "Dammitall, I'm here!" "Gone!" said Jane. "I'm not gone!" snapped Dave. But a still voice inside him said that he was. He looked carefully at the place Jane watched with horror-filled eyes. He could see nothing. Then he went to Jane and peered into her eyes. The pupils were clear. Dave snorted. If he could not see the image of himself that Jane saw, there was no reason why he could see a possible reflection of that image in her pupils. "So he proved it," said DeLieb. "And so we continue, knowing that something or someone is maliciously attacking us," said Howes. "It's mine," said Jane in a flat voice. "No—" said DeLieb. "I want to follow him," she said. "Don't be a fool!" yelled Dave.
