shadows covered the face of the land. The crouching shadows of enormous insects. He could not escape from them because they were everywhere; when he broke into a run the mantis shapes followed him. They towered above him, sinister, horrible. He felt like a man caught in an invisible trap, the sky hemming him in, the ground beneath his feet a dissolving quagmire. He shook the illusion off, for he did not want Joan to see the shadows as he saw them. What was it Crendon had said? She must be made to feel that you need her. Well, he did; he knew now that more than his own honor was at stake. If the alien ship could not be located his fears would not remain subjective. The fate of humanity hung in the balance. His imagination had been stimulated abnormally by the events of the past few days; now it was leaping ahead of developments. For all he knew to the contrary the alien ship had foundered in the void or crashed on one of the inner planets in a red swirl of destruction.

Joan paused, as though she didn't quite know how to make the complexity of the problem clear to her husband. "I can't explain the power," she said; "I know so little about 'time', far less than the physicists think
