"What have we got to lose?"
Swanson shrugged. "It's dangerous," he said again. But he went along.
Burckhardt's idea was very simple. He was sure of only one thing—the tunnel went somewhere. Martians or Russians, fantastic plot or crazy hallucination, whatever was wrong with Tylerton had an explanation, and the place to look for it was at the end of the tunnel.
They jogged along. It was more than a mile before they began to see an end. They were in luck—at least no one came through the tunnel to spot them. But Swanson had said that it was only at certain hours that the tunnel seemed to be in use.
Always the fifteenth of June. Why? Burckhardt asked himself. Never mind the how. Why?
And falling asleep, completely involuntarily—everyone at the same time, it seemed. And not remembering, never remembering anything—Swanson had said how eagerly he saw Burckhardt again, the morning after Burckhardt had incautiously waited five minutes too many before retreating into the darkroom. When Swanson had come to, Burckhardt was gone. Swanson had seen him in the street that afternoon, but Burckhardt had remembered nothing.
And Swanson had lived his mouse's existence for weeks, hiding in the woodwork at night, stealing out by day to search for Burckhardt in pitiful hope, scurrying around the fringe of life, trying to keep from the deadly eyes of them.
Them. One of "them" was the girl named April Horn. It was by seeing her walk carelessly into a telephone booth and never come out that Swanson had found the tunnel. Another was the man at the cigar stand in Burckhardt's office building. There were more, at least a dozen that Swanson knew of or suspected.
They were easy enough to spot, once you knew where to look—for they, alone in Tylerton, changed their roles from day to day. Burckhardt was on that 8:51 bus, every morning of every day-that-was-June-15th, never different by a hair or a moment. But April Horn was sometimes gaudy in the cellophane skirt, giving away candy or cigarettes; sometimes plainly dressed; sometimes not seen by Swanson at all.
Russians? Martians? Whatever they were, what could they be hoping to gain from this mad masquerade?
