Billy's smile as he came out of the shrubbery was at least as peculiar as Mona Lisa's, for he was simultaneously on foot in Germany in 1944 and riding his Cadillac in 1967. Germany dropped away, and 1967 became bright and clear, free of interference from any other time. Billy was on his way to a Lions Club luncheon meeting. It was a hot August, but Billy's car was air-conditioned. He was stopped by a signal in the middle of Ilium's black ghetto. The people who lived here hated it so much that they had burned down a lot of it a month before. It was all they had, and they'd wrecked it. The neighborhood reminded Billy of some of the towns he had seen in the war. The curbs and sidewalks were crushed in many places, showing where the National Guard tanks and half-tracks had been.
