One minute before that, he had opened the door of his room to check the morning temperature. He had left it open, and the closet just inside the entrance passageway was faced with mirrored glass, and there was a shaving mirror in the bathroom on a cantilevered arm, and by a freak of optical chance he caught sight of four men getting out of a car and walking toward the motel office. Pure luck, but a guy as vigilant as Jack Reacher gets lucky more times than the average.
