On the evening before Thanksgiving, Hal Chase, a guard in the San Francisco County Jail, drives to the airport to pick up his step-brother for the weekend. When they return, Hal's wife, Katie, has disappeared without a clue. By the time Dismas Hardy hears about this, Katie has been missing for five days. The case strikes close to home because Katie had been seeing Hardy's wife, a marriage counselor. The original missing persons case becomes a suspected homicide, and Hal is the prime suspect.
