Trevor Gray is a loner. One day his solitude in Chattaoga is interrupted when he sees a man who looks exactly like him-his doppelganger. Trevor follows this man, Brad Compton, observing him and his beautiful wife from a distance, never revealing his identity. A short time later, Brad goes missing and is assumed dead. When the police learn about Trevor, he becomes a prime suspect in Brad's disappearance-but so is a mysterious homeless man who later becomes Trevor's friend. As the investigation progresses, strange forces seem to bring people together in ways that change their lives forever; those involved find out how little control they have over their own fates. This is a tale of mystery and betrayal; of love and friendship; and of the enduring quest for understanding in a world that seems to have meaning.
