The Traveller: John Katzenbach

There's a man travelling across America. He's handsome, persuasive and charming. He takes vitamin pills and award-winning photographs. And he takes lives...he kills the kind of girl who's easily convinced she's posing for a Playboy centrefold - until seconds before she dies. He travels with a woman he calls his Boswell, a literature student he has made his prisoner, whose task is to chronicle his deadly odyssey. On his trail are two people with their own special interest in the case the police department has abandoned. A woman cop, whose niece was one of the killer's victims, and a psychiatrist with a unique insight. He's an expert on sex offenders. And the killer is his brother.
