A Pulitzer Prize-winning journalist gets inside the mind of a serial killer—and uncovers what makes truly evil men kill.

His crimes were unconscionable. Robert Frederick Carr III kidnapped fifteen people, raped and tortured most, and murdered four before being arrested. He was also charming and personable, the perfect lure to draw in his next victim. After confessing to his grisly crimes and spending his life in prison, Carr begged Edna Buchanan, the police reporter for the Miami Herald, to sit down with him, interview him, and write about him, to help prevent his crimes from ever happening again. What she discovered was a genuinely intelligent sadist, a soulless predator who left a wife and children for an odyssey of violence. Her retelling of Carr's story is a chilling look into the mind of a killer.
