Legendary profiler and bestselling author Douglas (Mindhunter), who pioneered the FBI's systematic study of serial killers, offers his insights into one of this country's most chilling killers—Dennis Rader, a seemingly innocuous family man and municipal employee, whose brutal murders terrorized Wichita, Kans., for three decades. Identifying himself by the initials BTK (for Bind, Torture, Kill), Rader (who in 2005 pled guilty to 10 murders and is serving consecutive life sentences) taunted the press and law enforcement, striking at random in savage attacks that often decimated families, and then confounded his pursuers with long dormant periods. With the aid of People magazine writer Dodd, Douglas nicely weaves the story of his own development as a profiler with the history of BTK's crimes and his own role in the investigation, drawing on analyses he developed early on in the rampage; he noted, for instance, “the razor sharp control” the killer maintained after his crimes. While the stomach-turning story of BTK's crimes has been told by others, Douglas's unique professional experience and his exclusive personal access to Rader offers a different perspective, even as the answer to the question of how such a monster comes to be remains elusive.
