John Douglas spent 25 years at the FBI, and it nearly cost him his life. In his book "Mindhunter: Inside the FBI's Elite Serial Crime Unit," you quickly understand why. Douglas was one of the original profilers who was using Behavioral Science to identify and ultimately profile some of America's most notorious killers. Douglas takes you behind the scenes of some of his most gruesome, fascinating, and challenging of the cases he worked. He also explains confrontations and interviews with some of the most feared killers the U.S. has ever known, men like Ted Bundy, Charles Manson and the Son of Sam. "Mindhunter" by John Douglas and Mark Olshaker is this week's entry on Rick's Reading List.
