Is Whoever Fights Monsters Worth Reading?
My Twenty Years Tracking Serial Killers for the FBI
Ada’s Score
Robert K. Ressler, one of the FBI agents who invented criminal profiling, offers a riveting first-person account of interviewing some of America's most notorious serial killers, including Ted Bundy, John Wayne Gacy, and Jeffrey Dahmer. Published in 1992, the book traces the development of the FBI's Behavioural Science Unit and the techniques of criminal profiling that would reshape law enforcement. Ressler writes with candour about the psychological cost of this work as well as the bureaucratic battles within the FBI itself. It is both a foundational text in forensic psychology and a page-turning insider narrative.
“The book that basically invented the true crime genre as we know it. Ressler's candid voice makes it feel like a conversation with history.”
