From John E. Douglas and Mark Olshaker comes a chilling true crime exploration of the psychology behind some of the world’s most dangerous offenders.

Drawing on his experience as one of the FBI’s pioneering criminal profilers, Douglas examines cases driven by obsession—where fixation, control, and compulsion escalate into violent behaviour. Through real-life examples, he breaks down how these offenders think, how patterns emerge, and how investigators work to understand and stop them.

Blending case studies with psychological insight, the book offers a fascinating look into the minds of criminals—and the investigative methods used to track them down.
