In this book, professional counselor Todd Grande applies personality theory to over a dozen of the most notorious serial killers in modern history, unraveling the mystery surrounding their crimes.

Serial killers are typically motivated by sexual domination, money, or political ideology, or experiencing psychosis. Dr. Grande delves into the thought processes, behaviors, and emotions of these criminals, analyzing common personality traits as well as environmental factors such as childhood stressors and even certain kinds of injury. Empirically supported principles create a framework that offers new insight into why people do what they do and how they might recover from destructive patterns.
