Awesome

This is a great book for understanding how criminal profiling works and the depth of depravity of compassion in a psychopath!

Robert Ressler Book

The book was fascinating. It gave a good insight into the origins of criminal profiling and leads the reader through a number of cases from Robert's career. A must read for people interested in abnormal psychology, forensics and profiling.

Looking into an abyss

I initially read this book when I was 19yrs old. For years I had read everything I could get my hands on regarding serial killers but none came close to this book. Now ten years later, I have yet to find a book on the subject that I thought did a more thorough job than this one. I was terrified reading it and found myself looking behind every corner and at every neighbor thinking he may be a serial killer!
