4.0

If Ted Bundy, Ed Kemper, John Wayne Gacy, or Jeffrey Dahmer are of any interest to you, this is the book to read. This first-hand account from the FBI agent who coined the term "serial killer" gives unique insight into the development of profiling by delving into the crimes and minds of America's most infamous killers.

My one criticism is that (as with most books with autobiographical components), Ressler comes off as slightly haughty at times. Then again, why shouldn't he? He developed the basis of everything we know about serial killers today. Great book. A must-read for anyone interested in true crime.
