This book is brief summary of the crimes, capture and history of some of the most notorious serial killers. People heavily read or educated in this fields might find this simple or surface level. However for me I thought this was an interesting. It provided top level overview of the killers and their crimes in an engaging and easily accessible writing style. This is written for the novice in a very criminal minds esc way. It was a three star from me as there was nothing original to this writer, no new research done by him, or new evaluations or analysis by him, it was more of a summary of other research. So while interesting, it was not unique nor offering anything new. Also the information about Jack the Rippers victims has since been found to be incorrect they were not all prostitutes so some factual inaccuracies.
