This is not a book for the faint of heart. It is surprising that I have not picked up books by this author(s) before, considering that I have watched multiple serialized versions of their findings on TV and NetFlix. It was a little hard to get through the first section because of the detailed descriptions of the crime but the other three were comparatively less brutal.
This book consists of four cases of killers with references to other similar ones within the section itself. John Douglas details the conversations he has with these criminals to identify traits and patterns that might ultimately work towards something positive in the future. I found it easy to read the actual narration of the thought process (if not the details of the crime) and understood the need to convey the psychological aspects that might be the underlying cause. The summation at the end of the book, however, made me understand the point of the whole exercise and the collection of these otherwise macabre events.
I have only read a few true-crime books but this was one of the better ones. I would (at some later stage) check out more books by the author.
This book is set to release on May 7th 2019. I received an advance copy thanks to NetGalley and the publishers but the review is completely my own opinions.
