This is among the most useful books in my crime library. Gregg McCrary and Katherine Ramsland have written a fascinating can't-put-it-down study of his cases while he was an FBI profiler - one of the best and most well-known of a distinguished group of people.

It's exceedingly well told and tightly written, and the cases themselves are stunning - none more so than the story of German serial killer Jack Unterweger, the most terrifying murderer I have ever read about. Mr. McCrary's role in the inve...more

The Unknown Darkness is definitely a good read! I highly recommend it if you're really interested in psychology and criminology. So far, this is the best profiling / crime book I’ve read. This book goes in depth about the mind of psychopaths and how you can learn to think like them. It teaches you techniques along the way of how you can learn to be one step ahead of the criminal. He writes about his accomplishments, and even his failures. This book is good for information of what it’s like to be...more
I have read all of John Douglas's books (I think) and a couple by Robert Ressler, so I was intrigued to come across this book written by someone who worked in the same unit as both men. Douglas and Ressler clearly had a falling out, as they tell overlapping stories with little or no acknowledgement of the existence, let alone input, of the other. I was hoping McCrary's book might shed some light on that. To my disappointment and his credit, it really didn't.

Several of the stories recounted here...more
I have read a lot of profiler books and this was pretty good. I find that profiling books are really more about the actual case then they are about the actual process of profiling. This book went into a little more detail about profiling and how they've come up with the data they have and how they make determinations on suspects. It was an easy read and was pretty informative. I liked that the author integrated other literature into his assessments and addressed some of the major critiques about...more
The book I read is called The Unknown Darkness: Profiling the Predators Among Us by Gregg O. McCrary. It is a true crime book. The main theme is crimes that happen in every day lives that you don’t hear about and how you solve them by following an investigator through his job.

In the book there are a series of different stories that connect by one thing the investigator. Gregg O. McCrary investigates serial rapes, mass killings and hangings.Throughout the book he brings in these stories while inv...more
Gregg McCracy is a profiler with the FBI's Behavioral Science Unit (made famous by "Silence of the Lambs") and here, he takes us behind the scenes of notable FBI investigations including the Sam Sheppard and Arthur Shawcross cases. He explains the steps of a normal criminal investigation and how profiling fits in. He also delves into religiously-based offenses such as David Koresh's standoff with the ATF in 1993 and the massacre of Buddhist monks at a temple in the United States. Along the way,...more
To be honest I was glad to be done with this book. I have only given it 2 stars because I didn't necessarily like it but was compelled to read it. While the case stories are fascinating, they are also bleak and very gruesome. A lot of the cases are sexually sadistic killings and the details really turned my stomach as did some of the photos. Also the set-up of the book was a little frustrating - the first case story drew me in but was unresolved at the end of the chapter and then the author did...more
This is fascinating. If you like the TV show Criminal Minds, you'll love this. It's written by a former FBI profiler and it gives whole new insight to the Waco (David Koresh), Sam Sheppard, Scarborough Rapist and other less well-known cases.

There are clearly criminal types who need to be identified early and never allowed to roam the free world. These are psychopaths, dangerous people who cannot be rehabilitated. Therapy often makes them more dangerous because they take what they learn to better...more
McCrary, a former FBI profiler, talks about his most famous cases, including a Buddist temple massacre, a serial rapist who becomes a killer, and a re-examining of the Marilyn Sheppard case.

Enthralling, though a little hard to read. Sometimes a little disjointed, but stands on its own.

I really liked this book! It offered a new perspective on some well known crimes. The perspective was from the inside, of someone personally involved in the cases and that made it very interesting. I would recommend this for anyone who reads true crime.
Pretty good! There were spots at the beginning that dragged just a little, which is pretty much all that kept it from being five stars, but it is well-written and interesting
Looks into habits of Psychos and how they can be caught. Dont read if you are squemish about descriptive murders and such....... however this book is highly intellectual
Very good read, graphic details and informative narratives. Written in a way that is easy to understand and light for reading. Recommended for CSI enthusiasts.

I took a class with Gregg McCrary (the author) for my masters and it was excellent. I highly recommend this book.
Wonderful book written in almost a textbook style. A truly great analysis of the Sam Sheppard case at the end.
