The Unknown Darkness: Profiling the Predators Among Us Paperback – September 28, 2004

In basement offices three stories below the ground at the FBI's Academy in Quantico, Virginia, former Supervisory Agent Gregg McCrary was among the first generation of the most elite force for criminal investigation in the world.

In The Unknown Darkness, McCrary takes the reader behind the crime scene to examine in raw first–person close–up the lethal competition between America's most dangerous predators and the dedicated souls who pledge to put them away. McCrary's 25 years in the Bureau have yielded over 1000 cases to draw upon. The 10 he describes in the book reveal the strengths and pitfalls of modern criminal investigation.

McCrary is not afraid to answer the questions most often skirted by the others: what happens at the crime scene, what kind of person does it take to grapple with the serial killers among us, and exactly how do we disarm the enemy?

McCrary continues to consult and provide expert testimony in cases in which crime scene analysis is key, and provides expert commentary to NBC, ABC, CBS, and CNN.

This book is extremely dark but well written. If you can't stand to hear tragic things or have nightmares easily, then do not read this book. I really like how the author writes and sections the book up. It's an easy and interesting read.

5.0 out of 5 stars Dealing effectively with untypical types of crimes
Reviewed in the United States on July 5, 2015

The author calls our attention to bizarre and spectacular types of crime. While not common, crimes like those the author describes do occur. Law enforcement procedures, however, are not very effective in detecting and solving them. This situation calls for more appropriate and effective training in both detection and prevention.

3.0 out of 5 stars Interesting enough insights, a bit tedious to read
Reviewed in the United States on January 2, 2005
I've read just about everything by John Douglas and other books on profiling, and am a bit of a Court TV junkie. This book provides new information and insights into criminal profiling and certain cases than previously available, and for that reason, I'd recommend it for a true crime fan. It provides new information on the Paul Bernardo / Karla Homolka husband and wife serial rape "team", the Buddhist Temple Massacre near Phoenix, and the Waco tragedy. The fact that McCary presents fairly convincing evidence that Karla Homolka was hardly the "battered wife" she's usually presented to be in this highly documented case was the most startling to me.

The problem is the writing is tedious to read at several points, and the chapter on the Waco stand-off seems to go on forever. The book could have used some more work by the editor, as some paragraphs don't really fit together and some of the narrative goes along in a herky jerky fashion. For this reason, I would not recommend this book for someone with just a passing interest in the subject.

I worked in the court system for thirty years and understand that there are very dangerous people in every community. The person standing behind you in Walmart may be one. We all need to be aware of the possibility of becoming victims, although we can't be paranoid about it.
