Annotation from liters When it comes to serial killers, the main question is not “Who?”, but... “Why?” What made them commit deliberate cruelty? In the FBI, the search for an answer to this question lies entirely on the shoulders of special employees - those who work on psychological portraits of maniacs and, through long conversations with criminals, reveal their true nature and motives.

Former FBI agent, one of the first American criminologist and best-selling author of criminal psychology John Douglas compares this labor-intensive process to a psychological chess game without pieces, a non-contact sparring contest of endurance in which each side seeks to take advantage of the weaknesses and insecurities of the other. Together with screenwriter and author Mark Olshaker, Douglas has published a number of nonfiction books detailing his work for the FBI as a behavioral psychologist and investigative analyst.

The Killer Sitting Opposite is not just a book revealing the character thoughts of dangerous maniacs and tells how the FBI exposes serial killers. In fact, this is a collection of conversations that Douglas had, because it was thanks to them that he realized that understanding the mindset of an aggressive criminal can help law enforcement agencies catch him and bring him to justice.

Book description Four criminal cases and four dangerous ones maniacs who, without sympathy or remorse, coldly took the lives of other people. Who were they before imprisonment and why did they decide to kill? In a tiny interrogation room, former FBI agent John Douglas talks to each of them and tries to understand how crimes are born. Analyzing case materials, biographies and the psychological state of killers, he talks about how they think and what motivates them.
