The most famous Russian profiler about Chikatilo, Mokhov, Popkov, Iskhakov, Pichushkin and other maniacs. - How to recognize a maniac and not become his victim? - How do psychopathic killers appear? - Why do they commit their crimes? - How does a killer choose his target? - What happens in his head? Profiler Anna Kulik answers these and other questions in her book, which, from conversations and observations of criminals, compiles their psychological and behavioral portraits and helps investigators find the criminal and understand his motives. "Thoughtfully. Piercing atmospheric, slightly noir, but honest and informative. The topic of maniacs and serials is not simple and is often rather ambiguous perceived by the audience. Despite the fact that a lot has been said, filmed and written about this, the book allows you to look at already known stories through the eyes of a seemingly fragile girl, who in fact is not just a professional, but a person who is in love with his business. He is so in love that he is not afraid to go into the cell to the killer over and over again. After meeting Anna, I was even surprised that serial fighters with maniacs have prototypes not only among law enforcement officers, but also among such specialists." - KSENIA SOBCHAK, journalist, TV presenter.
