The most famous Russian profiler about Chikatilo, Mokhov, Popkov, Iskhakov, Pichushkin and other maniacs.– How to recognize a maniac and not become his victim?– Like psychopathic killers appear?- Why do they commit their crimes?- How does the killer choose his target?- What goes on in his head?These and other questions are answered in her book by profiler Anna Kulik, who draws up their psychological and behavioral portraits from conversations and observations of criminals and helps investigators find the criminal and understand his motives.“Thoughtfully. Penetratingly atmospheric, slightly noir, but honest and informative. The theme of maniacs and serials is not simple and is often quite ambiguously perceived by the audience. Despite the fact that a lot has been said, filmed and written about it, 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 her work. 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.“The book made a strong impression on me. Written professionally, with knowledge of the subject. Easy to read. The author has done a great job. Before starting a fascinating story about individual criminals, she introduces readers to the basic concepts of who serial killers and maniacs are. Expanding these concepts, Anna Kulik relies on the opinions of many well-known experts in this field, such as Antonyan, Bukhanovsky and others. In the relevant chapters, the author convincingly describes the process of how specific individuals became maniacs. I would recommend this book to investigators and anyone interested in criminology.” – AMURKHAN YANDIEV, retired Colonel of Justice, participated in the capture of serial killers Chikatilo, Mukhankin and other criminals.
