He didn't just kill. He's been hunting for years. No noise. Without traces. Sergey Golovkin is one of the most brutal serial killers of the twentieth century. He was nicknamed "Fisher": he pulled the victim out like a fish on a hook and disappeared. 95 volumes of the criminal case — 95 "books of hell" full of blood, pain and fear. The testimony of more than 100 witnesses, dozens of interviews, countless photos and videos from the crime scene — all this formed the basis of a colossal journalistic investigation. Alexander Rogoza, a special correspondent for Komsomolskaya Pravda, studied interrogation protocols, diagrams, crime scene footage, and memories of witnesses and loved ones. How did a quiet and introverted boy turn into a violent predator? Why couldn't they find him for so long? Did even the closest people really not know about anything? Is it possible to "cure" a maniac if he seeks help in time? The gruesome details of this story are impossible to forget. But there is still a consolation in it: justice exists.
