Killer

Adapted from real cases. Plot synopsis: In Wroclaw, Poland, in 2000, a man was brutally murdered, but the police investigation reached a deadlock. Three years later, a novel called "Amok" was published. The plot in the novel and the details of the murder were surprisingly consistent. The police received an anonymous report, and Detective Jacek immediately intervened in the investigation. What is the truth? Is there really an inextricable connection between the original author of the novel and the murder?
