Could the employee of the press center of the Internal Affairs Directorate Katya Perovskaya have thought that the most ordinary sauna could become a real vision of hell. Of course, four hanged young men are swinging over the pool. Even the seasoned head of the “homicide” department, Nikita Kolosov, got goosebumps from such a spectacle. What about the man with a knife in his chest found in a nearby cemetery? What about a photograph of a group of sophisticated ladies and gentlemen sitting at a luxuriously decorated table, in the center of which lies a corpse in a tuxedo? There is no doubt - all these are links of one chain, but where, into what jungle of human passions does this chain lead? What kind of dark flame is raging there and demanding more and more victims? Questions, questions, questions... And the answer, as always, is unexpected and... creepy.
