On a rainy morning, the body of a deputy commander of the MUR was found in a vacant lot. Some officers decided it was a domestic matter. And only detective Lev Gurov was sure the deputy commander was taken out by his own—“werewolves” who are tied to crime. And he began developing precisely this version—when, all of a sudden, the murderer turned up to confess. It turned out that the murdered deputy commander had an affair with his wife, and the jealous husband killed the rival. But Gurov found the story unconvincing. The detective felt in his bones that some dirty game was going on.
