Southern Russia, the 1920s—the height of the Civil War. A young forensic doctor Egor Lisitsa dreams of solving crimes using the new science of forensics. Unexpectedly for himself, he is drawn into a swift whirlwind of events where espionage and huge money are mixed together, reds and whites, the nobility of a bygone century and cruel murders. As part of a small unit, Egor Lisitsa carries out an extremely important mission—delivering a valuable and secret cargo to the sea. But the mission is in jeopardy. Inside the unit, a cold-blooded criminal is at work. Egor is forced to fight him. The circle of suspects narrows, turning into a list of victims. Can knowledge of progressive scientific methods help the hero stand up to the “werewolf”? How will the intellectual duel between a yesterday’s student and a ruthless, sophisticated killer end?
