Where the descendants of the ancient gods rule, you will not surprise the risen dead! Undead with evil spirits is the concern of the police. The Petersburg detective, who got deeply into the secrets of the reigning house of the Dazhdbozhichi, either as a reward or as a punishment, was appointed head of the provincial Police Department. Wheels knock on the rails of the new railway, terrible shadows rise above the ancient burial grounds, bloody and dirty secrets hide behind the walls of neighboring estates. But he brings the most important, most dangerous secret with him - his son, Mitya. A descendant of an ancient family shakes off dust particles from a fashionable frock coat, longs to return to St. Petersburg, frowns disgustingly at the sight of provincial morals and... hides a silver-plated dagger behind a sleeve flap.
