In the autumn of 1916, Petr Dmitrievich Insarov, a high-ranking officer of the criminal investigation in Petrograd, investigates a series of daring raids. The circumstances of the crimes feel steeped in mystery: it seems the gang isn’t made up of ordinary people. But a familiar investigator who knows the supernatural has never encountered such “oddities.” Clues lead to the famous poet Nikolai Gumilev, who has just returned from the front and somehow is connected to what’s going on… The novella is a standalone story that can be listened to without knowing other works from the Insarov cycle.
