It is enough to stumble once to forever receive a stain on your immortal soul. But it’s a no small sin to testify perjury at a trial for the murder of a girl. And the fact that quick destruction comes to the sinner will not be a relief - it is only the beginning of paying the bills. The remaining debts to the universe will have to be repaid by the victim, who finds himself in the body of a police officer, college secretary Ignat Dormidontovich Silaev, in a parallel reality, hunting crazy strigas, fighting off werewolves and taming brownies. At the same time, it is still necessary to somehow avoid too close attention of the imperial gendarmerie and the Orthodox Inquisition.
