1906 Empress Alexandra Feodorovna entrusted Prime Minister Stolypin with an unusual task. Two years ago, the miraculous icon of the Kazan Mother of God was stolen from a convent in Kazan. The police found the thieves, but were unable to find the relic itself. There were persistent rumors in society that the image was intact and hidden somewhere. Stolypin sent the best detective of the Police Department, collegiate adviser Lykov, to search for the icon. The detective went to Kazan. But as soon as the investigation began, terrible events began to occur in the city.
