In a cold spring of 1886 in St. Petersburg, a completely mysterious murder occurs of a young man from a wealthy family. There is no one to look for the killer: the detective clerk cannot unravel mysteries, and Vanzarov died suddenly six months ago and is buried in a closed coffin. Apollo Lebedev tries to apply the methods his friend used so simply and easily. But for the great criminal expert, it doesn’t work to become a great detective. What’s worse—Lebedev is waiting for another mysterious victim at the famous hotel. Not a single clue, not a single lead, no trace at all. The forensic expert falls into despair. Only a miracle can save him. Who will help Lebedev? How will the dead Vanzarov enter an unrelenting duel with evil? And what does the ancient myth of Orpheus have to do with it?
