1333. Mysterious events are unfolding in the capital of the Golden Horde. A guest has vanished from a room locked from the inside at an inn. Who is the foreigner who arrived in Sarai, calling himself a traveler from the sunset lands? Who is involved in his mysterious disappearance: sorcerers from secret dwellings in the Mordovian forests, Bulgarian merchants or papal envoys? Why is the beloved wife of Khan Uzbek, the domineering and treacherous Taidula, concerned about his fate? Sorting all this out is entrusted to the assistant of the emir of Sarai. He does not yet know how far his investigation will lead him.
