Murder on the Leviathan (Russian: Левиафан ("Leviathan"); British edition titled Leviathan) is the third novel in the Erast Fandorin historical detective series by Boris Akunin, although it was the second book in the series to be translated into English. Its subtitle is герметический детектив ("hermetic detective"). Akunin conceived of the Fandorin series as a summary of all the genres of detective fiction, with each novel representing a different genre. Leviathan is his nod to Agatha Christie's style, with an exotic setting, a cast of unusual characters who each have secrets of their own, and a strange murder to start the action.
