The book opens a series of mystical detective novels in which the true story of Sherlock Holmes and Dr. Watson will finally be told. They investigate mysterious and complex crimes in a realm beyond the reach of their other colleagues—crimes involving supernatural beings. And many of Conan Doyle’s famous characters themselves turn out to be ghosts, vampires, elves and even... a living medieval castle. And not only criminals have dark secrets, but also those who follow their trail... A mysterious stranger hires a military doctor, disillusioned with life, to witness the death of a strange viscount. He finds himself involved in a cycle of mysterious, mystical events and mysterious deaths, from which he can only get out together with his new friend. “What a week we had with you, John, we both died! But everything is just beginning!”
