In the heady days of the Jazz Age, Sherlock Holmes has retired to his bees. But other, stranger detectives watch London in his absence.
Chief among them is Charles St. Cyprian, the current Royal Occultist and heir to a tradition reaching back to Elizabethan England. He, along with his apprentice Ebe Gallowglass, protect the Empire and sundry from That Which Man Was Not Meant to Know—including vampires, ghosts, werewolves, ogres, fairies, boggarts and the occasional worm of unusual size.
Tonight, St. Cyprian’s night out has been interrupted by two very important men, Harry Houdini and Sir Arthur Conan Doyle. The escapist and spook-buster has a problem–a spook haunting his hotel room, a spook he can’t quite bust. And it seems this particularly ghost has a baring on a case Sherlock Holmes failed to solve, and may solve yet, if St. Cyprian doesn’t untangle the mystery first.
