The year is 1922. A respected judge inexplicably vanishes in a decrepit mansion and two of the world's most remarkable men are summoned to investigate: Sir Arthur Conan Doyle, creator of Sherlock Holmes, and Harry Houdini, the world's greatest escape artist. Aided by a beautiful, young psychic, the unlikely partners probe a mystery that becomes murkier and more perilous at every turn and brings them face to face with evil incarnate. To solve the riddle of The Spook House - and to survive its dangers - they must call upon all of their extraordinary mental and physical powers. The story draws upon the real-life friendship of Conan Doyle and Houdini, two vastly different men brought together by their fascination with the paranormal.
