If there's one serial killer that still captivates today it's Jack the Ripper, whose brutal, almost ritualistic killings sent chills through the residents of the cobbled streets of London, England, in 1888. The crime has gone unsolved for over 130 years, but that may be about to change when Scott Wolter gets a tip about a SENSATIONAL NEW SUSPECT, suggesting that the true identity of Jack the Ripper may be none other than ARTHUR CONAN DOYLE, the famed author behind Sherlock Holmes. Scott turns detective to follow symbols pointing to a secret rite in Freemasonry, clues at a hidden tunnel beneath London, and Conan Doyle's Masonic apron that may be stained with new evidence.
