For the first time since the death of Sir Arthur Conan Doyle, a new Sherlock Holmes story has been sanctioned by his estate, whetting the appetites of fans everywhere. Information about the book will be revealed as deliberately as Holmes himself would unravel a knotty case, but bestselling novelist and Holmes expert Horowitz is sure to bring a compelling, atmospheric story to life.

From the gritty streets of nineteenth century London, the loyal and courageous Dr. Watson offers a tale unearthed after generations of lore: the harrowing story of Sherlock Holmes's attempt to hunt down Jack the Ripper.
