In the summer of 1994, a workman at the historic mansion of railroad baron James J. Hill in St. Paul, Minnesota, stumbles on a long-hidden wall safe. When experts arrive to open the safe and examine its contents, they make an astonishing discovery. There, inside, is a handwritten manuscript bearing the signature of John H. Watson, MD. The manuscript contains the story of how Sherlock Holmes and Watson traveled to Minnesota to track a murderous arsonist - known only as the Red Demon - who is threatening both Hill and his Great Northern Railway.
Set against the backdrop of the real, devastating Hinckley forest fire of 1894, Sherlock Holmes and the Red Demon is the tense and atmospheric first novel in Larry Millett's classic series of adventures that brought Sherlock Holmes and Dr. Watson to Minnesota.
