The Valley of Fear

Inspector MacDonald of Scotland Yard arrives to 221B Baker Street with a case: a Mr. John Douglas has been found murdered at a remote English manor.

As Holmes and Dr. Watson investigate, they uncover strange clues pointing to a shadowy secret society and a dark history that stretches across the Atlantic—all the way to a mining town in America. As the case deepens, so does the danger, testing the limits of both their wit and mettle.

The fourth and final of the Sherlock Holmes novels written by Sir Arthur Conan Doyle, The Valley of Fear was first serialized in Strand Magazine from September 1914 to May 1915.
