"The valley of fear, the valley of death. The terror is in the hearts of the people from the morning to the night."

A cipher message from a mole in Professor Moriarty's organization warns Sherlock Holmes of a looming danger to a country gentleman named John Douglas. Before Holmes can act, news arrives of a gruesome murder at Birlstone Manor -- a moated house where the victim was killed with a bizarre American weapon. The room is locked, the drawbridge is up, and yet the killer has vanished.

The Brotherhood of Terror: The investigation takes a sudden, cinematic turn across the Atlantic to the coal mines of Pennsylvania. Here, the "Valley of Fear" is ruled by a murderous secret society known as the Scowrers. Through the eyes of the daring Jack McMurdo, readers witness a world of infiltration, betrayal, and high-stakes espionage that predates the modern noir thriller.

Holmes's Darkest Rivalry: Unlike other Holmes adventures, The Valley of Fear highlights the terrifying reach of Professor Moriarty. Even from the safety of London, the "Napoleon of Crime" pulls the strings of a global web of violence. This novel is a relentless, two-part epic that proves that even in the most isolated corners of the world, no one is truly safe from the consequences of their past.

Two worlds. One secret. A trail of blood that spans an ocean. Purchase "The Valley of Fear" today and see if you can outguess the Master of Deduction.
