A cryptic message. A brutal murder. A conspiracy that reaches across continents.

The Valley of Fear (1915), by Sir Arthur Conan Doyle, is the last full-length Sherlock Holmes novel and one of his darkest tales.

Holmes and Dr. Watson are called to investigate the violent death of a country gentleman, only to uncover a mystery tied to a secret society, betrayal, and revenge. With its chilling atmosphere and intricate plotting, the novel combines a classic detective story with a dramatic backstory of crime and corruption.

Most notably, Holmes once again faces his arch-nemesis, Professor Moriarty, whose shadow looms over the case -- proving that no crime is too distant, and no criminal too powerful, for Holmes' keen intellect.

Blending suspense, deduction, and high drama, The Valley of Fear is a gripping conclusion to the Holmes novel canon.
