'The Valley of Fear' is the fourth and final novel written by Sir Arthur Conan Doyle featuring his greatest creation: the world's first and finest consulting detective, Sherlock Holmes.

In this adventure, Holmes receives an encoded message from an agent of Professor Moriarty that a man's life is in danger. When that man is subsequently murdered, Holmes insists to the authorities that Moriarty is not merely responsible for the murder, but is in fact a criminal mastermind. Moriarty, however - who has carefully constructed a benign public persona - appears to all the world to be an innocent man. With no actual evidence to prove his claims, Holmes' accusations fall on deaf ears.

Thus begins one of the most thrilling and twist-filled adventures from Sherlock Holmes and his faithful companion Dr. John Watson as Holmes pursues the evil kingpin Professor Moriarity and attempts - at last - to bring him to justice.  

'The Valley of Fear' is presented here in its original and unabridged format.
