HarperCollins is proud to present its incredible range of best-loved, essential classics. 'In calling Moriarty a criminal you are uttering libel in the eyes of the law-and there lie the glory and the wonder of it! The greatest schemer of all time, the organizer of every deviltry, the controlling brain of the underworld, a brain which might have made or marred the destiny of nations - that's the man!' First published as a serialisation in the Strand magazine between 1914 and 1915, The Valley of Fear depicts Sherlock Holmes in his very first brush with his arch nemesis, Professor Moriarty. Summoned by one of Moriarty's henchmen to a mysterious manor house, Holmes and Watson find themselves confronted by the scene of a brutal murder. But the brilliant Holmes soon reveals that there is much more to this case than first meets the eye... The fourth and final Sherlock Holmes novel, 'The Valley of Fear' will undoubtedly delight fans of Conan Doyle's legendary detective and his faithful sidekick Watson.
