The Valley of Fear

The Valley of Fear was previously published serially in The Strand Magazine in 1914–1915. In the final full-length Sherlock Holmes novel, the detective solves the murder of Douglas—a rich and locally popular gentleman—who had lived for years in the ancient, moated Birlstone Manor House. With no obvious motive or suspect, Holmes and Watson solve this baffling murder mystery that left behind a trail of bewildering clues: raincoats, dumbbells, and a missing wedding ring.
