The Valley of Fear

An Apple Books Classic edition.

Arthur Conan Doyle’s final Sherlock Holmes novel pairs a country house murder with a brutal chapter from America’s labor wars.

When a man is found dead in an isolated English manor, Holmes discovers coded warnings and signs of a secret society. The investigation leads back across the Atlantic to the coal mines of Pennsylvania, where violence, covert alliances, and desperation have shaped lives for decades—and where the roots of this murder were planted years ago.

Holmes traces how fear tightly binds people together and how old debts eventually come due. Dark and morally bracing, The Valley of Fear shows the detective confronting crimes that reach beyond any single villain, revealing how violence ricochets after the first blow.
