Learn moreFirst published in 1890, The Sign of Four is Sir Arthur Conan Doyle's second book starring legendary detective Sherlock Holmes. The story is complex, involving a secret between four ex-cons from India and a hidden treasure. More complex than the first Holmes novel, The Sign of Four also introduces the detective's drug habit and leaves breadcrumbs for the reader that lead toward the final resolution.
Sir Arthur Conan Doyle (1859-1930) was an English novelist known chiefly for his series of tales featuring the detective Sherlock Holmes. He also wrote the historic novel, The White Company, and the imaginative fantasy The Lost World.
