The Hound of the Baskervilles by Sir Arthur Conan Doyle is one of literature’s most renowned mysteries; Sherlock Holmes is on the case after a ghostly hound stalks, and perhaps kills, Sir Charles Baskerville. Written in 1901, it is now part of school curriculums and popularized in film and television. Yet despite cultural familiarity with the novel, the allegations of adultery, plagiarism, and murder that haunt its creation remain largely unknown.
