Better known are the earlier dark works of Edgar Allan Poe. His brilliant and eccentric detective C. Auguste Dupin, a forerunner of Arthur Conan Doyle's Sherlock Holmes, appeared in works such as "The Murders in the Rue Morgue" (1841), "The Mystery of Marie Rogêt" (1842), and "The Purloined Letter" (1844). With his Dupin stories, Poe provided the framework for the classic detective story. The detective's unnamed companion is the narrator of the stories and a prototype for the character of Dr. Watson in later Sherlock Holmes stories.
