The English writer, publicist, and journalist Arthur Conan Doyle authored historical, adventure, and fantastic novels as well as works on spiritualism, but he entered world literature as the creator of the Greatest Detective of all time and people — Sherlock Holmes. A noble and fearless fighter against Evil, possessing a sharp mind and extraordinary observation skills, the detective solves the most complex puzzles using his deductive method, often saving human lives in the process. He brilliantly transforms himself, has an acting gift, and knows how to deliver a spectacular conclusion at the end of each brilliantly conducted investigation. The tireless Sherlock Holmes and his easily excitable friend Dr. Watson are dear to readers worldwide. This edition includes the novellas "A Study in Scarlet" and "The Sign of Four," as well as the short story cycle "The Adventures of Sherlock Holmes."
