Sherlock Holmes is a fictional detective created by Sir Arthur Conan Doyle. Holmes is renowned for his astute observatory skills, deductive reasoning, and logical analysis. He is recognized for his flair for the dramatic and often shows a lack of emotion, sometimes to the point of appearing callous. Sherlock Holmes is a violinist and enjoys smoking a pipe, frequently using tobacco as a means to think and deduce. He resides at 221B Baker Street, London, with his roommate and chronicler, Dr. John H. Watson. His archenemy is the criminal mastermind Professor Moriarty. Holmes is also known to have many contacts in London’s underworld who provide him with information.
