I've never read Sherlock Holmes, but did his character know martial arts like kung-fu or karate or similar? You hear about it when Holmes tells Watson about fighting Moriarty at Reichenbach Falls. He says he used Baritsu. Conan Doyle actually meant Bartitsu which was a version of jujitsu brought to England by a guy named Barton. Usually he had Watson bring along his service revolver but I don't remember a great deal of shooting in the stories. Jim
