Sherlock Holmes? What is the darkness of Sherlock Holmes? He beat animals to death. "Sherlock Holmes was beating the subjects in the dissecting rooms with a stick to verify how far bruises may be produced after death. I say him at it with my own eyes." (From 'A Study in Scarlet' by Arthur Conan Doyle.) Sherlock Holmes was a vivisectionist with a passion for pains-taking knowledge.
