Sherlock Holmes? He's a fraud! All you need to do is get inside his residence on Baker Street and discover what you've known all along - namely, that Holmes himself, along with that rotund and ridiculous sidekick of his, Dr Watson, commits the crimes and then 'solves' them, thereby achieving celebrity status and becoming the hero of the day. A little bit of proof that he's behind the crimes is all you need. It won't take much to expose him for the fraud he really is.
