According to Without a Clue, master detective Sherlock Holmes was a wholly fictional character. Well, we knew that; what we didn't know was that Holmes was a figment of the imagination of his chronicler, Dr. John Watson (Ben Kingsley). When Holmes' fame begins to grow, would-be clients besiege Watson's office for chance to consult the Great Detective. In desperation, Watson hires a seedy provincial actor (Michael Caine) to pose as Holmes. Trouble is, the preening actor hasn't got a clue -- about anything.
