Sherlock Stalks The Joker An actor playing Sherlock Holmes believes he is the Great Detective when the Joker coshes him over the head with a pipe. Accordingly, he sees the Joker as Professor Moriarity, and goes on the hunt for him. Joker on the other hand, has set out to recreate some of the most famous crimes solved by the fictional detective and he is delighted to be confronted by the actor. On a couple of occasions, Joker manages to pull the crimes, outsmarting the fake Sherlock Holmes, but the Clown Prince of Crime eventually meets his match when Sherlock finds a vital clue thanks to his assistant, Watson, and captures the Joker for good.
