Holmes vs the Joker?
Everyone knows that Sherlock Holmes appeared in Detective Comics #572 in 1987, an anniversary celebration issue commemorating 50 years of Batman, which happened to coincide with Holmes’s own centennial. One segment of the story takes place in the Victorian era, where Holmes and Watson uncover a conspiracy masterminded by Professor Moriarty which has ramifications in the present day for Batman and fellow DC universe sleuths Slam Bradley and Ralph Dibny, aka the Elongated Man.
Did you also know, though, that Holmes clashed with Batman’s nemesis the Joker in issue #6 of the Clown Prince of Crime’s own shortlived mid-’70s solo title? Well, no, he didn’t, not really. In fact, it’s a stage actor playing Holmes who, having received a knock on the head from the Joker, deludedly believes he is the genuine article. Dennis O’Neil’s capersome story is littered with sly, punning Holmesian references.
