Batman #279 Reprint

RIDDLER ON THE RAMPAGE The Riddler breaks out of jail, leaving a message for Batman in his bunk. Using a new tactic, he vows to inundate Batman with riddles. In this way he hopes to overload the hero's brain and make Batman unable to effectively oppose him.  Coincidentally, Dick Grayson is down from college to do research, and lends a hand as Robin. The Dynamic Duo battle two members of the Riddler's gang disguised as the Riddler himself in a clock museum, but the heroes a lured away from them, allowing the crooks to escape. Later, another clue leads them to a yacht club party, where they stop the Riddler from stealing a valuable ship model, but once again, they're unable to capture the criminal. Using the last riddle-clue left by the master criminal, the pair catches up to him at the Egyptian pavilion of the Gotham Art Museum, where he is trying to steal a solid gold model of the Sphinx. After capturing Riddler and his associates, Robin remarks that the Sphinx, one of the world's greatest riddles, seems quite appropriate for the caper.
