Maxie Murdock was a gang leader who was active in the 1940s. In the fall of 1944, he worked on a synchronized plot to simultaneously rob a local jewelry shop and art gallery. Seeing the super-speedster known as the Whizzer as a problem, Murdock planned to have the robberies happen just seconds after a phony robbery of a bank. Since all three locations where in different parts of the city, Murdock believed that the Whizzer could not stop all three crimes. Sending one of his men to commit the bank robbery, Murdock -- taking the nom de plume of the "Crime Clocker" -- gave his minion a letter detailing his plot to mock the Whizzer when he caught the would-be bank robbery.
Murdock did not anticipate that the Whizzer would be able to beat the location of the other two crimes out of his minion and stop them. The Whizzer foiled the jewelry store robbery and then allowed the art thieves to escape so that he could be led to their employer's hideout. Leading the Whizzer right to Murdock's mansion led to the downfall of the Crime Clocker, with the Whizzer easily trouncing Murdock and his men and turning them over to the authorities.
Murdock's subsequent activities are unknown.
