Detective Comics (1937-2011) #457

“THERE IS NO HOPE IN CRIME ALLEY!” Every night on this date, Batman abandons all other crimes and missions and secretly heads to visit Leslie Thompkins. En route, Batman stops a car-radio theft and two muggings. When one of the muggers pulls a gun on him in Crime Alley, Batman loses his temper and knocks the mugger silly while having a flashback to his parents’ murder and his “rescue” by a young Leslie Thompkins.
