If you were arrested in a department store for shoplifting in the 1950s and 60s, it was probably by a female store detective, then referred to as a floorwalker. These middle-aged women were tough, quick on their feet masters of retail surveillance. They'd blend into the shopping environment then spring into action to apprehend the unsuspecting thief. It was a dangerous job that took skill, stamina, focus, and courage. These anonymous crime fighters were the unsung heroes on the front lines of American law enforcement.
