Molly adjusted her fake mustache as Bill studied the blueprint of the community center. "So we go in through the bounce house?" Bill whispered. "That's the beauty of it," Molly grinned. "Nobody suspects the bounce house." "What about the security?" "Two retired mall cops. One's probably napping, the other's distracted by the pizza table." Bill nodded, impressed. "When do we move?" "During the piƱata chaos. That's our window." They watched from across the street as tiny humans in Batman costumes arrived with their parents. Molly's heart raced. After years of robbing museums and banks, she was about to commit the perfect crime. "The bicycle alone is worth three hundred dollars," Bill said, pointing to the gift pile. "Don't forget the gaming console. That's the real prize." A child laughed from inside the center. Molly felt a twinge of conscience. "Are we really doing this?" Bill asked, as if reading her mind. "We're professionals," Molly replied firmly. "Besides, these kids have too many presents anyway." "True. Action figures everywhere." They synchronized their watches. Operation Birthday Bash was a go. Neither anticipated that the birthday girl's father was actually an undercover cop.
