Molly crouched behind the inflatable bounce house, studying the gymnasium through binoculars. Balloons covered every surface like a explosion had occurred in a party supply factory. Children shrieked with the intensity of tiny banshees while parents stood around sipping lukewarm punch, oblivious to the criminal mastermind in their midst. Bill approached, dragging a stolen catering uniform behind him. His shoes squeaked against the polished floor. "This is insane," Molly whispered. "Completely insane," Bill agreed, buttoning up the jacket. The present table sat against the north wall, surrounded by a moat of streamers and a guard made entirely of a six-year-old eating cake. This was their opening. Molly had mapped escape routes through the kitchen, past the bathroom where someone had inevitably clogged a toilet, and out through the loading dock. Bill smoothed his fake mustache, which was already peeling at the corners. A piƱata swung overhead like a pastel pendulum of doom. They could hear the birthday girl shrieking something about unicorns. "Ready?" Molly asked. "Let's steal some action figures," Bill replied. They moved forward into the chaos, two professional criminals about to commit the most ridiculous heist of their careers.
