Molly crouched behind the hedge, wearing a caterer’s apron and the expression of a woman who had recently learned that balloon animals could be used as zip ties. Bill waited beside her, disguised as a clown by means of one red nose and deep emotional regret. His makeup had begun sweating elaborate accusations. Across the lawn, fifty children screamed around a magician whose rabbit had clearly joined a union. “Molly, why rob a child?” Bill whispered. “We’re rescuing presents from sticky fingers and noisy toys.” A banner declared HAPPY BIRTHDAY, while a pony chewed through the gift table’s leg with patient criminal efficiency. Molly studied the window. Inside, wrapped boxes glittered beneath a plastic castle. Her blueprint, drawn on a napkin from a fish restaurant, showed three exits, two parents, and one unforgiving grandmother guarding the cupcake tower. “Bring the van,” Bill said. “And the cake.” Molly adjusted her apron. The plan was simple: slip inside during the magician’s finale, load every present into laundry hampers, and escape through the bouncy castle, which offered both cover and plausible screaming. Then the rabbit hopped onto Bill’s shoe, stared at him, and produced a tiny police whistle from nowhere.
