Molly and Bill crouched behind a hedge outside the community center, dressed as an aggressively festive pair of elves. Their getaway vehicle, a dented ice-cream van, wore a sign reading FREE SPRINKLES, though neither thief had considered sprinkles operationally necessary. Inside, children shrieked around a mountain of presents beneath balloons shaped like disappointed unicorns. Molly studied the entrance through binoculars borrowed from a birdwatcher who now suspected everything. “Wait for the cake distraction; then we grab presents and vanish,” Molly whispered. “Excellent, but frosting makes me sneeze like a cannon.” Bill nodded, accidentally ringing a tiny bell sewn to his collar. A toddler glanced over, applauded, and offered him a juice box. Bill accepted it with the solemnity of a diplomat receiving a treaty. Their plan involved replacing every present with carefully wrapped bricks, a scheme Molly considered ethically confusing. Unfortunately, the bricks were still in the van, under six hundred pounds of novelty sprinkles. At precisely three, Molly rolled toward the door inside a giant papier-mâché cupcake. Bill followed, pushing a sack labeled EMERGENCY BALLOONS. The cupcake snagged on a streamer, spun twice, and launched Molly into the punch bowl. She emerged purple, triumphant, and carrying three gifts. Bill seized a fourth, but its wrapping tore, revealing a toy police badge. He froze. From across the room, twelve children simultaneously saluted him.
