Molly crouched behind the garden hedge, peering through the gap at the bouncy castle that dominated the backyard. Streamers floated lazily in the afternoon breeze. A banner reading Happy Birthday Timmy swayed between two oak trees. She counted approximately forty children running around like sugared-up tornadoes, which, she noted grimly, was exactly what they were. Bill crawled up beside her, twigs stuck in his hair and mud on his chin, clutching a clipboard he had absolutely no need for. "Twelve presents," he whispered. Molly nodded, scanning the patio where a mountain of wrapped gifts sat beside an untended folding table. The parents were inside, probably desperately pouring wine. The clown hired for entertainment had already retreated to his van, and she could not blame him remotely. The plan was straightforward enough. Bill would create a distraction involving balloon animals gone catastrophically wrong. Molly would load the gifts into the wheelbarrow they had hidden behind the garden shed. They would be gone before anyone noticed, slipping away through the side gate while Timmy was still demanding his third helping of cake. It was, Molly thought with some shame, their most elaborate and morally questionable job yet.
