Molly studied the mansion through opera glasses, though it was only a suburban bungalow and the nearest opera was three counties away. In the garden, balloons bobbed above a sign reading HAPPY BIRTHDAY, TIMMY, while children shrieked around a magician dressed as a suspiciously sweaty rabbit. Bill crouched beside her, wearing a tuxedo two sizes too small and carrying a gift-wrapped crowbar. “We go in disguised as entertainers,” Molly whispered. “What are we entertaining?” “Our exit strategy.” Their plan was simple: mingle with the parents, locate the mountain of presents, and replace every expensive toy with a carefully labeled IOU. Unfortunately, Bill’s disguise had already failed. A toddler pointed at his shoes and announced they were “criminal shoes.” Molly marched toward the gate with confidence borrowed from people who had never been arrested at a children’s party. Bill followed, wobbling beneath a balloon bouquet that repeatedly smacked him in the face. At the refreshments table, Molly distracted the host by asking whether the cupcakes contained traces of responsibility. Bill slipped toward the presents, but the magician’s rabbit blocked his path. “Password,” said the rabbit. Bill panicked and whispered, “Tax deduction.” The rabbit sighed and let him pass. Inside, Bill found the gifts guarded by Timmy’s grandmother, who slept with one eye open and a plate of cookies in her lap. Molly arrived pushing a cardboard box labeled EMERGENCY PUPPETS. It contained three stolen teddy bears, a kazoo, and Bill, folded painfully in half.
