Molly studied the suburban battlefield from behind a hedge shaped like a surprised rabbit. Balloons bobbed over the garden fence; a hired magician was unloading rabbits with the grave expression of a bomb technician. On the patio, mountains of wrapped presents glittered beside a pink castle cake large enough to require planning permission. "Forty boxes," Molly whispered. "Fifty, counting the giant dinosaur. One squeaks." Bill swallowed. "Then we move fast, smile kindly, and fear glitter first, always." He adjusted his black turtleneck, which in daylight made him look less like a master thief and more like a depressed mime. Molly unfolded the blueprint: back gate, trampoline, juice table, and, at the center, the gift pile, guarded only by six-year-olds with sugar in their veins and whistles in their pockets. Their timetable was elegant. During musical statues, Bill would crawl under the trestle table and cut the ribbon netting. During pass-the-parcel, Molly would roll in the emergency wheelie bin, line it with a pirate tablecloth, and sweep the loot inside. Exit route: through the bouncy castle, over the paddling pool, into the alley before anyone noticed two extra adults. Inside, children sang off-key, and Bill looked ready to confess everything immediately.
