Molly spread the blueprint across the van's hood, smoothing the creases with the reverence of a surgeon unfolding a patient. It was, technically, a hand-drawn map of the Pemberton backyard, rendered in crayon because that was all Bill had found in the glovebox. The bouncy castle was labeled OBSTACLE. The piƱata was labeled OPPORTUNITY. Bill studied it while eating a sausage roll, dropping flakes of pastry onto the parking lot like a man leaving a trail for his own rescue. He tapped the northeast corner, where Molly had drawn a lopsided figure in enormous shoes. "The clown's the weak link," he said. Molly nodded. Clowns were always the weak link. Underpaid, overheated, spiritually hollowed out by decades of unrequited laughter. A clown could be bought for forty pounds and a compliment. The presents, she explained, would be stacked on the trestle table beneath the banner, guarded by nothing more formidable than a grandmother with poor depth perception. Twenty-two children, one exhausted father, and a magician arriving at three. They would enter at two-fifty, disguised as the magician's assistants, and depart with a wheelbarrow of loot before the first rabbit emerged. "Balloons," Bill said. "Everyone trusts a man with balloons." Molly folded the map. It was almost too easy.
