Molly crouched behind the hedge, studying the bungalow’s defenses: pastel balloons, a rented bouncy castle, and a plastic dragon wearing a policeman’s helmet. Inside, shrieking children orbited a mountain of brightly wrapped presents beneath a banner reading HAPPY SIXTH, NATHAN. Bill adjusted his black ski mask, which had eyeholes cut at wildly different heights. “This is beneath us.” “It’s beneath everyone,” Molly whispered. “That’s why nobody looks down.” A clown staggered across the lawn carrying a tray of juice boxes. His oversized shoes squeaked with every step, announcing him like a guilty duck. Molly watched him vanish through the patio doors. The plan had been elegant until Bill’s van acquired a flat tire beside a petting zoo. Now their escape vehicle smelled permanently of goat and disappointment. Molly unfolded a hand-drawn map. The presents were marked with an X, though Bill had also marked the cake, the karaoke machine, and something labeled “possible treasure chest.” “That’s the piñata,” she said. “Could contain jewels.” “Could contain dental bills.” From inside came the thump of tiny feet and a chorus of children demanding music. Molly slipped toward the gate, Bill behind her with an empty laundry sack. A little girl spotted them immediately. “Are you magicians?” Bill froze. Molly smiled. “We specialize in making presents disappear.” The girl clapped. “Do mine first!”
