The getaway van idled behind the bouncy castle hire shop, headlights off, its two occupants peering through the windscreen at the glowing garden lanterns of number twelve, Elm Crescent. Inside, forty children shrieked with delight while a clown with a sinister grin juggled flaming batons beside a cake shaped like a castle. Stacked on the patio sat a mountain of presents, each wrapped in paper so bright it practically glowed. "Ready?" whispered Molly, tugging a balaclava decorated with cartoon ducks over her ponytail. Bill nodded, hefting a crowbar wrapped in pink ribbon. He squinted at the front gate, where a plastic unicorn stood guard beside the doorbell. "Why is there a unicorn on the gate?" "Security," Molly said. "Nobody suspects a unicorn." Molly cracked her knuckles and slid open the side door. The night air smelled of sugar and panic. "Walk in, grab every bow, walk out." Bill followed her across the lawn, carefully avoiding the sprinklers and a small boy dressed as a dinosaur who kept staring at them with suspicion. Molly reached the patio, scooped up an armful of presents, and stuffed them into a sack labeled Santa's Overtime Bag. Bill tried the same, but his foot caught a rubber ball, sending him skidding across the grass like a penguin on ice. He landed face-first in a pile of crisps, a sparkly tiara stuck to his elbow. The party music cut out. Forty children gasped in unison. Molly grabbed Bill by the collar, hauled him upright, and sprinted for the van, the sack bouncing over her shoulder like a very determined reindeer.
