The rented van idled behind a bouncy castle warehouse, headlights off, windows fogged with nervous breath. Molly tapped a laminated floor plan against the steering wheel while Bill squinted across the street at the Henderson house, where forty-two balloons bobbed along the porch like a plague of rainbows. Inside, a dozen children screamed the words to a song about a purple dinosaur. "Mountains of presents, one unlocked back door, and a clown who drinks." Molly grinned. Bill nodded gravely and unfolded the pillowcase he had brought as a sack. It was printed with cartoon ducks, which he considered an excellent disguise. He adjusted a fake mustache that slid downward the moment he exhaled. Molly handed him a cone-shaped party hat, slightly crushed, reading HAPPY BIRTHDAY in gold foil. He put it on with dignity. Across the street, the front door burst open. A sugar-crazed toddler sprinted onto the lawn waving a plastic sword, chased by a sobbing parent who was clearly losing. Bill watched the chaos with professional admiration. Somewhere, a balloon popped, and nobody flinched. Their plan had survived worse, though rarely this many toddlers. "Right," Bill said. "Let's go steal some Lego."
