The getaway van idled behind a bouncy castle warehouse, headlights off, engine humming like a nervous bee. Molly sat in the passenger seat, tapping a clipboard against her knee, while Bill squinted through binoculars at the party across the street. Pastel balloons bobbed above the garden fence. Somewhere inside, a clown was murdering a ukulele version of a birthday song. "Forty-two presents," Bill whispered. "Zero witnesses." Molly flipped a page on her clipboard, its corners already stained with frosting. Her plan involved a fake mustache, a stolen tray of cupcakes, and a magician who had no idea he was about to be distracted by her. "And no crumbs," she said. Bill lowered the binoculars and sighed. On their last heist, they had left a trail of sprinkles across three counties, and the police had followed it straight to their front door. Molly pulled on the mustache, which immediately slid sideways like a tired caterpillar. She pressed it harder and tried again, wincing as it stuck to her upper lip with a sound like tape ripping off a box. Bill reached into his coat, unwrapped a lollipop, and popped it into his mouth. "Relax," he said around the candy. "Nobody suspects two uncles with sticky hands." Molly adjusted her wig, checked the clock on the dashboard, and grinned. Operation Gift Grab was officially live.
