The van idled behind the bouncy castle hire depot, headlights off, its occupants wearing clown wigs they had swiped from a ribbon-cutting ceremony. Molly tapped the blueprints spread across the dashboard. "Third window on the left is the loose one," she whispered. Bill squinted at the sketch, which was mostly a cartoon unicorn with a question mark floating above its head. "And the guard?" "Mrs. Pennywhistle. Sixty-four. Runs the bran muffin stall." Bill nodded gravely and cracked his knuckles, producing a sound like a tiny cereal box popping. Across the car park, the party glowed with fairy lights. Toddlers wobbled past clutching balloons shaped like dinosaurs, and somewhere inside, a birthday cake the size of a tractor tire waited for its candles. Molly checked her watch. "Forty minutes until cake. Then the piñata breaks and every gift gets tossed onto the lawn." Bill grinned and adjusted his fake mustache, which had begun drooping like a wilted lettuce. "So we move during the piñata. Nobody watches the gift table when there's candy flying." They climbed out, moving as silently as ninjas in sneakers that squeaked on every step. Molly stopped and glared at him. "Bill, why are your shoes flashing red?" "They're stealth sneakers," he hissed. "The lights are a distraction."
