The getaway van idled behind a row of wilted hedges, headlights off for maximum sneakiness. Molly crouched by the bumper, peering through binoculars at the bouncy castle glowing in the backyard of number 14 Maple Drive. Balloons bobbed. Somewhere, a clown was shrieking the rules of musical chairs. Beside her, Bill adjusted his ski mask, which had been designed for a much smaller man. He patted his coat pocket, where a crowbar and a sack of jelly beans clinked together. "Is the security really a golden retriever?" he whispered. "Bribe him with a sausage roll." Bill sighed. Across the lawn, a parent in a sensible cardigan waved at the empty street. Molly waved back, then tugged his sleeve. Together they slipped through the side gate, past a mountain of scooters and a sign reading "Shoes Off, Please!" Bill removed his boots with dignity. Molly did not. The back door was unlocked, because of course it was. Inside, presents towered on a folding table, wrapped in paper covered with dinosaurs and sparkly unicorns. Molly rubbed her gloved hands together. "Grab the big ones." Bill was already stuffing a pony-shaped box into his sack. He stared at the label, then at Molly. "Molly, this one's a bicycle."
