Model response

Molly peered through the bakery window at the church hall, where balloons bobbed like nervous witnesses and a clown unloaded wrapped boxes onto a trestle table. “Bill, tell me that’s not the easiest score in London.” “It’s a children’s party,” Bill whispered. “I feel morally complicated and professionally excited.” “Focus. Presents in, presents out, no one cries except possibly the clown.” “I hate clowns. They’re like burglars who gave up and joined theatre.” Molly unfolded a crayon-scribbled map. “Entrance at the bouncy castle. Diversion near the punch bowl. Extraction through the side gate beside the inflatable pirate.” “Did you just say extraction?” “Yes. Makes theft sound healthy.” Bill adjusted his tiny paper party hat. “And my disguise?” “You’re a divorced magician.” “That’s painfully specific.” “It explains the sadness.” Inside, children shrieked as a woman in a tiara lit candles on a dinosaur cake. Bill swallowed. “What if they spot us?” “They’re six. If you produce a coin from someone’s ear, they’ll appoint you mayor.” “And you?” “Nervous aunt. Strong opinions on napkins.” Bill nodded toward the gift table. “There must be thirty presents.” “Thirty hostages,” Molly corrected. “Now smile.” Bill inhaled. “Right. We go in, charm the room, liberate the loot, and vanish before ‘Happy Birthday.’” Molly grinned. “Exactly. Crime, but festive.”
