“Molly, I’m saying the clown door is the weak point.” “Bill, it’s a bouncy castle, not a fortress.” “Exactly. No one guards a bouncy castle.” “Except thirty children with frosting in their hair and the reflexes of caffeinated squirrels.” “We mingle.” “You’re six foot four and wearing a trench coat full of empty gift bags.” “It’s called preparation.” “It’s called looking like a sad magician.” “Fine. You wear the trench coat.” “I’m not wearing the crime coat.” “Then distract them.” “How?” “Ask who wants cake.” “That starts a stampede.” “Perfect cover.” “No, perfect lawsuit.” They crouched behind the hedge, watching balloons bob above the garden fence. “Target list?” Molly whispered. “Princess box, dinosaur box, suspiciously heavy pirate box.” “The pirate box is probably socks.” “Treasure socks.” “Bill, these are children’s presents. We are already morally underground.” “Temporarily. We’ll donate the boring ones.” “That’s not how redemption works.” A shriek rose from the yard. “Piñata,” Bill said. “Our window.” “That’s not a window. That’s chaos with a stick.” “Same thing.” “New plan,” Molly said. “We ring the bell, apologize, and say we’re at the wrong party.” “And the presents?” “We steal the leftover cupcakes.” Bill paused. “Chocolate?” “With sprinkles.” “Madam, I’m in.”
