Molly crouched behind the hedge, studying the bungalow as if it were a mint and not a house with balloon arches and a cardboard dragon taped to the door. Through the window, children in paper crowns swarmed around a mountain of presents. “Bill, this is either genius or the moment we admit we’ve lost all professional standards.” “Standards are for thieves with pensions,” Bill whispered, adjusting a tiny plastic tiara he’d found in the gutter. “Observe the weaknesses: one clown, two exhausted parents, and a piñata distracting the entire security team.” Molly unfolded a crayon-scribbled floor plan. It smelled faintly of jam. “We go in as entertainers, sweep the loot into the laundry basket, and exit during cake deployment.” “Bold. Elegant. Slightly sticky. I love it.” Inside the gate, a magician was already bombing. A rabbit had escaped and was eating crisps under a chair. “Change of plan,” Molly said. “Chaos has opened a window.” Bill peered over the hedge. “Literally. The kitchen window’s open.” They slipped across the lawn, keeping low behind a bouncy castle shaped like a pirate ship. “If anyone asks,” Molly murmured, “you’re Uncle Pete.” “I can’t be Uncle Pete. I look like a man banned from aquariums.” “Fine. You’re the balloon emergency technician.” Bill straightened. “At last, a title worthy of my talents.”
