Molly crouched behind the hedge in a black beanie and a grin that had done time in three counties. Beyond the garden fence, balloons bobbed like cheerful sentries over a children’s party, and the smell of cake drifted out every time the patio door opened. Bill adjusted his gloves and peered through the slats. “That’s a lot of wrapping paper,” he whispered. “And a lot of trust,” Molly said. Inside, children shrieked around a magician whose rabbit seemed to have given up on magic entirely. A mountain of presents glowed beneath a paper banner reading HAPPY BIRTHDAY, BEN. Bill swallowed. “We’re really stealing from children?” Molly checked her watch with professional dignity. “We’re liberating gifts from an inefficient distribution system.” Bill frowned at the lopsided piles. “What’s the plan?” Molly produced a hand-drawn map, two lollipops, and a tiny trolley. “You distract the clown,” she said, “I’ll handle the loot.” “There’s a clown?” “Apparently.” A cheer rose as someone outside popped a party popper, and the whole yard flashed with confetti. Molly pulled a face. “Perfect timing.” Bill straightened his tie, which he wore only for jobs this morally questionable. “If this goes wrong,” he muttered, “we were never here.” Molly smiled. “Bill, that’s the spirit of family fun.”
