Rain polished the alley, turning every puddle into a mirror. Molly adjusted her sparkly balaclava while Bill crouched beside a cupcake van. “The security is probably just Aunt Linda with a whistle,” Molly said. “Children are ruthless,” Bill whispered. “So are uncles guarding cheese platters.” Beyond the fence, balloons bobbed above the hall, and a banner announced TIMMY’S SEVENTH BIRTHDAY. Their target sat beneath a table, disguised as wrapping paper and optimism. “We enter through the clown door,” Molly said. “There’s a clown door?” “Every door becomes a clown door if you paint a smile on it.” “That sounds like vandalism.” “It sounds like architecture.” Bill produced two hairnets, a grappling hook, and a handwritten map labeled “Possible Bathrooms.” Molly inspected it, then pointed toward a side entrance guarded by a sleeping dachshund wearing a party hat. Its snore sounded alarmingly official. Both checked pockets carefully. “Once inside, we grab the largest boxes,” Bill said. “No,” Molly replied. “We grab the presents children actually want, leaving socks and educational games.” “You have a conscience?” “I have standards.” “Fine. But if there’s cake, the operation changes.” “We steal cake too, obviously, if guards permit.” “And split it fairly afterward.”
