Molly and Bill crouched in the shadows of their beat-up van, binoculars trained on the garish backyard across the street. Balloons bobbed like drunken sentinels, and a bounce house loomed like a pink whale. The blueprint of the McSnooty mansion sprawled between them, marked with crayon scribbles. "Bill, it's perfect," Molly whispered, eyes gleaming. "Rich kid's fifth birthday. Presents stacked to the ceiling—Xboxen, bikes, gold-plated Legos. We hit at cake time, kids distracted." Bill mopped his brow, glancing at the piñata dangling like a candy-filled piñata of doom. "Kids, Molly? They're tiny landmines! One tantrum and we're swarmed. What if they bite?" She slapped the blueprint. "Disguises! You as the clown, me as the magician. I saw the rabbit out of the hat, you juggle the swag bags into our van." "Juggle? I can barely juggle my debts!" Bill yelped. "And the parents? Snooty types with tasers in their tutus." "Distraction: Fake fire in the bounce house. Chaos! We grab the gift table, bolt. Fifty grand resale, easy." Bill sighed, grinning despite himself. "Fine. But if a kid cries, you're the bad cop." Molly high-fived him. "Deal. Operation Candy Heist launches at three." The van rumbled to life, headlights off.
