The warehouse was cold enough to preserve a side of beef, appropriate as Molly and Bill were robbing a nursery. Bill sat on a crate, sharpening a crowbar in a full clown suit complete with oversized shoes and a honking red nose. Makeup was smeared. Molly hovered over a blueprint of Henderson community center, tracing the route from kitchen to the gift table marked with X's. She wore a tactical vest covered in Velcro patches that screamed desperation. Papers littered the table between them, evidence of three hours of planning. The air smelled of regret. "You're overthinking it," Bill said. "It's a seven-year-old's birthday party, Molly. Not the Federal Reserve." "The kid has the Nintendo Switch under that table," Molly said. "Do you know what that's worth? Three hundred dollars. Plus gift cards." "Gift cards to where? Build-A-Bear?" "Exactly. We liquidate. I have a fence who takes glitter and LEGO." She looked up, eyes gleaming with the fervor of a general planning a coup. The blueprint showed the gift table marked in red, surrounded by stick figures like hostages. "Think about it. Wealth redistribution. From the haves to the have-nots. Namely, us." Bill stood up, cracking his neck. The clown suit had seen better days, the polka dots faded. He adjusted his askew collar. "I don't know, Molly. Last time we hit a daycare, a dog chased us and a woman swung a diaper bag like a flail." "That was different. That was a daycare," Molly said. "This is a party. There will be cake. I've calculated the sugar crash window." Molly produced a grappling hook from her belt, twirling it with surprising dexterity. It was painted pink. "I'll rappel through the bathroom window. You create a diversion in the main hall." "With what? My dance routine?" "Better. I bought these." She held up three neon-green hats. "The propellers trigger trance states in developing brains. Basic psychology." "You're going to rob children while wearing a tactical vest?" "I'm going to rob children while wearing a tactical vest," Molly said. "There's a difference between amateur hour and professional larceny. The vest says 'I mean business,' even if my business is Paw Patrol theft." She loaded the hook into a shoulder holster. Her belt held the lock picks, a flashlight, and a granola bar for emergencies. She checked her watch, a digital behemoth that looked NASA-issued. "We move at 2:15. The pinata drops at 2:30. The toddlers will be too busy hitting a donkey to notice a woman in camouflage crawling toward the gifts." Outside, their minivan idled, exhaust dripping onto the asphalt. "And the parents?" "Drunk on boxed wine and regret. Sangria from a crockpot." Bill nodded, adjusting his clown wig that defied gravity and good taste. "We're really doing this," Bill whispered. "Most people are planning retirements. We plan to crush third-graders' dreams." "Not crush," Molly said. "Redistribute. 'The Case of the Missing Switch.' It has a noir ring." "It has a lawsuit ring," Bill muttered, smiling.
