The warehouse smelled of stale popcorn and cardboard, remnants of some forgotten carnival. Molly spread the blueprints across an overturned crate, tracing her finger along the dotted line that marked the perimeter of the Hendricks estate. Bill leaned over her shoulder, chewing on a toothpick like it owed him money. "Ten kids," Molly said. "One bouncy castle, three clowns, and a security guard who's probably more interested in the cake than us." Bill grunted. "Cake's the real threat. Man, I love cake." She rolled her eyes and continued mapping their route—through the hedge maze, past the pony rides, straight to the gift table stacked high with wrapped boxes worth more than most banks they'd hit. The plan was elegant in its absurdity: two grown adults dressed as party clowns, sneaking presents into oversized balloon animals. "You sure about the clown costumes?" Bill asked, already looking queasy. "You wanted the pony costume instead?" He shuddered, and that settled it. Molly rolled up the blueprints, tucking them beneath her arm like a general preparing for battle. Outside, the sun dipped low, painting the sky in shades of orange and gold—perfect timing for a party crash. "Let's go steal some birthdays," she said, smirking as she slung her bag over her shoulder.
