The warehouse smelled like stale popcorn and desperation, which Bill thought was fitting given their current career trajectory. He spread the blueprints across a card table that wobbled with the enthusiasm of a drunk flamingo. "So we go in through the bounce castle," Bill said, tracing a route with his finger. Molly stared at him like he'd suggested they rob a bank using only mime skills. "Bill. It's a bounce castle. For six-year-olds." "Exactly! No one suspects the bounce castle." She rubbed her temples. This was their eleventh heist together, and somehow Bill's plans kept getting worse. Last month it was a bakery. The month before, a library, which had resulted in overdue fines that still haunted her credit score. "There's going to be clowns," Molly said. "Actual professional clowns, Bill." "I'm not scared of clowns." "You cried during that circus documentary." "That was about elephant rights!" Molly sighed, pulling out her own plans—considerably more detailed, color-coded, and free of inflatable structures. The presents were stacked near the cake table, guarded by nothing more than a distracted babysitter and a piñata shaped suspiciously like a police officer. "We go in as caterers," she said. "Simple. Dignified." Bill grinned. "Can I wear the mustache?" "No." "The little hat?" "We'll see."
