The warehouse smelled like stale popcorn and desperation, which suited Molly just fine as she spread the blueprints across a folding table shaped suspiciously like a ping-pong table with delusions of grandeur. Bill leaned over her shoulder, chewing a piece of bubblegum he'd stolen from a toddler earlier that week, purely for practice. "So the target is a seven-year-old's birthday party," Molly said, tapping the paper. "Presents are stacked by the cake table. We go in disguised as clowns, grab the loot, and vanish before the pin the tail on the donkey game even starts." Bill frowned. "I don't do clown makeup. Makes my face itch." "You'll survive." "Last time I wore face paint, I broke out in hives shaped like Winnie the Pooh." Molly ignored him, already pulling balloons from a duffel bag stuffed with props. There were juggling pins, a unicycle with a wobbly wheel, and a red rubber nose that squeaked ominously every time she squeezed it. The plan was simple: blend in, entertain briefly, steal enormously. "Just remember," she said, tossing Bill a polka-dot vest, "no matter what happens in there, we do NOT eat the cake." Bill's eyes lit up with betrayal already forming. "But it's chocolate." "That's exactly why I said it, Bill."
