Molly spread the blueprints across the table, knocking over a juice box she'd stolen earlier for research purposes. "The bouncy castle is our entry point," she said, jabbing the paper. "Nobody suspects a person crawling through inflatable walls." Bill frowned. "And the security?" "One clown. Maybe two." "Clowns terrify me, Molly." "That's the genius of it. They terrify everyone." She grinned. "We strike during pin-the-tail-on-the-donkey. Total chaos. Blindfolded children swinging wildly." Bill scribbled notes. "What about the cake?" "What about it?" "Do we take the cake?" Molly stared at him. "We're stealing presents, Bill. Focus." "I'm just saying, that's a lot of frosting to leave behind." He looked wounded. "I haven't eaten since the bake sale job." "Fine. You handle dessert acquisition. I'll bag the gifts." "Deal." Bill extended a sticky hand. "What's our exit?" "The piƱata distraction. When it bursts, candy rains down, kids scramble, and we vanish through the ball pit." "The ball pit?" Bill paled. "Do you know what's in those things?" "Riches, Bill. Glory." Molly rolled up the blueprints triumphantly. "And probably a lost shoe." He sighed, pocketing his pen. "I really hope it's a chocolate cake." "It's a children's party. It's always chocolate."
