Molly slid the blueprint across the table, jabbing a finger at the crude drawing of a bounce house. "You want to rob a six-year-old's birthday party," Bill said flatly. "Not just any six-year-old," Molly said. "Timmy Fitzgerald. Grandson of a jewelry magnate. You know what kind of loot gets dropped at that party? We're talking wrapped boxes stuffed with cash, gift cards, maybe even a tablet or two." "Molly, there's gonna be clowns. Bouncy castles. Parents with pepper spray and mom-instincts." "Which is exactly why nobody suspects a thing. We dress as the entertainment. I'll be the balloon lady, you're the magician." Bill crossed his arms. "I don't do magic." "You don't need to be good, Bill. Just distracting. Pull a rabbit out of a hat while I load the presents into the van." "And if some kid notices his birthday loot walking out the door?" "Then you pull two rabbits out of the hat." Bill stared at her for a long moment, then sighed. "Fine. But I'm not wearing the sequined cape." "You're wearing the cape." "The cape makes me look ridiculous." "The cape makes you look magical, Bill. There's a difference." He grabbed the blueprint, grumbling. "This better be worth it." "Trust me," Molly grinned. "It's gonna be a blast."
