Molly adjusted her oversized clown wig and grinned at Bill, who was struggling into a polka-dot onesie two sizes too small. “This is the dumbest plan we’ve ever had,” she whispered. “We’re not even dressed as the right clowns. We look like rejected birthday mascots.” Bill zipped the suit with difficulty. “That’s the genius, Mol. Nobody suspects the ugly clowns. Kids are distracted by cake, parents by wine. We slip in, swap the presents for these identical empty boxes, and waltz out rich. Easy.” “Easy? There’s a bouncy castle, Bill. A bouncy castle. One wrong move and we’re both bouncing straight into a police car.” Molly checked her fake mustache in a compact mirror. “And why do I have to be the mime? I hate mimes.” “Because you’re naturally quiet when you’re stealing,” Bill said, adjusting his squeaky red nose. “Plus, if things go south, you can pretend you’re trapped in an invisible box while I run.” Molly rolled her eyes. “If I’m trapped in a box, you’re trapped with me, partner. We go in together, we bounce out together. Got it?” “Fine. But if a kid asks for a balloon animal, I’m throwing you under the bus.”
