Molly tapped the blueprint of the Henderson mansion. "The party starts at three. Every kid will be in the ballroom by then, and the presents will be stacked by the piano." Bill squinted at the sketch, a half-eaten cookie in his fist. "Why do we need a disguise? Can't we just walk in?" "Because you're wearing a clown nose, Bill. That's a disguise." "It's a party, Molly. Clowns are expected." She sighed and pulled a fake mustache from her coat. "Fine. You're the magician's assistant. I'm the uncle who forgot the birthday girl's name." "What if someone asks for my rabbit trick?" "You don't have a rabbit." "I have a rabbit, Molly. Mr. Whiskers. He's in the van." She pinched the bridge of her nose. "Bill, we are not bringing a rabbit into a heist." "He's very quiet. Mostly." Molly grabbed the gift bags they'd sewn from old curtains. "Just stick to the plan. In, out, no one cries." "No promises," Bill muttered, sliding the cookie into his pocket.
