Molly leaned over the sticky kitchen table, unfolding a crumpled floor plan. "Okay, Bill. The Henderson birthday party starts at three. Eight kids, two parents, one very large dog named Biscuit." Bill scratched his chin with a plastic fork he'd found in his coat pocket. "I don't like dogs, Molly. Dogs have opinions." "Biscuit is asleep by the fireplace. We check that first. Then we go in through the side door while the magician is doing his rabbit trick." "Why do magicians always have rabbits? Nobody's ever pulled a sensible animal out of a hat. Where's the goose? Where's the cat that pays taxes?" "Focus, Bill. The presents are stacked in the living room, under the big tinsel tree. I counted twenty-three boxes." "Twenty-three! That's a lot of loot. What if one of them is just socks? I'm not risking my back for socks." "We open one first to check. Quality control. Plus, I saw a box shaped like a pony yesterday." "A pony? You can't fit a pony in my van, Molly." "It's a toy pony, Bill. A plastic one. Honestly, your brain is a bag of marbles rolling downhill." Bill nodded seriously. "Fair. What's our cover?" "We're the entertainment. I told the mother we're the clown company she booked last month." "We don't have clown costumes." "I have two red noses and a bicycle horn. That's basically a costume." "Molly, you can't be a clown with a horn. Clowns need big shoes. I'm not walking around in shoes that make me look like a duck." "Then you're the duck, and I'm the clown. Nobody questions a duck at a party." Bill sighed and pulled a pair of enormous yellow shoes from under the table. "Fine. But if Biscuit wakes up, you're handling him. You're the one with the dog treats." "I don't have dog treats." "Then what's in that Ziploc bag?" Molly froze, then slowly lifted the bag. Inside were a dozen glazed donuts. "Those are for the parents. Bribery is a crucial part of any heist." "Okay, fine. Donuts it is," Bill said, grabbing one. "Let's go steal some presents." "Remember, nobody gets hurt," Molly said, adjusting her red nose. "And nobody sings Happy Birthday." "Deal," Bill said. "Though if they make us sing, I'm going full duck."
