"Right, Bill, listen closely. The party's at number twelve, Maple Lane. Forty kids, one bouncy castle, and a mountain of presents in the front room." "Forty kids? Molly, that's a lot of tiny witnesses." "They're five, Bill. Their testimony is mostly about dinosaurs." "What about the parents?" "Dad's on the drinks table. Mum's doing the cake. Nobody's watching the presents except that one clown." "The clown's terrifying." "Ignore the clown. We go in through the back gate during the musical chairs. Everyone's screaming, nobody hears a thing." "And the getaway?" "Your van. Parked behind the ice cream lorry." "Molly, I'm not hiding a stolen Lego castle under my seat again." "It's a Lego castle, Bill. Greatest crime of our generation." "Fine. What's my job?" "You carry the big boxes. I grab the bags with the bows." "Why do I always get the boxes?" "Because you're strong, and because the last one you tried to steal was a hamster."
