"Right, so the plan," Molly whispered, tapping the blueprint. "We go in through the chimney." "Molly, it's a bounce castle in the back garden." "Which is why we go in through the chimney of the bouncy castle. Obviously." "There's no chimney on a bouncy castle." "Then we improvise. Bill, focus. Forty-two presents, one clown, and a birthday cake shaped like a dinosaur." "I don't like the clown." "Nobody likes the clown. That's his job." "What if the kid wakes up?" "Then you hand him a balloon and say the magic word." "What's the magic word?" "Cake. Kids would sell their own mothers for cake." "Right. And the dog?" "The dog's been bribed with sausage rolls." "Molly, you bribed a dog with sausage rolls?" "Three of them. He's very reasonable. Now shh, I hear the piñata." "Who's holding the piñata?" "Nobody. That's the problem."
