"Right," said Molly, unrolling the map. "Timmy Pembrook's seventh birthday. Forty guests, forty presents, one bouncy castle." "Why's the castle circled?" "That's our escape route, Bill." "We're escaping on a bouncy castle?" "Through it. Nobody searches a bouncy castle. Too undignified." "What about the clown?" "The clown is you." "I'm not doing the clown again. Last time a toddler bit me." "He was teething. It wasn't personal." "It felt personal. What's your disguise?" "Magician. While everyone watches me pull a rabbit out of a hat, you pull the presents into a sack." "Do you have a rabbit?" "I have a guinea pig named Gerald. Same energy." "And the mums? Party mums are terrifying, Molly. They notice everything." "Which is why I've hired a decoy. Ice cream van, parked out front, playing Greensleeves on a loop." "Genius. Pure genius. What if Timmy recognises us?" "He's seven. He thinks his dad is a pirate." "Is his dad a pirate?" "Accountant. Stay focused." "And the getaway?" "Party bags, Bill. We leave with party bags like everyone else." Bill cracked his knuckles. "One question. Do we have to sing Happy Birthday?" "Obviously. Bill, we're professionals. We sing it beautifully, then we rob him blind."
