"So it's a bouncy castle." "It's a bouncy castle, Molly." "You want us to breach a bouncy castle." "I want us to *utilize* a bouncy castle. There's a difference, and the difference is elegance." "Elegance. Bill. There will be a clown." "There will be a magician, actually, and I've already established rapport with him. His name is Doug and he owes eleven hundred pounds to a man called Terrance." "How do you know a magician who owes money to a man called Terrance?" "How do you not?" "And the presents?" "Conservatory. Stacked. Untouched, because Mrs. Pemberton has a rule: no opening until after cake." "After cake." "Which is at four, which gives us a fourteen-minute window during 'Pass the Parcel,' during which every adult in that house will be watching a seven-year-old lose their mind over a Kit Kat." "And if someone sees us?" "You're Auntie Kath. I'm Uncle Ray. We came for the christening and stayed for the divorce." "Whose divorce?" "Doesn't matter. Nobody asks. Nobody ever asks, Molly, that's the beautiful thing about families — everyone assumes someone else invited you." "Fourteen minutes." "Fourteen." "And the bouncy castle?" "Exit strategy." "Bill." "It deflates, Molly. It deflates *over the fence.*"
