"So we're clear," Molly said. "Bouncy castle at the rear, cake table by the patio doors." "And the presents?" "Living room. Stacked like a shrine." "How many kids?" "Eleven. Twelve if Dorian's cousin recovers from the chickenpox." "Eleven kids," Bill said. "Molly, I've done armored cars. I've done a diamond exchange in Antwerp. I have never done eleven eight-year-olds." "They're distracted. There's a magician." "A magician?" "Local man. Calls himself the Astonishing Reginald." "Is he astonishing?" "He pulls a rabbit out of a bag he keeps the rabbit in." "So we've got, what, four minutes of pigeon-based cover?" "Six. He does a long thing with a rope." Bill exhaled. "And the parents?" "Kitchen. Prosecco. They stop counting children at glass two." "What am I wearing?" "Nothing suspicious. Cargo shorts. Sun hat. Look like an uncle." "I don't look like an uncle." "Bill, you look like every uncle. You look like the concept of uncle." "And you?" "Face paint. I'm doing butterflies." "You can't paint." "I can paint a butterfly on a child." "Then we're in and out with, what, thirty parcels?" "Thirty-one. And Bill?" "Yes?" "If a girl called Priya offers you a sausage roll, take it. She's the only one who's onto us."
