"Right, so the bouncy castle's the weak point," said Molly. "The bouncy castle." "Structurally. We deflate it, the whole east lawn becomes a slip-and-slide of screaming children. Chaos. We walk out with the presents." "Molly, there's a clown." "Clowns can't run. It's the shoes." "His name's Bimbo the Magnificent and I've seen him at three birthdays now. He does a thing with doves." "Doves are a distraction, Bill. Doves are what he wants us looking at." "I'm just saying, a man who can produce four doves from a sleeve might have other tricks." "Are you frightened of the clown?" "I'm respectful of the clown." "The presents are stacked on a trestle table by the patio. Eleven of them, one enormous. Probably a trampoline." "We can't fence a trampoline." "We can bounce on a trampoline, Bill. That's the beauty. It's a heist with a retirement plan." "And the mother? Big woman, apron, wooden spoon?" "Deborah. She'll be inside with the cake." "You know her name." "I attended the planning meeting. Posed as a face painter." "You can't paint." "Nobody complained." "A child came out of there looking like a crime scene, Molly." "Tiger," said Molly. "It was clearly a tiger."
