"Bouncy castle's the weak point," Bill said. "It's a children's party, Bill. There is no weak point. It's all weak point." "So we go in through the bouncy castle." "Why the bouncy castle?" "Nobody suspects a man emerging from a bouncy castle." "Because nobody's ever done it. Because it's a sealed inflatable object." "Then I'll be the first, Molly. Pioneers get remembered." "Pioneers get arrested with their trousers full of party bags." "The presents are stacked on the trestle table by the window. Forty, maybe fifty. Some of them are big." "How big?" "Trampoline big." "We're not stealing a trampoline." "I'm just saying, the intelligence suggests trampoline." "Who gave you the intelligence?" "My nephew. He's eight. He's got no reason to lie." "He's got every reason to lie, he's eight." "He wants a cut." "Of what?" "The presents." "So he's stealing his own birthday presents." "It's his cousin's party. There's bad blood." Molly rubbed her eyes. "Fine. Entry?" "Front door. I'll be a clown." "You can't do balloons." "I can do a sausage." "A clown who can only do sausages is a suspicious clown." "Then you distract them." "With what?" "Cake." "Whose cake?" "Theirs. We steal the cake first, then give it back. They'll love us." Molly stood. "Get the wig."
