"Bouncy castle," Bill said. "That's our way in." "You want to enter through a bouncy castle." "Nobody suspects a man emerging from a bouncy castle. It's the perfect blind spot." "Bill, you're forty-six." "I'm spry." "You threw your back out opening a yogurt." "That yogurt was defective." He unrolled a napkin covered in crayon. "Right. Presents go on the trestle table, here, by the piƱata. Twenty-two guests, twenty-two gift bags, plus the big stuff from the grandparents." "And the parents?" "Distracted. There's a magician at two. Name's Mister Wobbles." "Mister Wobbles." "I've met him. He's got a rabbit and a drinking problem, and for sixty quid he'll do a ten-minute card trick nobody can follow." "You bribed the magician." "I *invested* in the magician." Molly tapped the napkin. "What's this circle?" "Dog." "There's a dog?" "Small one. Barks at strangers. That's why you're bringing sausages." "I'm not bringing sausages to a child's birthday party." "You're bringing sausages, I'm bringing the van, and we're out by half past with four hundred quid of Lego." "And the birthday boy?" Bill hesitated. "He'll learn something valuable about impermanence." "He's turning six." "Never too early," Bill said, folding the napkin. "Wear something with pockets."
