"Right," said Molly. "The Fairbanks residence. Fourteen children, one bouncy castle, and forty-odd presents just sitting there in a pile." "I don't like it." "You said that about the pet shop." "And I was right. I still can't hear out of this ear because of that cockatoo." "Bill. There's no alarm. There's no dog. There's a woman named Deborah handing out slices of Colin the Caterpillar." "There's fourteen children." "Children are not a security system." "Children are the *ultimate* security system. They're small, they're everywhere, and they have no respect for the social contract. One of them bit my cousin at a christening. Straight through the trousers." "We'll be in and out in ninety seconds." "And how are we getting in?" "You'll be the entertainment. Clowns go unquestioned." "Absolutely not." "I've bought the wig." "Molly—" "It's ginger. It's very expressive." "What are you doing while I'm being *expressive*?" "Loading the van. You keep them occupied with balloon animals." "I can do a snake." "A snake is a balloon, Bill." "It's a very *convincing* snake." Molly sighed and folded the blueprint. "Fine. Do the snake. Just don't let Deborah near the gift table."
