The blueprints were drawn on the back of a placemat from Dino's Pizza, which Bill considered a professional touch, since blueprints on printer paper looked amateur and blueprints on napkins fell apart when you sneezed. He had labeled the bounce house DANGER ZONE in red crayon, because it was the only writing implement in the van and because he felt the phrase carried appropriate gravity. Molly studied it with the expression of a woman being shown a child's macaroni portrait of herself. "Explain the clown," she said. "The clown is our way in." "You're going to be the clown." "I'm going to *be* the clown, Molly. There's a difference between wearing a costume and inhabiting a role." She looked at the wig on the dashboard, which had been purchased secondhand and smelled faintly of vinegar. Somewhere past the windshield, across two lanes of suburban asphalt and a hedge trimmed into the shape of a swan, the Pemberton residence was inflating. Nine children were expected. Nine children meant, by Bill's arithmetic, somewhere between eleven and twenty-two gifts, because there was always one overachiever whose mother brought a second present out of guilt. The presents would be stacked on a folding table beneath a banner that read HAPPY 7TH BIRTHDAY GRAYSON, and Grayson's father was, according to three weeks of patient surveillance, a man who put things down and forgot them, including his keys, his wallet, and once, memorably, his own child at a car wash. "Timeline," Molly said. "PiƱata at three-fifteen. Every adult in that yard turns to watch a blindfolded child swing a bat in a crowd. Nobody looks at anything else. Nobody *can*. It's the most dangerous four minutes in the American calendar." Bill tapped the placemat. "That's our window. You reverse the van up the side alley, I load the table into the laundry hamper, we're on the interstate before the candy hits the grass." "And the dog." "The dog," said Bill, "is handled." "With what?" "Rotisserie chicken." "You bought a rotisserie chicken." "I bought two. One for the dog and one for the drive home, and I want to be clear that if things go badly, the second chicken is still mine." Molly sat with this. She had worked with Bill for six years and had learned that arguing with him was like arguing with weather; you could describe it accurately and it changed nothing. She checked her watch, then the swan hedge, then the wig. "There's a flaw," she said. "There isn't." "Nine kids, Bill. Nine sets of parents. Twenty-something presents that all belong to a seven-year-old boy. Where exactly are we fencing four hundred dollars of dinosaur-themed merchandise?" Bill was quiet for a moment. Down the street, a bounce house shuddered upright like something being born. "That's phase two," he said. "There's no phase two. You've drawn a clown and a chicken." "There is *absolutely* a phase two, and it involves a flea market in Waukegan, and you will apologize to me by Tuesday." He picked up the wig, shook it out, and put it on with the solemnity of a knight lowering a visor. "Start the van, Molly. It's showtime."
