"Right," said Molly. "The birthday boy's name is Terrance. He's turning seven." "Seven," Bill repeated. "Molly, we did the Antwerp diamond exchange." "And now we're doing Terrance." "Why?" "Because his father is a hedge fund manager who buys apologies instead of raising him. Do you know what's in that living room? A Nintendo Switch. Three of them. A remote-control helicopter that costs more than my car." "Your car is a 1994 Corolla." "Which is precisely my point." Bill sighed. "How do we get in?" "You're the entertainment." "Absolutely not." "There's a costume in the boot." "Molly." "It's a bear." "What kind of bear?" "The friendly kind. Vaguely. One eye is somewhat wrong." "And what are you doing while I'm being mauled by seven-year-olds?" "Balloons. Nobody watches the balloon lady. It's the perfect cover. I'll stage them by the patio door, you keep the little monsters distracted, and by four o'clock we're eating cake in a Travelodge." "And if a child asks me for a hug?" "Then you hug the child, Bill. You're a bear. Bears hug." "Bears maul." "Not this one. This one has a job to do." Bill stared at the house. "I want half the helicopter."
