Molly spread the napkin across the diner table and smoothed it flat with the side of her hand. "That's the house," she said, tapping a ketchup smear. "That's the bouncy castle. That's the gift table." Bill leaned in. "Why's the gift table bigger than the house?" "Because it's the objective, Bill. In a plan, the objective is always bigger." "It's a napkin." "It's a blueprint." "It's got a bit of egg on it." Molly slid her coffee cup onto the egg. "The party starts at two. Twenty-two children, one clown, and a woman called Deborah who I'm told runs the neighborhood watch group and cries at balloon animals." "So we go in at two." "We go in at two-forty. Cake time. Nobody watches the presents during cake. Cake is a religious experience for a seven-year-old." Bill nodded slowly, then stopped nodding. "How do we get past twenty-two children?" "We don't get past them. We join them." "Molly." "Hear me out." "Molly, I'm six foot four." "You'll be the entertainment. Nobody questions the entertainment. The entertainment arrives, the entertainment is fed, the entertainment is never described accurately to police." "What kind of entertainment?" "Magician." "I don't know any magic." "You know that thing with the coin behind the ear." "That's not magic, that's hygiene." Molly reached into her bag and dropped a crumpled purple cape onto the table. "You're Bilbolino the Astonishing. Forty-five minutes, no refunds." Bill picked up the cape with two fingers. "It smells like a wet dog." "It smells like showbusiness. Now, while you're astonishing them, I'll be Deborah's new best friend. Deborah has the keys to the side gate. Deborah also has a bad hip, which means Deborah sits down a lot, which means Deborah puts her handbag on the floor." "And the presents?" "Bin bags. Two of them, in the recycling bin by the shed. I load them during your finale." "What's my finale?" "You tell me. You're Bilbolino." Bill thought about it. "I could saw a child in half." "Absolutely not." "You said finale." "I said finale, not felony." Molly took a long sip of coffee. "You pull a scarf out of your sleeve, you bow, you take a slice of cake, and you walk out the front door at three-oh-five. Slowly. Magicians never run. It ruins the mystique." "And if someone notices the presents are gone?" "Then they'll notice at four, when the parents come back and everyone blames each other. That's the beauty of a children's party, Bill. It's already chaos. We're just adding one small piece of chaos to a very large pile of existing chaos." Bill folded the cape into his lap. "It's a birthday, Molly. There's a kid." "The kid gets thirty presents. The kid will not miss twenty-nine." "Twenty-nine?" Molly shrugged and looked out the window. "We leave the big one with the bow. I'm not an animal." Bill smiled. "Bilbolino wouldn't allow it." "No," she agreed, pocketing the napkin. "Bilbolino has standards."
