Molly spread the blueprint across the kitchen table, smoothing the wrinkles with the flat of her hand. "Behold," she said. "The Hendersons' backyard. Site of tomorrow's score." Bill leaned over, squinting. "This is drawn on a napkin." "It's a very detailed napkin." "There's a coffee stain right where you've marked the entrance." "That's not a stain, that's the bouncy castle." Molly tapped it proudly. "Our point of ingress. We come over the back fence at exactly two o'clock, while the kids are distracted by the magician." Bill folded his arms. "And what makes you so sure there's a magician?" "Because it's Timmy Henderson's eighth birthday, and I read the flyer his mother posted in the grocery store. Balloon animals, face painting, and a magician named the Great Zambino." "You did reconnaissance at a grocery store?" "I did reconnaissance everywhere, Bill. That's what separates professionals from amateurs." He picked up the napkin and held it to the light, as if expecting hidden ink. "Let me make sure I understand the plan. We, two grown adults, are going to crash a child's birthday party to steal a pile of presents." "Not a pile. The pile. Do you know what kids get these days? Tablets. Gaming consoles. Gift cards stuffed inside little envelopes shaped like dinosaurs." "And the parents?" "Will be too busy filming everything for social media to notice two caterers slipping out the side gate with a duffel bag." Bill set the napkin down slowly. "We're caterers now." "We're whatever the situation demands." She slid a paper plate across the table. "I made us disposable name tags. You're 'Chad, Catering Associate.' I'm 'Brenda, Team Lead.'" "Why do you get to be Team Lead?" "Because I drew the napkin." Bill rubbed his temples. "Molly, the last time we improvised a disguise, you ended up handcuffed to a vending machine." "That was different. That was a bank. This is a backyard full of seven-year-olds high on sheet cake. Where's the danger?" "The danger," Bill said, "is that one of those seven-year-olds bites my ankle and I get tetanus." "Wear thick socks." He stared at her for a long, defeated moment. "And the getaway?" "My nephew's ice cream truck. Idling out front. Nobody questions an ice cream truck near a kids' party. It's practically camouflage." "Your nephew agreed to this?" "My nephew thinks we're delivering ice cream." Bill exhaled through his nose, the sound of a man watching his life choices parade past him. "So to summarize. We dress as caterers, infiltrate a magic show, steal a duffel bag of dinosaur envelopes, and escape in a stolen ice cream truck driven by an unwitting relative." "Borrowed ice cream truck," Molly corrected. "And yes. Flawless, isn't it?" "It is the single worst plan I have ever heard." "But?" Bill picked up the name tag, peeled the backing, and stuck it crookedly to his chest. "But I haven't got rent." Molly grinned. "Welcome aboard, Chad." "I hate you, Brenda."
