The van smelled like old pizza and worse decisions. Molly spread a hand-drawn map across the dashboard while Bill adjusted his ski mask, which he had put on backward. "Bill, you can't see." "I can see fine. I just see a lot of yarn." "Take it off. We're parked. Nobody's looking." He peeled it off, and his hair stood up like a startled cockatoo. Molly tapped the map with her pen. "Okay. Target is the Henderson house. Six-year-old named Tobias is having a dinosaur party. Twenty-two kids, fourteen parents, one clown." "Nobody said anything about a clown." "I'm saying it now." "Clowns are a dealbreaker, Molly. They're trained observers." "He makes balloon swords, Bill. He's not Interpol." Bill folded his arms. "Fine. Where are the presents?" "Living room, on a table shaped like a stegosaurus. Roughly forty gifts. We go in as the entertainment company's backup dinosaur." "We have a dinosaur costume?" "We have one dinosaur costume." "For two people." "Which is why you're the back half." Bill stared out the windshield. "I always end up the back half." "You have a gift for it. Once we're inside, I roar and distract the crowd, and you quietly swap the presents into these." She patted a duffel bag stamped with cartoon rockets. "What if a kid asks me something?" "You're the tail, Bill. Tails don't talk." "What if they pull me?" "Then you wag." Bill sighed and checked his watch. "What's the escape plan?" "Simple. Cake time. Everybody sings, the lights go off, we walk out the side gate." "And if it goes wrong?" "Then we're two adults in a dinosaur suit being chased by children. I like our odds. Toddlers have terrible cardio." "Some of them are six." "Six-year-olds are just toddlers with opinions." Bill nodded slowly, then hesitated. "Do we feel bad at all? About the kid?" Molly paused, pen hovering. "A little. So I bought him a dinosaur book. It's in the bag. We're leaving a receipt." "That's the most professional thing you've ever done." "Thank you. Now zip me in." Bill lifted the costume and squinted at the collar. "Molly, this has a tag. It says 'Property of Gary's Party Rentals. Fits ages nine to eleven.'" "We'll just be very confident." They wriggled inside. The zipper made a sound like a small animal giving up. Molly's view through the mesh mouth was mostly of the van's ceiling, and Bill's view was mostly of Molly. "Bill, stop breathing on my back." "It's a shared suit. Breathing is unavoidable." "Then breathe quieter." "How does one breathe quieter?" "Like a professional." Bill exhaled through his nose, whistling faintly, like a kettle with ambition. "Perfect," Molly muttered. "Let's go steal Christmas from a six-year-old." "It's his birthday." "Then let's go steal his birthday." The van door slid open, and the dinosaur waddled toward the balloons.
