The getaway van smelled like cheese puffs and bad decisions. Molly sat behind the wheel, squinting across the street at a backyard full of bobbing balloons and a banner that read HAPPY SEVENTH, MAX! Bill spread a map across the dashboard. It had been drawn on the back of a pizza box. A rainbow wig sat in his lap like a dozing cat. "Phase one," he whispered. "I go in as the party clown." "You're going in as a clown?" "I've been practicing. My clown name is Sprinkles." "That's the worst clown name I've ever heard." "Sprinkles is a very dangerous name, Molly. Nobody suspects a Sprinkles." "Fine. Phase two?" "We grab the gifts from the gazebo before the cake comes out. Then we deal with the bouncy castle." "What's wrong with the bouncy castle?" "Hazel." "Who's Hazel?" "Six years old. Juice box in one hand, whistle in the other. Her job is watching the presents." "Can't we bribe her?" "I already tried. I offered her a Rocket Pop." "What did she say?" "She said she's allergic to rockets." "Bill, we're robbing a six-year-old." "We're relieving her of responsibility. Children are very stressed." "And Grandma?" "Grandma Dot has a whistle too. We'll need earplugs." "Do we have earplugs?" "We have cotton balls. That's basically earplugs if you're brave." "We're going to need a better plan." "We have a better plan. We have the ice cream truck." Molly glanced at the van's side, where a cartoon cone grinned beside a painted cow. Not exactly subtle. "This isn't an ice cream truck, Bill. It's a van with a jingle button." "Exactly. Nobody suspects an ice cream truck. Everybody chases one." "Have you ever actually seen anyone chase one?" "I tested it outside the library." "And?" "Two toddlers and a librarian. Today we'll get a dozen kids. They'll sprint toward us, and we'll be gone before they realize we're not selling Rocket Pops." "So I'm the ice cream man?" "You're the ice cream man, Molly. You have the face for it. Trustworthy. A little sad." "Thanks. Do I get a hat?" "You get a cone hat." "And bring the wheelbarrow." "Why do we need a wheelbarrow?" "Some of those boxes are the size of a fridge." "What's in them, a refrigerator?" "Mostly dinosaurs. Also a remote-control shark." "I want the shark." "Nobody gets the shark, Molly. The shark is a menace." Molly sighed. "Do you feel bad about this?" "Not even a little. I'm a professional." "Bill, your lip is trembling." Bill dabbed white greasepaint onto his cheeks with a shaking finger. "It's the greasepaint, Molly. It's very stiff." "Showtime, Sprinkles." Molly hit the jingle button. The tune tinkled down the street, and within seconds a dozen kids dropped their juice boxes and sprinted toward the van. Hazel abandoned her post. Only Grandma Dot stayed put, whistle between her teeth, eyes narrowed. "Remind me again why we don't have normal jobs?" Molly asked. "Nobody hires a Sprinkles," Bill said, and slipped out of the van.
