Molly spread the blueprint across the hood of the van and smoothed it flat with a gloved hand. Bill squinted at it. "This is a bouncy castle," he said. "It's the primary defensive structure," said Molly. "Molly, it has a slide." "The slide is the least of our problems. Tobias Pemberton-Hayes turns eight at two o'clock. Forty-one guests, thirty-eight presents, one clown." "Why is there a clown?" "His mother, Denise, booked him. Denise doesn't believe in refunds." "What's the clown's name?" "Giggles McPoot." Bill shuddered. "Of course it is. Fine. How do we get in?" "You're the face painter. I'm your assistant." "I can't paint faces." "Nobody can. You draw a butterfly on every cheek and call it a tiger. Kids are trusting." "That's the saddest thing you've ever said." Bill tapped the map. "Where are the presents?" "Folding table by the patio, guarded by Denise's mother, Grandma Ruth, who's ninety and carries a whistle." "A whistle?" "She was a lifeguard in 1961. She's never let it go." Bill sighed. "How do we distract her?" "Simple. At 2:30, you announce the pony has escaped." "There's a pony?" "There's no pony. That's the beauty. Every parent will run outside looking for it, and while they panic, I load the presents into the van." "Thirty-eight presents, Molly. You'll need a dolly." "I have a dolly. It's disguised as a wagon that says 'Birthday Boy Express.'" Bill blinked. "You've been busy." "I've been sleepless. There's a difference." She flipped the blueprint over. "Now, rules. We leave the cake." "Obviously. We're thieves, not animals." "And we don't take the goodie bags." "Even the ones with the little bubble wands?" "Especially those. It's a gray area." Bill nodded solemnly. "Do we have a code word?" "Cupcake." "Why cupcake?" "Because nobody suspects a cupcake." "Molly, Denise will be serving cupcakes." "Then it's a very unsuspicious word." He rubbed his temples. "What if the kids catch us?" "They won't. They'll be busy with Giggles McPoot." "What if Giggles catches us?" Molly paused. Somewhere far away, an ice cream truck jingled. "Then we do what professionals do," she said quietly. "We offer him a cut." "A clown with a cut. I hate this job." "You said that about the museum." "The museum had a guard who liked me. This has a ninety-year-old with a whistle." "Bill." Molly grabbed his shoulders. "Think of the payoff. Probably four LEGO sets, two remote-control cars, and a mystery box that could be anything." "It's a sweater," Bill said. "It's always a sweater." "Then we sell the sweater." He looked at the map, then at her, then at the little green face-paint kit on the dashboard. He picked up a brush. "Butterfly," he muttered. "Tiger. Butterfly." "That's the spirit," said Molly, and slid the van into gear.
