Molly slapped a crayon-drawn map onto the hood of the van. "Okay, Bill. Tyler Pemberton's sixth birthday. Thirty guests, one bouncy castle, and a mountain of presents in the den." Bill squinted at the paper. "Why is the den a purple dinosaur?" "That's not a dinosaur. That's the den. I got nervous and started doodling." "Right. And how do we get in?" "You're the clown. I'm the caterer. You distract the children, I fill the pizza warmer bag with presents, and we're gone before cake." "Nobody leaves before cake, Molly. It's the most suspicious thing you can do. Kids notice." "Fine. We leave after cake." "After cake they're on sugar. Six-year-olds on sugar are a SWAT team with no rules and no bedtime." "You've faced armed guards in Monaco, Bill." "Armed guards respect boundaries. A kid named Brayden bit me at my niece's party, and I still have the scar." He rolled up his sleeve and showed her. "That's a mosquito bite." "It's emotional, Molly." She sighed and tapped the map. "Focus. What's your clown name?" "Sir Giggles-a-Lot." "No. Too memorable." "Then Bobo." "Too generic. Parents will assume you're a professional." "I am a professional!" "A professional clown. Bill, you can't even do a balloon dog." "I can do a balloon dog. It just looks like a sad snake." "Right. So they'll think you're bad at your job, and nobody investigates a bad clown. It's perfect cover." Bill frowned. "That's insulting, but strategically sound." "Thank you. Now, the presents. Forty-two boxes, according to the invitation list. I calculated the pizza bag holds twelve." "So we need four trips?" "We need one trip and a lot of confidence. I've brought wrapping paper." "Why?" "We wrap your van in it. Then it's just a giant present. Nobody suspects a giant present." Bill stared at her. "Molly, that's the dumbest plan I've ever heard, and I once worked with a guy who tried to rob a bank using a trebuchet." "Did it work?" "He did get the vault door to look at him funny." "Then we're ahead of the curve." She grinned and pulled a rainbow wig from her bag. "Put this on." "Absolutely not." "Bill, there's a pony." He paused. "A real pony?" "Named Sparkle Tuesday." Bill snatched the wig and jammed it onto his head. "Fine. But if Brayden's there, I'm not turning my back on him." "Deal. Now remember the signal. If it goes wrong, say 'the cake is melting.'" "And if it goes really wrong?" "Say 'the cake is a lie.'" "That's a video game reference." "It's also true. I made the cake." Bill sighed, straightened his red nose, and opened the van door. "For the record, this is my worst heist." "You said that about the trebuchet." "That one had better snacks." Molly hoisted the pizza bag over her shoulder. "Then let's go steal some snacks too."
