Molly leaned over the sticky diner table and tapped the napkin map. "Okay. Pinkerton Street, number fourteen. Birthday party for a six-year-old named Tabitha. Forty presents, all wrapped in glitter paper." Bill squinted at the sketch. "Glitter paper? That's a crime in itself." "Focus, Bill. The gift table sits right beside the bouncy castle. We wait until the cake comes out, everyone runs to the frosting, and we walk straight in." "Walk straight in? Through the front door?" "Through the side gate. The one with the cartoon ducks on it." Bill frowned. "Why would a gate have ducks?" "Because it's a children's party, Bill. Everything has ducks." She slid a paper bag across the table. "Here's your disguise." He opened it and pulled out a yellow clown wig. "Absolutely not." "It's a clown's wig. Clowns are invisible at parties. Nobody looks at a clown. They're too busy screaming." "Molly, I am a grown man with a dignified face." "And a dignified face is exactly why nobody will suspect you." She tapped her own bag. "I've got a balloon animal kit and a fake magician's license." "You can't make balloon animals." "I can make a very convincing giraffe." Bill sighed and put the wig on anyway. It sat crooked over his ears. "How do I look?" "Like a clown who lost a fight with a hairdryer." She grinned. "Perfect." He leaned back, arms folded. "And when the kids notice their presents are missing?" "They won't notice. They'll be too busy fighting over the piƱata. Trust me, I've done this before." "You've robbed a children's party before?" "Two. The first one was a disaster. A boy named Oliver followed me for an hour asking questions about dinosaurs." "And the second?" Molly hesitated. "The second one was fine. Mostly." Bill groaned. "Mostly fine. Wonderful. What's our escape plan?" "We leave through the front door, carrying the presents openly, dressed as the party's hired entertainment." "That's not an escape plan. That's a confession." "It's a bold plan, Bill. Bold plans work." "Bold plans get us arrested." She stood, brushing crumbs off her coat. "Then we'd better be quick. Party starts in twenty minutes, and I want those glitter-wrapped boxes before the pass-the-parcel game begins." Bill adjusted his wig with a sigh. "Remind me why I agreed to this." "Because I promised you the good stuff. Rumor has it Tabitha's parents bought her a pony." "A pony? You didn't say anything about a pony." "I'm saying it now."
