Molly leaned against the rusted bike rack behind the community center, squinting at the blueprints spread across the hood of their getaway van. "Okay, Bill. Walk me through it one more time." Bill adjusted his fake mustache, which had slipped sideways during the drive. "Simple. We slip in during the birthday party. Seven-year-olds are distracted. Nobody notices two grown adults in clown costumes." "We're not wearing clown costumes." "We're wearing clown-adjacent costumes. That's close enough." He tapped a sketch of the room. "The presents are stacked by the piƱata. Forty-two gifts, Molly. Forty-two." "And the security?" "A retired crossing guard named Doris. She's sitting by the punch bowl." Molly groaned. "Bill, Doris once stopped a bank robbery by yelling at a man for jaywalking." "That was a rumor." "It was in the newspaper." Bill waved a hand dismissively. "Newspapers exaggerate. Anyway, I've already got a plan for Doris. Cupcakes. Lots of cupcakes. Nobody has ever left a frosting trap unattended." "Please tell me you didn't bake them yourself." "I bought them from the grocery store. I'm not a monster." Molly pulled a stack of wrapping paper from the van and held it up. "And what's this for?" "Disguise. If we carry the loot out in wrapping paper, we look like guests running late with gifts." "Bill, we're stealing the gifts. We can't wrap them to look like gifts we're stealing." He paused, considering this. "Okay, that's a flaw. But the bows are cute." She sighed and crouched to peer through the back window of the community center. Inside, a rainbow banner read HAPPY 7TH, MAX! and a bouncy castle sagged in the corner. "Look at that, though. There's a kid in a dinosaur costume crying because his balloon popped." Bill frowned. "That's sad." "It's heartbreaking. Maybe we skip the presents this time." "Molly, we've come too far. We've bought the van, the fake mustaches, and three bags of cupcakes." "Those cupcakes are for the kids, right?" "Mostly." She stood up and brushed off her knees. "Fine. But if Doris catches us, you're doing the talking." "Deal." Bill grabbed a sack from the back of the van and grinned. "Forty-two presents, partner. Let's go be the most unforgettable party crashers this town has ever seen." Molly grabbed her own bag, muttering, "Nobody ever said crime was this complicated."
