The van smelled faintly of greasepaint and desperation. Molly stared at the hand-drawn map taped to the dashboard while Bill adjusted his enormous red nose. "Okay, walk me through it again, Bill. We are stealing from a seven-year-old's birthday party?" He had glitter in his eyebrows and a laminated plan that said TIMMY'S PARTY in Comic Sans. It was not inspiring confidence. "Technically, we're stealing from eight seven-year-olds. It's a haul, Molly. Think of the Legos." Outside the suburban house, thirty screaming children bounced inside a castle. A banner reading seven today fluttered dangerously over a table piled high with wrapped boxes. "We used to steal diamonds, Bill. Blood diamonds. Now we're after Paw Patrol plushies?" Molly pinched the bridge of her nose. She had cased banks with fewer security cameras than this backyard. "Those plushies retail for forty bucks each. Plus there's cake. Free cake, Molly." Bill popped his lapels proudly. One squeaked. "I can't believe you put on a clown suit for this." The clown shoes were size twenty-two and each step sounded like a dying goose. Several dogs in the neighborhood had already started howling. "It's camouflage. Every kids' party has a sad clown. I am method acting." Molly looked at her own outfit, a sequined tuxedo jacket over sweatpants that she had found in the van. It was the magician uniform. "You look like a sad accountant who lost a fight with a balloon factory." "Exactly. So I walk in, yell surprise, grab the present mountain, and run." She imagined trying to explain this to their former fence, Viktor, who only dealt in uncut emeralds and stolen Picassos. "And what do I do? Juggle for the parents while you commit felony theft?" Bill was already stuffing rope and trash bags into his polka dot pants. His commitment to the bit was almost admirable. "Better. You're the magician. You make the presents disappear. Poof." "Oh, brilliant. Nothing suspicious about a magician stuffing a trampoline into her van." A child ran past the van window chasing a bubble. Molly softened for half a second, then remembered the kid had a Nintendo Switch box on the present table. "Relax, it's not even theft. It's aggressive birthday arbitrage." "Will there at least be goodie bags for the crew? For morale?" "Molly, if this works, we get goodie bags forever. And maybe a juice box." "Fine. But if I have to sing baby shark, you owe me fifty percent extra." "Deal. Now help me get these squeaky shoes on. Operation Pinata is a go." Molly sighed and pulled her top hat lower. Bill honked his own nose by accident and jumped. The heist was about to begin. "Operation Pinata? Seriously? We are the worst criminals in town." "Hey, worst criminals still get cake. Let's roll, partner." "If anyone asks, we were never here. We were stealing diamonds." "Too late. I already RSVP'd. Plus one magician." "You absolute clown, Bill." Somewhere inside, someone started playing Happy Birthday terribly off-key. Loudly and forever.
