Molly adjusted her fake glasses and leaned across the rickety diner table. “Okay, Bill, walk me through it again. We’re not robbing a bank, we’re robbing a six-year-old’s birthday party. The cake is our cover.” Bill rubbed his hands together, grinning like a kid who’d found the cookie jar. “Exactly, Mol. These little gremlins are loaded. Every spoiled brat in that room’s got a mountain of shiny wrapped boxes. We hit it right after they sing Happy Birthday, when the sugar rush kicks in and the adults start drinking.” Molly snorted. “You want us to blend in with a bunch of screaming kindergartners? I’m five-foot-two and I still look like I pay taxes.” “Relax. We’re the new entertainers. I’m Bouncy the Clown and you’re my lovely assistant, Sparkles the Magnificent. I’ve got the polka-dot suit in the trunk. You get the tutu.” “I am not wearing a tutu, Bill. I have dignity.” “Dignity don’t buy us a new fence for the haul. Think of the haul, Molly. Tiny bicycles, gaming consoles, those creepy dolls that cry real tears. We could clear ten grand easy on the secondary market.” Molly tapped her spoon against her coffee mug. “Security?” “Balloon arch and one very tired mom with a wine spritzer. The dad’s wearing a cone hat and looks ready to cry. We slip in during musical chairs. When the music stops, we start loading the gift table into the fake ambulance we rented.” “Ambulance? You said we had a van.” “Ambulance is funnier. If anyone asks, little Timmy ate too much frosting and we’re taking him for observation. Meanwhile we’re observing the value of his new drone.” Molly pinched the bridge of her nose. “Bill, this is the dumbest plan since the Great Grocery Cart Caper of ’09.” “That one almost worked.” “We stole a shopping cart full of frozen peas.” “Market value, baby. Focus. We go in at three-fifteen, right after the piñata bursts. Chaos is our friend. While the kids are fighting over Tootsie Rolls, we wheel the big red wagon out the back door. I’ve labeled it ‘Lost and Found.’ Genius, right?” Molly stared at him for a long moment. “You do realize these children will remember us forever. We’ll be the reason little Emily trusts no one wearing face paint after age thirty.” Bill shrugged. “They’ll get over it. Besides, we’re leaving them the cake. We’re not monsters.” “Speaking of monsters, what if the clown-phobic kid has a meltdown?” “Then you do the thing with the balloon animals. You’re surprisingly good at twisting those wiener dogs.” “I hate you.” “You love me. Admit it, the thought of stealing Barbie’s Dreamhouse while wearing a sparkly tutu gets your criminal heart racing.” Molly sighed, then slowly smiled. “Fine. But I pick the getaway music. And if we get caught, I’m telling the cops you made me do it.” Bill raised his coffee cup. “To the children’s party of the century. May their tears be brief and their presents plentiful.” Molly clinked her mug against his. “And may we never, ever speak of the tutu again.”
