Bill peered through the scratched windshield of the surveillance van, nervously tapping his plastic walkie-talkie against the steering wheel. Across the street, brightly colored pinwheels spun along the manicured lawn of a sprawling suburban split-level. "Blueprints on the table, Bill. Timmy turns six at fourteen-hundred hours." "Timmy? Molly, the kid eats paste. Is this really the score we risked parole for?" Molly slammed a hand-drawn floor plan onto the cluttered dashboard, completely ignoring his anxiety. She circled the sunroom with a dried-out red marker. "Do not underestimate the paste-eaters. Intel says his grandmother flew in from Geneva." "Geneva, Ohio?" "Geneva, Switzerland, you idiot! The woman smells like offshore accounts and peppermint. Do you know what kind of equity is sitting in that sunroom?" "Legos?" "Collector-grade Star Wars, Bill. Plus three unactivated iPads, a bespoke pony voucher, and an envelope from Great-Uncle Sterling that is palpably thick with fifties." Bill adjusted his binoculars, wincing as he scanned the patio furniture and the massive pile of ribbon-tied boxes stacked beside the swing set. "Bespoke pony? How do you bespoke a pony? Can you embroider a horse?" "Focus! The perimeter is crawling with hostiles." "You mean mothers?" "I mean aggressively caffeinated suburbanites with Ring cameras and zero carb tolerance. Here is the operational sequence. Phase one: the bounce house distraction." "I hate the bounce house, Molly. The static ruins my hair." "You won't be jumping. You will sever the blower motor cable at fourteen-fifteen precisely. When the castle deflates, toddlers panic, Brenda drops her pinot grigio, and chaos erupts. In the ensuing pandemonium, I breach the French doors." "Disguised as what, exactly?" "A gluten-free caterer looking for the recycling bin. I sweep the payload into the extraction sacks and exfiltrate through the hydrangeas." Molly leaned forward, her eyes narrowing as she adjusted her dark ski cap in the rearview mirror. "Wait, won't burlap look suspicious next to the unicorn balloons?" "Fine, the designer canvas totes. But you must hold the getaway vehicle at the curb." "The minivan?" "The tactical Pacifica, yes. Keep the engine idling and the child-locks disengaged. Watch for Captain Barnacles." "The clown?" "The clown has dead eyes and balloon-shaping hands that could crush a windpipe. If he twitches, you honk twice." Bill looked genuinely terrified, pulling a crumpled paper napkin from his jacket pocket to dab his forehead. "What happens if the ice cream truck cuts me off?" "You ram it." "Ram Mister Softee? That is bad karma, Molly!" "You want the score or not? This is unchecked bourgeois consumerism, ripe for the taking. We hit them where it hurts: their unearned childhood wonder." Molly checked the heavy brass padlock on her duffel bag before checking the rearview mirror one final time. "Do you think there’ll be cake?" "No cake! We are professionals, Bill. We do not compromise an op for buttercream." "What if it has cream cheese frosting?" "If you touch the red velvet, I leave you in the ball pit. Synchronize your Timex. Four minutes." Bill reluctantly reached for the ignition keys, his sweating knuckles whitening against the vinyl steering wheel. "May God have mercy on Timmy."
