Bill unrolled the crinkled blueprint across the grease-stained hood of their dented getaway station wagon, using two half-empty soda cans to weigh down the curling edges. He adjusted his night-vision goggles, which were switched off to conserve battery power, and pointed a dramatically sharp yellow pencil directly toward the center. "Look at this perimeter. We have three inflatable bounce castles guarding the southern flank. High bounce frequency. Lethal impact if you mistime your descent." Molly rubbed the bridge of her nose, fighting an oncoming migraine beneath the flickering amber glow of a quiet, unlit suburban streetlight. She leaned down to inspect the master plan with open, undisguised disgust. "Bill, that is not a blueprint. That is an activity placemat from a diner, and those castles are drawn in purple crayon." "Tactical bouncy castles, Molly. Do not underestimate the terrain." "The target is turning six. He possesses the physical strength of warm pudding." Bill clicked his cheap ballpoint pen three times in rapid, militant succession, glaring across the warm hood as if addressing an insubordinate rookie operative. "He has eighteen cousins hopped up on blue raspberry punch. That makes them ferocious, feral, and utterly unpredictable. They bite, Molly." Molly tapped her fingers against the rusted metal, listening to the faint sound of nursery rhymes drifting over the cedar fence two houses down. She finally conceded the point with a heavy, reluctant sigh. "Fine, you made your point. What is the grand payload that makes this indignity worthwhile?" "The crown jewels. A remote-controlled monster truck, two motorized scooters, and an authentic imported robot that fires foam darts at supersonic speeds." "Supersonic?" "Twelve miles an hour. It stings bare flesh." Bill shrugged without the slightest shred of remorse. She reached deep into her heavy canvas satchel, double-checking the slender tension wrench and pick set before peering through the darkness toward the tall backyard gate. "What is the infiltration route?" "The doggie flap by the patio. I coat you in butter, push you through, and you disable the deadbolt." "I am not coating myself in dairy. We walk through the gate like professionals. When does the heist begin?" Bill checked the glowing green digital display of his tactical stopwatch, quietly tracking the sweeping second hand with intense, borderline unhinged concentration. "Fourteen-hundred hours. The hired clown starts making balloon animals, causing complete cognitive paralysis among the parents. That gives us four minutes to bag the presents." "And what about our getaway vehicle? Did you secure the van like I asked?" Bill puffed out his chest and gestured proudly toward the curb, where their newly procured transport sat parked in the gloomy shadows. "Twin Radio Flyers with greased axles. Silent, eco-friendly, and devastatingly maneuverable." "We are fleeing a residential felony inside little red wagons." "Put your ski mask on. Let us go ruin little Timmy's childhood." Molly pulled the dark wool over her face and hoisted an empty burlap sack, stepping silently onto the cold, dew-slicked pavement to begin the petty crime of the century.
