The back of the rusty surveillance van smelled like wet carpet, stale corn chips, and desperate criminal ambition. Molly taped a crude blueprint onto the corrugated steel wall, smoothing down the crinkled edges with deliberate, almost surgical precision. Bill watched her from the shadows while slowly chewing on a cold chicken nugget. Outside the tinted rear glass, suburban tranquility buzzed innocently under the bright Saturday afternoon sun. "Look at the perimeter," Molly whispered, tapping the crayon map. "The bounce house sits on the northern flank. If the wind picks up, the anchor lines could easily compromise our primary extraction route." Bill swallowed hard, squinting at the pastel doodles depicting swings, plastic slides, and aggressively shaded flower beds. "Are we talking about Mrs. Higgins and her backyard?" "Code name Sierra Sandbox, Bill. Stay professional." Bill leaned forward, adjusting his scratched sunglasses. "Molly, it is just a children's birthday party." "Which means maximum operational security," she replied, her eyes narrowing underneath the rim of an itchy black beanie. "High sugar hostiles with zero impulse control. They are small, completely unpredictable, and violently sticky." Bill sighed heavily, brushing stale crumbs from his grease stained jacket. "What is the actual haul? You promised diamonds earlier. I distinctly heard the word diamonds." "I said retail equivalent to diamonds, adjusted for inflation," Molly snapped, pacing the narrow strip of rust eaten metal floorboards between them. "Timmy requested vintage robotics, unopened construction bricks, and three remote controlled speedboats. The mother guards the gift perimeter." "She makes remarkably dry brownies," Bill noted dryly. "Besides, her brother sold me a broken lawnmower, so the woman owes us." Molly ignored the interruption entirely, aggressively highlighting a tall floral hedge with an oversized purple marker. "At fourteen hundred hours, a substandard balloon artist provides sensory distraction." Bill asked, frowning. "Why substandard?" "His shrieking rubber poodles provoke mass panic," she explained, checking a cheap golden pocket watch with theatrical urgency. "While forty children scream, we breach the laundry chute." "I cannot fit down a laundry chute, Molly." Molly rolled her eyes and shook her head in sheer exasperation. "I coated the intake with unsalted butter," she hissed. "You slide like a majestic walrus, bag the wrapped loot, and shove it through the dog flap into my wheelbarrow." Bill paused, thoughtfully contemplating the terrifying physics involved in such a descent. "And the golden retriever?" "Barnaby is a mercenary," she whispered coldly. "I brought two pounds of cocktail sausages. His silence is bought." Bill asked, his hopeful eyes suddenly gleaming with genuine, unabashed greed. "Can we steal the cake?" "No confectionery assets, no detours, and absolutely no frosting," Molly growled, brandishing an enormous plastic walkie talkie. "Synchronize watches. Zero hour begins now." "If I get tackled by a mother in yoga pants, Molly, I am snitching on everyone." Bill pulled on thick yellow dishwashing gloves with a sharp snap that echoed against the vehicle's hollow frame. Molly shouldered her burlap sacks, unlatched the rusty door handle, and peered cautiously out into the suburban battlefield.
