Molly smoothed the grease-stained paper flat against the hood of their dented sedan, her expression deadly serious under the flickering alley streetlight. "Look at the blueprint, Bill." Bill adjusted his cracked spectacles and leaned over the metal hood, squinting in disbelief. "Molly, that is a Denny’s children's menu colored with a broken magenta crayon." "It is a tactical schematic of Timmy Higgins’s seventh birthday party. Now pay attention." Bill sighed heavily, pulling a half-eaten pretzel stick from the pocket of his faded trench coat. "I really feel like this is a new low for us." "A low? Bill, there is a four-hundred-dollar drone under that wrapping paper." "Along with three pairs of dinosaur socks and a plastic harmonica." "Collateral assets. We fence the socks to the neighbors." She tapped a violently scribbled star representing the patio table with the tip of her pen. "You are terrifying when you do financial forecasting." "Focus. Infiltration begins behind the hydrangeas. At fourteen hundred hours, the clown initiates balloon animals. That is our window." Bill asked, nervously tugging his collar, "What kind of window?" "Three minutes of chaos. Twenty sugar-crazed kids screeching for balloon swords. The parents will not see a thing." "What about Timmy's mother? She ran the Boston Marathon." "Neutralized." Bill froze mid-chew, his eyes widening with genuine alarm as he looked at his partner. "Molly, tell me you didn't buy tranquilizers again." "Better. I told Brenda next door the punch has artificial dye. She will trap Mrs. Higgins in wellness talk for forty minutes." "That is diabolical. What is my role?" "You are Professor Whimsical, the backup magician." Bill picked up the gaudy purple velvet cape draped awkwardly over the sedan's passenger headrest. "Why am I always dressed like an idiot?" "Because your facial structure naturally projects bewildered incompetence. It puts people at ease." "I could be an undercover uncle." "The cape hides the loot bags. While you palm a coin, I flank the bouncy castle." "Is the bouncy castle structurally sound?" "Avoid the north turret. It has a slow leak and smells faintly of apple juice." "Noted. What about the guard animal?" "A spaniel named Sir Paws-a-Lot. Two cocktail sausages and he will actively assist in grand larceny." "I packed high-end turkey bacon." "Excellent. Once cleared, we secure the drone, the motorized go-kart, and the Lego castle." "Can we keep the giant stuffed panda?" Molly fixed him with a frosty glare that could have halted an oncoming freight train. "No sentimentality. It takes up valuable cargo space." Bill whispered defensively, "He looks very polite, Molly." "We sell him. Extraction is at fourteen-fifteen. If a child approaches with sticky hands, run. We avoid contamination." "Understood. To the van?" "Street sweepers are out. We are using the tandem bicycle with the toddler trailer." Bill rubbed his weary eyes, looking at the rusty two-seater leaning against the brick wall. "I am not pedaling that." Molly shoved the felt hat into his chest without blinking. "You will pedal like the wind. Put on the top hat."
