Molly crouched behind the bouncy castle like a burglar in a migraine, studying the suburban battlefield through binoculars decorated with cartoon sharks. Streamers whipped across the garden, a hired magician fought with a balloon octopus, and twenty sugar-crazed children ricocheted between folding chairs with the tactical discipline of startled pigeons. Beside her, Bill unfolded a hand-drawn map of the house that looked suspiciously like a treasure island designed by a tired pirate. “Front gate’s chaos,” Molly whispered. “We go through the caterer, charm the clown, grab the loot, vanish smiling.” Bill adjusted his clip-on bow tie, the kind criminals wore when they wanted to look honest and instead looked recently fired. The presents were stacked by the patio doors in a glittering mountain of dinosaurs, dolls, and educational plastic destined to be immediately ignored. A mechanical pony guarded them with dead-eyed serenity. Bill nodded, then frowned at the clown. The clown was tall, broad, and smoking behind the shed with the solemn air of a man reconsidering every decision since birth. Molly admired that. Real professionals respected despair. The gate burst open as another aunt arrived carrying cake. Bill straightened, inhaled courage, and marched toward destiny, trailed by Molly and an inflatable sword stuck to his shoe.
