Molly spread the blueprints across the sticky diner table, weighing down the corners with ketchup bottles and a half-eaten pickle. The floor plan of the Wigglesworth residence looked less like a fortress and more like a bouncy castle rental gone wrong. She circled the backyard in red Sharpie, tapping the inflatable unicorn that served as the primary obstacle. Bill slurped his milkshake, squinting at the guest list. Forty-two children. Three clowns. One magician of questionable reputation. The loot, according to their inside source—a disgruntled piñata vendor—included the new Nintendo, a remote-controlled drone, and a suspiciously expensive American Girl doll with real pearl earrings. Amateur hour, he thought, cracking his knuckles over a basket of onion rings. "We go in dressed as balloon animals," Molly whispered. Bill choked on his shake, dabbing chocolate from his beard with a crumpled napkin. He sketched escape routes through the petting zoo, noting the goat's suspicious side-eye from last week's reconnaissance. They would time their exit with the piñata break, vanishing into the confetti chaos like phantoms with oversized gift bags. The cake, Molly decided, was collateral. The presents, however, were destiny.
