Molly flattened the party invitation against the rain-slick alley wall and grinned. Through the kindergarten gym windows, streamers bobbed like surrender flags, and a mountain of wrapped presents sat beneath a cardboard castle. Bill, wearing a borrowed balloon hat, adjusted his gloves and tried not to look emotional. “Those boxes are begging for liberation,” he whispered. Molly peered at the timetable on her watch. “Cupcake break in seven minutes. That’s our window.” Bill nodded toward the side door, where a paper sign read, PLEASE WASH HANDS BEFORE ENTERING. “Nice to know the defense budget is low,” he said. Molly handed him the tiny trolley they’d stolen from a supermarket display. “We roll in as the clown’s equipment team, grab the gifts, and vanish before anyone notices the missing dinosaur-themed bag.” Bill blinked. “And if they do?” Molly shrugged. “We blame the magician. Everyone blames the magician.” Inside, a speaker began playing “Happy Birthday” with enough enthusiasm to frighten a horse. Bill swallowed, squared his shoulders, and smiled like a man about to commit a highly organized felony. Molly touched the door handle. Somewhere within, a child laughed, and the presents waited, glittering with terrible innocence.
