Molly spread the blueprints across the sticky diner table, nudging aside a plate of abandoned pancakes. Bill leaned in, squinting through his reading glasses, which were decorated with tiny cartoon dinosaurs he refused to explain. "The bouncy castle is our weak point," Molly said, tapping the paper. "Too many witnesses. Too much bouncing." "I can bounce," Bill said defensively. "You threw your back out opening a yogurt last Tuesday." Bill adjusted his glasses. "That yogurt was sealed by the devil himself. What about the clown?" "Reginald the Magnificent. Former Navy. Do not engage." "A Navy clown?" "Do not engage, Bill." He sighed, tracing the floor plan with a crayon he'd stolen from the kids' menu. "So we go in through the ball pit, grab the presents during pin-the-tail, and exfil before cake." "Exactly. In and out. Nobody gets hurt." "What if someone offers us cake?" Molly froze. She hadn't considered this. "We accept the cake," she said solemnly. "To refuse would blow our cover." "Two slices?" "Don't push it." Bill nodded, then pointed at the corner of the blueprint. "Molly. Why is there a pony?" "That," she whispered, "is Plan B."
