Molly spread the blueprints across the sticky diner table, flattening them with a ketchup bottle and a bowl of creamers. "Entry point is the bouncy castle," she said, tapping the page. "Structural weakness, northeast corner." Bill squinted. "You want us to infiltrate through an inflatable?" "I want us to commando-roll through an inflatable. There's a difference." "And the guests?" "Seventeen hostiles, average height four feet, armed with juice boxes." Bill whistled low and stirred his coffee. "What about the mom?" "Brenda. Ex-PTA president. Do not engage." "Copy that." He leaned back, chewing a toothpick like it owed him money. "And the loot?" "Presents stack near the piƱata. We grab, we bag, we exfil through the garage before the cake hits the table." "What if they sing 'Happy Birthday' early?" "Then we improvise. You harmonize on the low end." Bill nodded solemnly, as though she'd asked him to defuse a bomb. He tapped the blueprint where someone had drawn a smiling unicorn in red crayon. "Molly." "What." "This is a placemat from Chuck E. Cheese." She didn't look up. "Reconnaissance, William. I've been inside. I know the terrain."
