Molly spread the blueprints across the sticky diner table, narrowly avoiding a puddle of syrup. Bill squinted at the crayon drawings. "This is a napkin," he said. "It's reconnaissance," Molly corrected. "Tommy Pemberton's turning seven on Saturday. His mother invited forty kids. Forty. Do you know what forty rich kids means?" "Germs?" "Presents, Bill. Mountains of presents. Xboxes. LEGO sets. Those little scooters that cost more than my car." Bill scratched his stubble nervously. "Molly, we robbed a casino last year. A casino. Now we're knocking over a birthday party?" "The casino had cameras. The casino had guards. You know what Pemberton Manor has? A clown named Jingles and a bouncy castle." "I don't like clowns." "Nobody likes clowns. That's why it's the perfect cover." She jabbed the napkin. "We dress as entertainers. We wait for cake time. Sugar crash hits, kids go feral, parents are distracted wrestling them into minivans. We load the trunk and vanish." Bill sighed. "And if we get caught?" "By who? Tommy? He's seven. He can't even tie his shoes." "His dad's a lawyer." "Then we'll steal his briefcase too," Molly grinned. "Eat your pancakes."
