Molly spread the blueprints across the table, knocking over a juice box. "The bounce castle is our entry point. We go in through the inflatable drawbridge." "That's just the front door," Bill said, squinting. "It's a bounce castle, Molly. Kids bounce in it." "Exactly. Nobody suspects a grown man bouncing." Bill rubbed his temples. "And the presents? Where are they?" "Gift table. Northeast corner, guarded by a clown named Sprinkles." She tapped the diagram. "Sprinkles is the wildcard." "You've been casing a clown?" "For three days. He takes a smoke break at two o'clock, right after the piƱata." Bill leaned back, arms crossed. "What about the parents?" "Distracted. There's cake." Molly's eyes gleamed. "Never underestimate the power of cake, Bill." "This is insane. We're stealing from children." "We're stealing from rich children," she corrected. "There's a difference. Their presents are basically luxury goods." Bill sighed, then pointed at a red circle on the map. "What's this?" "Goodie bags. We grab those on the way out. Bonus loot." "You're unbelievable." "I'm thorough." She rolled up the blueprints triumphantly. "Now, suit up. And Bill?" "What?" "Wear something festive. We need to blend in." Bill groaned. "I am not wearing the dinosaur costume again."
