Molly spread the blueprints across the sticky diner table, knocking over a ketchup bottle. "Okay, Bill, listen up. The party starts at two. Cake at three. That's our window." Bill squinted at the paper. "This is a placemat." "It's a tactical placemat. Focus." She jabbed a crayon at a drawing of a castle. "Bounce house here. Presents table here. Clown does balloon animals at two-thirty." "I hate clowns." "Everyone hates clowns. That's why he's the perfect distraction." Bill leaned back, crossing his arms. "Molly, these are seven-year-olds. We're stealing from seven-year-olds." "We're stealing from their parents, technically. The kids haven't earned equity yet." "That's not how children work." "Bill." She grabbed his wrist. "Do you know what's in those boxes? Limited edition action figures. Unopened. Mint condition. One of them is going for eight hundred bucks on the collector market." He paused, chewing his toast. "Eight hundred?" "Now you're listening." "What about the parents?" "Distracted. Wine, mostly. Trust me, I've scouted three birthday parties this month." "You've been casing children's parties?" "I'm thorough." Molly folded the placemat carefully. "Wear something festive. And Bill?" "Yeah?" "Bring the stroller. We're going in as aunt and uncle."
