# The Birthday Bandit Briefing Molly spread the grainy surveillance photos across the kitchen table. Bill whistled low, studying the fortress of wrapped packages stacked near the bounce house. "So we're really doing this," Bill muttered, running his hand through his hair. "A six-year-old's birthday party." "The haul is unprecedented," Molly replied, pointing at each gift. "Look at that pile. Custom action figures, gaming systems, a real pony in the backyard." Bill leaned back in his chair. "How do we even transport a pony?" "We'll improvise." Molly pulled out a floor plan sketched on a napkin. "You go through the kitchen entrance at 2 PM, when everyone's distracted by cake. I'll create a diversion near the piƱata." "And the parents?" "Busy fighting over the last juice box." Molly grinned wickedly. "We'll be gone in seven minutes tops." Bill studied her face, then the photos again. "This is insane, you know." "Completely ridiculous," Molly agreed. "But the payoff alone from reselling these toys could fund three legitimate heists." "When do we start?" "Saturday," Molly said, sliding him an invitation. "I already RSVP'd for both of us."
