Molly unfurled the blueprint across the hood of their getaway minivan, smoothing the crumpled corners with theatrical reverence. "Behold," she said. "The Henderson residence. Birthday party for little Timmy, age seven. Forty-three confirmed guests, twelve of them screaming." Bill squinted at the paper. "That's a placemat from a pancake house." "It's symbolic, Bill. Stay focused." She tapped a syrup stain. "The presents pile here, by the bouncy castle. We strike during the piñata." "Why the piñata?" "Because nobody watches presents when there's candy raining from the sky. Basic human nature." Bill scratched his chin nervously. "And the parents?" "Distracted, exhausted, possibly drunk. We waltz in dressed as clowns, grab the loot, and vanish before anyone notices." "I don't do clowns," Bill said flatly. "You know my history." "One traumatic birthday does not define a man." "It defines this man." Molly sighed, rolling up the placemat. "Fine. You'll be the magician. Cape, top hat, the works. You distract them with card tricks while I load the wagon." "I only know one card trick." "Then do it forty-three times!" Bill considered this, then nodded slowly. "We're really stealing from children." "Spoiled children," Molly corrected, grinning. "There's a moral difference, and frankly, we're heroes."
