Molly crouched behind the hedge, peering at the backyard swarm of balloons, cupcakes, and sugar-powered children. Bill unfolded a crumpled party invitation like it was a museum blueprint. “Target: presents table, northwest of the bouncy castle,” Bill whispered. “That’s southeast,” Molly said. “I’m holding the map upside down.” “It’s a dinosaur napkin.” “Still cartographic.” Molly adjusted her tiara disguise. “We are not frightening children, Bill.” “Obviously. We enter as entertainers.” “You can’t juggle.” “I can drop things rhythmically.” A shriek of laughter rose as a clown slipped on frosting. “Distraction’s already hired,” Molly said. “We move after cake.” Bill squinted. “What if the presents are full of socks?” “Then we have committed seasonal laundry.” “Morally complicated.” A small boy toddled to the hedge and stared at them. Molly froze. Bill waved. “Are you pirates?” the boy asked. “Accountants,” Bill said. “Birthday accountants,” Molly added. The boy nodded solemnly. “Mom says presents go inside after games.” Bill gasped. “Intel!” Molly sighed and produced a wrapped toy from her bag. “New plan. We add this to the pile and leave.” “But the heist!” “We’re stealing their suspicion.” Bill considered. “Elegant.” “Also, you’re wearing the piñata.”
