Molly crouched behind the hedge, peering at the backyard glittering with balloons, bunting, and a suspiciously heroic piñata. Bill unfolded a crayon-drawn map he’d stolen from the fridge invitation. “That’s the gift table,” Molly whispered. “It’s also guarded by a magician,” Bill said. “Never trust a man with doves in his sleeves.” “He’s doing balloon animals.” “That’s how they start.” Inside, children shrieked around a cake shaped like a dragon. Molly adjusted her party hat, which read BIRTHDAY LEGEND. “We go in smiling,” she said. “You distract the adults.” “With what?” “Your face. It raises questions.” Bill frowned. “Rude, but usable.” Molly pointed to a tower of wrapped boxes. “We grab the presents, switch them with empty decoys, then escape through the bouncy castle.” “The bouncy castle is not an exit.” “It is if you believe.” A small girl appeared at the hedge, holding a juice box like a detective’s badge. “Are you pirates?” she asked. Bill straightened. “Entertainment subcontractors.” “Can you juggle?” Molly elbowed him. “He can emotionally juggle.” The girl considered this. “Mom! The weird pirates are here!” Bill sighed. “Abort?” Molly watched six parents turn toward them. “No,” she said. “New plan. We steal cake.”
