Molly crouched behind the hedges, peering at the rented manor where balloons bumped against the windows like nervous ghosts. “That’s the place,” she whispered. “The children are inside, shrieking with sugar and trust.” Bill adjusted his gloves and frowned at the paper crown on his head. “I still don’t like the crown,” he said. “It makes me look festive.” “Good,” Molly replied. “Festive people are ignored.” From the garden, came the wobble of a bouncy castle, the tinny warble of a clown’s trumpet, and the blessed clatter of adults pretending this was fun. Through the open patio doors, towers of wrapped gifts gleamed under fairy lights, each one tagged with a child’s name in glittery marker. Bill’s eyes widened. “That’s a lot of loot for a room full of people who can’t spell ‘tomorrow.’” Molly smiled. “We go in as entertainers.” She lifted a cheap accordion from the grass. “You’re the magician’s assistant.” Bill stared. “I’m not wearing tights.” “Then be the magician.” A burst of laughter rolled across the lawn as the clown slipped on a cupcake and performed a perfect accidental somersault. “Now,” Molly breathed. They straightened their fake mustaches, smoothed their borrowed vests, and walked toward the party, looking like the worst surprise in the middle of the best birthday.
