The manor clock struck midnight. Outside, rain smothered the gardens. Inside, someone had stopped breathing. Clara discovered him before dessert. Lord Ashcombe lay beside the fireplace. His champagne glass remained upright. His throat wore crimson pearls. Nobody admitted hearing a scream. Everyone remembered hearing the clock. Clara knelt without touching him. Something glittered beneath his tongue. A tiny key, freshly polished. The housekeeper recognized it immediately. Then she locked the doors. Clara watched her trembling hands. “That room,” the housekeeper whispered. “We buried its key yesterday.” Upstairs, a floorboard slowly creaked. Every guest stood downstairs, listening.
