The rain-soaked manor creaked as twilight slipped into night deeply. Inside, a flickering chandelier cast ominous shadows on walls everywhere. The host, Lord Whitaker, raised his glass, smiling to guests. Suddenly, a scream pierced the air, silencing laughter and silence. All eyes turned toward the ballroom, where shadows danced ominously. There, on marble steps, lay a body, still in darkness.
