The old manor loomed dark and silent under moonlight. Rain pattered softly against the cracked front windowsill. A single candle flickered weakly on the hall table. Footsteps echoed strangely through the empty, dusty air. The door creaked open with a whisper of wind. A gloved hand gripped the cold brass door handle. Shadows stretched long across the marble floorboards. Someone had left a single, bloodstained handkerchief behind. The air smelled faintly of lavender and something metallic. A distant scream pierced the still, unnatural quietness.
