The foggy manor whispered secrets as twilight draped the gardens. Detective Marlowe arrived, his coat flapping softly in midnight wind. Inside, the dining hall glowed with candles and uneasy guests. A sudden scream shattered silence, echoing deep off marble corridors. The victim lay motionless, a crimson ribbon entwining his wrist. Marlowe stared, noting the missing knife and lingering perfume soft.
