Fog draped the manor's windows. Thunder rumbled beyond the hills. Inside, candles flickered weakly, trembling. Detective Marlowe arrived, coat soaked. He sensed unease in shadows. A scream shattered midnight silence. Guests gathered, eyes widened, trembling. The body lay sprawled, lifeless. Blood stained the antique rug. Marlowe knelt, inspecting crimson clues. A whisper echoed: 'Someone knows'. The investigation had just begun.
