The old manor loomed darkly under stormy midnight skies. Rain lashed against cracked windows, echoing hollow through empty halls. Footsteps crunched softly on gravel, though no one remained outside. A single candle flickered, casting long shadows on bloodstained floors. The victim’s body lay stiff, a knife still buried deep. Fingers twitched faintly, though no breath moved their lips. Neighbors swore they heard screams, yet no one answered calls. The butler’s pocket held a torn, half-burned love letter. A locked door stood ajar, its key missing from the lock. Whispers slithered through the air, though no one spoke aloud.
