The old manor creaked as twilight slipped through cracked windows. Inside, a polished mahogany desk held a single candle still. The clock struck midnight, echoing across the silent hall cold. A shadow slipped past the doorway, unnoticed by guests quietly. Suddenly, a blood‑stained hand emerged from the darkness shivering. The scream pierced the night, sealing the manor's fate forever.
