The grand estate loomed under storm clouds, its windows dark. Rain tapped softly against glass while shadows stretched long. A single candle flickered weakly on the mahogany desk. Footsteps echoed through the hall, slow and deliberately muffled. The butler paused outside the study, hand trembling slightly. Inside, the master lay sprawled across the Persian rug. Blood pooled beneath his head, still warm to touch. A silver letter opener glinted under the dim chandelier’s glow. The clock struck midnight as the butler gasped loudly. Somewhere upstairs, a door creaked shut with eerie finality.
