Rain lashed against the windows of Blackwood Manor, obscuring the already gloomy twilight evening outside. Detective Inspector Davies arrived, pulling his trench coat tighter against the chilling, damp air. A frantic housekeeper, Mrs. Higgins, met him at the door, her face etched with visible distress and fear. The deceased, Lord Ashworth, lay sprawled dramatically upon the Persian rug in the library’s center. Investigators immediately noticed a crimson stain spreading across the intricate, velvet upholstery surrounding him. A single, antique letter opener rested ominously beside his lifeless, outstretched hand, gleaming darkly. The room smelled faintly of sandalwood and something else, a subtle, unsettling metallic odor lingered there. Outside, a storm continued its relentless assault, adding to the increasingly ominous, somber atmosphere.
