Rain lashed against the grand manor windows, blurring the already gloomy November twilight completely. A frantic butler, Mr. Finch, burst into the library, his face pale with utter despair. Lord Ashworth lay sprawled upon the Persian rug, a crimson stain blossoming across his velvet smoking jacket. The opulent room, usually filled with warmth and scholarly pursuits, now reeked of fear and sudden violence. Detective Inspector Davies arrived promptly, his experienced eyes already scanning the chaotic scene before him. A single, antique letter opener rested near the victim's hand, gleaming ominously under the chandelier's faint glow. Lady Ashworth shrieked from the doorway, clutching a delicate handkerchief, her voice trembling with evident shock. Every member of the assembled household appeared shaken, each individual possessing a carefully concealed secret undoubtedly. The air hung thick with unspoken accusations, a palpable tension settled heavily within the exquisitely decorated chamber. Davies noted a spilled glass of brandy and scattered chess pieces, small details potentially proving surprisingly vital. He signaled for his sergeant to secure the scene immediately, knowing uncovering the truth would be remarkably complex.
