Rain lashed against the grand manor windows, blurring the already fading twilight hues dramatically. Inside, Lord Ashworth lay sprawled upon the Persian rug, a crimson stain blossoming outwards. The opulent study smelled faintly of sandalwood and something else, something metallic and disturbingly wrong. A single overturned chessboard sat beside him, ivory pieces scattered like fallen soldiers helplessly. His loyal butler, Jeeves, discovered the scene and immediately alerted the local constabulary with trembling hands. Detective Inspector Davies arrived promptly, his trench coat dripping, surveying the room with keen, observant eyes. A priceless antique clock ticked rhythmically in the corner, seemingly oblivious to the tragedy unfolding before everyone. Lady Ashworth shrieked from the hallway, her silk gown rustling as she rushed toward the gruesome discovery swiftly. The flickering fireplace cast dancing shadows across the walls, concealing secrets within its warm, deceptive glow. A half-finished glass of brandy rested on the mahogany desk, inviting speculation and raising unsettling questions. Constable Miller secured the perimeter diligently, attempting to keep morbid onlookers away from the unsettling details. Each member of the household gathered nervously in the drawing-room, whispering anxieties and casting suspicious glances intensely. The chilling silence was broken only by the rain and the detective's methodical steps across the wealthy floor.
