The rain lashed against the manor windows, mimicking the frantic rhythm of Eleanor’s anxious heart beating fast. A chilling draft snaked through the grand library, stirring dust motes dancing within the fading candlelight glow. Lord Ashworth lay sprawled across the Persian rug, a crimson stain blooming on his exquisitely tailored waistcoat. Inspector Davies surveyed the opulent room, his keen eyes absorbing every detail with methodical precision and care. A priceless antique clock ticked relentlessly onward, measuring the passage of time and the stillness of the victim. Lady Beatrice sobbed quietly into a lace handkerchief, her grief appearing genuinely profound and utterly sincere. The assembled guests exchanged uneasy glances, a palpable tension thickening the air amongst the gathering gloom. A single, overturned chess piece rested near the body, a black queen lying abandoned and strangely out of place. The aroma of expensive brandy mingled with the metallic scent of blood, creating an unsettling combination for all present. Young Mr. Hawthorne nervously adjusted his spectacles, seemingly overwhelmed by the gravity of the tragic circumstance unfolding. Outside, the wind howled like a tormented spirit, adding an eerie soundtrack to the unfolding investigation's beginnings.
