Rain lashed against the grand manor windows, blurring the manicured gardens beyond in a grey haze. Inside, Inspector Davies surveyed the opulent library, noting the unsettling silence permeating every shadowed corner. Lord Ashworth lay sprawled upon the Persian rug, a crimson stain blooming across his tailored waistcoat. A single, antique letter opener rested nearby, gleaming faintly under the elaborate chandelier's dim light. The air hung heavy with the scent of old books, expensive cigars, and a chilling premonition of deceit. Lady Ashworth wept dramatically upon a velvet chaise lounge, clutching a lace handkerchief to her trembling face. The butler, Mr. Finch, stood rigidly by the doorway, his expression unreadable despite years of impeccable service. A young, nervous maid wrung her hands, whispering anxieties about a dreadful noise she distinctly heard earlier. Davies adjusted his tweed jacket, examining the scene with a practiced eye, ready to unravel this dreadful mystery. He knew instinctively that beneath the veneer of wealth and propriety lay a web of dark secrets and betrayals.
