The storm arrived precisely at midnight, thrashing rain against the manor’s tall, dark windows. Detective Harding stepped from his car, the gravel crunching like bones beneath his weary feet. Inside the library, Lord Ainsley lay still, a silver letter opener protruding from his velvet smoking jacket. A single drop of blood marred the Persian rug, its pattern resembling a faded, forgotten map. The grandfather clock had stopped at twelve-oh-three, marking the moment when secrets decided to stop sleeping. Harding noted the victim’s cold hand still held a torn scrap of paper with one word: “Corsica.” Outside, lightning cracked, illuminating the faces of six terrified guests huddled in the grand, shadowed hallway.
