The old mansion groaned a welcome for the guests arriving. Rain lashed the windows, a dismal drumming rhythm. Lord Ashworth, our host, poured his finest brandy. He offered a toast before dinner, smiling strangely then. The fire cast long shadows across his pale face. Lady Ashworth wore her pearls, glittering and cold. She whispered to herself, barely audible to anyone. A serving girl stumbled while carrying a silver tray. The ornate grandfather clock chimed midnight with a loud toll. Suddenly, a piercing scream echoed throughout the great hall.
