The old Victorian house stood silent beneath the harvest moon. Inside, Colonel Ashworth lay dead across his expensive Persian rug. A silver letter opener protruded from his gray tweed coat. Candle wax had pooled beneath the toppled mahogany writing desk. Detective Sarah Chen studied the body with careful, practiced eyes. No signs of forced entry suggested the killer knew him. The study window remained locked from the inside, oddly enough. Six guests had dined with him earlier that very evening. Each one now waited nervously in the adjoining drawing room. One of them was certainly lying about something important tonight. Sarah knelt beside the body and noticed torn paper scraps. Half of a burned letter rested inside the cold fireplace. The clock on the mantel had stopped at midnight exactly. Outside, thunder rumbled as the storm finally arrived in full. Somewhere among the guests, a murderer waited with steady nerves.
