Cold rain battered the glass. Detective Vance checked his watch. Midnight had passed hours ago. Heavy shadows filled the hallway. A broken lamp lay nearby. Blood pooled under the sofa. Lord Harrington was definitely dead. A silver dagger pierced him. His pale eyes stared upward. Nobody heard the fatal scream. Vance put on leather gloves. The killer left no footprint. Locked doors secured the room. Someone inside committed this crime.
