Rain battered the dark window. Cold tea sat on desk. Detective Vance checked his watch. Midnight arrived with heavy silence. Suddenly, the front phone rang. Vance lifted the black receiver. A frantic voice whispered softly. Lord Harrington is dead now. Blood stained the library rug. Someone murdered him this evening. Vance grabbed his worn coat. A killer walked among us.
