Rain hammered the old mansion. Detective Mara arrived precisely midnight. The butler opened creaking doors. Blood stained the library floor. Lord Blackwood lay quite still. His eyes stared beyond death. A shattered glass rested nearby. No footprints marked dusty windowsills. Mara noticed missing fireplace poker. Someone had locked every window. The murderer remained inside still.
