Rain hammered the manor roof. Scream shattered the quiet night. Lord Blackwood lay dead upstairs. His study door stood open. The detective found strange clues. A bloody letter opener gleamed. No footprints marked the carpet. The window was locked inside. A grandfather clock had stopped. Its hands showed three fifteen. Someone knocked from the hallway. Detective Mara drew her pistol. The lights suddenly went out. A whisper came from behind. "You are late," someone whispered. Then the clock began ticking.
