Rain hammered the lonely mansion. A scream shattered midnight silence. Lord Blackwood lay dead upstairs. Blood stained the marble floor. The butler discovered the body. Guests gathered inside the parlor. No one had seen anything. Detective Mira Vale arrived quickly. She studied the frightened faces. Someone here is a killer. The clock stopped at twelve. A kitchen knife was missing.
