Thunder rolled over old Blackwood Manor as midnight struck hard. Inside the dark library a man lay dead beside books. His silk tie was twisted tight around his pale throat. Candles guttered low while five guests waited in the hallway. Each one had motive, means, and a very careful alibi. Detective Marlowe entered quietly and closed the heavy oak door. Nobody spoke at all until the clock began chiming again. Somewhere inside that house a killer was still quietly listening.
