The old manor stood silent beneath the heavy midnight rain. Detective Harlan paused at the gate and studied the windows. A single candle flickered behind the cracked library glass pane. He pushed the iron gate open and stepped inside carefully. Wet gravel crunched beneath his boots like brittle broken bones. The front door hung ajar, swaying in the cold wind. A copper smell of blood filled the dark front hall. The master lay dead across the wide marble entrance floor. A silver letter opener rested beside his outstretched right hand. His wide eyes stared upward with one final frozen shock. Soft footsteps echoed somewhere above him inside the dark house. Harlan drew his revolver and climbed the shadowed grand stairs. Someone inside this house had already killed once this night. He intended to find the killer before dawn fully arrived.
