The rain hammered the manor roof as midnight approached silently. Detective Harlan found the body beside the shattered library window. Blood stained the Persian rug under the victim's pale hand. A silver letter opener lay abandoned near the open door. Guests whispered in the hallway while thunder rolled outside again. Nobody admitted hearing the scream that woke the entire household. Harlan studied every face and trusted absolutely none of them. The locked study held secrets darker than this stormy night.
