Detective Mara Quinn arrived at Blackwood Manor before midnight struck. Rain hammered the windows while thunder rattled the old house. Inside, Lord Henry Blackwood lay dead beside his overturned chair. A silver knife protruded from his chest, dripping crimson blood. Seven guests stood silent, watching Mara with carefully hidden fear. Each guest claimed innocence, yet each glance betrayed secret guilt. Mara noticed muddy footprints leading toward the locked library door. Someone inside this house killed him, she whispered very softly. Then the lights flickered, died, and someone screamed in darkness.
