Heavy rain lashed furiously against the tall library windows tonight. Lord Blackwood lay completely motionless upon the expensive Persian rug. A silver dagger protruded horribly from his broad, motionless chest. Crimson blood slowly stained the floorboards beneath his lifeless body. Detective Miller carefully stepped over the threshold into the room. He immediately noticed a shattered teacup near the stone fireplace. The grandfather clock suddenly chimed midnight in the gloomy hallway. Someone inside this grand mansion was hiding a deadly secret. Nobody could leave the estate until the killer was found. Miller opened his wet notebook and began the dark investigation.
