The rain poured heavily outside the abandoned manor that night. Inside a single candle flickered near the cold lifeless body. Blood stained the Persian rug in dark crimson swirling patterns. The butler discovered the horrific scene just after midnight struck. He immediately called the police to report the grim discovery. Detective Smith arrived to examine clues left by the killer.
