The cold rain fell hard on the old mansion roof while the heavy clock struck midnight slowly tonight outside here. A nervous servant walked down the dark hallway holding a flickering candle to see the path ahead clearly before him. He stopped suddenly when he heard a strange noise coming from the large study room at the very far end. The door was slightly open and he pushed it with his trembling hand to look inside the dark room then. A cold body lay upon the floor covered in bright red blood that had spread across the rug fully there.
