The bell tolls loudly within the empty old hall tonight. Detective arrives late looking very serious and feeling quite tired. A body lies still upon the cold marble floor now. A knife rests near him with a dark red stain. He looks around slowly searching for clues within the room. One glove remains lost somewhere deep inside the dark room.
