The old mansion stood silent beneath a bruised and heavy midnight sky that threatened rain for many endless dark hours. Inside the cold grand hall tonight, a single candle flickered beside the lifeless body of the very wealthy Lord Ashcombe. A heavy velvet curtain shifted slightly though no window stood open anywhere in the large cold sealed chamber at all. Detective Eleanor Gray stepped over the threshold and paused to study the silent unnatural dark scene before her, very carefully. The victim lay sprawled upon the expensive Persian rug with a cold silver letter opener deeply buried in his chest. A half filled crystal glass of expensive red wine sat completely untouched upon the very small marble table beside him. Outside, thunder rolled across the distant hills while sudden hard rain began to strike the cold windows with great fury. Eleanor slowly knelt beside the cold body and said very softly that this was surely no accident, but a murder.
