It was a stormy night when the famous detective received the urgent call about a murder in the old mansion. Upon arrival he saw the lifeless body of a wealthy man lying in a pool of blood near the desk. No obvious weapon appeared visible anywhere at the scene suggesting the murder had been carefully planned by a cunning individual.
