" There is no such thing as a plain fact of murder. Murder springs, nine times out of ten, out of the character and circumstances of the murdered person. Because the victim was the kind of person he or she was, therefore was he or she murdered! Until we can understand fully and completely exactly what kind of a person [she] was, we shall not be able to see clearly exactly the kind of person who murdered her. From that spring the necessity of our questions. "

― Agatha Christie , Evil Under the Sun (Hercule Poirot, #21)
