Bernard Capes, The skeleton key (1920)
“ Would that consideration be enough in itself to goad him on to murder? With a man of Ridgway’s character and trained cautiousness of disposition I did not think it probable. Assuming, then, that the murder were his act, what more overmastering motive could have driven him to it? What but jealousy, the one passion uncontrollable by even the most self-disciplining nature. He was himself passionately enamoured of his own beautiful decoy, and she had betrayed not only his interests but his love. The crime had been, in the expressive French phrase, and in the fullest sense, a crime passionel. ”
