Playing with fire (1916)

Jean Servian's eyesight is failing and is desperate for money, marries wealthy widower Geoffrey Vane after telling him that he must be satisfied with her gratitude rather than her love. Then, following an affair with artist Philip Derblay, who finally leaves her, Jean settles down to a quiet, boring life with Geoffrey, who knows nothing about her failed romance. Years later, however, after Lucille, Geoffrey's daughter by his first wife, becomes engaged to Philip, Jean feels compelled to tell the story of her own affair with him. The disclosure has little effect as Lucille makes no change in her wedding plans, but then, when she breaks in on a violent argument between Philip and Lucille, Jean accidentally shoots and kills her former lover. A trial results in her acquittal, however, after which Jean realizes that she really does love Geoffrey, who easily forgives his wife for her past indiscretion.
