Ashes of Love (1918)

In order to provide for her widowed mother, Louise Mordyke, Ethel marries Arthur Woodridge, a wealthy philanthropist who is considerably older than she. Although she respects her husband, Ethel resumes an affair with Howard Rosedale, the husband of her cousin Helen. Helen hires a detective, who discovers the lovers at a roadhouse. Rushing from the inn, Ethel is caught in a thunderstorm, after which she contracts pneumonia and dies, repentant but unconfessed. Arthur grieves so deeply that Louise and Helen fear for his sanity, and when Louise learns that he is contemplating suicide, she reveals the truth about Ethel's infidelity. Arthur, incredulous, denounces her. Following Howard's sudden death, however, Helen confirms the story. Louise and Arthur marry, and Helen weds an old friend.
