How does the author use foreshadowing in A Lost Lady?

Captain Daniel Forrester's high moral standards foreshadow that he will not allow himself to remain rich, while those who depended on him to protect their money lose most of what they have. In the end, Forrester and his wife are forced to rent part of their property to a crude man, who destroys its beauty and encourages Mrs. Forrester to invest money in illegal ventures.
