How does the author use foreshadowing in the novel, Tender Is the Night?

The first sense that we have that something is not right with the Divers' marriage comes in Book One, when Mrs. McKisco comes upon a "scene" between Dick and Nicole in the bathroom during the party. The event foretells Nicole's emotional problems and is the first of many such "scenes."

Also in Book One, Tommy Barban meets Rosemary Hoyt for the first time and tells her that he is very fond of the Divers, "especially of Nicole." Barban eventually takes Nicole away from Dick and marries her.

A foreshadowing of the violence that is about to enter the Divers' lives takes place in the train station as Abe North is about to depart. A woman whom Nicole knows shoots an Englishman for no obvious reason. The next day, Jules Peterson is found dead on Rosemary's bed, and Dick must hide evidence to keep scandal from engulfing them.
