Tender is the Night by F. Scott Fitzgerald is the story of the rise and pitiful fall of Dick Diver, a promising young psychoanalyst and his wife, Nicole, who is also one of his patients. It is commonly assumed that the plot is modeled on the author's own life and his relationship with his wife Zelda, who struggled with mental illness throughout their marriage.

• "But to be included in Dick Diver’s world for a while was a remarkable experience: people believed he made special reservations about them, recognizing the proud uniqueness of their destinies, buried under the compromises of how many years. He won everyone quickly with an exquisite consideration and a politeness that moved so fast and intuitively that it could be examined only in its effect. Then, without caution, lest the first bloom of the relation wither, he opened the gate to his amusing world. So long as they subscribed to it completely, their happiness was his preoccupation, but at the first flicker of doubt as to its all-inclusiveness he evaporated before their eyes, leaving little communicable memory of what he had said or done."

• "Nicole was the product of much ingenuity and toil. For her sake trains began their run at Chicago and traversed the round belly of the continent to California; chicle factories fumed and link belts grew link by link in factories; men mixed toothpaste in vats and drew mouthwash out of copper hogsheads; girls canned tomatoes quickly in August or worked rudely at Five-and-Tens on Christmas Eve; half-breed Indians toiled on Brazilian coffee plantations and dreamers were muscled out of patent rights in new tractors—these were some of the people who gave a tithe to Nicole, and as the whole system swayed and thundered onward it lent a feverish bloom to such processes of hers as wholesale buying, like a flush of a fireman’s face holding his post before a spreading blaze. She illustrated very simple principles, containing in herself her own doom, but illustrated them so accurately that there was grace in the procedure, and presently Rosemary would try to imitate it."
