The ending's sole happy aspect, that Nicole leaves Dick and becomes genuinely happy with a new husband, didn't reflect the final outcome of Nicole's Expy, Zelda Fitzgerald. Zelda was locked up in an insane asylum for the rest of her days, then dying when a fire broke out in said asylum.
Vindicated by History: Many critics disliked the novel's use of Anachronic Order on its first release, prompting Fitzgerald's plan to revise the entire work into a more conventional chronological narrative. This edition was completed by Malcolm Cowley after Fitzgerald's death and released in 1951 - by which time critics had warmed up to the original edition of the book. Cowley's version is now held in lesser esteem than the original.
