Sobre el por qué del cambio del título del libro. (Preguntaba ayer alguien en el chat).
"According to Nagy, Bloomsbury Publishing wanted Highsmith "to finally claim the novel as her own and...because it had been known under the pseudonym of Claire Morgan she felt it was more appropriate to have a clean start...[Highsmith] always wanted to title it 'Carol' and so she did."
Highsmith later commented that The Price of Salt had come from something she was thinking of in the Bible. Nagy states that it is a biblical "reference to Lot's wife, the story of Lot's wife and the price of literally turning back." Like Lot's wife, Hagar, Carol (played by Cate Blanchett) can not return to her former life, pre-Therese, and a sham marriage that has long forced her to deny her true desires. Instead, she makes the most difficult decision a mother could make - to give up custody of her daughter - rather than become a shell of a person and let her real self disintegrate into a pile of indistinguishable grains of salt. At the moment of her decision she asks, "What use am I to her if I’m living against my own grain?”
