It is amazing (to me, at least) how so much pulp fiction of the 50s and 60s is well-written, especially the kind by women like March Hastings.
Though definitely a sign of their times (often failing to have a happy ending because popular culture, and even the postal office, demanded it), novels like Three Women can still have value today. Society has certainly progressed these past five decades, but very few gays and lesbians manage to escape their lives untouched by hatred, whether from the world in general or their own family members.
Also amazing is how once you peel away the contributing factors to what sets up the major conflict in Three Women, you are actually addressing an age-old question both straight and gay people face in relationships no matter the era: What do you when your partner's ex is always in the background, even when she isn't physically there?
Two of the three women in the title definitely and tragically fall victim to a society that tells them being gay is not only "wrong," but "sinful" as well. The third woman, Paula, falls victim not so much to homophobia as she falls victim to her own impatience and lack of faith in the woman she loves. The reader wonders if things would end differently if Paula just didn't push so much.
No doubt about it...Three Women does not have the happy ending anyone who believes in true love would like it to have. Refreshingly, though, it never condemns the love found within these pages.
I could be reading too much into it out of some hopeful need to see it, but I think Hastings was actually suggesting tragedy befalls everyone when a harsh world dictates who should and shouldn't be able to love each other.
