Addressing the Femme Fatale in 'The Lady in White'

Subconciously I have woven in themes of film noir unintentionally that have referenced the representation of the female figure within the conventions of this age of film. The main character's lust for her married partner and the dark seacrecy of their relationship reflects that of 'The Big Sleep' (1958) which follows the path of female dominance and manipulation. My character however is putting an end to the affair and is trying to find a better man, which is of course is when her bitterness spirals to her devestating fate. She is by no means a pure individual, her venegence on her partner is to leave both the necklace he gave her and the letter of confession for his wife to find in an attempt of fulfillment. The idea of 'The Lady in White' is perhaps an etherial one, the desire to become a woman who's non existant, but perfect and pure in every way. Though she is a character that is morally corrupt, she does intend to make ammends by running away to start a new life. The main villain of this film is the male character whose exploitation of both women leads his wife to point his gun in his face after killing his mistress, inevitably getting his comeuppance in the end. Not having a clear ending is essentially the art of storytelling, sometimes there needs to be an audience's conclusion rather than always having a rounded finale.
