Absolutely. Look how many Mrs de Winters are in the novel — as well as Maxim’s two wives (the second of whom doesn’t even get a first name, so she’s literally named purely by her role), there’s his dead mother and his living grandmother, who confuses the second Mrs de Winter with the first, and the ancestor, Caroline de Winter that both Rebecca and the narrator dress up as.
The name and the house continue, as does the importance of the heir (hence Max’s murder of what he believes to be he cuckoo in the nest, as well as his unfaithful wife), the individual women come and go. The role outlasts its occupants.
The first morning, when the second Mrs De Winter answers the house phone to Mrs Danvers and, not realising she’s being addressed, actually denies her own existence by saying ‘Mrs De Winter is dead’.
Max infantilises her throughout, patting her like a dog, correcting her manners and telling her she’s acting like an applicant after a housemaid’s job rather than the lady of the house, suggesting she dresses up as Alice in Wonderland for the ball.
Only after he tells her he murdered Rebecca does the narrative actually tell us they sleep together (I mean, we assume they do on honeymoon, but now we’re told they share a bed all night), and the narrator start taking control of the house, giving her own orders, changing menus. But Max likes her for being so unsexual, childish, disempowered, meek — because she’s the opposite of the entrancing, strong, charismatic, sexual Rebecca, who flouts patriarchal norms and heterosexuality alike (well, probably — strongly suggested in Max’s disgusted ‘she was not even normal’).
Of course, in the ‘now’, she’s the adult taking care of a childlike/prematurely aged Max.
Though what do other people make of the ‘aftermath’ in the present? Manderley is burnt, certainly, but why can’t they live in England — the land is still there, he’s still rich, they could restore/rebuild, or settle elsewhere etc. He can’t surely be at risk from the law with Rebecca’s suicide motive ‘proven’? Or why not make a home in France — there’s no need to live in a series of hotels. And why don’t they have children, as they planned? Is Max now impotent without his house, even if the land is still there to pass on?
