There is a glaring architectural problem in your new husband’s ancestral manor.
If you point this out to anyone, they will accuse you of being a spoiled urban-dweller.
There are also one or more forbidden rooms - possibly an entire forbidden wing.
Everyone agrees this is a normal feature of houses.
Someone has all the keys to the house, but it isn’t you.
An elderly servant confuses you for “the other one”.
Your normal wardrobe has mostly transformed into white, fluttering night gowns, to symbolize both marriage and GHOSTS, but no one says that - it’s subtext
You either don’t have a first name or have forgotten it; you are only referred to as “Mrs. DeFranderly” or “my Lady” or possibly “my dear”, assuming that you even see your husband on a semi-regular basis
Speaking of which - where is your husband?
You haven’t slept in the same bed since your honeymoon or possibly ever. Which is kind of a bummer, honestly, because you likely married this man with a creepy house primarily for the sexual chemistry, which sounds bad, but consider that romantic and sexual norms are quite restrictive and stifling in your time period, so, listen, you do you. But in fact, you actually still know very little about him, come to think of it, like, is he a cat person or a dog person, does he like blue cheese or not - these are the kind of questions that you realize you should have been asking all along instead of being all “oh my god, I DO love ruined houses in the countryside, you know me so well, dear Bennington!”, etc.
