i want to make a list of movies/books/etc where a major plot point is “mom helps daughter kill a man who hurt her, or at the very least helps her hide the body” but in general that is never what the actual plot is about, so it’s huge spoilers, which is ACTUALLY KINDA WEIRD now that i am thinking about it. with dad movies it’s the whole plot of the things, SOMEONE HURT HIS DAUGHTER AND NOW THEY’RE GONNA PAY
but i read a book once that was entirely about a girl going back to her hometown after twenty years and trying to reconcile with her mother after The Incident. then they finally reveal 80% of the way through the book that The Incident was that protag thought she’d killed her date rapist and had been scared to come back because she’d somehow made it twenty years without consequences, but actually she’d only seriously injured her date rapist. protag’s mom had found the guy while looking for her wayward daughter, realized what happened, and ran him over with her truck and buried the body under her garden. she never said anything because of Mom Code.
there was no indication at any point prior to this that this was a book about a murder. it was a heartwarming coming-of-age story about a woman entering her middle years learning to better understand her mother. that just happened to include covering up a murder. protag thought her mom was just an obsessive gardener.
