I’m looking for a book that I read about 15 years ago that was already well aged at the time I read it, probably from the 70s or 80s. It was on a classroom bookshelf in my elementary school. It’s about a girl who I think moves… from the city to the country with her mother for sure, possibly her father has died. She isn’t too pleased about the move but eventually while exploring their new large country house she discovers the servants passage and a room where it appears an old lady used to live, I think. She also likes to play in the apple cellar, befriends someone at school, and there is a not well-liked older fellow who lives in a dark small house who I think may have lived in their house at one point? I may totally wrong on some of these things because I was young when I read it, but I think I’m right.
Thanks!
