This has bugged me on and off for years. When I was younger (late 80s - early 90s) I'm sure I read a book from the local library in the UK. I don't remember many details. I think that it was set around the War of the Roses, and was from the perspective of a child protagonist. I remember there being a carved Tudor rose in a bed room, and I think that when pushed it unveiled some kind of secret.
That's all I remember - and I have never known whether I imagined it, or whether it was a real book. What book was this?
