It was a collection of horror stories for children I think and one of them was a lady with a burned or scarred face who possibly came out of a painting. She was called Rhoda or Roda or something like that. It had these simple ink illustrations and I remember that one.
It had another story where a boy (I think) was hiding and heard the ghosts of some body snatchers - it may have been a retelling of Burke and Hare.
I’m English if that helps and I think I would have read this sometime in the 90’s.
Sorry, that’s so vague but those are the two that I think I remember.
