I have hesitated putting this on here as I have so few details but here goes.
I was read this story in infant school in the mid 80's.
- The story has children in it at least 1 boy and 1 girl these may be siblings.
- They find a tree with a door in it not at the base but half way up.
- The tree is in some woods near a house.
- They manage to get through the door..... and that's where my memory goes blank grrr.
The story had a very fantasy feel to it and I remember the book been large and thick so it might of been in a book with several stories. It was definitely hardback. I don't remember the cover unfortunately.
