Juvenile/YA..girl visits relatives, removes rowan branch above tunnel lets "witch" escape

Don't know why these things just pop in my head but they bug me when they do. LOL Help a crazy lady out here. Here is what I remember..

*Not sure of the year written
*Girl goes to visit relatives (I think in England or somewhere in the UK)
*There is a old creepy (railway) tunnel and cousins challenge her to walk all the way through without a flashlight.
*above the entrance of the tunnel is a rowan tree growing
*girl climbs up and breaks off rowan tree to use as a guide in the tunnel (by dragging it along the wall)
*toward end of tunnel she sort of fights something trying to hold her back
*turns out there was a "witch" imprisoned in tunnel and held captive by the rowan, which apparently repels witches, at either end --that is why she had a hard time going out other end of tunnel--the witch was fighting against the rowan growing there
*because witch escapes she brings on unseasonably cold winter like weather to the area.

Wish I could remember more

IS this one of the CS Lewis books? I have only read the one that was made into a movie so I'm not sure.

Not any of the Narnia or Perelandra books, no. Don't know enough about his shorts and unpublished stuff to say about that.

It almost sounds like some of the Susan Cooper Dark is Rising sequence, but it's been forever and ever since I read any of her work, so I can't say for sure. Anybody read them more recently?

Definitely not from the Dark is Rising sequence. The winter weather, tunnel and witch-like character remind me of Fours Crossing by Nancy Garden, but none of the other details match.

"The Frightened Forest" by Ann Turnbull?

I love you people on here, you are so awesome. The Frightened Forest it is.

I have read (and think I have a copy) of Fours Crossing. Also a decent book.

Thanks loads!
