The Woman in White by Wilkie Collins is one of my favorite books. It's long and very atmospheric...one of those gothic tales that keeps you up at night! When I saw it was going to be something I could enjoy on television, I was thrilled and honestly I was not disappointed with this adaptation. I haven't read the story in some time, but I believe it was true to the book. The characters were as I expected and very well done.
If you are looking for a classic gothic tale to enjoy, give The Woman in White a try.
