I liked it, but I thought the same story could have been told in half as many pages. I mean, it is not a novel of ideas (like something written by, say, Dostoevsky or Faulkner); it is a genre book. With someone like Dostoevsky or Faulkner the story is secondary to the florid language and the profound ideas, so the length doesn't matter. With a story-driven book like The Woman in White, length does matter.

It is prolix. Reading a mystery suspense book where you are still left without resolution after 500 pages can be tedious and aggravating. Agatha Christie and Sir Arthur Conan Doyle did it better.
