Here's the character for which The Woman in White is named, Anne Catherick. She's a frantic, vengeful woman who's escaped from an insane asylum, and for the first half of the story, the male protagonist believes her to be a ghost. She wanders the roads and outskirts of town, vowing to tell her secret to someone she must save. Anne is all sharp angles and gaunt limbs wrapped up in a shawl. She's supposed to be frightening at first, then sympathetic.
I'm not satisfied with this design, so I'll come back to it later.
