Sarah Waters' The Little Stranger
Oh my gosh, this book CREEPED ME OUT. I'm so glad I read it while it was still light out, or I'd be too scared to sleep! The story takes place in England in the 1940s in a big fancy old house that's falling apart at the seams, centering on a doctor in town and his increasing involvement with the house's residents and their troubles, which may or may not include being haunted. Waters has quite a way with the atmosphere and the characters--like I said, I was seriously creeped out. A.
