The Haunting of Hill House - Shirley Jackson

The Legend of Hell House - Richard Matheson

Ghosts - Noel Hynd

City of Masks - Daniel Hecht

The first two are well-known but I don't think I've ever seen anyone mention the Noel Hynd book. I picked it up one day in a store when I was needing a book while on a roadtrip and didn't see anything else that caught my attention. It's a story about a haunting set on Nantucket Island.

City of Masks is set in New Orleans and is sort of a psychological thriller as well as a horror story.
