Query: The Best Haunted House Novel Ever

Easily the best haunted house novel ever written. Hill House, with its history of one tragedy after another, is described by Mrs. Jackson as "insane". Even its angles and corners do not meet right. Its floors are infinitesimally off balance, making a sense of subconscious unease come upon anyone who enters. When a parapsychologist assembles a team to spend a few days in Hill House, no one foresees what is to come. Do not look for boogy men here, the menace is much less obvious than that. This is horror for the sensitive and intelligent reader. PS Unlike Ghost Story, feel free to see the original (not the 1990's remake) of the film version of this book.
