The House of Dr. Edwardes is a psychological thriller novel written by John Palmer and Hilary A. Saunders under the pseudonym Francis Beeding.
The plot concerns an asylum that is about to get a new director. The new man is knocked unconscious and imprisoned by an imposter who allows patients—including a satanist planning a human sacrifice—to run amuck.
The novel was adapted to film in 1945 as Alfred Hitchcock's Spellbound. The film uses the idea of an imposter and some character names, but otherwise bears no resemblance to the novel.
