The Premature Burial (1962)

Set in the early dark Victorian-era 1830s or '40s (also similar to Charles Dickens' fiction of rain-soaked London streets), it follows Guy Carrell, who is obssessed with the fear of death. He is most obssessed with the fear of his being buried alive. Though his fiancee Emily says he has nothing to be afriad of, he still thinks he will be buried alive (a common fear and in reality an occasional occurrence with the primitive and happen-stance character of the practice of early surgical and medicine science then, with bodies being raided from morgues to do educational autopsies and witch potions being prescribed for all sorts of miscellaneous ailments and the yet-to-be-discovered theories by Pasteur and Lister of germs and bacteria thus preventing infections). So deluded, he seeks help from a few people, including his sister, but he still is haunted by the fear of death and the sense that someone close wants him dead.
