What is the theme in Gothic Literature by ?

Another theme is appearance and reality. Gothic literature often explores the muddy ground between appearance and reality. For example, in Radcliffe's works, events often appear to have supernatural causes. However, by the end of the book, Radcliffe offers realistic explanations. Thus, in the case of Radcliffe, it is possible for the reader to distinguish by the close of the novel what is real and what is apparent.
