Abstract: Prelude to Christopher, a novel written by Eleanor Dark in 1930s, has won her great reputation and admiration.Commented as a "brave book", this book requires multiple perspectives to get to its core.As two of the many themes involved, feminism and insanity are well merged and articulated enough in the book to arouse many controversies among critics.This thesis tries to analyze the feminist Dark and her concern with the relationship between madness and freedom.
