I was amused to see "The Outsider" and "The Stranger" as two books by Albert Camus, though "The Outsider" seems to link to novels by Colin Wilson and Stephen King. "L'Étranger" is a good book and not too hard to read in French because it's written in a colloquial style, or you could read one of the many translations: at least four just in English. There are a lot of books in that list that I liked so I should probably pay some attention to the ones that I haven't yet looked at.
