Books like Albert Camus's The Stranger

I came across this while browsing the 800s in my local library and thought, "why not?" because The Stranger is a book I still reread regularly. It offers brief, interesting insights but nothing I haven't already come across before in other books. There are references to several texts I'd like to follow up with though: "The Makropulos Case: Reflections on the Tedium of Immortality" from Problems of the Self by Bernard Williams, Karel Capek's The Makropulos Case, and "L'Etranger and 'Metaphysical Anxiety' by Frantz Favre.
