What are your thoughts on The Fall by Albert Camus?
Here are some resources on it I would like to share with you:
(rare BBC documentary)
(a lecture about The Plague and The Fall. He starts talking about The Fall about halfway through.)
(continuation of the previous lecture, entirely dedicated to The Fall.)
The Plague is a far better-written book while still containing a fair amount of symbolic substance. I can personally relate to The Fall more, but that's not the point.
The Plague is also better written than The Stranger, by quite a ways.
