I read Razor's Edge in high school. I'd have to refresh my memory on it, but Maugham had a wry fascination for the darker side of human nature.
Hero With a Thousand Faces .. seen excerpts over the years. Might there have been a PBS series based on it? I seem to remember seeing JC extensively interviewed... Didn't read the entire book, though.
Interesting that you are putting the two together: what is your thinking there?
