Reddit mentions of The Postman Always Rings Twice

I assume you're mostly looking for novels, right?

You might know Antoine de Saint-Exupery as the author of The Little Prince, but he was also one of the pioneering pilots of the early days of airmail, and wrote several short novels about flying. My favorite is Flight to Arras, but Night Flight is also worth checking out.

I've recommended Thornton Wilder's The Bridge of San Luis Rey so many times that I'm surprised I haven't developed a reputation, but it's along similar lines, and well worth the read.

If you're into books that depict the darker side of life, there are a lot of great shorter books in roman noir and roman dur territory. Check out James Cain's Double Indemnity and The Postman Always Rings Twice, or Georges Simenon's Tropic Moon.
