I'll start - I love The High Window by Raymond Chandler. In fact, I love all Raymond Chandler's books as he was the inspiration for mine. I haven't seen many noir films though, hence the question, so would love some reccommendations
Just about anything by James Ellroy. I particularly enjoyed the Underworld USA Trilogy of American Tabloid (1995), The Cold Six Thousand (2001) & Blood's a Rover (2009) - innovative and compelling writing.
L.A. Confidential (1990) is the best of the book-to-film Ellroy's (despite the changes).
