Devil in a Blue Dress by Walter Mosley, book and movie. I read the first in the Easy Rawlins books set in a black neighborhood of 1940s LA several years ago. Yesterday, I watched the movie version for the first time. I really enjoyed the movie because the cast is superb. As I watched the movie, I thought about how much has changed in 70 years and how much has not. I recommend both the movie and the book highly.
