Query: Laws of the Heart

Robert Parker's "Appaloosa" was not just about two Marshals upholding the law in the old west. It was also about respect and friendship between two men and what happens to that friendship when a fickle woman steals the heart of one of the Marshals. Parker's no-nonsense dialog and understanding of human nature was so refreshing I have bought and read another of his books!
