ANYTHING by Ralph Cotton. He is a lesser-known older western writer, but "Hangman's Choice" is in my top 5 fav books of all time in any genre. I couldn't put it down!! Jurisdiction is also super good. And Black Mesa is probably the third. All by him. I just can't get enough. Sadly, some of his older works, like the ones listed, are out of print. Maybe the library will have them, if not Amazon
is always a safe bet. Seriously, tho, read Hangman's Choice.
