Warlock by Oakley Hall. A Western novel about the town of Warlock and it's a very good example of revisionist western: where characters are shades of moral grey instead of classic old west good vs. Bad.
The writing though does a lot of effort to make dialogs appear old-timey (was written in 1958) and characters will often go around to beat some desert bush, making some conversations dreadful.
Regardless, a solid recommendation for anyone with a western itch.
