Appaloosa by Robert B Parker

When Virgil Cole and Everett Hitch arrive in Appaloosa, they find a town suffering at the hands of a renegade rancher who’s already left the city marshal and one of his deputies dead. Cole and Hitch are used to cleaning up after scavengers, but this one raises the stakes by playing not with the rules—but with emotion.

This book has several editions so the cover may look different than the pic. Also there is another Appaloosa book by Robert Parker...not the book we are discussing.

Also adapted into a movie starring Viggo Mortensen, Ed Harris, and Rene Zellweger.
