The Lone Gun — Howard Rigsby

The night he broke jail her should have put spurs to the bay's flanks, and driven her without heed or mercy until she dropped beneath him -- or until he reached the border.

But instead took to the hills, armed with just his gun and his stubborn resolution. From here he lay high in the rocks he could see the lights of the town spread out beneath him. In it were a girl named Mary Silk and killer freely walking the streets.

The first he loved. And around the next of the second Brooks Cameron meant to put the hangman's noose.
