Long ridin' man

the long version

"They call him 'Hunter' because he ruthlessly picks off men. But there is one man in particular for whom he searches: the man who destroyed his family. Catching up with the killer finds Hunter in a booming town in urgent need of a deputy sheriff and, in need of cash, he pins on the badge. But the body count is rising and the folk of Cimarron wonder just who they've hired as their peacemaker and when Hunter discovers why the town needs a fast gun so urgently the odds are that it will be too late for him to get out alive..." --Publisher description.
