Longarm and the Golden Ghost — Tabor Evans

Longarm goes gunning for a spectral Spaniard!

As a favor to the Texas Rangers, Deputy U.S. Marshal Custis Long goes undercover in the hell-raising West Texas town of Tascosa. What he finds is a do-nothing sheriff, a pair of seductive sirens, and a range war that's about to get bloody.
 
But the locals are far more afraid of something else -- a glowing ghost in golden conquistador armor. Whenever he appears, someone dies. And there's no telling who's next. Longarm has to uncover the truth behind the lethal apparition, before someone sends him into the next world -- with a bullet in his back.
