Keith of the Border

'Keith of the Border' is a western adventure fiction written by Randall Parrish. Parrish wrote popular potboilers and historical novels and was trained as a lawyer; he spent time as an attorney, and many years as a newspaper journalist, with a stint as a railroad worker and sheep driver in between. His experience on the road from Las Vegas and Albuquerque informed his Western romance writing style.
Excerpt:
"The man was riding just below the summit of the ridge, occasionally uplifting his head so as to gaze across the crest, shading his eyes with one hand to thus better concentrate his vision. Both horse and rider plainly exhibited signs of weariness, but every movement of the latter showed ceaseless vigilance, his glance roaming the barren ridges, a brown Winchester lying cocked across the saddle pommel, his left hand taut on the rein. Yet the horse he bestrode scarcely required restraint, advancing slowly, with head hanging low, and only occasionally breaking into a brief trot under the impetus of the spur."
