Slocum 356 - Slocum and Pearl of the Rio Grande

Slocum sticks his neck out for a woman wronged. 

When Slocum meets lovely young Perla, he learns that the New Mexican woman’s haughty manner masks fear. The Booster Brothers—rustlers who raped and robbed her, killed women and children, and murdered her husband—are leaving a trail of blood along the Rio Grande.
 
After Slocum agrees to escort Perla to her ranch, he takes another job —as avenging angel. But before he brings the gang to justice, Slocum finds you ride one hell of a road to carry out good intentions.
