Once a Ranger - Cattle Kill (en Inglés) - Robert Kammen

For Guy Jarrett it was the terrible agony of not knowing if Reba Jo or the rest of them were still alive. A few missing cattle could be explained away, a man misplacing some saddle gear, and sometimes lonely cowhands riding their broncs into sinkholes and never seen again. But a trail herd of some two thousand cattle just up and vanishing along with the men bringing them up from Texas? And all a man had to go on was a letter postmarked out of Sheridan, Wyoming.

A former Texas Ranger turned rancher, Guy heads out looking for his brother and the woman he loves. What he uncovers is a band of ruthless outlaws who will stop at nothing, including murder, to gain the riches they want.
