A brand new adventure from Casey Nash and C. Wayne Winkle! Along the Guadalupe River, a rancher is losing cattle to a mysterious illness. A veterinarian from San Antonio is sent for. Upon his arrival he determines the cows are dying from Texas Fever. The question did the man who sold them the cows do so intentionally to introduce the sickness into their herd or was it an accident? One hundred and fifty miles north of the rancher’s homestead, the cattlemen of Waco, Texas are reeling from cattle losses of their own. Marshal Jubal Stone has ridden to two different ranches and seen the devastating effects of Texas Fever. Now it has shown up at the loading pens in town. Together the rancher, his family and Jubal Stone are now on the hunt for the man who is selling the tick-infested cattle across central Texas. Soon they’ll join forces to hunt the scoundrel and his partners who have quickly come to be known as Cattle Killers.
