"Ben Travis, owner of the Triple X, was dead on his own front porch, and his nephew, Hugh Travis, started west to investigate. In his pocket he carried a letter from Charles Waller, his friend and attorney - a mysterious letter which spoke of danger and a deadly feud. Tucson offered Hugh a suspicious welcome, for it was a frontier town clamped in the vice of a range war. On one side were the independent cattlemen, and on the other the Caldwell clan led by big Morg Caldwell and his gunman, Bump Fleagle. And there was Katherine Caldwell, whose fiery emotions were torn between family loyalty and her attraction to the new owner of the Triple X. With the wisdom and the .45 of Dad Arnold, his trusted foreman, Hugh almost succeeded in bringing peace to Apache Basin. Then without warning the new dam was dynamited, a small child drowned, and Hugh found the Caldwells meeting him more than halfway - with guns in their hands. But only one man was a real killer. Hidden in the dense woods, Hugh heard the man's voice taunting him to a final showdown. It was the end of the trail and Hugh knew he must ignore all caution and accept the challenge to danger"--,Provided by publisher.
