Tex lived with his father on their ranch in Whisperin' Valley, near Wishbone, Texas. One day the head of the "Cattlemen's Protection League" attempted to extort protection money from Tex's father. His father refused and the head of the League rode off, threatening the man.
Tex joined the Army during the Civil War. While away in the Unior Army at war, Tex received a letter saying that his father had been killed and that he had sold the ranch to the League before his demise.
Tex returned to find that the head of the League had rigged an election and became Sheriff, afterwards forcing Tex's father to sign the ranch over to him, and then had him killed. Tex investigated matters and discovered that the town mayor was responsible for everything. The mayor was interested in the gold deposits on the ranch of Tex's father. Tex killed the mayor, and then vowed to spend his life hunting criminals all over the west and destroying them.
