Tom Mix Western #45

The issue contains two stories: "The Secret Letter," in which Tom Mix must protect a secret letter while danger and death pursue him across the plains, and "Black Jack," a Fightin' Forbes story by Walter Farmer set in the rough town of Brimstone, where Forbes confronts gambling corruption at the Last Chance Casino and must deal with a dangerous criminal wielding a blackjack. In the Tom Mix story, his wonder horse Tony helps him escape pursuers by responding to a whistle, while Mix takes refuge in a house where he must evade both Ponce and his henchmen who seek to force him to give up the letter.
