„Valley of the Vanishing Men” begins with Ben Trainor receiving a letter from home that tells him that his brother who was bound for Alkali Valley has been missing. Alkali Valley was a lawless desert outpost, known for its gunplay and gold. Ben Trainor rode into town searching for his vanished brother. Within twenty-four hours he had been slugged, shot at, and bushwhacked. „"Go home while you’re still in one piece"” the sheriff advised him. But Ben decided to stick it out. And when his friend Silvertip slipped into town to help him out, it was just the two of them against a pack of gun-happy killers. Two men against a gang of killers!
