George Offerman Jr.

The smartest deck-hand (card deck that is) in the West -- Bat Masterson -- is about to be gunned down during a game, when trigger- happy Ben Thompson saves his life. Thompson, wounded in the affray, is unable to carry out his intention to help his brother Billy break jail. However, Bat's gratitude comes in good stead for Ben and his brother.

Morganville's bully-boy, Dan Morgan - to his great misfortune - cheats Bat in a poker game. Bat executes a bold plan to retrieve his money: He discovers the names of Morgan's other victims - and sets out to settle scores for them as well as for himself.
