From the back cover: "Longarm wasn't the kind of guy who liked to play by the rules. Especially the rules of baseball, a sissy game if he ever saw one. But someone is following a traveling baseball team around the country--and robbing local post offices while the townspeople are watching the game. The only way Longarm can investigate without looking like a lawman is by looking like a baseball player--and playing like one, too. He knows he's good at throwing punches and running roughshod--but is Longarm sharp enough to catch a ball while trying to catch a thief?"
