The Fighting Yank #17

The Fighting Yank must stop a gang of criminals led by Count Roska who have stolen atomic bombs and hidden them in the Midwest, demanding a billion dollars in jewels and cash as ransom. When the gang plans to detonate the bombs, the Fighting Yank enlists private detectives and the U.S. Army to recover the explosives, leading to a chase sequence involving a woman connected to the criminals and a climactic effort to prevent the atomic threat from being carried out.
