Good rogue sub yarn. Irving A. Greenfield's novel is about a submarine called the Barracuda. It's captained by an ultra-patriot who sees commies everywhere. One of the first ships the submarine attacks is a ship called the African Wolf. The captain thinks that the United States and the Soviet Union are at war so he decides to attack what he perceives to be enemy shipping. He's supposed to be participating in war games but he's taken them too far. Read this book to find out more.
