This is a fun book. Great for summer reading. If you enjoy stories about mobsters, bank robbers and the FBI in the thirties you'll love this book. I have to confess that he talks a lot about guns - in detail. I tried to stay with those passages but I just don't know anything about guns, so I got a little lost once or twice. I finally just skipped those paragraphs when they started. It didn't have any effect on my enjoyment of the story.
