Query: BEST Book of Mafia History

This was the absolutely best book I have ever read of Mafia history. It was well written and even though it was 708 pages I read through it with interest and vigor. I got the book from the library but I definitely will buy it. If you are a mafia enthusiast this is the book to have in your library. Selwyn Raab did an EXCELLENT job!
