I thought that this book is great for anyone who wishes to gain a better understanding of the Chicago Mafia, organized crime, and law enforcement in general. When people think of the Mafia, they tend to lean towards New York as "the model". Little do they know that Chicago, commonly referred to as the "Second City", has a serious history, and are forces to be reckoned with. Bill Roemer Jr. tells all in this book, from an FBI agent's point view of course. He weaves a web of important players in the Chicago Outfit, with chilling accounts from characters such as Tony Accardo aka "Joe Batters", the outfit's most respected and feared leader/counselor. The inside scoop on Sam Giancana, Joey Aiuppa, and Joe Ferriola a few of the many Mob Bosses depicted. A must read chilling chapter on "Mad" Sam DeStefano will leave the insides of your stomach churning! You will see how Tony Spilotro(the cover boy)fits into the scheme of things, and after reading this book and watching CASINO, you will see how the two resemble each other almost identically, scary!! Pick this book up.
