There are plenty of books available, fiction, nonfiction, and well-researched fiction.

My favorite line comes from New York news reporter Jimmy Breslin.

He said that in the Godfather movie you had one hotheaded shooter, one coldblooded thinker, and one dirty, yellow rat bastard. In the real Mafia, you've got fifty Sonnys, five Michaels, and 10,000 Fredos.
