'The Last Godfathers' by John Follain charts the history of the Corleonese mafia. Starts around the time of Mussolini and concludes early this year.
Brutal, high body count, but since it purports to be assembled from judicial documents, testimony, wiretaps etc etc, it seems to be a pretty together document of what was going on. Silvio Berlusconi plays his part, he saves the mafia from virtual annihilation - hmmmm.
Not usually my sort of book, found it on the tube.
