THIS WORLD The Mafia’s Secret Bunkers. Italy’s most powerful organised crime group is no longer Sicily’s Cosa Nostra but the ‘Ndrangheta’, a shadowy Mafia from the southern region of Calabria. With unique access to the extraordinary underground bunkers the gangsters use for hiding out and to the hi-tech war being fought by the Italian authorities against this murderous criminal brotherhood, author and mafia historian John Dickie uncovers the truth about Europe’s biggest cocaine traffickers. This is a world of special forces, spy planes and super grasses, as well as a culture of fear and silence where people simply do not trust the Italian state to defeat the Mafiosi.
