Unless you fancy dying in a symbolic and grisly fashion, you don't cross a Camorra member, let alone all of them in one go. So rather than celebrating the fact that his book has already sold nearly two million copies in more than 40 countries, and that its City of God-style film adaptation won the Grand Prix at Cannes this year, 'vigilante journalist' Roberto Saviano is in hiding after numerous threats that he will be dead by Christmas. His exposé of the Neapolitan mafia is unprecendently intimate, thanks to a period undercover working in their factories and building sites, participating in their commercial operations and witnessing their merciless and arbitrary murders. The sheer number of families, businesses and killings is almost overwhelming, but the most startling thing is Saviano's courage.
