In 1970 Pasolini bought an old castle near Viterbo , several miles north of Rome , where he began to write his last novel , '' Il Petrolio '' , where he denounced obscure dealing in the highest levels of government and the corporate world ( Eni , CIA , the Mafia , etc. ) . The novel-documentary was left incomplete at his death . In 1972 , Pasolini started to collaborate with the extreme-left association Lotta Continua , producing a documentary , '' 12 dicembre '' , concerning the Piazza Fontana bombing . The following year he began a collaboration for Italy 's most renowned newspaper , '' Il Corriere della Sera '' . At the beginning of 1975 Garzanti published a collection of his critical essays , '' Scritti corsari '' ( " Corsair Writings " )
