I've been reading Leonardo Sciascia's The Moro Affair, for the second time, and finding it just as disturbing as the first time, though perhaps for new reasons.
I first read Sciascia's work when I heard about The Day of the Owl, a crime novel. A police-procedural, in fact, that knocked the usual police-procedural into a cocked hat. When published in 1961, I gather, it had some impact in Italy because it dramatised the connection between the Mafia and the Christian-Democrat (DC) government. Sciascia, a Sicilian who became one of Italy's major public intellectuals, wrote several other superb crime novels with a philosophical and political edge, a range of other books, plays, and a lot of political journalism. In the 1970s he was elected to the Italian parliament on the Communist (PCI) ticket, but left the party in disgust when its leaders proposed their 'historic compromise' with the corrupt Christian Democrat regime.
