Robert Harris’s diary: My accidental war with Tony Blair

To Paris, for the launch of the French edition of my novel about the Dreyfus affair. As we land, I isolate three anxieties out of my general sense of unease. First is the natural nervousness of any Englishman contemplating telling the French anything about their own country. Second is the French law which allows the descendants of actual historical figures — of whom there are dozens in my novel — to sue for defamation: the heirs of the Marquis de Sade even objected to an unflattering portrayal of the inventor of sadism.
