When my first novel was published, I went in great excitement round bookshops in central London to see if they had stocked it.

The great European dream was to diminish militant nationalism. We would all be happy Europeans together. But we are going to see the old monster of militant nationalism being awoken when people realise how little control their politicians have.

The British bombing of Caen beginning on D-Day in particular was stupid, counter-productive and above all very close to a war crime.

It was only after five years in the army, when I was having to do a very boring job in a very boring place, that I thought: 'Why not try writing a novel?' partly out of youthful arrogance and partly because there had been a long line of writers in my mother's family.

When I was younger I used to get my best writing done at night, but now it has to be during the day. I usually finish work at half past seven, then go back to the house to open a bottle of wine, have dinner, and then read or watch television.

I think it's outrageous if a historian has a 'leading thought' because it means they will select their material according to their thesis

I just love the days when you come out of the archives with half a dozen excellent descriptions or poignant accounts of personal experiences.

Few things reveal more about political leaders and their systems than the manner of their downfall.
