The fact that you can only do a little is no excuse for doing nothing.

I've never been able to write a book without one very strong character in my rucksack.

But I think the real tension lies in the relationship between what you might call the pursuer and his quarry, whether it's the writer or the spy.

A good writer is an expert on nothing except himself. And on that subject, if he is wise, he holds his tongue.

How Bush and his junta succeeded in deflecting America's anger from bin Laden to Saddam Hussein is one of the great public relations conjuring tricks of history. But they swung it. A recent poll tells us that one in two Americans now believe Saddam was responsible for the attack on the World Trade Centre.

I think that most of my books are part of some process of self-education, often about the places I go to. Most of all, they are about the peculiar tension between institutional loyalty and loyalty to oneself; the mystery of patriotism, for a Brit of my age and generation, where it runs, how it should be defined, what it's worth and what a corrupting force it can be when misapplied. All that stuff is just in me and it comes out in the characters. I don't mean to preach, but I know I do, and I'm a very flawed person. It's quite ridiculous.

Look... we're getting to be old men, and we've spent our lives looking for the weaknesses in one another's systems. I can see through Eastern values just as you can see through our Western ones. Both of us, I am sure, have experienced ad nauseam the technical satisfactions of this wretched war. But now your own side is going to shoot you. Don't you think it's time to recognise that there is as little worth on your side as there is on mine?
