John le Carre

If you're growing up in a chaotic world without reason, your instinct is to become a performer and control the circumstances around you. You lead from weakness into strength; you have an undefended back.

I've always had difficulties with female characters.

When I was 16 or 17, anyone could have had me if they sang the right song and recruited me in the right way. Which is why I've always had a sneaking understanding for people who took the wrong route. That doesn't mean to say I took it or even contemplated it myself.

I wrote 'The Spy Who Came in from the Cold' at the age of 30 under intense, unshared personal stress and in extreme privacy. As an intelligence officer in the guise of a junior diplomat at the British Embassy in Bonn, I was a secret to my colleagues, and much of the time to myself.

I've had nothing to do with the intelligence world since I left it, in any shade or variety.

SIS, the Secret Intelligence Service, also known as MI6, also has no executive powers and operates abroad on CIA lines, but with a tiny percentage of the budget and a tiny percentage of the personnel.

It's necessary to understand what real intelligence work is. It will never cease. It's absolutely essential that we have it. At its best, it is simply the left arm of healthy governmental curiosity. It brings to a strong government what it needs to know. It's the collection of information, a journalistic job, if you will, but done in secret.

It's part of a writer's profession, as it's part of a spy's profession, to prey on the community to which he's attached, to take away information - often in secret - and to translate that into intelligence for his masters, whether it's his readership or his spy masters. And I think that both professions are perhaps rather lonely.

The Secret Intelligence Service I knew occupied dusky suites of little rooms opposite St James's Park Tube station in London.

For better or worse, I've been involved in the description of political conflict.

I want to be like Ford Madox Ford. I want to be talking to somebody across a fire, and I want him to join me and listen to me, and if he is fidgeting in his chair, I know I am not doing my job. I am a storyteller, and I know most people like a story.

In my day, MI6 - which I called the Circus in the books - stank of wartime nostalgia. People were defined by secret cachet: one man did something absolutely extraordinary in Norway; another was the darling of the French Resistance. We didn't even show passes to go in and out of the building.
