You should have died when I killed you.

A committee is an animal with four back legs.

Writing is like walking in a deserted street. Out of the dust in the street you make a mud pie.

Having your book turned into a movie is like seeing your oxen turned into bouillon cubes.

A desk is a dangerous place from which to view the world.

History keeps her secrets longer than most of us. But she has one secret that I will reveal to you tonight in the greatest confidence. Sometimes there are no winners at all. And sometimes nobody needs to lose.

Fools, most linguists. Damn all to say in one language, so they learn another and say damn all in that.

You should have died when I killed you.

The monsters of our childhood do not fade away, neither are they ever wholly monstrous. But neither, in my experience, do we ever reach a plane of detachment regarding our parents, however wise and old we may become. To pretend otherwise is to cheat.

Love is whatever you can still betray. Betrayal can only happen if you love.

If there is one eternal truth of politics, it is that there are always a dozen good reasons for doing nothing.

'The Spy Who Came in from the Cold' was the work of a wayward imagination brought to the end of its tether by political disgust and personal confusion.

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.

But there is a big difference in working for the West and working for a totalitarian state.

Completing a book, it's a little like having a baby.

I began writing when I was still in the British Foreign Service, and it was then understood that even if you wrote about butterfly collecting, you used another name.

I do believe very much in movie as a one-man-show. I think that where I've watched movie go wrong, it's usually because the dread committee has been interfering with it.

I grew up in a completely bookless household. It was my father's boast that he had never read a book from end to end.

I grew up in a completely bookless household. It was my father's boast that he had never read a book from end to end. I don't remember any of his ladies being bookish. So I was entirely dependent on my schoolteachers for my early reading with the exception of 'The Wind in the Willows,' which a stepmother read to me when I was in hospital.

I made an awful mess of my first marriage. It was hard to live with me being me. I was so abnormal. I mean, most writers struggle. I hadn't struggled. I couldn't suddenly go down to the PEN Club and behave like a normal human being, because most of those guys were struggling to make a couple of thousand pounds a year.

I mean, I'm in the business of storytelling, not message making.

I remain terrified of the capacity of the media, the capacity of spin doctors, here and abroad, particularly the United States media, to perpetuate false lies, perpetuate lies.

I suffer from the same frustration that every decent American suffers from. That is, that you begin to wonder whether decent liberal instincts, decent humanitarian instincts, can actually penetrate the right-wing voice, get through the steering of American opinion by the mass media.

I taught principally German language and literature at Eton. But any master with private pupils must be prepared to teach anything they ask for. That can be as diverse as the early paintings of Salvador Dali or how bumblebees manage to fly.

I think bankers will always get away with whatever they can get away with.

I think, increasingly, despite what we are being told is an ever more open world of communication, there is a terrible alienation in the ordinary man between what he is being told and what he secretly believes.

I was quite able at the insignificant work I did in MI6, but absolutely dysfunctional in my domestic life. I had no experience of fatherhood. I had no example of marital bliss or the family unit.

I worked for MI6 in the Sixties, during the great witch-hunts, when the shared paranoia of the Cold War gripped the services.

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.

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.

It is my writing dilemma. The world of spying is my genre. My struggle is to demystify, to de-romanticise the spook world, but at the same time harness it as a good story.

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.

Like every novelist, I fantasise about film. Novelists are not equipped to make a movie, in my opinion. They make their own movie when they write: they're casting, they're dressing the scene, they're working out where the energy of the scene is coming from, and they're also relying tremendously on the creative imagination of the reader.

More particularly, having a largely German-oriented education has made me very responsive to 19th-century German literature.

My definition of a decent society is one that first of all takes care of its losers, and protects its weak.

Once you've lived the inside-out world of espionage, you never shed it. It's a mentality, a double standard of existence.

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

The creation of George Smiley, the retired spy recalled to hunt for just such a high-ranking mole in 'Tinker, Tailor,' was extremely personal. I borrowed elements of people I admired and invested them in this mythical character. I'm such a fluent, specious person now, but I was an extremely awkward fellow in those days.

The world of spying is my genre. My struggle is to demystify, to de-romanticise the spook world, but at the same time harness it as a good story.

To give the best of the day to your work is most important.

Totalitarian states killed with impunity and no one was held accountable. That didn't happen in the West.

Well, certainly I don't think that there are very many good writers who don't live without a sense of tension. If they haven't got one immediately available to them, then they usually manage to manufacture it in their private lives.

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.

When you are brought up as a frozen child, you go on freezing. It wasn't until I had my four sons, who have brought me immense joy, that I began to thaw. That I realised how utterly extraordinary my childhood was.

Writers are two-home men - they want a place outside and a place within.

You have no idea how humiliating it was, as a boy, to suddenly have all your clothes, your toys, snatched by the bailiff. I mean we were a middle-class family, it's not as if it was happening up and down the street. It made me ashamed, I felt dirty.

Aviation is proof that given, the will, we have the capacity to achieve the impossible.
