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 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.
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.
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.
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.

In every war zone that I've been in, there has been a reality and then there has been the public perception of why the war was being fought. In every crisis, the issues have been far more complex than the public has been allowed to know.
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 think I'm in the same mood as ever, but in some ways more mature. I guess you could say that, at 65, when you've seen the world shape up as I have, there are only two things you can do: laugh or kill yourself.
People who've had very unhappy childhoods are pretty good at inventing themselves. If nobody invents you for yourself, nothing is left but to invent yourself for others.
If I had to put a name to it, I would wish that all my books were entertainments. I think the first thing you've got to do is grab the reader by the ear, and make him sit down and listen. Make him laugh, make him feel. We all want to be entertained at a very high level.
