I blush easily. I have difficulty meeting people's eye, difficulty with public speaking, the normal afflictions of the shy, but not to a paralysing degree.

I did not know that the planning for biological and chemical warfare was so widespread in England, and even in France before France fell. It was news to me that there had been talk, even in the First World War, of dropping Colorado beetles on German potato crops and that kind of thing.

What's somewhat puzzling is that Churchill himself knew what the reaction would be to any sort of aerial attack on cities, because in 1938 he said that in a future war British cities would be attacked by bombing, and that the response would be that all men would want to join the fight because they would be so incensed by this cowardly manner of attack. Which is a very natural response: when something drops on you from the air and blows up a bunch of buildings and kills people in their sleep, the reaction is going to be rage, confusion, and a search for something to destroy in retaliation.

There's something paralyzing about being a writer that you have to escape. I don't want to think of myself as a guy who's written a bunch of books. The 26 letters distance us from our own hesitations and they make us sound as if we know what we're doing. We know grammar, we know prose, but actually we're all just struggling in the dark, really.

As soon as you start doing that - changing things - it seems self-evident to me that you've entered the world of make-believe. If you pretend that it's true, and use your own name, you are misleading people. Fiction is looser and wilder and sometimes in the end more self-revealing, anyway.

Churchill was a brilliant and inspiring rhetorician, but one of the first things he did as the head of the British nation was to put German Jews in jail. Tens of thousands of Jews - who had just been fortunate enough to get out from under Hitler only a few years before - spent the entire war in jail.

I would like to visit the factory that makes train horns, and ask them how they are able to arrive at that chord of eternal mournfulness. Is it deliberately sad? Are the horns saying, Be careful, stay away from this train or it will run you over and then people will grieve, and their grief will be as the inconsolable wail of this horn through the night? The out-of-tuneness of the triad is part of its beauty.
