I find the public reaction to writing - it's fascinating in this modern age. Of course people are able to interact with me and email me, and I get quite a few I suppose.

There is a whole genre of funny travel writers - that's very popular. There's Bill Bryson and people who follow that route and sell travel writing through making people laugh. It's a very difficult group to take. The line between comedy and mockery is sometimes a bit thin.

I have a nice little idea from some people I met there who are now in their seventies, and I want to tell their story about the revolution through the eyes of musicians, in fact. The '59 Revolution. And what has happened to them since. It's very much a Cuban story. They haven't fared too well.

The United Nations was the thing I wanted to work for. Like the United Nations Commission for Refugees is what I was interested in. And then people said if you do that you'll hit glass ceilings all the time, because you are not Ghanian or Nigerian and that's the way to progress though a multinational organization like that. In any event, they said do five years' legal experience and come back. And after five years I decided to stay where I was. So I am really an accidental lawyer.

I don't want to sell other people trips! I want to be there!

I wouldn't like to see Cuba change in other ways. And the trouble is when Fidel [Castro] does go - I am sure he will at some stage. He will probably be replaced by some sort of Western capitalism, ultimately.

I have to be careful not to visit one place right after the other and write one book after the other. Because I fear writing the same book all over again. That's why I am taking a break and doing something different this time.
