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.

Benedict Allen gives you the impression that he hasn't done any research at all, and I am sure he has. And when he is off doing his ice dogs and that sort of thing - and therefore its not only an exploration of the place but also his imagination in a sense. It's very successful as technique.

Radio is very popular [in Britain], but it doesn't connect us in the same way. It seems to have this community function.

When McDonald's opened up in Moscow - I happened to be there when it opened and wandered in. And the Russians were queuing three times around the block to get in. And when they got to the head of the queue, they'd go, "I'll have a Big Mac please. Have you the cheese and the rolls? And do you have the meat and do you have the salad?" And everybody asks this because they are so used to things being awful that it took them a quarter of an hour to order a Big Mac.

I wonder if this reason is partly geographical, that talk radio is so much more successful in North America than in Britain? People who are very remote - I'm thinking of Newfoundland - feel very connected though the radio.

What's fascinating is where they come from in the world. People in Bangladesh, a chap in a fire-base in Tikrit in Iraq. Chap in an Irish pub in Dublin. And lovely to think this literary network - or rather network of readers - is well spread out.

There is a very big difference between American and British travel journalism, and that's this whole business of the assisted or freebie trip. In Britain we are unashamed about any travel company paying for you to go and then writing about it. That's the only way we can do it. But I have tried the same in the States, and I can't write for any sizeable American newspaper because they tell you to do it on this basis.
