I never expected to write a book about a slum in Ireland that was going to catapult me, as they say, into some kind of - onto the best seller list.

A lot of people say writers start losing their powers after 60 or 65. But I look at the best-seller list and see a book by that 14-year-old gymnast, Dominique Moceanu, and I think, 'Now, what's she going to tell the world? And these 25-year-old rock stars, what are they going to tell the world?'

First of all there is always that artistic challenge of creating something. Or the particular experience to take slum life in that period and make something out of it in the form of a book. And then I felt some kind of responsibility to my family.

There was a kind of madness in the country. Eamon De Valera, the prime minister, had this vision of an Ireland where we'd all be in some kind of native costume - which doesn't exist - and we'd be dancing at the crossroads, babbling away in Gaelic, going to Mass, everyone virginal and pure.

It isn't what they say about you, it's what they whisper.

Don't trust everyone, especially if they say, 'Trust me.'
