Well I think after leaving prison, and having written three diaries about life in prison, it became a sort of a new challenge to write another novel, to write a new novel.
But the thing I felt most strongly about, and put at the end of one of the prison diaries, was education.
I think my attitude to human beings has changed since leaving prison.
Sixty per cent of people entering prison today are illiterate.
Well I certainly have learned and I hope I'm moving on and certainly two years of prison was a terrible punishment.
I wrote a million words in the first year, and I could never have done that outside of prison.
And I did wonder - because it's now three years ago since I left prison - whether there would come a time when I would forget it, or it would be in the past as anything else might be - no, it's there every day of my life.
But I certainly made mistakes, for which I regret, I think most human beings in their lifetime make mistakes, mine ended up in two years prison - two very remarkable years from which I learnt a lot.
