I can't change overnight into a serious literary author. You can't compare apples to oranges. William Faulkner was a great literary genius. I am not.

More than 100 people have been sent to death row who were later exonerated because they weren't guilty or fairly tried. Most criminal defendants do not get adequate representation because there are not enough public defenders to represent them. There is a lot that is wrong.

Quite often I can be in a bookshop, standing beneath a great big picture of myself and paying for a book with a credit card clearly marked John Grisham, yet no one recognises me. I often say I'm a famous author in a country where no one reads.

And that's the mission of The Innocence Project in New York, is to exonerate people who have been wrongfully convicted, and also work from a policy angle with Congress and state legislatures to prevent future wrongful convictions.

I'm not itching to sue Amazon or Wal-Mart... they sell a lot of books. But the future is very uncertain with books.

I've had nine of my books adapted to film, and almost all were enjoyable. I've been very lucky with Hollywood, and look forward to more movies being adapted. But I don't get involved in that process. I know nothing about making movies and I stay away from it and hope for the best.

Nobody wants to read about the honest lawyer down the street who does real estate loans and wills. If you want to sell books, you have to write about the interesting lawyers - the guys who steal all the money and take off. That's the fun stuff.

Every morning I wake at 6am or 6.30am, champing at the bit.

I don't want to force my politics on my readers.
