They (the publishers) would be ecstatic, I just refuse to. You can't repeat a great act.

I wanted it (the book) to set my cop a very difficult task, which is to find out `whodunit' without any of the modern aids of DNA testing and the like.

I lived in the US for donkeys' years so it has been a journey back in time for me. If you have had personal experience of something, it is always more authentic.

It is one of the biggest, best sellers of all time.

There is no doubt that it is more difficult to read and more difficult to write but I still manage.

It means I don't have much depth of vision.
