You know that feeling when you finish a final exam and you think, 'I never want to do that again'? Well I have the same feeling when I finish a novel. Each time I say, 'I think I may retire now' and then after six months the ideas start to churn again. I could never stop.

I'm not a good father and they're not children any more; the eldest is in his fifties. My relationship with their mothers broke down and, because of what the law was, they went with their mothers and were imbued with their mothers' morality in life and they were not my people any more.

Politicians all over the world cater to domestic vote banks. They will spend only on what their constituents want.

A man follows the path laid out for him. He does his duty to God and his King. He does what he must do, not what pleases him. God's truth, boy, what kind of world would this be if every man did what pleased him alone? Who would plough the fields and reap the harvest, if every man had the right to say, 'I don't want to do that.' In this world there is a place for every man, but every man must know his place.
