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.

beware of your most implacable enemy-yourself.

I grew up in Rhodesia on my father's ranch and every year he used to take us on safari in some remote area of the wilderness.

I think one of the most poignant things is unrequited love and loneliness.

Usually halfway through a book I have a serious depression, so I go on safari on my ranch in South Africa, or fishing off my island in the Seychelles. When I come back and re-read it, I think: 'What was all that about, Smith? It's fine, just get on with it.'

My family wasn't terribly affluent and looked upon money very carefully as something that had to be saved, not spent. My father built the ducting that took air into the copper mines and made about 6 d a yard in the Thirties, which was good money back then.

I have never had too much trouble for creative ideas to spring up in my mind.
