I read all of Rider Haggard's books. For me he had the romance of Africa with a little bit of mysticism. I'm delighted to be looked on as his heir and be categorised as an adventure novelist because that's exactly what I am.

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.'

I go on a hunting safari at least once a year to Botswana, which is fantastic because we have a huge area of wilderness entirely to ourselves. My island covers roughly 55 acres, which again I have to myself, with nearly half a kilometre of private beach with my own jetties and boats.

Politicians all over the world cater to domestic vote banks. They will spend only on what their constituents want. So unless there is a grass root green movement in a nation the politicians will not be willing to spend money on curbing emissions. More awareness is needed amongst the people to effect the real change in how governments spend.

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.

There's nothing so aphrodisiacal for a woman as money and success.

Every time one of my books sells a million copies in paperback, Pan Macmillan gives me a gold statuette of Pan. I have about 20 of them.
