Many people have compared me to the Victorian adventure writer, Rider Haggard. I accept that as a compliment. As a boy growing up in Central Africa I read all Haggard's African novels.

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.

I work on my novels wherever I have a PC, and I have four or five places around the world where I do have a PC. These days you can just slip a little flash drive into your top pocket, fly for 12 hours, come to another place, plug it into a computer and you are away again.

This first print run of the first edition of my first novel, 'When The Lion Feeds.' back in 1964, is so rare it can fetch several thousand pounds at auction. I always wanted to be an author, and I decided to write about what I knew.
