I was born in 1956 in Stanmore, Middlesex, to a family of wealth and status. I was raised by nannies and surrounded by servants and chauffeurs.
I was a very unhappy and overweight child. I was sent away to boarding school when I was just 8 and I hated every minute of it. Once the headmaster told me to stand up in assembly and in front of the whole school said, 'This boy is so stupid he will not be coming to Christmas games tomorrow.' I have never totally recovered. To relieve my misery and that of the other boys, I made up tales of astounding revenge.
My unhappy childhood gave me a gift — it provided me with rich source material for all my books. All the nasty experiences inspired me to write! Also I was able to escape from my horrible school life through the James Bond films. Alex Rider is very like a young James Bond.
I started to make up stories so I could escape the real world.
As well as writing books I write scripts for TV series such as Foyle's War and Midsomer Murders so I am very busy! I write for 10 hours a day in a small studio at the bottom of my garden.
As I said as a kid I loved James Bond but I also loved Charles Dickens. I often think that my unhappy childhood and life at boarding school was very much like one of his books. Great Expectations is my favourite.
I spent lots of time daydreaming about being a secret agent and this was the first inspiration for the series. Then when writing it I did lots of research, for instance I actually went in a car crusher and up a crane for Stormbreaker.
Probably the one when the headmaster called me stupid.
My passion is scuba-diving. I have dived all over the world, including the South China Sea where I saw hammerhead sharks.
Believe in yourself. It's not easy getting started and there'll always be someone to tell you you're not going to succeed. They're wrong. The only difference between a successful writer and an unsuccessful writer is that the unsuccessful writer gives up.
