I met a lot of hackers, and some of them were very arrogant. They thought I was stupid because I couldn't follow what they were talking about. But then I met this great guy whom companies hire to find their security holes, and he was very good about explaining so I could understand.

All great characters, great icons, in literature are a bit of a riddle, and that's the reason we go back to them over and over.

I'm a strange kind of author - I like assignments. I wasn't clever enough to invent an iconic figure like Salander, but she's my kind of girl.

I want to have new challenges and write new crazy books because I think it makes me a better writer to be insecure and try new things.

There is no money in the world that would compensate me for writing a lousy book.

I want to be read, and I certainly want to sell, but I also see my father's eye from Heaven: 'Always write quality. It doesn't matter if you sell; if it's good, it's good - if you capture the complexity of life.'

I'm not a secretive guy. I'm talkative.

The capacity of computers is doubling every eight months. It's exponential development. I think it's a real threat, actually, that a computer one day will be more intelligent than us.

We must fight intolerance, racism and the far-Right.

I'm ashamed to say that I'm from a very privileged background.

The beautiful thing is I have sort of grown up. I don't care if I'm highbrow or not anymore.

Alan Turing is such an amazing, tragic story.

I said from the start I had to be trustful of the Millennium universe. It was not going to be a Stieg Larsson book, but my interpretation of his iconic characters and universe.

Part of the brilliance of Stieg Larsson's books is that they are so complex, so many different facets coming together.

We had all these famous writers in Sweden and from all over the world home at dinner. I wanted to be a writer, and I wanted to be a highbrow writer as my father. He never, ever read anything like crime novels. He wrote biographies of Dante, James Joyce, August Strindberg and Joseph Conrad.

I've always been interested in people who think out of their time, and I have this passion, actually, for science. I'm just so enormously interested in how, when you think of these revolutionary ideas, other people get threatened, especially if you are different.

I'm always interested in talented or odd people, and my whole life I've written about geniuses who society has treated badly and they strike back - or not.

I have this reporter's temperament still in me - I thrive under pressure.

I was so obsessed by Lisbeth Salander and all the characters, but of course if you're going to write a crime novel worthy of Stieg Larsson, you need a plot, don't you?

You have to search for the best writer - I'm not saying I'm the one, but it's a bad idea to just find the person who is a copycat of Stieg Larsson.

A supervillain must continue to exist.

I'm an author who likes assignments, who needs suggestions, ideas I would never have thought of otherwise - then something happens inside my alien head. Other people have to decide whether or not I'm a good writer, but I do have the ability to write in different styles.

I wrote about Alan Turing, the great mathematician and code-breaker. He was an absolutely different person, certainly more brilliant than I ever will be.

The real demon in my life is my father.

Of course I want to be a best seller because I'm in the business and I want to be read, but there is no money in the world that can compensate for writing badly.
