I started to write in 2001. I wrote the books for the fun of it. It was an old idea I had had since the nineties.
I will write a couple of books and become a millionaire.
I have been threatened occasionally. But that happens to everybody who is writing this kind of things. Threats will come without fail. It might happen to the most 'innocent' texts. If it gets too much we call the police.
Writing detective stories is about writing light literature, for entertainment. It isn't primarily a question of writing propaganda or classical literature.
I'm a fast writer, and crime novels are easy to do. It's much harder to write a 1,000 word article, where everything has to be 100 per cent correct.
