The book was cleverly plotted and it was fun to watch all the investigations come together. Also I got some insight into the way jounalists work -- although perhaps not those who work at the Sun and other UK tabloids.
There are rumors that Larsson had started a fourth book before he died. There is still the mystery of Salander's sister. Also, perhaps there could be a little cyber warfare against Sweden. Anyway I am done after reading three.
Well, perhaps I should watch all the films (from Sweden and not the planned crappy Hollywood remakes) now..
