Read the Girl with the Dragon Tatoo quite a while ago...It was the only one of Larsson's three books that I found to be decent, a good thriller, but after the first one, it was all down hill....A lot of artificiality, writing style/translation, I don't know, they left me talking to myself about writers selling out...
As to Dan Brown, I think I speed read it, it was bad, bad, bad. He should stick to teaching or back to school and take some writing classes...
One of my all time favorites - mystery/thriller genre - is from John Le Carre...His first one, called Call for the Dead...He is right at the top of the list for cold war spy stories....I reread my favorites from him once a year. Him and Jane Austen...Now that's a duo....
