This one is a really well done Scandinavian detective movie. I think it is better than "The Girl with the Dragon Tattoo". Successful and there are a few moments that made plot twists but i am used to it. I think it is not difficult to think that Gunnar is traitor and Nete has changed her identity. Department Q series is generally moderate when considering the scenario and plot but with this they had achieved their level. The best one is this film in this series and 1>3>2
