This final volume can be considered the "day of reckoning" on the events that have transpired in M1 and M2. A silent but omnipresent actor enters the stage, the Government, in the form of the Section for Special Analysis (SSA) (p. 82), Säpo's autonomous top secret division, run by some die hard Cold Warriors. Since misinformation is the basis of espionage (p. 144), the author succeeds in building a very complex dialogue - the reader is typically prepped on reality and can see the misinformation propagate. M3 showcases true storytelling mastery. Larsson is making a bigger statement here, related to the constitutional rights of LS and the crime against her for which the State is guilty (p. 279). The SSA is acting outside it's constitutional mandate (p. 281) in a conspiracy. Many readers complain of the protracted discussions of these human rights issues, but Larsson is choosing to use his crime thriller to make a case.
Fröken Salander is a poster girl for injustice. Larsson, a self proclaimed feminist makes the case again and again that women have been victimized for, shall we say. Millennia ? As a preface to M3, he posts a little piece about Amazon women (p. 147) and the etymology of the word "Amazon." Later he references the Fon of Dahomey, a women's army in west Africa, finally defeated in 1892.
