The final book in the Millennium trilogy continues the story from book two. It ties up many of the loose ends, documents Lisbeth's fight in the courts, and provides closure on a few topics. However, it does this by inventing the clichéd freemason-like secret department within the secret service. This department, apparently very powerful, is also populated by idiots and the plot fails completely because of this.
But, if you liked books one and two, you can consider this book the longest epilogue ever written and enjoy it for that reason. Disappointing.
