So in case you're also concerned about that, and it has kept you from continuing with the series, this is not something you should worry about. Since the story lasted as many pages as it did, you are just as happy with the ending as Lisbeth ought to be. You've deserved it, having rooted for her for so long. However, I now think there's a more ulterior motive to Larsson's crime fiction.
I think he wrote all this to make a case for the importance of media, and the necessity of integrity in journalism, police work and even the government. He hangs a thrilling crime and courtroom drama off it, but almost every character and every vignette has a little teachable lesson in it. Case in point: Erika Berger's off-camera difficulties in this final book. Perhaps I'm slow, and this was obvious from the get-go, but I'm okay with it taking me that many pages to understand. It was that many pages to enjoy reading.
