This book also starts out slow with Mikael Blomkvist considering publishing an expose on sex trafficking. We also follow Lisbeth Salander as she travels around the world, she came into money at the end of the last book.
Shortly before the article is ready to go to print, the two people responsible for bringing the story to Blomkvist and doing the research on it are murdered and Salander is implicated.
Blomkvist is convinced Salander is innocent and starts his own investigation, he also continues working on the expose, convinced that this is the reason for the murders.
Everything that happens is tied to Salander’s past, which is revealed to us in cryptic flash backs by Salander and then in a narrative from an old friend. Blomkvist and Salander both track down the guilty party through different means.
What I like about this book is it continues Salander’s story, what happens that is connected to the previous book stays true to what happened. The characters stay true to themselves which gives continuity to the writing.
