He knows that he must leave the magazine for some period of time. But Blomkist’s predicament is an opportunity for Henrik Vanger, an aging, retired head of a vast Swedish business empire, to renew his forty year obsession with unraveling the mystery of the disappearance of his brother’s grand-daughter Harriet from the family’s remote island compound. As Blomkist later discovers, it is Salander who does an amazingly detailed background check on him before he is hired by Henrik. As Blomkist burrows down into the evidence maintained all these years, as well as grasping the extent of the dysfunctionality of the entire Vanger clan, he realizes he needs a research assistant. Who’s better than Lisbeth Salander?
