The first book in the Millennium trilogy “The Girl with the Dragon Tattoo” describes the investigation led by Mikael Bloomkvist (journalist) and Elizabeth Salander (computer hacker) to resolve the 40 year old mystery of a missing 16 year old girl - Harriet Vanger - from a family owned island in Sweden. The novel is a pretty easy read, gripping and a great thriller.
By the way, the book is much more interesting than the movie. The movie just misses on many details which enrich the overall storyline.

“Being a homicide detective can be the loneliest job in the world. The friends of the victim are upset and in despair, but sooner or later after weeks or months they go back to their everyday lives. For the closest family it takes longer, but for the most part, to some degree, they too get over their grieving and despair. Life has to go on; it does go on. But the unsolved murders keep gnawing away and in the end there’s only one person left who thinks night and day about the victim: it’s the officer who’s left with the investigation.”
“I've had many enemies over the years. If there is one thing I've learned, it's never engage in a fight you're sure to lose. On the other hand, never let anyone who has insulted you get away with it. Bide you're time and strike back when you're in a position of strength - even if you no longer need to strike back.”
“Friendship - is built on two things. Respect and trust. Both elements have to be there. And it has to be mutual. You can have respect for someone, but if you don't have trust, the friendship will crumble.”
