I read book one of the Stieg Larssen trilogy...and couldn't wait to read the other two!

The Girl With the Dragon Tattoo, The Girl Who Played With Fire, and The Girl Who Kicked the Hornet's Nest.

There were supposed to be 10 of these books. Sadly, Larssen died shortly after handing the first three in to his publisher. He died of a heart attack at age 50.

Half of the fourth one is still in his computer; you can read about the legal situation holding this up if you look him up on Wikipedia and other sites.
