Good news, fans of the "Millennium" series, the much-debated existence of another book has been confirmed. Stieg Larsson's brother Joakim, in an interview with CBS, said that days before Stieg's death, the author confirmed another manuscript was almost complete. "I got an e-mail from Stieg 10 days before he died, where he said that book four is nearly finished," Joakim said in the interview. There's a twist though: "To make it more complicated, this book No. 4 -- that's book No. 5, because he thought that was more fun to write." Larsson died of a heart attack in 2004, and never lived to see "The Girl With the Dragon Tattoo," "The Girl Who Played with Fire," or "The Girl Who Kicked the Hornet's Nest," become published. Larsson reportedly intended for there to be 10 books in the series. A spokesperson for the books' publisher, Knopf, told The New York Times that he believed the unpublished manuscript existed, but did not know whether it was intended to be a the fourth book or the fifth.
