In a letter to the science fiction magazine, Larsson said the stories were his first try at writing. He also said that he aspired to be an author and journalist.
Larsson died of a sudden heart attack in 2004 at the age of 50. The novelist died before he got to see his three crime novels, which feature a prickly, pierced, computer hacker heroine, become successful. The author had originally planned to write 10 books for the series. The novels were made into successful Swedish films and are currently being made into Hollywood films.
