At the age of 15, Larsson witnessed the gang rape of a young girl, leaving him understandably disgusted by sexual violence. The experience haunted him for the rest of his life, and he never forgave himself for failing to help the girl. The victim's name was Lisbeth - which is the origin of the name he gave the young heroine of the trilogy, herself a rape victim. This memory was the inspiration for the theme of sexual violence against women in his books.
Lisbeth Salander and Mikael Blomkvist are the primary characters in the series. Lisbeth, a woman in her twenties is an intelligent, eccentric, and possessing of a photographic memory. Blomkvist is an investigative journalist, a celebrity in his own right, whose history somewhat similar to Larsson's own.
About three-quarters of a fourth novel was written by Larsson before his sudden and unexpected death in November 2004. His partner, Eva Gabrielsson, is in possession of Larsson's notebook computer containing the manuscript; unconfirmed outlines or manuscripts written by the original author for one or two more books may still exist.
- 2005: The Girl with the Dragon Tattoo, original title Män som hatar kvinnor (In English: Men Who Hate Women)
- 2006: The Girl Who Played with Fire, original title Flickan som lekte med elden. (In English: The Girl Who Played with Fire)
- 2007: The Girl Who Kicked the Hornets' Nest, original title Luftslottet som sprängdes. (In English: The Air Castle That Exploded -- while the literal translation may not make much sense in English, Luftslott -meaning "air castle" is an expression equivalent to our "pipe dream," that being an impossible or far-fetched dream. Thus "The Air Castle That Was Blown Up" comes to refer to an impossible dream that was ruined or destroyed)
According to Charles McGrath's New York Times article "The Afterlife of Stieg Larsson", approximately 27 million copies have been sold worldwide as of May 2010.
