Prior to his sudden death of a heart attack in November 2004, Stieg Larsson finished three detective novels in his Millenium series. Before his career as a writer, Stieg Larsson was mostly known for his struggle against racism and right-wing extremism. In the middle of the 1980s he helped start the anti-violence project Stop the Racism. This was followed by the founding of the Expo foundation in 1995. In 1999 he was appointed the chief editor of Expo, a magazine published by the organization.
