Stieg Larsson was born in Skelleftehamn, Västerbottens län, Sweden, the son of Erland Larsson (born 1935) and his wife Vivianne, née Boström (1937–1991). By March 2015, his series had sold 80 million copies worldwide. The third and final novel in the Millennium trilogy, The Girl Who Kicked the Hornets' Nest, became the bestselling book in the United States in 2010, according to Publishers Weekly. He was the second-best-selling fiction author in the world for 2008, owing to the success of the English translation of The Girl with the Dragon Tattoo, behind the Afghan-American Khaled Hosseini. His journalistic work covered socialist politics and he acted as an independent researcher of right-wing extremism. For much of his life, Larsson lived and worked in Stockholm. The publisher commissioned David Lagercrantz to expand the trilogy into a longer series, which has six novels as of September 2019. The trilogy was adapted as three motion pictures in Sweden, and one in the U.S. He is best known for writing the Millennium trilogy of crime novels, which were published posthumously, starting in 2005, after he died of a sudden heart attack.
