Lisbeth Salander
Larsson stated in interviews that he based many characters, including that of Lisbeth Salander, on characters from Astrid Lindgren novels. Blomkvist is frequently referred to by his colleagues in the news media as "Kalle Blomkvist", a reference to a boy detective who appears in several of Lindgren's novels, because his first notable investigation is uncovering the hideout of a gang of bank robbers. Lisbeth Salander sarcastically refers to him by this nickname throughout the series.
