Harriet Vanger's disappearance from Hedeby Island
In 1966 sixteen-year-old Harriet Vanger vanished from Hedeby Island while a traffic accident blocked the only bridge, sealing the family inside. For forty years her great-uncle Henrik received a pressed flower every birthday and assumed her killer was a relative. Blomkvist and Salander found that her brother Martin had continued their father Gottfried's serial murders of women, and that Harriet was not dead: she had fled to Australia and was living there under her cousin Anita's name.
