Kurdo Baksi, who wrote My friend Stieg Larsson last year, said the author had more books in the pipeline, a Swedish newspaper reported.
Baksi told the Expressen the fourth book in the series was set on Banks Island, a remote island off the west coast of Canada, and features Camilla, who was last seen briefly in the second novel The Girl Who Played With Fire . The deepening relationship between Salander and investigative journalist Mikael Blomqvist would also be explored.
Baksi said Larsson had completed the introduction and finale to the fourth, untitled, book.
It has been widely reported that Larsson had planned to write up to six books in the Millennium Series.
Murdoch Books distributes the series in Australia.
