Another installment to late Swedish author Stieg Larsson's highly successful Millennium crime trilogy will go on sale in at least 35 countries from August, a report published on The Guardian quoted the book's publishers as saying.

That Which Does Not Kill was completed in November by David Lagercrantz. He stands in for Larsson, who died of a heart attack in 2004.

The book will continue the story of damaged protagonist Lisbeth Salander who became famous with the first book in the series 'The Girl with the Dragon Tattoo'.

However, the author refused to divulge the meaning of the book's title or what direction the 500 pages long novel in Swedish will take.

“What I wanted to make use of in the book was the vast mythology that Stieg Larsson left behind, the world he created,” Lagercrantz told Swedish newspaper Dagens Nyheter, adding that he remained loyal to Larsson’s writing style which weaved criticism of social and political issues with criminal intrigue.

“Lisbeth Salander’s not just any superhero. She’s not only great because of her talents but also because of her context and background.”

At the time of his death Stieg Larsson reportedly had plans to write at least another seven novels.
