Author Stieg Larsson, the second biggest-selling novelist in the world in 2008 (behind Khaled Hosseini), left three-quarters of an unfinished book on his laptop when he died in 2004.

It was the fourth book in his posthumously published "Millennium" series of crime novels, which has already sold some 30 million copies worldwide. Larsson also reportedly left synopses for a fifth and sixth "Millennium" book. Fans of the series that began with 2005's "The Girl with the Dragon Tattoo" long to get their hands on anything more from the Swedish journalist and author.

Well, while I can't promise sex crimes, serial murder or shadowy corporations, this week I can tell of a nature mystery set outside the city of Skelleftea in northern Sweden, where Larsson was born. It involves DNA testing, a valuable gourmet prize, and a feisty young Japanese female researcher who helped discover it.
