Eva Gabrielsson spent 32 years of her life as the girlfriend, partner, and journalistic colleague of late Swedish novelist Stieg Larsson, whose Millennium trilogy — The Girl With The Dragon Tattoo, The Girl Who Played With Fire, The Girl Who Woke The Hornet’s Nest — sold 60 million copies world-wide. (Larsson died in 2004, at the age of 50.) She has recently written the memoir “There Are Things I Want You To Know” About Stieg Larsson and Me, where she writes about both mundane events in their decades together and his life-long investigative crusade against the extremist right-wing groups who managed to survive — and sometimes, thrive — in the winter paradises of Scandinavia. The issues that he wrote about came into stark relief last month in Oslo, Norway, when an unknown extremist named Anders Breivik set off a bomb in the middle of Oslo and then took a boat over to an island summer camp nearby for young members of the center-left Labor party, where he gunned down more than 60 children and teenagers. I spoke with Gabrielsson by phone last Thursday. An edited transcript is below.

You first met Stieg as young journalists, and both of you focused most of your journalistic energy on extremist right-wing and fascist groups in Scandinavia. How do Breivik’s beliefs and actions fit in with those political currents?
