When Stieg Larsson died, the author of The Girl with the Dragon Tattoo had been working on a true mystery that out-twisted his Millennium novels: the assassination on February 28, 1986, of Olof Palme, the Swedish prime minister. It was the first time in history that a head of state had been murdered without a clue who had done it, and on a Stockholm street at point-blank range. Internationally known for his fictional far-right villains, Larsson was well acquainted with their real-life counterparts and documented extremist activities throughout the world. Larsson's archive was forgotten until journalist Jan Stocklassa was given exclusive access to the author's secret project. Stocklassa collects the pieces of Larsson's true-crime puzzle to follow the trail of intrigue, espionage, and conspiracy begun by one of the world's most famous thriller writers. Together they set out to solve a mystery that no one else could.
