Sweden's Most Puzzling Nonfiction Murder Mystery: Who Killed Prime Minister Olof Palme? And Who Was His Unlikely Assassin? A talk in English by Swedish journalist Hans Hederberg. Presenting his new book, the speaker draws two in-depth profiles, the first on Palme himself and the second on Christer Pettersson – here in plain terms called “the perpetrator.” (Only the formalities of the Swedish legal system kept him from being condemned, believes Hederberg.) Plowing through hearings and investigations, this journalist was the first outsider to get access to the presumed assassin's classified mental health studies. -- "The best thing that has been written about the Palme murder... In all likelihood Christer Pettersson was the killer and all the other leads led nowhere or were dead ends." -- Håkan Arvidsson, on the Danish TV program "Lorry," March 2, 2011,
