A compelling and psychologically dense attempt to unravel a crime that shook a nation at its core

The Swedish five part limited series is a fictional interpretation of the murder of Prime Minister Olof Palme in 1986 based on the the award-winning book The Unlikely Murderer from 2018 written by Thomas Pettersson.

The story is especially concerned with Stig Engström, the graphic designer who was named as the probable murderer, and how he managed to elude justice right up to his death through a combination of audacity, luck and a perplexed police force. Robert Gustafsson (The Hundred-Year-Old Man Who Climbed Out of the Window and Disappeared, Det som göms i snö), one of Sweden’s most beloved comedians and actors, will play the lead role as Stig Engström. Gustafsson has said that: “It’s an exciting challenge and a great responsibility to portray Stig Engström, but also, in a way, a form of therapy. Since I was at the same cinema as Olof Palme on the night of the murder, this case has always felt like an abscess that never disappears – and I’m not alone in feeling that.’

As such, the drama series deals with a past that has settled as a national trauma within the Swedish people. The story explores questions like what makes someone a murderer and who feels compelled to target a prime minister for assassination? And finally, how did this sad, solipsistic figure of Stig Engström elude police detection?

Join scriptwriters Wilhelm Berhmann and Niklas Rockström (Caliphate, Before We Die) for a talk about The Unlikely Murderer, a prominent Swedish contribution to the Nordic Noir scene and possibly, the greatest real-life whodunit in Swedish history.
