The 2017 gruesome murder of young Swedish journalist Kim Wall is now being documented for the screen in HBO's upcoming fictional adaptation, 'The Investigation'. Originally released in September 2020, on the Danish network TV 2 | Danmark A/S, the Scandinavian thriller is based on a worldwide phenomenon that was dubbed "the submarine case" by the media. The show brings back the very detested Euron Greyjoy from 'Game of Thrones' aka Pilou Asbaek, who incidentally enough plays the good guy here.

Release date

Dropping hot to usher the next month in, 'The Investigation' premiers this Monday, February 1, at 10 pm only on HBO.


The limited drama series "follows the team of investigators and divers who worked tirelessly for six months in the face of seemingly insurmountable obstacles to gather evidence and bring justice for Wall’s family," reveals the official HBO synopsis.

True story

Three years ago, Wall had boarded the midget submarine UC3 Nautilus, in Køge Bugt, Denmark, to interview owner, Danish entrepreneur Peter Madsen. Soon after the Nautilus failed to return to Refshaleøen, Copenhagen, she was reported missing. Later, the submarine was found sunken on August 11, 2017, and Madsen was rescued and immediately arrested. Through August and November 2017, Wall's dismembered body parts were found scattered around the area with several knife wounds, mostly in the groin area. Madsen was convicted for her murder and sentenced to life imprisonment on 25 April by Copenhagen City Court after a widely publicized trial. In 2020, there was an alleged prison break attempt, that went unsuccessful.



The cast is lead by Søren Malling ('A Hijacking') as Jens Møller, the Head of Homicide for the Copenhagen Police. Asbæk plays prosecutor Jakob Buch-Jepsen. Pernilla August ('Star Wars') and Rolf Lassgård ('The Hunters') star as Kim Wall’s parents, Ingrid and Joachim Wall.

The series is written, directed and executive produced by Oscar-Nominated Tobias Lindholm whom you might know for his acclaimed work in creating another phenomenon of the true-crime genre – 'Mindhunter'. Fremantle’s Scandinavian production company, Miso Film produces the show, with real-life cop Jens Møller and Kim Wall’s parents, Ingrid and Joachim actively contributing to the narrative.



This is the beauteous part of the entire series so far. Picking up right after the tragedy has stuck, the trailer sees Jens sail through the essence of strong Nordic noir prevalent in the murder mystery that had socked the media at the time. Check it out for yourself right here.
