When Swedish journalist Kim Wall went missing in 2017 after boarding a submarine to interview its eccentric designer Peter Madsen, it became an international sensation. Now an addictive six-episode series from Oscar-nominated director and writer Tobias Lindholm dramatizes the search for Wall and the truth, in HBO’sThe Investigation. Created in close collaboration with the victim’s parents, Joachim and Ingrid Wall, and Jens Møller, former head of homicide for the Copenhagen police,the show is told from the perspective of the officers as they painstakingly unfurl the truth. It’s a thriller, but of the psychological sort; Lindholm takes his sweet time revealing each new detail, allowing viewers to ruminate over every scene, and reminding them that the search for the truth is rarely linear or efficient. —Ashley Baker
