I don’t know if anyone here has seen the Danish series “The Investigation” a couple of years back. Really excellent series. It was about the investigation into the “submarine murder” of Kim Wall, a really terrible case. In the series, they focused solely on the investigation itself, and the impact on the victim’s family, and not on the murderer at all. In fact, the murderer was not featured on screen and was not even named (he was only referred to as “the perpetrator”, etc). It was an unusual way to approach this sort of drama and quite refreshing, as too often IMO true life dramas feed into a kind of weird fetish about murderers. Anyway it’s well worth a watch if you’ve not seen it.
