Shakespeare’s modern-day champion Kenneth Branagh (right) returns for a fourth and final season as Swedish detective Kurt Wallander, with the first of the last three episodes taking him to South Africa. He’s in the country for a conference, but before you know it, he’s distracted by the case of a Swedish woman who has gone missing in Cape Town. As usual, the determined Wallander won’t rest until he gets to the bottom of things, no matter how emotional the journey gets. English-language remakes of Scandi dramas don’t always work well, but this one has been a real treat, largely thanks to Branagh’s intense portrayal of the ageing sleuth.
