Finished Season 3 of Unforgotten. Excellent series. For me, ranks up there with No Offence, Vera, Balthazar, Shetland and Trapped as my favorite foreign mystery shows. The acting and story were great. I particularly liked that, unlike so many other shows, there was almost no depiction of violence. I did not have to cover my eyes during any gory stuff.
ETA: Started watching River last night on Amazon Prime. Unusual British police drama - 1 season, 6 episodes. Well done so far.
