What to watch
The Bridge BBC TWO, 9.00PM
With the exception perhaps of Wallander, of all the Scandi-noir characters that we’ve seen in recent years it is The Bridge’s Saga Norén (Sofia Helin), a committed Malmö detective with a level of social dysfunction that implies autism, who has burrowed deepest into the hearts of UK viewers. She struggles to cope emotionally with the world around her, but that only makes us like her all the more. When last we saw Saga, at the close of series three two years ago, she had solved another major murder case but stood accused herself of killing her abusive mother. At least she had the consolation of meeting a soulmate of sorts in Henrik Sabroe (Thure Lindhardt), a police colleague from across the Øresund bridge linking Sweden and Denmark, and a man deeply damaged by the murder of his wife and the disappearance of his two young daughters.
At the start of this instantly gripping fourth and final series, things are not looking good for Saga as she wakes up in a cold, grey, unfamiliar environment. Meanwhile, Henrik is called to the scene of a particularly grizzly murder in Copenhagen that has a link to the controversial deportation of an Iranian illegal immigrant.
