At a certain age, apparently, it’s well known that women give up on trying to beautify their bodies and get to work on improving their houses instead. No longer is it Vogue and Grazia cluttering the coffee table, but Living Etc and Elle Decor, laid out in a tidy fan. No longer does one venture out in body-con dresses, but nests instead at home, in an animal-look onesie, snuggled on the sofa with this or that box set. All that effort that used to go on fretting about one’s outfit has to go somewhere. So is it the quality of the writing that’s the best thing about Danish television at the moment, or is it the interior design? I wrote here about the utopian symbolism – as I saw it – of all those beautiful, glowing and planetary Danish light-fittings in The Killing, my previous box-set project. And I’ve been delighted to see all the classics – the Artichoke, the Enigma, the Henningsen PH4 – out in force in my new favourite, Borgen, the second run of which begins this evening on BBC4. This is the one in which Birgitte Nyborg, the middle-aged and middle-class leader of the exceedingly middle-of-the-road 'Moderate Party', unexpectedly finds herself the first female prime minister of Denmark. The stirring credit sequence shows her bounding off her bike from her domestic life and into the public sphere, leaving her kids behind in her elegant house with her handsome husband to stride the corridors of the Folketinget, smiling her captivatingly crinkle-nostrilled smile. 'It’s a chess game, if you like,' the veteran correspondent Hanne Holm says about Danish electoral politics at the beginning of the first episode. Certainly one of the programme’s many pleasures is second-guessing Nyborg on her increasingly raptor-like calculations as she fires people and forms various weird-looking and fragile coalitions.

We didn’t start watching The Killing in my house until long after everybody else did – at the beginning of this year, I think, when somebody gave us the box set of the first series. By that time I was a bit bored of Sara Lund and her famous jumper – she wears it far too small and clingy, in my view. The trophy knit of the moment should hang from the shoulders, big and square. But I did love the women’s hairdos, mouse-brown and tied back on a good day, left out lank and mournful on the many bad. I couldn’t even tell who was who to begin with, they were all so ordinary in their jeans and parkas, groping through tears and the Danish darkness, nodding and saying hej and tak.
