DRAMA

LOOKING BACK Roger, John, Simon and Nick BBC4, 9pm

ICONIC British rock band Duran Duran take over BBC4 tonight with two brand-new documentaries that give a rare insight into the megastars.

BBC2, 9pm

It’s time for the relentless darkness to end.

This is the last-ever episode of this Nordic noir, and hopefully fans will feel it ties up loose ends.

There is a murderer on the loose, of course, as well as someone leaking details of the investigation to the press, so viewers will be hoping to find out their identities.

The homeless girls, who have met with psychologist Niels Thormod, now know who the killer is. They try to get in contact with Henrik (Thure Lindhardt), but at the same time the killer is looking for them, leading the girls to run for their lives.

Meanwhile, Saga (Sofia Helin) finds a match for the killer’s fingerprint and is on the trail.

But just as everything seems to have fallen into place and the case is finally solved, there is one little detail that changes everything.

A haunting farewell to a bleak and gripping series.
