The Icelandic thriller returns for a second series, while Jed Mercurio’s adaptation of DH Lawrence’s novel gets a welcome reairing

Trapped

9pm, BBC Four

A second series of the Icelandic thriller opens with an attack on the minister of industries outside the parliament in Reykjavík. A suspected link to far-right nationalists prompts the police to dispatch detective Andri Olafsson to his northern home town to investigate. With his family life still disrupted following the dark events of three years ago, he is apprehensive about returning to a cold reception in the remote fastness, where fascism festers and murders soon begin to multiply. Some gaping holes in the plot but compelling overall. Mike Bradley

Trapped – the Icelandic thriller that's the unexpected TV hit of the year so far

The Greatest Dancer

7.35pm, BBC One

For those sticking with the hoofing show, it’s now time for the last live challenge. With only six acts left and a couple of weeks to go, the standard is high, even though there have been some glorious acts ditched so far. Tonight the captains must guide their teams to pull out a performance that will keep them in the game. Hannah Verdier

Great British Car Journeys

8pm, Channel 4

In the last in the series, All Creatures Great and Small stars Christopher Timothy and Peter Davison reunite for a picturesque trip from Cardiff to Snowdonia in a vintage Morgan 4/4. This is a journey of personal discovery for Timothy, born in Wales but not overly acquainted with the country. David Stubbs

Spending Secrets of the Royals

9pm, Channel 5

Have the royals become an expensive burden, asks the second film in this awestruck two-parter. The answer, of course, is yes, but it’s been that way since time immemorial. As aides wheel out “70% approval ratings” it seems we are fated to remain subjects not citizens for a while longer. MB

Lady Chatterley's Lover: no sex please, we're on British TV

Lady Chatterley’s Lover

9pm, Drama

Jed “Bodyguard” Mercurio’s 2015 adaptation of DH Lawrence’s novel may be less than brilliant, but what makes it worth a reappraisal is that it features a young cast destined for great things. Starring here are Richard Madden, James Norton, Holliday Grainger and Jodie Comer. MB

Mayans MC

10.45pm, BBC Two

Double bill of Kurt Sutter’s Sons of Anarchy spin-off, which continues to simmer menacingly. Angel has a new business partner with big plans for his stolen heroin. He introduces himself by leaving a head on a spike in Angel’s front room, so he’s not to be trifled with. Elsewhere, Alvarez’s search for the rat continues. Phil Harrison

The Lime,y 2.15am, AMC From BT

Terence Stamp is the Limey, a British ex-con heading to LA to investigate the death of his daughter, who was mixed up with a rock music producer (Peter Fonda); it’s great to see these icons going head to head. With its wry humour and existential air, this was described by Steven Soderbergh as Get Carter made by Alain Resnais. Paul Howlett
