9pm, BBC Four
As the curtain rises on the finale of Clive Bradley’s attractively sombre Scandi-noir, the killer is getting bolder by the minute and tracking them down becomes not just a matter of public safety but a personal vendetta. Now Andri races to get Thorhildur to safety in the wake of her confession, but is dispatching her to Reykjavík by road the best solution? And, more importantly, does the killer know what vital clues she has given to Ásgeir? Gradually the pieces of the puzzle fall into place, and toxic politics cost more lives. Mike Bradley
The Voice UK
The singing contest trundles dutifully towards the end of its pre-recorded section, with acts surviving the knockouts tonight and next week going through, at last, to the live shows. A task of such import requires guest mentors: Anne-Marie, James Arthur, Olly Alexander and Nicole Scherzinger step in. Jack Seale
Teddy Pendergrass: If You Don’t Know Me
9pm, Sky Arts
A well-illustrated portrait of soul star Teddy Pendergrass, who went from drummer to lead singer with Harold Melvin & the Blue Notes (as if that wasn’t enough) and on to enjoy a solo career epitomised by the unforgettable Love TKO but interrupted by a life-changing accident in 1982. MB
Africa’s Great Civilisations

The Queen Mum: The Lost Year
9.30pm, Channel 5
This week, the the generic but informative series explores the aftermath of the death of George VI. Dealing with grief and loss of status, the Queen Mother somehow adjusted to life in “small, horrid” new gaff Clarence House and made a different role for herself. Phil Harrison
Sicario, 10.25pm, Channel 4
The gruesome opening here, in which the FBI uncover a literal house of the dead, points up the brutal nature of Denis Villeneuve’s thriller about the US war on drugs. One of the FBI team, Emma Blunt’s tenacious Kate, is drafted into a murky covert op in Mexico, led by the brash James Brolin. Paul Howlett
