I Know Who You Are
9pm, BBC4
Back after its gratuitously scheduled cliffhanger hiatus, the Spanish psychological drama picks up where it left off – mild spoilers ahead for those still catching up via iPlayer – with an episode that finds Alicia injured and unconscious. But who attacked her and why? Will Ana ever find freedom? And the show’s perennial question: just what really motivates charismatic lawyer Juan Elias? Tense and unpredictable, one of the year’s TV highlights. Jonathan Wright
Josh Widdicombe: What Do I Do Now
9pm, BBC2
The Last Leg’s cross, mop-topped comic Josh Widdicombe expresses his fizzing irritation with a hefty number of things in his most recent standup show at the Hammersmith Apollo. Among the items receiving his frustrated ire are his overflowing shower tray, contactless debit cards, his childhood cabin bed and people who ask him to bring back things from his holidays. As he quite rightly points out, he’s going on holiday, not doing a big shop. Ben Arnold
Gunpowder
9.10pm, BBC1
Those brave, sexy “Cath-hollicks” get a heroic sendoff as the hilariously tabloid-baiting drama concludes. The last stand of Robert Catesby (Kit Harington) and his bros at Holbeche House is, most notably, converted from a mildly comical capitulation to a full action-movie glory death, with both swords and guns blazing for ages. In between are more of those satisfyingly realistic scenes of execution, torture (tonight: fingernails) and unwavering refusals to recant. Jack Seale
NCIS: New Orleans
10pm, Channel 5
Less gung-ho, more gumbo: the most enjoyable offshoot of the NCIS procedural juggernaut kicks off its third season with a minor cast reshuffle. Scott Bakula returns as leonine agent-in-charge Dwayne Pride but his right-hand woman Brody has jumped ship. Elsewhere, this opening double bill features a multi-agency hunt for a sniper and a cameo by Tom Arnold as a dodgy hacker called Elvis who is, inevitably, caught in a trap. Graeme Virtue
The Jonathan Ross Show
10.05pm, ITV
Ross has a satisfying lineup this week, with a mix of Hollywood, music and home-grown talent. In the Oscar-winning corner is Jodie Foster, who could be interesting for some post-Weinstein comments. David Walliams works his charm and Roisin Conaty, the rising star of Man Down and GameFace, brings the laughs. Purveyor of fine tunes and stories Debbie Harry drops in for a chat and provides the music with Blondie. Hannah Verdier
Maritime Silk Road Reborn
7pm, National Geographic
With enthusiastic maritime historian Sam Willis as our guide, this series tracks the 15,000km of China’s ancient trading route from the port of Guangzhou, through south-east Asia and the piratical Malacca Straits, to India. The fascinating first leg features 15th-century wooden “treasure ships” as long as a football pitch and eight storeys high, in fleets of 200, and the singular cultural and religious mix that is Malacca City today. Sharon O’Connell
Leonard Cohen: I’m Your Man
7pm, Sky Arts
You want it darker, Leonard Cohen’s swansong suggested, as 2016 began lowering the drapes; the “death of a ladies’ man” this time last year capping that grim 12 months. In this 2005 tribute concert (to a still-living Len – which seems like a wry joke he would have appreciated), Nick Cave, Rufus Wainwright and others pay homage, reminding us that where Cohen went there was always (gallows) laughter, zen-like pragmatism and kindness. Ali Catterall
TV films
Unknown, (Jaume Collet-Serra, 2011), 11.10pm, Channel 4
Liam Neeson’s scientist awakens from a coma after a car smash and no one, including his wife (January Jones), appears to know who he is – and mysterious killers are after him. Neeson makes a slightly more vulnerable American abroad than in his Taken films, in a smart and suspenseful conspiracy thriller. Paul Howlett
Love, (William Eubank, 2011), 1.45am, BBC2
There are shades of 2001 and The Martian about this strange, mini-budget sci-fi drama concerning a lone astronaut in space. Gunner Wright is Captain Lee Miller, stranded for seven years aboard a space station orbiting the Earth and mulling over the memoir of a US civil war soldier’s account of the appearance of a strange vessel during a battle. Paul Howlett
