Silent Witness
9pm, BBC One
The UK police join forces, awkwardly, with the US embassy in this episode of the enduring forensic pathology drama, as a diplomat heading home finds himself targeted and then murdered by a biker. The Lyell team discovers the victim posed on a bench, sitting with his hand in his jacket. Meanwhile, romance blossoms between Nikki and FBI head Matt, but then he goes missing. Might Nikki be the next target? The only touch of reality is an oblique reference to the current, deeply unpopular US administration. David Stubbs
How Mad Was King George?
7.50pm, PBS America
It has become a cliche that George III was a deranged simpleton, so much so that it inflamed revolution among Americans, who would obviously never tolerate being governed by such a creature. This film begs to differ, highlighting his patronage of the arts and his defence of the monarchy. Andrew Mueller
Inside the Ambulance
8pm, W
A new series returns to the tireless West Midlands Ambulance Service. Louise, whose degenerative spinal disease means she is on first-name terms with paramedics, needs to be taken to hospital after going into an agonising spasm. To add to the drama, even the journey to New Cross hospital is not without incident. Ben Arnold
Surgeons: At the Edge of Life
9pm, BBC Two
We go behind the theatre doors at the Queen Elizabeth hospital in Birmingham for the final part of this fly-on- the-wall doc. Tonight, surgeons Richard Laing and Thamara Perera are part of a team attempting a new kind of liver transplant, while there is also a new approach to prostate cancer. John Robinson
Next of Kin
9pm, ITV
This stilted drama about a British family caught up in international terrorism has the same flaw as BBC One’s McMafia. Every episode has a thrilling development, but not until the very end, after 50 deathly minutes. Tonight, Archie Panjabi does lots more pained, inert moping before it finally kicks off. Jack Seale
The Undateables
9pm, Channel 4
Formulaic it may be, but this show rarely fails to serve up moments of uplift. This week’s cast include a railway enthusiast with Asperger’s, a musician with learning difficulties and a woman re-entering the dating game after a stroke. How will these eminently dateable individuals fare? Phil Harrison
Film choice
The Way Way Back (Nat Faxon, Jim Rash, 2013) 6.55pm, Film4
Another slice of dysfunctional family life from the writers of The Descendants. It is the story of 14-year-old Duncan (Liam James) who, on holiday with his mother (Toni Collette) and her schmucky boyfriend (Steve Carell), seeks refuge at the Water Wizz aquapark. Perceptive, clever and funny. Paul Howlett
