Traces
9pm, Alibi
The watchable Scottish forensics drama returns for a second season (back on Alibi, after its short transfer to the BBC during the pandemic) and things kick off with a literal bang: the women of the Scottish Institute of Forensic Science and Anatomy get stuck in to finding out who’s behind a Dundee bombing. Meanwhile, Daniel (Martin Compston) prepares for his dad’s murder trial, but is also celebrating some good news (though others think it’s terrible). Just watch out for the clunky, often cringeworthy dialogue. Hollie Richardson
This Is Going to Hurt
9pm, BBC One
Not a single second is wasted in this comedy-drama about the reality of being an NHS doctor. Tonight’s highlights: an excruciating dinner party with a friend and his pregnant fiance (“We’re going to ‘play it safe’ and go private,” she announces); the rediscovery of a “misplaced” Kinder Surprise egg; and a flurry of razor-sharp quips to camera from Ben Whishaw.

The Gilded Age
9pm, Sky Atlantic
“I haven’t been thrilled since 1865.” Christine Baranski is still in fine, sharp-tongued form here. Episode four picks up in the aftermath of the tragedy – will Mr Russell suffer any moral consequences? He is too busy dealing with an indecent proposal (the raunch factor goes up a notch). Meanwhile, Marian is thinking about a future with Mr Raikes without her aunts’ approval. HR
The Devil’s Advocate
9pm, Sky Documentaries
Nice man, Giovanni di Stefano … In case we haven’t had enough of appalling liars and frauds recently, this sprawling three-parter interrogates the bizarre life of the would-be movie mogul and convicted conman who claims to have acted as criminal defence lawyer for the likes of Harold Shipman and Ian Brady (albeit without any formal legal qualifications). Ali Catterall
Cheaters
9.45pm, BBC One
The perfectly paced storytelling of this comedy about two neighbours’ infidelity is so satisfying it’s hard not to wish that all sitcoms adopted its 10-minute-long format. In tonight’s trio of instalments, Fola and Josh continue to pack sex-based laughs into their ever more messily intertwined lives. Alexi Duggins
Lazy Susan
10.45pm, BBC Three
Celeste Dring and Freya Parker’s sketch show features them as Teesside teen boys and the leads in a mid-century Hollywood musical, as well as in more conventional skits set in restaurants and bars. Tonight: the very real danger of laughing one’s ass off. Jack Seale
