Morag Tinto’s documentary is a profile of composer Alma Deutscher, who hit the headlines at the end of last year when her opera based on the Cinderella story premiered in Vienna. What’s unusual about that, you might ask?

So who killed Cinnamon? Six weeks ago we saw the strangled sex-worker – packed in a pink suitcase – pushed into Bondi Bay. The finale of Top of the Lake: China Girl withheld enlightenment. Puss, the chief suspect, denied responsibility. Why would the baby-farmer destroy such a valuable (pregnant) asset?

Cast your minds back, if you will, to 2011. Remember Jamie Oliver’s Celebrity Fight School?

By the outrage it prompted, you’d be forgiven for thinking that The Great British Bake Off’s move to Channel 4 was a national disaster. If only the public felt so indignant about the sale of the Post Office, or the creeping privatisation of a beleaguered NHS… but hey-ho, cakes it is, then. 

Trust Me made an eponymous plea to the audience. Its implausible premise – that a nurse might steal a doctor’s identity and land a job in A&E – called for your credulity. Around the broadcast of the drama's first episode on BBC One, sundry articles sprang up in the media offering supportive evidence that just such scenarios often come to pass for real.

There’s a new ‘tec in town. Cormoran Strike may look like one of life’s losers – he’s on the edge of bankruptcy, sleeps in the office, and what passes for a personal life is a right mess – but in Tom Burke’s portrayal I suspect he’s going to be winning audiences in a big way. He’s the creation, of course, of JK Rowling, writing as Robert Galbraith – the author’s chosen anonymity lasted barely three months – and her debut in crime writing is now a satisfyingly stylish BBC adaptation.

Journalist Mark Austin is no stranger to conflict, having reported from war-torn landscapes including Rwanda, Iraq and even the ITN newsdesk. However, when the battle lines were drawn closer to home and involved an enemy he couldn’t see, the veteran journalist found himself in unfamiliar territory and without any kind of roadmap. 

It’s a burning question of western civilisation: what persuades young people brought up among us to walk out on their lives and join the cult of murderous fanatics who call themselves Islamic State? If any dramatist could attempt a coherent answer it’s Peter Kosminsky, who for more than three decades has been telling minutely researched stories – in documentary, drama and a fusion of both – about the big moments of modern British social and political history.

Whether it’s the £400,000 that separates Mishal Husain from John Humphrys, or the 74 million miles between the metaphorical markers of Venus and Mars, there is a gulf between the genders. Despite legislation to enforce equality, the reality is that, right from the start, boys and girls are treated differently. Boys like trains, right? Girls like dolls… Before you know it, female students are massively under-represented in the sciences, and worrying numbers of young men think it’s OK to shout sexual threats to women on the street in the name of banter.

The first thing to say is that this wasn’t the actual end. BBC Four scheduled I Know Who You Are to run two episodes a night over five Saturdays. The innocent punter might have assumed that after 10 x 70 minutes of the Spanish import, we’d arrive at some sort of terminus. With only a few minutes still to run, who wasn’t thinking, crikey, still quite a tick list of bows to tie up?
