Television dramas about catastrophic events in broken Britain are meant to be cathartic. They knead the collated facts into the shape of drama for millions to absorb and understand. Then we all somehow move on, sadder but slightly wiser. The Murder of Stephen Lawrence. Hillsborough. The Government Inspector. And still they flow onto the screen: only recently there’s been Damilola: Our Loved Boy, The Moorside and Little Boy Blue.

EastEnders habituees will be familiar with the colourful past of Alfie and (especially) Kat Moon, who have both been AWOL from the mothership since early last year. But they’ve used the time wisely, preparing busily for this new spin-off drama in which they’ve shipped out to the seaside village of Redwater, County Waterford, to track down Kat’s long-lost son.

Barbara Windsor’s laugh belongs in the National Sound Archive. It’s a birdlike chuckle that wavers between innocence and dirt. We all know Babs’s laugh. But what about her tears? There have been plenty of those too according to Babs, BBC One’s feature-length drama which sifted through the jigsaw pieces of a tumultuous life spent in the public eye.

Cop a load of that, then. Hana Reznikova is serving time for triple murder. Ted Hastings is on permanent gardening leave. The Huntleys have renewed their wedding vows on a family trip to Disneyworld. Just kidding. This is a Reg 15 alert to advise you that the following paragraphs contain almost nothing but spoilers.

Like many first novels, Evelyn Waugh’s Decline and Fall has a strong whiff of autobiography. It is a revenge comedy in which Waugh – like Kingsley Amis after him in Lucky Jim – transmutes his miserable experiences of teaching in Wales into savage farce.

Now promoted to the exhilarating landscapes of BBC One as a reward for previous good behaviour, Line of Duty set off at a scorching pace into the murky shadowland where crime, punishment, ambition and corruption mingle treacherously.

In the end, SS-GB promised more than it could deliver, but it still left us with some memorable images (not least in the cleverly-crafted opening titles) and several excellent performances. The ending even dangled the faintest hint of a sequel, though presumably not one written by the author of the original book, Len Deighton.

At the end of last year’s third series of Line of Duty, we saw the back of the reprehensible Dot “The Caddy” Cottan, and with the much-abused Keeley Hawes consigned to the show’s morgue of deceased leading characters it felt as though important matters had come to a close. I was dubious about LoD when it began in 2012, but what has gradually become apparent is that its mastermind Jed Mercurio (pictured below) has been playing a long, labyrinthine game.

Can women have it all? (Stop me if you’ve already heard this one). This is the premise of Joe Ahearne’s new three-part drama, set in the offices of a successful firm of architects in Glasgow. But he’s a bloke, what would he know about it?

“What if the Germans had won the war?” has been a recurring theme in fiction, from Noel Coward’s Peace in Our Time to Philip K Dick’s The Man in the High Castle and Robert Harris’s Fatherland. There was even a predictive pre-war “future history” version, in the form of Katherine Burdekin’s 1937 novel, Swastika Night.
