Is it always the same bit of Cornish clifftop they gallop along in Poldark? Anyway here it was again, raising the curtain on the third series. As the camera flew in over a gaggle of squawking seagulls spiralling above the foaming surf crashing on the rocks, we could discern a lone horseperson charging across the skyline.

The latest test of the nation’s perseverance and patience – a snap election called just before the negotiations for Brexit are due to start – seemed like an extraordinary act of hubris at the start. The initial billing of “Strong and stable” vs “Coalition of chaos”, was a statement that implied the Tories’ lead was so big that only by ganging together could the other parties beat it.

This is Jimmy McGovern, so it’s no surprise to find ourselves up north and feeling grim. The prolific screenwriter’s latest drama series is located in what is described only as “a northern city” (though apparently it’s 60 miles from Sheffield, which would take you to McGovern’s home town of Liverpool as the crow flies).

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.
