H Division has a new home in Whitechapel that basks in the white heat of the technological revolution. The police station not only has a telephone but a “microreader” that allows the user to check thousands of miniaturised card indexes. Alas, a wry smile is all the viewer is likely to get from this opening episode of the fourth season. Nothing happens until the last ten minutes.

There is a grand ongoing project in Wales at the moment, the goal of which is to hunt for the deep ancestral DNA of the Welsh people. CymruDNAWales has already made some startling findings, in particular about a dozen all-powerful chieftains from 1500 years ago whose DNA is found in a large number of Welsh males. But enough about Welsh men and women. What about Welsh dogs?

So much has happened since the first of June when Versailles flounced on to our screens with its flowing locks and flashing cocks. The British people have voted to widen the Channel, the Conservatives have a new leader, Labour doesn’t have one and Christopher Biggins has been expelled from the Big Brother house. As Louis XIV might have said: plus ça change…

Incredible but true, Iraqi dictator Saddam Hussein really did hire a largely-British film crew to come to his country and make a movie called Clash of Loyalties, about how Iraq freed itself from British influence in the 1920s and blossomed into an independent state. It never made it as far as a cinema release, but the footage was recently rediscovered in a garage in Surrey by its producer, Latief Jorephani (pictured below).

The comedy of widowhood is the brave territory of Mum. Lesley Manville plays Cathy, whom we meet on the day she is burying her husband Dave – although not literally doing it herself, as has to be explained to the nice but dim new girlfriend of her stay-at-home son Jason (Sam Swainsbury). As the mourners gather at her Chingford semi, each fresh arrival proves more grotesque than the last, and poor Cathy’s face becomes a little more pinched as her heroic reserves of tolerance run almost dry.

Time was when the words “a new sitcom from Ben Elton” wouldn't make anyone's heart quicken with anticipation. I think it's fair to say that after the glorious Blackadder (1983-89), he struggled to write anything so brilliantly, giddily funny, but with Upstart Crow he has made a storming return to form.

Allegedly one of the worst plays Shakespeare wrote (which he may have done in cahoots with Thomas Nashe), the first part of Henry VI emerged victorious from this TV adaptation. Whereas one might think twice about chopping and rejigging Hamlet or King Lear, director and co-adapter Dominic Cooke had applied some muscular compressing and reshaping which meant that the piece gathered pace steadily, and was thundering ahead at full steam by the time it hit the final credits.

Sometimes compared to Boardwalk Empire or The Wire, and raved over by the likes of Brad Pitt, Snoop Dogg and even Jose Mourinho, Peaky Blinders opened its third series by becoming positively Godfather-esque. Writer Steven Knight whisked us away from the satanic mills of Birmingham to Tommy Shelby's sprawling Warwickshire mansion, where the Peakies supremo was trying to celebrate his unexpected wedding to Grace.

At last, after three series, Line of Duty delivered a denouement that felt like a satisfying jackhammer to the solar plexus. In the first series the bent copper under investigation escaped justice by jumping in front of a lorry. In the second there were more loose ends than are generally produced by a rope factory. It turns out that patience is a virtue and we should all have had faith.

Every few months we get a new Project Fear campaign by "experts" announcing that a small glass of Bristol Cream twice a week now qualifies as "binge drinking", and guarantees certain death. However, none of the interviewees in Louis Theroux's latest documentary had paid any attention to these warnings. They were patients at the specialist liver centre at King's College Hospital in south London, and each of them was fighting a different kind of battle with alcohol.
