The first series of Liar, one of many thrillers from the fertile keyboards of Jack and Harry Williams, was on ITV back in 2017, so you may have forgotten the somewhat labyrinthine details. In a nutshell, smarmy surgeon and serial rapist Andrew Earlham (Ioan Gruffudd) had been unmasked by the dogged (and sometimes illegal) methods of one of his 19 victims, schoolteacher Laura Nielson (Joanne Froggatt).

“Everybody lies," says property developer Tony to his PA and secret lover Natalie. “Even your mum probably.” And of course he’s not wrong.

It's the smallest lies that can bring you down. When he is asked by a detective how he got on with his family, who have just been murdered in a mass shooting at their Essex farm, Jeremy Bamber (Freddie Fox) says: “Really well. We were friends.” A quizzical look briefly scutters across the face of his cousin Ann Eaton (Gemma Whelan) who overhears.

It was on 16 July 1969 that Apollo 11 lifted off from Florida en route for the Moon, and exactly 50 years later, as we nervously anticipate the dawn of commercial flights into space, the event resonates louder than ever. Here, Professor Brian Cox called it “the greatest achievement in the history of civilisation.” According to veteran broadcaster Sir Trevor McDonald, it was “the most magnificent thing that ever happened.”

Should the Ritz catch up with modernity? This question is posed and immediately answered with another question: Does it need to? Not really, say the staff, clients and celebrity guests that populate this bubbly, formulaic and unashamed celebration of what is, rightly, a gorgeous and historic venue. Sticking tight to tradition and celebrating it – with the help of some very famous talking heads – is what is on offer in ITV's latest show.

Ecological awareness has become de rigueur for any self-respecting celebrity, and if the chances of saving the planet were in direct proportion to the number of renowned personages criss-crossing it on well-intentioned missions, we could all stop worrying. Still, one would much prefer to have Dame Judi Dench doing it than…. others we might mention.

It has become routine to accuse Brexiteers of wanting to bring back the British Empire (though obviously it's OK to run an empire from Brussels), but the charge might more accurately be levelled at ITV.

All is not well in Boston, Lincolnshire. Unemployment, immigration concerns, Brexit frustration, and the highest murder rate in the country. How do you solve the problems of contemporary Britain? Send in an American. And not just that. Bill Hixon (Rob Lowe) is the best: educated to Doctorate level, with the accolade of being America’s top Metropolitan police chief three years running.

The first film in this extraordinary series, Seven Up!, was made for Granada Television’s World in Action in 1964. It picked 14 seven-year-old British children from different social backgrounds, aiming to revisit them every seven years to see how their lives were progressing. Paul Almond directed the first programme, but ever since this has been Michael Apted’s baby.

Have we passed peak Hatton Garden? It’s now four years since a gang of old lags pulled off the biggest heist of them all. They penetrated a basement next door to a safe-deposit company, drilled through the wall, and made off with many millions quids’ worth in diamonds, cash and the like. All but one of them ended up in prison, where they will probably see out their days, being all of them well past pensionable age.
