Well at least they haven’t changed the identity of the killer this time around, but the BBC’s new version of Agatha Christie’s 1939 novel has been modified in other ways. Screenwriter Siân Ejiwunmi-Le Berre and director Meenu Gaur have opted to move the story into the mid-1950s, introducing themes of racism, class prejudice and capitalist exploitation. And you thought it was just a tidy little whodunnit.

In its first series in 2021, Vigil delivered a claustrophobic though frequently absurd tale of murder and Russian spies aboard a British nuclear submarine. This time around it’s the RAF under the spotlight, though its name has mysteriously been changed to the British Air Force.

Folklore tends to depict Dublin as a convivial and picturesque city, with a bar on every corner full of revellers on wild stag weekends, but that’s not what we find in Kin. This is a chilly, menacing Dublin, full of modern but charmless architecture and gripped by organised crime.

It was as long ago as January last year that the prolific Williams brothers, Jack and Harry, delivered their absorbing Australian Outback thriller The Tourist. Hitherto, product seemed to have been pouring out of them almost hourly, whether it was Liar, The Missing and Baptiste or The Widow, Rellik and Angela Black.

The question they’re all asking is, can Shetland survive the loss of Douglas Henshall as DI Jimmy Perez? After all, it was Henshall’s shrewd and quietly anguished performance which gave the show much of its allure. And now there’s no Mark Bonnar either, who could always be relied on to add a soupçon of angst.

Dramatisations of real-life crime have become all the rage on TV, as screenwriter Neil McKay and producer Jeff Pope are well aware. Their history of morbid collaborations includes See No Evil: The Moors Murders, the saga of serial killers Fred and Rosemary West in Appropriate Adult, and, in Four Lives, the story of serial killer Stephen Port.

The problem facing any chef series is that its daily dramas are essentially rooted in the same small, sweaty space. It’s like one of the reductions prepared there, all the flavours compressed into an intense spoonful of sauce.

Adapted by Megan Gallagher from one of Mo Hayder’s Jack Caffery novels (the seventh one, apparently), Wolf might be described as Welsh Gothic, spiced up with a splash of gratuitous sadism. Episode two, for instance, is titled merely “Torture”, which might apply to some of the acting as much as the dramatic content.

Writer Peter Bowker apparently had plans to make six series of World on Fire, but the arrival of Covid after 2019’s first series threw a spanner in the works. Anyway, here’s the second one at last, and it’s a little strange to find that this encyclopedic saga of the Second World War has only advanced as far as the autumn of 1940.

This is possibly not ideal viewing for a spell of sunny weather in June, but Jack Thorne’s drama about a family trying to cope with a terminally ill child is as compelling as it’s painful. Sharon Horgan and Michael Sheen star as parents Andrew and Nicci, and Best Interests probes their private agony in piercingly intimate detail, but the focus also pulls out to encompass prickly issues of ethics, morality and the labyrinthine innards of the NHS.
