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.

One thing we know for sure about Erin Carter is that she’s played by Swedish-Kurdish actor Evin Ahmad, and it’s clear right from the start that she’s a woman with a complicated past which she’s trying to run away from. But you’ll have to get to episode four before the mysteries start to unwind themselves.

Netflix scooped up the rights to an armful of Harlan Coben’s standalone novels for a colossal sum, and now Amazon Prime has nipped in and signed up Coben’s series of Mickey Bolitar books, which fall under the “young adult” heading. Shelter is the first one off the blocks.

Despite its cursory nods to new technology, there’s something deliciously old-fashioned about Only Murders in the Building. Now into its third series, it tells the stories of a trio of affluent Manhattanites who make true-life podcasts about the mysterious deaths that occur in their palatial Upper West Side apartment building.

Presented to you by Channel 4’s industrious Walter, Enemy of the People is a punchy Finnish drama which makes some smart and timely observations about life in the age of digital money and poisonous social media.

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 five-part policier is the finale of the current Walter Presents French season, and takes us to the town of Montclair on France’s eastern border. The opening self-contained episode, occupying a chunky two-hour slot, took for its theme the legend of the Pied Piper. In this, you may recall, the children of Hamelin were lured away by the titular itinerant musician and drowned.

Probably because it’s a secret fear shared by many a flyer, aircraft hijacking has become its own screen mini-genre. We’ve already had not only Hijack but also Hijacked, not to mention the Wesley Snipes vehicle Passenger 57, Jodie Foster in Flightplan and Joseph Gordon-Levitt in 7500. In Air Force One, the President himself (played by Harrison Ford) was hijacked. And then there’s Liam Neeson in Non-Stop.

When we consider the storied history of Portuguese television, we naturally think of… er… well, perhaps we'll get back to you on that. But in the meantime there’s Turn of the Tide (or Rabo de Peixe to give it its original title), Augusto Fraga’s surprising and captivating story of a tiny community in the Azores which suddenly finds itself awash with cocaine.
