“Are they all like that?” asks a shaken Major Bucky Egan (Callum Turner), after he’s completed his first bombing mission over Germany as a guest of the US Eighth Air Force’s 389th Bomb Group. They’ve been battered by flak and lacerated by German fighters, and the front half of their B-17 bomber looks like an abattoir. His pilot looks ahead with a thousand-yard stare, and says “don’t tell your guys anything, they’ll figure it out.”

It’s not easy to find a new way to package a drama about that perennially popular topic, the dark side of policing, but Criminal Record at least gets its ducks in a row with some strong writing by Paul Rutman and a strength-in-depth cast.

There isn’t a troupe officially called the Worshipful Company of British Character Actors, but there probably should be, given the sterling service it does for the nation, acting in prestige TV dramas based on real events. Toby Jones and Monica Dolan regularly top the bill in this genre, as they do in ITV’s Mr Bates vs The Post Office.

It was barely a month ago that screenwriters Jack and Harry Williams astounded viewers with Boat Story. Now they’re back with a sequel (or maybe just a continuation) of The Tourist, which debuted a year ago with its mind-bending story of the amnesiac Elliot Stanley (Jamie Dornan), who found himself all at sea in the Australian outback.

TV viewers can hardly complain about a lack of choice these days, though they might baulk at funding an ever-lengthening list of subscriptions.

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.

Having previously brought us adaptations of M R James’s ghost stories, reviving the BBC tradition inaugurated by Lawrence Gordon Clark in the 1970s, Mark Gatiss has now turned to a short story by Arthur Conan Doyle for his annual Christmas chiller. With its cast of upper-crust academics amid the shadowy staircases and wood-panelled studies of Old College, Oxford in the 1880s, it makes a fine addition to the canon.

Not just one, but two Santas in this agreeable seasonal romp. It’s set in small-town Northern Ireland, where single mum Patricia (Laura Donnelly) is struggling to bring up her two young sons, Mikey (Bamber Todd) and Sean (Joshua McLees). Her job at the Stuff for a Pound shop is barely keeping food on the family table, her boss Mr Brady (Lloyd Hutchinson) is a bully and a liar, and her son Mikey is exhibiting anti-social tendencies (by blowing up the school Christmas tree, for instance).

The original title of this French crime drama was Pax Massilia, a reference to the classical roots of its setting in what is now known as Marseille. Dating back to the 6th Century BC, it’s supposedly the oldest city in France. An atmospheric mix of architectural styles, dramatic views, a Mediterranean climate and multiple ethnicities, it makes the perfect stage for this fast-paced and sometimes horrifically violent thriller.

Stranger Things has shown us over four seasons that the alternate dimension known as the Upside Down can be the seat of many things: terror, mystery, camaraderie, compassion. As it turns out, it can spawn great theatre, too, for Stephen Daldry’s much-anticipated stage production of the prequel to the Netflix mega-hit has finally summoned its demonic energy to take the West End by storm.
