The BBC’s latest “cool” Agatha Christie adaptation has many hallmarks of the decidedly dark ones that were considered prestige Christmas treats until recently. But although it’s lovely to look at, it’s low on chills and thrills.

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.

“Wagatha Christie” – I salute the bright spark who coined the term – describes, for those who don't follow such fripperies, the social media spat between footballers' wives Rebekah Vardy and Coleen Rooney (married to Jamie and Wayne respectively), which later became the subject of an multimillion-pound court case.

With Magpie Murders currently airing on BBC One, Why Didn’t They Ask Evans? is another gem from the BritBox stable, where it made its debut last year. Its secret weapon is Hugh Laurie, who’s all over it as screenwriter, director and actor.

A starry cast headed by Saoirse Ronan and Sam Rockwell doesn’t quite manage to bring this lavish, light-hearted period pastiche to life, though it looks good – nice cars, lovely costumes, a quasi-Wes Anderson vibe – and there are mild chuckles to be had.

Death on the Nile, Kenneth Branagh's second visit to Agatha Christie's oeuvre, was supposed to be released in November 2020 but Covid, a studio sale and some embarrassing revelations about one of its cast members put paid to that. Was it worth the wait? Not really.

Lucy Bailey's production of Christie's Witness for the Prosecution, first staged at County Hall in 2017, has a few years to make up on The Mousetrap's near 70, but it has already proved its staying power, despite the hiatus of the lockdown months.

Christmas and Agatha Christie are a very good fit – how better to spend time with your loved ones than sitting down to watch some murder and intrigue together?

Ordeal by Innocence belongs to a new and, you hope, short-lived sub-genre. The only other stablemate is All the Money in the World. Both were in the can and good to go when very serious sexual allegations were made against a member of the cast. For the latter, Ridley Scott reshot every scene which featured Kevin Spacey, subbing in Christopher Plummer.

Crooked House is being released as a film in various territories, but has already been shown on television in America and has now surfaced as a drama on Channel 5 bearing the title Agatha Christie’s Crooked House. It duly falls in with a recent televisual tradition for serving up the Queen of Crime as a Christmas treat.
