You know where you are with Kay Mellor. Somewhere in the north, among a group of people brought together by pregnancy or prison, weight or, as in the case of the recent Love, Lies and Records, work. With Girlfriends (ITV), the common denominator is encroaching age. The drama's three protagonists are all knocking on a bit and wondering if life can possibly be so resoundingly over.

Young people will laugh incredulously when you tell them that once upon a time, there was only one television channel in Britain. Now we've lost count, and as even the Queen pointed out in her Christmas broadcast, many of her subjects would now be watching her (no doubt hoping for a walk-on by Meghan Markle) on phones or iPads.

Simon Schama called the Netherlands’ century of success an "embarrassment of riches".

The money went on surface things, on finery and furniture.

One of the much-hyped jewels in the crown of the family-friendly BBC holiday season is this new three-episode adaptation of Louisa May Alcott's much loved novel by Heidi Thomas, the writer of Call the Midwife.

And so, with one last speech on the importance of kindness, Peter Capaldi and Steven Moffat bid farewell to the TARDIS. In their final Doctor Who episode, Twice Upon a Time subverted expectations with a small, sweet adventure which valued character above plot.

Whatever the Waitrose and Morrisons commercials are telling you, as far as TV schedulers are concerned ‘tis the season for murder. Thus a Christmas Maigret has become an instant tradition, with Rowan Atkinson reprising his performance as Georges Simenon’s dolorous detective.

Luca Changretta got his just desserts, Alfie Solomons made a last gasp for the quiet life, and Thomas Shelby revealed his true enemy – Peaky Blinders wrapped up another exciting series in a high-octane and neat finale.

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.
