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

This skilfully-woven drama about an NHS doctor being battered by professional and personal pressures is undoubtedly timely, and benefits greatly from being written by Grace Ofori-Attah, a former NHS doctor herself. Her inside knowledge lends weight and verisimilitude to scenes depicting admission procedures or the way the treacherous politics of NHS hierarchies work, and perhaps most significantly, how internal investigations are conducted.

Endeavour first landed way back in 2012, and suddenly here we are, bidding it a final farewell after the end of its ninth series. Not everybody learned to love Shaun Evans as the pre-John Thaw Inspector Morse, but some of us may even have come to like the new boy better.

A disclaimer in the opening credits confessed that some scenes in this three-part history of disgraced Labour MP John Stonehouse had been “imagined for dramatic purposes”, but there was no need. The man’s life story fell comfortably into the “you couldn’t make it up” zone, and there wasn’t really much that screenwriter John Preston needed to add.

In 10 series stretching over the last 18 years, ITV's Doc Martin unobtrusively became an enduringly popular household name, but it finally reached the end of the road with this Christmas one-off. Unless, of course, there’s a prequel, a sequel, an origin story or a transformed internationalised version from Netflix.

Although plaudits have been rolling in for Lauren Lyle’s smart and sparky portrayal of the titular detective in Karen Pirie (ITV), getting to the end of the third and final episode felt like a long slog.

Despite the jarring effect of having British actors speaking colloquial English while purporting to be Dutch policemen working in Amsterdam, the second series of ITV’s Van der Valk arrived at its third and final episode feeling as if it had reached its comfort zone.

Connoisseurs of the Britbox streaming service may already have caught up with this three-part series, which has evidently been pressed into service on ITV to pad out TV’s annual summer slump. They could have called it Midsomer Murders Goes to the Côte d’Azur, as it details the adventures of Investigating Judge Antoine Verlaque (Roger Allam) and his partner Marine Bonnet, a criminal psychologist played by Nancy Carroll.

Somehow or other, fictional representations of the police have become an off-the-cuff index of changing times and evolving values. Dixon of Dock Green’s cops were stern father figures who knew right from wrong and considered it their duty to give villains a clip round the ear. The Sweeney weren’t quite so sure about right and wrong but gave everybody a good kicking anyway, while risking a bollocking from the boss for their blatant rule-bending.

The terrain Holding occupies is well travelled, but this new ITV four-part drama travels over it really well. The landmarks are familiar: a quiet rural community, a cop with an unhealthy lifestyle and a secret sorrow, a feud between rival lovers of the local lothario, a long-buried trauma that’s suddenly unearthed. We could be in any rural location in the primetime drama of the past half-century.
