It's hard to disagree with Matthew Wright, in his brisk analysis of the shortcomings of British crime drama (see below). He notes how flashes of inspiration are smothered by skimpy budgets and the timidity of commissioning editors. The disastrous anti-climax of London Spy was a classic example. A British Sopranos seems further away than ever.

It stands to reason that the contents of a prequel can never be entirely surprising. Some details have to be constants, some plot twists left unturned. As soon as it became clear that the second series of Noah Hawley’s Fargo predated the events of the first by some 25 years, we knew that state trooper Lou Solverson (Patrick Wilson) would be left standing at the end of it. But of all the things to have as a constant, Wilson’s sympathetic portrayal of the steadfast cop was as secure a tether as they come.

Was it just my bewilderment, or were there even more criss-crossing narratives than usual in this third series of The Bridge? As in, unusually expanded levels of human traffic, in various forms of distress, flowing under said structure.

ITV’s Manchester crime series Prey has, like a Premiership football club bought by a billionaire, returned for a new season with the same name but different faces. But these aren’t the shiny young faces of virtue that populate the footballing aristocracy. Prey focuses on compromised officers of the law: righteous protagonists gone to the bad, who lend the plot intriguing shades of grey that match its moral tone with the weather and scenery.

Some things never change. Once more, we join DCI John Luther – though only for a two-part special – as he glues himself to the trail of a serial killer. And once again Luther is played by Idris Elba, a man who can freeze time or make villains throw down their weapons merely by gazing into the camera with an expression of quizzical world-weariness.

Young Bulgarian writer-directors Kristina Grozeva and Petar Valchanov have made a tight, bleak, suspenseful drama in The Lesson (Urok), driven by a commanding, unforgiving performance from actress Margita Gosheva who leads the film. Clearly made on a tight budget (though that doesn’t intrude on production values), their first feature tells an often remorseless story of what happens when the money runs out, which replays themes familiar from the Balkans while also attaining an almost existential dimension.

The city of Boston has been creeping up the charts as a hotbed of cinematic criminality in the last decade. First came Martin Scorsese's Oscar-scooping epic The Departed, then Ben Affleck chipped in with The Town, both movies driven by their portrayal of tightly-knit groups of characters immovably rooted in their native Bostonian soil.

The Saga saga has come round for a third turn of the wheel. Much water has flowed under The Bridge since series two. Without wishing to provoke a visit from the spoiler Stasi, it is safe to reveal that Martin is no longer in the picture. He is currently enjoying Her Danish Majesty’s hospitality, and over the water in Malmö Saga is partnerless. Indeed in the Copenhagen police force, her reputation is no longer just as an oddball with no sense of humour, communication skills or empathy. She’s the one who ratted on her closest colleague.

Fritz Haarmann was – although the term wasn’t in use at the time – the first murderer to be recognised in Germany as a serial killer. He was executed in 1925 after being found guilty of 24 killings. Filmed in late 1973, Tenderness of the Wolves dramatises aspects of the case. It is directed by Rainer Werner Fassbinder’s frequent collaborator Ulli Lomell – they had most recently worked together on Effi Briest.

Crime drama is a bit like the wheel. There’s only so much scope for reinvention. People try to come up with novelties all the time, then you turn on the telly and realise everyone else has had the same idea. Rumpled cops in macs, ex-cops haunted by the past, cops with overbearing bosses descended from Jane Tennison – they’re all out there, all the time. Even the casting department is running on empty. It’s been precisely five days since Unforgotten unveiled a chirpy detective played by Nicola Walker.
