In a revelatory interview for the Royal Court’s playwright’s podcast series, David Hare admits to a thin skin. In his adversarial worldview, to take issue with him is – his word – to denounce him. He’s quite a denouncer himself, of course.

Marcella’s writer Hans Rosenfeldt was the creator of Scandi classic TV drama The Bridge, the one that made detectives with emotional disorders the flavour du jour, but you do have to wonder what kind of police force would continue to employ DS Marcella Backland (Anna Friel). On a good day she’s merely rude, argumentative, whiny and confrontational.

Happily, there’s hope for Spiral junkies – as series six ends, we bring you news that series seven has just gone into production. This is just as well, because these last dozen episodes have been an object lesson in how to make TV drama for the mind and body, nimbly evading cop show genre-pitfalls to bring us carefully-shaded characters operating within a Venn diagram of overlapping grey areas. Big kudos, yet again, to showrunner Anne Landois.

We’ve seen some “interesting” series filling BBC Four’s celebrated Saturday evening slot recently, which if nothing else have prompted plenty of below-the-line discussion. Happily, we can now turn our backs on all that and hail the return of the ace Paris-based French cop show Spiral.

A new box-set to relish, six French cinema classics by a cult director, along with a wealth of fascinating extras on a seventh DVD.

This week we were all meant to be gripped by a bunch of ancient geezers nicking diamonds in Hatton Gardens. The postponement of ITV’s nightly four-part drama – the second of four (four!!) different versions of the infamous burglary – is a bit of a mystery. Now you see it on the cover of the Radio Times. Now it’s in mothballs. The beneficiary of this hasty swerve was Bancroft.

Forget Christopher Eccleston and the Lake District. Two years on, Ed Whitmore’s ready-mix thriller Safe House returns with Stephen Moyer in Merseyside. He plays Tom Brook – not the venerable film critic (Talking Movies is still showing on BBC World), but an ex-cop convinced his successors are making a dreadful mistake.

So who killed Cinnamon? Six weeks ago we saw the strangled sex-worker – packed in a pink suitcase – pushed into Bondi Bay. The finale of Top of the Lake: China Girl withheld enlightenment. Puss, the chief suspect, denied responsibility. Why would the baby-farmer destroy such a valuable (pregnant) asset?

Val McDermid has written close on 30 award-winning thrillers and suspense novels, in four series, since the late 1980s, all of them featuring a lead female protagonist. She herself worked as a journalist and a crime reporter, and the atmosphere is grittily realistic.

Readers have been committed fans since 1992, when the sometime crime reporter Michael Connelly turned novelist.
