Happily, Joe Barton’s tinglingly original thriller (BBC Two) finished as smartly as it began, not by any humdrum tying-up of loose ends but by giving free rein to the story’s ambiguities and impossible choices. If indeed they really were choices.

The first series of The Sinner in 2017 starred Jessica Biel as a disturbed woman who seemingly inexplicably stabbed a man to death on a beach, then could remember nothing about the crime. This second season on BBC Four finds Biel on board as executive producer, but this time the story is of a young boy who seemingly inexplicably poisons a couple, and admits to doing it.

“Talking cures and exploring the darkness of men’s souls – are you sure this is a career for a gentleman?” This is Vienna, 1906. Freud is exerting an influence, to the disapproval of many, including the father of cool-as-a-cucumber Max Liebermann (Matthew Beard).

Although it conforms to a realistic chronology of events, this third season of Peter Morgan’s remarkable voyage around the House of Windsor (on Netflix) has the feel of a sequence of standalone dramas, linked together by its interrelated characters and their shared history.

Channel 4’s The Accident closed with a bang and a whimper. Jack Thorne provided a definitive answer to his series’ central question, but his characters and subplots petered out in the meantime.

A tip of the hat to Julia Ormond for boldly going where many an actress might have chosen not to. In this new six-parter by Marnie Dickens, she plays Julia Day, a mother of three who’s just divorced her husband and is turning 60. Dickens’s objective, we may surmise, was to drive away the fog of invisibility which can descend irrationally upon mature women, however capable they may be, and demonstrate that age can indeed be just a number.

A bit like all those people on the home front in 1940 (but only a little bit), we sit and nervously wait for news. Is World on Fire (BBC One) still listed among the living? Or even now is someone typing up the letter and sticking it in a brown envelope? “Fell bravely in the field … did its country proud etc…” Please may this ambitious Sunday-night drama live to fight another day?

You wouldn’t expect a drama called Dublin Murders (BBC One) to be a laugh a minute, but the cumulative anguish, menace and torment of this eight-parter made it almost unbearable, even if viewers were thrown a tiny scrap of hope in the final frames.

Pose offers something that is really rare in the TV world: it’s a show that manages to be both darkly sombre and completely uplifting. The drama, which is about New York City’s 1980s ball culture, focuses on the lives of trans women and gay men competing for glory in the ballroom while fighting for their lives on the streets.

I wouldn’t want to live in Jack Thorne’s head. Nor Sarah Lancashire’s, for that matter. The Accident is Thorne’s latest four-part drama, and the final instalment in his grim and gripping trilogy of shows for Channel 4.
