Could handsome, successful, designer-stubbly Ioan Gruffudd really be a rapist? Yes, according to schoolteacher Laura Nielson (Joanne Froggatt). No, according to Gruffudd’s character Andrew Earlham, a distinguished surgeon and widower apparently horrified to be accused of such a thing.

When the ITV comedy drama Cold Feet returned last year after a 13-year break, it seemed something of a risk. Looking back, after the near-universal acclaim and excellent viewing figures, it’s difficult to think it could have been anything but a sure-fire hit.

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.

It was a coup by ITV to get Homeland writer Patrick Harbinson to pen this paranoid-conspiracy series, and rather droll to get Helen McCrory (wife of Homeland’s Damian Lewis) to play the lead.

Emma Banville is almost too good to be true: a human rights lawyer who houses Syrian refugees, wins the most hopeless cases of wrongful conviction, won’t be bullied by anyone – coppers, prison wardens, the system. OK she smokes, presumably for the stress, and pints of lager don’t sit quite right in her hand. And she’s trying to adopt a child with, somewhat implausibly, John Bishop. But she’s played by Helen McCrory, who can do no wrong, and her heart is in the very epicentre of the right place.

There’s something nasty in Loch Ness – a corpse tied to a curling stone – but, this being tellyland, the real monsters lurk on its shores. The Loch aspires to be a Scottish Broadchurch – Braidkirk? – but, alas, is nothing of the sort.

The latest test of the nation’s perseverance and patience – a snap election called just before the negotiations for Brexit are due to start – seemed like an extraordinary act of hubris at the start. The initial billing of “Strong and stable” vs “Coalition of chaos”, was a statement that implied the Tories’ lead was so big that only by ganging together could the other parties beat it.

Four years ago the BBC dramatised the story of the Lucans. Rory Kinnear donned the forthright moustache and Catherine McCormack played his spouse Veronica as a brittle victim of mental cruelty. The script speculated about the murder of the nanny Sandra Rivett using all the known sources. A year later Laura Thompson’s book A Different Class of Murder was published and last year the vanished earl’s death certificate was issued. That might have been thought to be that. But since 1974 Lucan’s widow – whose official name is Veronica, Dowager Countess of Lucan - stayed mainly silent.

Turning the real-life murder of an 11-year-old boy into a four-part TV drama carries obvious risks (might it be exploitative, sick or in bad taste, for instance?), but judging by this opening episode of Little Boy Blue (ITV), screenwriter Jeff Pope has skilfully walked the line.

“Take your pick. Who shall we talk to first?” DI Alec Hardy (David Tennant) and DS Miller (Olivia Colman) had their three prime suspects waiting for them in custody.
