DIVORCE. It’s about as much fun as DIY tooth extraction. How then to tackle the subject in a primetime drama and not send the nation to bed depressed?

Ignore it as much as possible was the answer provided by The Split (BBC1, Tuesday, 9pm). The opening episode featured warring couples in solicitors offices, but they were largely there as props around which the main characters could operate. A bit like the patients in Casualty, clients did the suffering while the doctors, or in this case the divorce lawyers, dashed around in nice clothes, bickering, flirting, lunching and trying to steal clients from each other before going back to their fabulous London homes.

Nicola Walker played central character Hannah, who used to be a senior partner in her family’s all-female firm of divorce lawyers. From Spooks to Last Tango in Halifax, Walker usually plays boring, sensible sorts. Not any more. Hannah has a new blonde hairdo to mark her jumping ship from the family firm. Oo-er.

Meanwhile, Hannah’s husband might or might not be becoming too friendly with her sister; mother is upset that her estranged husband (Anthony Head) has turned up after decades away; and the baby of the family is preparing to wed. One would think, given the way the rest of the family earn a crust, she would have taken herself to a nunnery, but hope springs and all that.

Written by Abi Morgan (The Hour), The Split is Ally McBeal meets Little Women by way of Doctor Foster: unbelievable but very moreish.

The Cancer Hospital (BBC1, Wednesday, 9pm) followed several women through their treatment for breast cancer at the Beatson in Glasgow, the second biggest centre of its kind in the UK. This was a no-fuss documentary, the first of three, that told its stories straight and was all the more compelling for it. It was the quiet, small moments that spoke volumes, like a patient and nurse holding hands at a consultation, or the face of a father on hearing the best possible news about his daughter.

Britain’s Fat Fight with Hugh Fearnley-Whittingstall (BBC1, Wednesday, 10.45pm) found the celebrity chef who once declared war on food waste spoiling for another battle. With two-thirds of Britons overweight, we are on the way to becoming the fattest country in Europe. If crisp eating was a sport we would lift every trophy in the book. Who is to blame: the industry or us?

A bit of both was the answer, and as Hugh ran his way through one sensible idea after another, all the while taking branded cereal firms to task for not making sugar content clearer, I nodded along vigorously. So vigorously, in fact, I might even have burned off some of the calories from the scone I was eating at the time.

The opening scene of The Woman in White (BBC1, Sunday, 9pm) featured a distressed damsel who looked in sore need of some comfort food, if such a concept had existed in the 19th century. Instead, she had to make do with spilling her strange tale, and her tears, for a solicitor in some dusty Victorian office.

Starring Jessie Buckley as boyish Marion Halcombe, Olivia Vinall as lamb to the slaughter Laura and Charles Dance as their drama queen of an uncle, The Woman in White is as fine a Sunday night treat as hot buttered crumpet. Speaking of which, Dougray Scott turned up at the end of episode one as Sir Percival Glyde. Never did a moustache look so likely to be twirled in villainy. Bring it on, you bounder.

The Real Camilla (ITV, Monday, 9pm) banged on a lot about unprecedented access being given to film the Duchess of Cornwall in her 70th year. I should think so too, given the lashings of positive PR she got out of it.

Yes, the D (for Diana) word was used, and the subject of Camilla’s unpopularity in some quarters was raised, but as pal after pal, from Joanna Lumley to Gyles Brandreth, lined up to pay tribute, the scales were heavily weighted in Camilla’s favour.

To what benefit it was not clear. We learned nothing new about her, and the glimpses afforded into her life with Prince Charles amounted to little other than showing them as a couple of a certain age living the good life. ITV could run The Real Camilla 52 weeks a year and it still would not change minds already made up.

It’s a bit like the story the duchess told of Charles acquiring Dumfries House in Ayrshire. Before it was done up, Camilla visited, detected a ghostly presence and turned tail, vowing never to return. She did, though, once renovations were complete. Finding the ghost gone, she moved in. Other ghosts will not be banished so easily.
