Inspector Muhsin al-Khafaji of the Iraqi police may be set to become one of those classically dog-eared, depressed and down-at-heel detectives who have proliferated in crime fiction. He could join a lineage that includes Martin Cruz Smith’s battered Russian sleuth Arkady Renko, or Bernie Gunther, anti-hero of Philip Kerr’s Berlin Noir trilogy. Or he may create his own category of one.

The race continues to create the most ridiculous cooking programme on TV. Channel 4’s new brainchild, Crazy Delicious, finds the culinary nutty professor Heston Blumenthal teaming up with fellow-judges Carla Hall and Niklas Ekstedt to become the “Gods of Food”.

An idyllic Scottish classroom full of happy children making sponge paintings of flowers with two enthusiastic young teachers – clearly, doom is in the air. Here comes that sense of dread again a little later at a ceilidh in a village hall, with everyone trying a little too hard to look happy. And it’s soon confirmed in a flash-forward to a pathologist wiping down an autopsy table.

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.

And that’s a wrap: last night concluded 10 years of The Great British Bake Off. This show is the nation’s TV equivalent of comfort food. In the past, it has stuck to a well-worn recipe — the result was fun to fight over but easy to love.

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.

What’s the most ridiculous programme that Channel 4 has ever made? Sex Box? The Execution of Gary Glitter? Extreme Celebrity Detox? Whatever, The British Tribe Next Door is up there vying for supremacy.

What’s extraordinary about Bake Off is not just the staggering complexity of the cooking challenges, but the amount of technical shenanigans that go into turning it into a finished programme (actually, spoiler-averse Channel 4 had teasingly left the ending off my preview version of this week’s show, but you catch my drift).

The themes of food and cookery have already been boiled until the bottom of the saucepan melted, but TV commissioning editors can’t stop searching for new twists in the formula. So how about this one – get a couple of prestigious superchefs, and challenge them to make a perfect copy of that famous mass-produced snack, the KitKat.

This was the first of a two-part investigation into... well, I don't know what. The voiceover of High Society: Cannabis Café said it was an experiment “to test the alleged benefits of weed” and the people featured all had “a personal motivation for getting stoned” as they visited an Amsterdam coffee shop, where dope is sold legally.
