The red and black opening titles, in which a creepy house looms large, immediately tells the viewer we are in Hitchcock territory. However, Thirteen Steps Down, knowingly adapted for the small screen in two parts by Adrian Hodges, is based on Ruth Rendell’s 2005 novel of the same name. Like Hitchcock, Rendell knows there is laughter in slaughter.

“It was almost undescribable but I’ll give it a go.” Anyone from the group of athletes we have come to know as Team GB might have given voice to the thought, but the words happened to belong to Ed McKeever, one of the less charismatic of the freshly medalled guests to take his place on Gary Lineker’s sofa. Lineker, offering nightly sessions as some sort of entry-level shrink to the nation, spent the Olympic Games asking people to describe how they feel. It was a thankless gig, but someone had to keep popping the question. “Unbelievable, Gary,” they'd all say.

In the debating chambers and committee rooms of the Conservative Associations of Oxford and Cambridge lurk the Children of Cameron. The current cabinet is to a large extent an Oxbridge Old Boys club and succeeding generations are already being fattened up for the fray. Young, Bright and on the Right - and what an aimless title that was - picked two candidates and sharpened the knives.

American critics haven't been too kind to Aaron Sorkin's new HBO series about a cable TV news programme, for a variety of reasons. At least they had the advantage of understanding the intricate partisan infighting of American politics which forms the show's backdrop, and which will be baffling to many British viewers. On the other hand, nobody is likely to have much trouble recognising the A Few Good Men view of history familiar from previous Sorkin milestones such as The West Wing and, uh, A Few Good Men.

What do you do after nine series celebrating the cooking and eating of food? You make another, charting the effort to lose some of the weight gained. This time out, the bike-riding Si King and David Myers are still eating and travelling, but trying to adjust what they put in their mouths, to make it less calorie-tastic. Some exercise was on the menu too. As was selling copies of the tie-in book.

It’s not usually a good sign when the second series takes two years to materialise. Vexed , a comedy drama with corpses, took its first bow a couple of years ago. It offered Toby Stephens as DI Jack Armstrong, a detective from the old school who’s rather more mouth than trousers. There can’t have been much confidence in it back then: August is the cruellest month for fresh television content when the target audience is generally off on its hols.

Having begun as a piece of fan fiction derived from the Twilight movie series, EL James's Fifty Shades of Grey has blown up into the publishing phenomenon du jour. It's supposedly the UK's fastest-selling book of all time, and has sold nearly 50 million copies worldwide. In the process, with its copious descriptions of BDSM (or bondage, discipline and sado-masochism), it has gathered a vast mostly-female fanbase and fostered the creation of the term "mummy porn".

If he isn't careful, Daniel Barenboim is going to find himself on a plinth in Trafalgar Square. He was feted at the Olympic opening ceremony as a great humanitarian, and his West-Eastern Divan Orchestra is being held up as a model for how music can bridge political and ethnic divides, with particular reference to the Middle East.

Oh to have been a fly on the wall at the Palace. “Your Majesty, we’ve had a request from a Mr Boyle. It concerns the Opening Ceremony of the Olympic Games.” “I’m already opening the blessed thing, aren’t I? What else do they want?” “Ma’am, they just want you to be yourself.”

So, how are we all feeling about David Starkey? The historian’s reputation has taken a battering lately, since he was seen last year taunting overweight schoolchildren on Jamie’s Dream School and more recently causing Twitter to combust after criticising black culture on Newsnight. But if Channel 4 is to be believed, such displays of bullying and bigotry haven’t dented his authority as a historian.
