Anyone turning on BBC Four last night expecting to watch the first episode of Room at the Top will, at least in part, have got what they were expecting: lashings of sex. Only one problem. It wasn't in Room at the Top. Owing to a late-blooming rights dispute, the BBC decided on the day of broadcast not to go ahead with their new adaptation of John Braine's 1957 novel. On the principle that if you would have liked that, then you'll like this, they had a rummage in the archives and produced a rabbit: their version of Fanny Hill, first broadcast in 2008.
