Only Connect returns on Monday at 8.30 pm on BBC2.
BBC4 starts a new quiz show called Hive Minds on Tuesday at 8.30 pm. Seems to be a word search based but tougher than the sort in puzzle magazines. It may be worth trying by anyone who likes tough quiz shows.
There are 3 clips from the first episode on this link to watch if you want to see what it's like, but they do reveal the answers.
