Well, what else are you going to do when you’re wrapped up in a duvet? I had put this by for a rainy day, which duly arrived. I do love this show, even though the plot was seriously creaky this time, and watching it all over the space of a couple of days meant that the rhythms didn’t really work properly (it becomes more apparent that it’s designed episodically. Real life doesn’t have a climax on the hour every hour…) and the occasional continuity gaffes stick out more clearly – but it was great, and I’m now going to order series five.

What I most like about the program is the emphasis on ‘phronesis’, ie judgement – the people involved are always under pressure to establish their priorities, and the boundaries between good and evil get distinctly blurred. I think it is an essentially tragic vision of the world, ie Greek not Christian, but no less fascinating for that.
