As some commenters have ruefully noted, TN has been on a lull for the past fortnight. I have a few reviews to write - and will, I hope, in the near future. This time I don't even have the excuse of being distracted by other work: I simply seem to have run out of words. It's a mysterious inability: as Orwell noted once, when a writer says he can't write, he really can't. However, this paragraph is a note of intent, and perhaps returning writerliness.
