There is something about the quiet late at night when most other people have finished for the day, isn't there? I get much of my best work done between nine and eleven.

Really, though, I'm writing about the chill. It is extremely brisk out there, so I've already asked the house-elves to make sure to have some warm tea when we come back in, and the fire in my office is going strong if anyone needs to stop in and warm up.

The wind's up, too, so we may not stay out terribly long: it'll rather depend on whether we can take notes and discuss without the pages blowing off.
