You're a braver solver than I, dd. I looked at this and -- to be sure, in part because I thought I should make the most of my time in the South of France -- put it away without much extra thought. Looks like it could be a great puzzle but requires more time than I have.
It's very hot here, and I'm afraid to say that I've not really adapted to that very well. Been out and about, and had a great time, but right now I'm suffering the effects of not putting enough suncream on. Damn near ripped my skin off in various places, and it hurts rather. Ah, well.
