Ifor’s second offering this weekend is at least as good, and in my opinion, even better than his IQ. One of those where you are in the dark about the wider picture but seem to be making incremental progress - and then it all goes to custard. Except in the next couple of steps major light dawns and everything comes together, all difficulties get resolved and the overall shape is clear. And a lovely tribute to the thematic subject into the bargain. Thanks again, Ifor.
