I won't answer any more quiz questions, quiztime, even though I sometimes find them intriguing. I decided that some time ago when I spent ages on one question and didn't even get an acknowledgement. But it's a cold day....

I am lucky enough to have a log fire (and I do dry all the logs, no detectable smoke from my chimney today anyway).
I still haven't worked out the answer!
