I started a "Radio Times #21" thread at
12.02 today but this thread was started later ( unfortunately with people giving answers rather than help).
My post on my 12.02 thread was:-
"I made good progress this week and
thought that there were quite a few clever
clues. The last one I solved was 20a.
With best wishes and as ever special
thoughts and hopes for you Old Gal."
