In answer to all who replied to my message.
1. I probably could have solved it if I had gone on long enough but I gave up in the end after having put in more pencil marks in than you can imagine and after having had 2 goes ( using logic - not guesses). I find that I cannot work on fiendish puzzles casually. Full focus from beginning to end is essential.
2.Perhaps I get so upset that I have not solved the thursday one that I work harder on fridays!!
3. And no, I did not think #124 easy
