Harry, sorry for the delay in replying. My OH and I were fighting the crowds in M & S.
Isn't it amazing that when one sees the answers, you can't believe that you couldn't work them out! I'm absolutely sure you're right. I probably won't send it in this week as I feel guilty when I haven't completed the puzzle myself but I still get lots of satisfaction from seeing it completed.
My T shirt has a crossword on the front broken into pieces and the logo "I cracked the Wee Stinker" above it, with clues on the back.
I wish you luck if you send in your copy; and a Very Happy Christmas to you and yours.
