I'll admit to suffering from Iforphobia and maybe that - and my usual word search problem - is stopping me from seeing the obvious. I have a full grid, have done what is suggested by the extra letters and I think I know who will need highlighting. but for the life of me can't see the letter which needs to be changed. A pointer in the right direction would be much appreciated.
I didn't have to go through the whole grid in my wordsearch - I spotted a likely candidate exactly halfway through. A quick visit to Google, using the ordered strings, confirmed things, and the letter to change.
Thanks for that Malone. I suspect I've gone wrong somewhere because that's the first place I looked, both across and down and nothing leapt out at me. It's also possible I've extracted the wrong letters from 31 across and 8 down. I'll leave it now until tomorrow.
