Stuck as usual!
I've got the grid filled in, have a name running down from 5,
But (there's always a but!) with the extra letters I've got the first 4 words of the question and the last three, but I'm left with a very random selection of letters in the middle (I've double checked my extra letters and feel they are correct)
Also I don't understand " resolved by the exchange of 12 letters to give the submission grid"
Any help (I don't want another sleepless night!) would be gratefully appreciated!
Thanks in advance
The 'exchange of 12 letters' refers to the name running down from 5.
The name you have at the moment was also the name/character you've to replace him with. Any help?
