A day at the seaside has given some welcome time off from this trial, but wheels must have been turning while I was away. I have worked out what the first five words from the misprints mean, and have discovered nine words. Do they have any relevance, or is it enough merely to have noted that they exist. The rest of that message is clear enough, but carrying it out remains anything but. I assume that the letters and numbers in the printed grid are meant to be useful, but I can’t see a way of cracking the way in. Are there hints which might light the way, or at least the first few steps?
