Pre-amble: "All clues and solutions are normal. However, before entry in the grid the down solutions must be treated in a way indicated by elements of the across entries."
I think that I must be being a bit dim here - I have many of the down answers, but am unable to understand how the down entries should be adjusted before entry into the grid. I know that the letters have to be re-arranged somehow, but cannot see any pattern to this. Can anyone help please?
To be honest, I didn't notice anything. I just noticed the pattern after solving a lot of across and down answers and seeing that all the crossers were in alphabetical order. I then used this fact to solve even more clues, working out what letters had also to be present in the answers.
