If anyone is wondering whether to start this puzzle - please do! I am not the strongest sudoku solver but with the help of a little hint from the setter (that in no way spoiled the break-in as there were several more steps I had to take), I managed to start the puzzle. It's a wow moment and well executed. The rest of the puzzle is of an equally high standard. Thanks for making it.
