First, the important stuff -
Best wishes, jack aubrey - I hope the treatment goes very well for you.
Now, the other stuff -
Could someone please give a little more detail to justify why this puzzle is a 'masterpiece'? (that word can certainly be applied to the puzzle's theme, but the puzzle itself?) I found the whole thing random in the extreme - from the clues to the solving 'route' to the endgame.
For me, a grid full of non-words and a miserly two columns of 'meaning' is about as far from a 'masterpiece' as you can get.
As it was a 'celebratory' puzzle I had hoped to keep my opinion to myself (sorry, but I almost managed it).
I can see brilliance in the way the puzzle has been designed to provide the bare minimum of forward momentum - but if that's what makes a 'masterpiece', perhaps you could you point out another example.
