Invisible Ink was back in 1995, before I started solving the listener, however I have solved a few of Sabre's puzzles, who often uses ciphers and this is no exception.
The grid filling started off well, but there needs to be a lot of cold solving before the decoding can continue. Often I thought "a word can't fit in there", but sure enough there was. 31 down is a tricky clue, one that I had to work backwards to get.
One of my favourite setters, and yet I feel a slight disappointment with this puzzle, despite its wonderful construction. Perhaps being held up by one of the crucial clued entries took the edge off it. But thanks, as always, Sabre.
When I realised that at one point I had been encoding rather than decoding, I saw that my original start had been right. It was a bit of a slog, though, and I found WordWizard (bought because I had difficulty installing my old Chambers 2003 on 64-bit Windows 7) very useful, as it allows regular expression searches.
What a dreadfully dull puzzle. I expected more from Sabre. There's not even the usual delight to be had from the clues, which in this puzzle are simple (as they needed to be). I do expect the published solution to include the invisible clues, so we know the clues are invisible, not just never written.
I think you're a bit of an optimist Scorpius:-)
I agree there have been (much) better offerings from Sabre in the past, but I enjoyed it all the same. Somewhat of a change from misprints and word searches is no bad thing for me.
Unexpectedly finished it this afternoon. Reading the preamble I couldn't believe there was enough information to actually fill in all the grid! So it is back to 4114 - where I still haven't got the shaded squares.
Surely this would have been more satisfying if the answers to the normal clues had had to be entered in invisible ink ? Then at least the final grid wouldn't look such a dog's dinner ....
Yeah, I considered that too, Trux. Back again after Merlin and a nights sleep, and have managed to solve this, but 32d I am still not happy with. The only available word which fits the (decoded letter) pattern does not fit the clue (which apparantly should be easy). I only hope it is right, for I am going to post it anyway. I liked the idea, unlike some, but I agree it was somewhat tedious.
Yes, I had to get 32d that way too, Rogue-Elf, but once I'd got it I could see that it did fit the clue, though I thought the clue stretched the bounds of what was fair.
I think this is an incredibly ingenious crossword and I cannot imagine the complexities of setting it so that there is only one solution. However I am stuck in the south west corner in the final stages, not helped by failing to solve 31dn & 32dn. Either I've made an error further back along the maze or one or more of the remaining words is not in Word Wizard.
