Hi, brendan,
Many thanks for posting the link. There was a shorter version in The Observer on Sunday.
I started doing the Azed puzzles regularly in the 1990s, and for a few years I entered the monthly clue-setting competitions. I’m currently working my way through the Chambers Book of Azed Crosswords, published back in 2005, and many of the puzzles are from the period when I was trying my hand at clue-writing.
