Happy Monday. I don't remember where the idea for this one came from, but definitely one of those "can I turn this into a puzzle" thoughts.
Thanks to
Abide and
Wendy Walker for test solving, and for some key fill/clue tweaks. Thanks also to Wendy for spotting a rather nasty red herring that I didn't even know was a fish.
Thanks as always to Joe Ross for tech support.
I don't think it's especially difficult (maybe week 1.5 on the Gaffney scale), but if you get stuck, fear not, nudges will be forthcoming on Wednesday. Solution on Sunday.
Hope you enjoy!
cheers,
Alan
