I hope you sorted your Inquisitor scaling issue. I tried accessing the puzzle online several months ago but had no joy and gave it up as a bad job. You were cleverer than me. The Guardian puzzles are at least free and easy to access , so nothing to be lost by trying a selection. I didn’t mean to damn those I omitted, such as Brummie, Boatman, Nutmeg, but I couldn’t list them all. Brendan is a particular favourite of mine. There’s almost always a theme I don’t spot until it’s too late to be useful.
Bless your mother-in-law for still having a go! That’s most impressive. Let’s hope they do stave off dementia, or else I have no chance
