Hello, Elle!
I find I have to concentrate on my puzzle.
If I have something on my mind I can not do it.
But, it is a long, long, time since I could not finish one.
Maybe your mind was occupied?
Speaking of apples, I was reading about Granny Smith.
Her name was Maria, and she created her apple in Australia.
Still a bit windy here.
Now a wee help.
The word I did not know what it meant was 14a.
"Valetudinary", it's an anagram.
The one that the setter and Chambers agree on is, 5d.
"Gunslinger" for "cowboy", which I did not like!
