The thread to which Hamish/Soup and chrise have directed you is all about last week’s Prize (with an update from Soup), and won’t help you with this week’s. In case you were wondering!
4 three letter word for in good shape, inside a four letter word for fail to catch. Fish is plural.
7 double def, the second being “2”
14 three letter rock outside four letters get hard. Here 2 is being used as an indicator.
Revisiting this in the warm light of day, I find myself appreciating lots of it even more than when I was solving it.
23 deserves a mention as a COD contender in my view. Lovely surface, full of good things.
