It took me a while to realise that it was easiest to fit the normal solution into the grid and then work back. And a lot of it seems almost arbitrary. I am still trying to work back on and justify seven!
But I would love some help on my last clue, 17D. The word I have is a sports term (if I have 16A across correct and it starts with an I and ends with an S). But the word doesn't fit with either the first or last definition. Any hints, please?
Don't expect an immediate thanks as I am fed up and off to play pétanque.
