Hi there
4A - Fish (or grouse) I had with mother's cheese (10)
??S??????? - MASCARPONE (mother's = MAS, fish = CARP, I = ONE)
13D - Famous rock group's huge influence and inner spark (6, 8)
?????? ???????Y - GIANTS CAUSEWAY - not able to pars completely but obviously huge = GIANT and I think influence = sway
I'm also puzzled in other places :
56A - Ordered head of branch to assess one's condition (10)
?S?E?T?S?S - ASBESTOSIS
40D - Must pay individual sum when reporting very high deficit (5, 4)
O???E ?O?E - OZONE HOLE (OZ sounds like 'owes', individual = one, sum = whole)
20D - Twice annually, daughter's constrained to suffer consequences (3, 6)
P?Y YEARLY - PAY DEARLY - twice yearly is PA and YEARLY enclosing D for daughter
Hope this helps!
I am stuck on 32a: 'Stick at protecting peace project' for which I have ?S?P?A?T
Any help gratefully received!
