Two left, unless I've made mistakes elsewhere they are
N Clay with pearly association: review in the scotsman's negative (7) N_C_ _ _ E
K What sleep does for the sleeve of care for Macbeth, producing clue to nasty smell (5,2) K _ _ _ S / _ P
N is nacrite. CRIT in NAE.
I'm sure the A clue is a typo, but still can't work it out!
Only thing I can find for K is KNITS UP but can't see the connection.
Can anyone else help?
BTW is Z ZOMBA (city in Malawi)?
