2d. Rich man's sort of nightclubs? (5) - DIVES (Sort of nightclubs) Why 'Rich man'?
7d. Sister in London's business area, one trouble-maker giving voice (9) - ENUNCIATE (Voice)
It looks like 'Sister' = NUN + 'Business area' = EC or ECI + One = I or A, but why is TE or ATE, 'Trouble-maker'?
25a. Anguish of some about match (5) - AGONY (Anguish)
I think it's 'Some' = ANY around GO, but how does Go = 'Match'?
