Point to a woman in white (5)
I believe the answer is:
ashen
'white' is the definition.
(I've seen this before)
'point to a woman' is the wordplay.
'point' becomes 's' (S is an example).
'to' is a charade indicator (letters next to each other) (I've seen this in other clues).
'woman' becomes 'hen' ().
's' after 'a' is 'as'.
'as'+'hen'='ASHEN'
'in' is the link.
(Other definitions for ashen that I've seen before include "Grey in colour" , "(Of face) pale (with shock)" , "of Tree" , "Pale of face, quite grey" , "White-faced" .)
