Point to the hollow heart of a woman! (4)
I believe the answer is:
nell
'a woman' is the definition.
'point to the hollow heart of' is the wordplay.
'point' becomes 'ne' (NE is an example).
'to' is a charade indicator (letters next to each other).
'heart of' means to look at the middle letters.
The middle of 'hollow' is 'll'.
'ne'+'ll'='NELL'
(Other definitions for nell that I've seen before include "- - Gwynne" , "Dickensian heroine" , "-- Gwyn, 17th-century actress" , "Little --; -- Gwyn" , "little Miss Trent?" .)
