She takes me back to mother (4)
I believe the answer is:
emma
'she' is the definition.
(I've seen this before)
'me back to mother' is the wordplay.
'back' is a reversal indicator.
'to mother' becomes 'ma' (ma can mean mother).
'me' reversed gives 'em'.
'em'+'ma'='EMMA'
'takes' is the link.
(Other definitions for emma that I've seen before include "Madame Bovary, perhaps" , "J Austen novel" , "Name of Nelson's Lady Hamilton" , "Jane Austen work - Ms Bunton, former Baby Spice" , "book" .)
