That woman's in the right (3)
I believe the answer is:
her
'that woman's' is the definition.
('her' refers to a woman)
'in the right' is the wordplay.
'in' indicates a hidden word.
'HER' can be found hidden inside 'the right'.
(Other definitions for her that I've seen before include "That lady's" , "The female's" , "In the Midlands she" , "That lady" , "Belonging to a female" .)
