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 the answer is hidden within the clue.
'HER' is hidden in the letters of '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" .)
