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' says the answer is hidden in 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" .)
