That lady from Esher (3)
I believe the answer is:
she
'that lady' is the definition.
('she' refers to a woman)
'from esher' is the wordplay.
'from' indicates the answer is hidden within the clue.
'SHE' can be found hidden inside 'esher'.
(Other definitions for she that I've seen before include "H. Rider Haggard novel" , "The one who must be obeyed" , "- - Loves You (Beatles)" , "That woman" , "1887 Rider Haggard novel" .)
