That woman from Esher (3)
I believe the answer is:
she
'that woman' is the definition.
(she refers to a woman)
'from esher' is the wordplay.
'from' indicates the answer is hidden within the clue.
'SHE' is hidden in the letters of 'esher'.
(Other definitions for she that I've seen before include "Rider's novel" , "1887 Rider Haggard novel" , "Book" , "lady" , "That woman" .)
