Miss Marple (4)
I believe the answer is:
jane
'miss marple' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for jane that I've seen before include "Tarzan's woman" , "... novel by 19 10" , "Tarzan's girl" , "Book by Charlotte Bronte" , "- - Lapotaire, Fonda" .)
