Book front of theatre in Surrey town (6)
I believe the answer is:
esther
'book' is the definition.
(book of the Hebrew Bible)
'front of theatre in surrey town' is the wordplay.
'front of' indicates taking the first letters.
'in' indicates putting letters inside.
'surrey town' becomes 'esher' (I've seen this before).
The first letter of 'theatre' is 't'.
't' going inside 'esher' is 'ESTHER'.
(Other definitions for esther that I've seen before include "There's a girl from the Old Testament" , "Old Testament queen" , "There's the biblical woman" , "__ Rantzen, TV presenter, b. 1940" , "Set her with this girl" .)
