Deprived person of sanctuary with books (4-3)
I believe the answer is:
have-not
'deprived person' is the definition.
(I've seen this before)
'sanctuary with books' is the wordplay.
'sanctuary' becomes 'haven' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'books' becomes 'ot' (Old Testament).
'haven'+'ot'='HAVE-NOT'
'of' acts as a link.
(Other definitions for have-not that I've seen before include "Person of little material wealth" , "Deprived person" , "Someone with meagre possessions" , "Someone who lacks possessions" , "Poor person" .)
