Turn in books confiscated by judge (6)
I believe the answer is:
rotate
'turn in' is the definition.
(thesaurus)
'books confiscated by judge' is the wordplay.
'books' becomes 'OT' (abbreviation for Old Testament).
'confiscated by' is an insertion indicator.
'judge' becomes 'rate' (rating is a kind of judging).
'ot' inserted within 'rate' is 'ROTATE'.
(Other definitions for rotate that I've seen before include "Pivot" , "Turn around an axle, swivel" , "Move round centre" , "Whisk round" , "Spin round" .)
