Maybe Smollett’s books reflected prejudice (6)
I believe the answer is:
tobias
'maybe smollett's' is the definition.
(poet Tobias Smollett is an example)
'books reflected prejudice' is the wordplay.
'books' becomes 'OT' (Old Testament).
'reflected' says the letters should be written in reverse.
'prejudice' becomes 'bias' (biasing is a kind of prejudicing).
'ot' back-to-front is 'to'.
'to'+'bias'='TOBIAS'
(Other definitions for tobias that I've seen before include "Biblical man" , "-- Smollett, novelist" , "Boy" .)
