Marner of fiction (5)
I believe the answer is:
silas
'marner of fiction' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for silas that I've seen before include "Fellow" , "-- Wegg (Dickens, OMF)" , "-- Marner (George Eliot novel)" , "Uncle - (Le Fanu); - Marner (Eliot)" , "Forename of miser" .)
