Clerk in the 1850 Charles Dickens novel David Copperfield (5,4)
I believe the answer is:
uriah heep
(Other definitions for uriah heep that I've seen before include "Obsequious clerk" , "group of players" , "Iconic hypocrite from Dickens' 'David Copperfield'" , "Dickens character" , "'umble character from David Copperfield" .)
