Heep of "David Copperfield" (5)
I believe the answer is:
uriah
'heep of david copperfield' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for uriah that I've seen before include "Biblical figure" , "Husband of Bathsheba" , "embezzling clerk" , "... Heep, obsequious character in David Copperfield (Dickens)" , "'Umble --- Heep (Dickens)" .)
