Dickensian Heep (5)
I believe the answer is:
uriah
(Other definitions for uriah that I've seen before include "Dickensian hypocrite ... Heep" , "Husband of Bathsheba" , "King David had him killed in battle in order to marry his wife, Bathsheba" , "12 [HITTITE] officer" , "'Umble --- Heep (Dickens)" .)
