Disinter a dead body (6)
I believe the answer is:
exhume
'disinter a dead body' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for exhume that I've seen before include "opposite of 5 [ENTOMB]" , "Reveal" , "Dig up, unearth" , "Dig up (a corpse)" , "Disinter a dead body" .)
