Body snatcher (5)
I believe the answer is:
ghoul
'body snatcher' is the definition.
(I know that body snatcher can be written as ghoul)
This is all the clue.
(Other definitions for ghoul that I've seen before include "Evil spirit or phantom" , "Morbid soul" , "Spirit that robs graves and devours corpses" , "shade" , "Corpse-loving phantom" .)
