Evil place (8)
I believe the answer is:
hellhole
'evil place' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for hellhole that I've seen before include "Any very unpleasant place, like Hades" , "Evil or terrifying place" , "Unbearable place" , "Utterly ghastly place" , "Unpleasant place of pain and turmoil; inferno" .)
