Hide in Hades, possibly (5)
I believe the answer is:
shade
'hide' is the definition.
(thesaurus)
'hades possibly' is the wordplay.
'possibly' is an anagram indicator.
'hades' with letters rearranged gives 'SHADE'.
'in' is the link.
(Other definitions for shade that I've seen before include "Slight colour difference" , "Partial or comparative darkness" , "Colour; protection from sun" , "Hue" , "Nuance" .)
