Edward returned hurt and isolated (8)
I believe the answer is:
detached
'isolated' is the definition.
(I know that isolated can be written as detached)
'edward returned hurt' is the wordplay.
'edward' becomes 'ted'.
'returned' says the letters should be written backwards.
'hurt' becomes 'ached' (I've seen this before).
'ted' written backwards gives 'det'.
'det'+'ached'='DETACHED'
'and' is the link.
(Other definitions for detached that I've seen before include "Separate, disconnected" , "isolated" , "being sent on special assignment" , "cut off" , "Unprejudiced" .)
