Raises my problem with The Messenger (8)
I believe the answer is:
emissary
'the messenger' is the definition.
(thesaurus)
'raises my problem' is the wordplay.
'problem' is an anagram indicator.
'raises'+'my'='raisesmy'
'raisesmy' is an anagram of 'EMISSARY'.
'with' is the link.
(Other definitions for emissary that I've seen before include "Representative on special mission" , "Representative sent on a mission" , "Diplomatic agent" , "Agent possibly" , "Spy" .)
