Satisfied I would come back with the news (4)
I believe the answer is:
item
'news' is the definition.
(I've seen this in another clue)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for item that I've seen before include "Also no more" , "Component" , "Piece of news: unit" , "Single article on a list" , "Object in a list" .)
