Courier (9)
I believe the answer is:
messenger
'courier' is the definition.
(I know that courier can be written as messenger)
This is all the clue.
(Other definitions for messenger that I've seen before include "Person carrying information to another" , "Bringer of news, etc" , "He brings the news - don't shoot him" , "He's just bringing the word - don't shoot him" , "Courier - don't shoot him" .)
