Writer Norman (6)
I believe the answer is:
mailer
'writer norman' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for mailer that I've seen before include "person at the post?" , "American author of The Naked and the Dead, d. 2007" , "writer from America" , "One putting armour on" , "novelist" .)
