Novel closer for poet (7)

I believe the answer is:

newbolt

I'm a little stuck... Click here to teach me more about this clue!

'poet' is the definition.
(I've seen this before)

'novel closer' is the wordplay.
'novel' becomes 'new' (synonyms).
'closer' becomes 'bolt' (I am not sure about this - if you are sure you should believe this answer much more).
'new'+'bolt'='NEWBOLT'

'for' acts as a link.

Can you help me to learn more?

(Other definitions for newbolt that I've seen before include "Sir Henry ---, patriotic balladeer" , "Sir Henry --, English poet" , "Sir Henry ---, Drake's Drum poet" .)
