Quite agreed setter has books as compensation (9)
I believe the answer is:
atonement
'compensation' is the definition.
(I know that atonement is a type of amends)
'quite agreed setter has books' is the wordplay.
'quite agreed' becomes 'atone' (to be 'at one' is to be agreed. I am not sure about the 'quite' bit.).
'setter' becomes 'me' (the setter of the clue).
'has' is a charade indicator (letters next to each other).
'books' becomes 'NT' (abbreviation for New Testament).
'atone'+'me'+'nt'='ATONEMENT'
'as' is the link.
Can you help me to learn more?
(Other definitions for atonement that I've seen before include "Making good" , "Making amends" , "reparations?" , "satisfaction" , "Expiation of sin, penance" .)
