Reviled in notes about us (6)
I believe the answer is:
'reviled' is the definition.
(similar in meaning)
'notes about us' is the wordplay.
'notes' becomes 'abed' (I can't justify this - if you can you should believe this answer much more).
'about' means one lot of letters goes inside another.
'abed' going around 'us' is 'ABUSED'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for abused that I've seen before include "Offended", "Insulted; violated", "Mistreated", "Swore at", "Treated cruelly; insulted".)
