Finds record sleeves Charlie missed once (9)
I believe the answer is:
discovers
'finds' is the definition.
('discover' can be a synonym of 'find')
'record sleeves charlie missed once' is the wordplay.
I cannot quite see how this works, but
'record' could be 'disc' (eg a CD, compact disc) and 'disc' is located in the answer.
The remaining letters 'overs' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Another definition for discovers that I've seen is " Unearths".)
