Rogue caught accomplice dividing spoils (9)
I believe the answer is:
scallywag
'rogue' is the definition.
(synonyms)
'caught accomplice dividing spoils' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'accomplice' becomes 'ally' (I've seen this before).
'dividing' means one lot of letters goes inside another.
'spoils' becomes 'swag' (I've seen this before).
'c'+'ally'='cally'
'cally' inserted into 'swag' is 'SCALLYWAG'.
(Other definitions for scallywag that I've seen before include "Scoundrel" , "A slangy rascal" , "Good-for-nothing - undersized animal" , "Rogue" , "Delinquent" .)
