Detective and judge working overseas with Grace O'Malley (6)
I believe the answer is:
pirate
'working overseas with grace o'malley' is the definition.
I can't tell whether this definition defines the answer.
'detective and judge' is the wordplay.
'detective' becomes 'pi' (I've seen this in other clues).
'and' means one lot of letters go next to another.
'judge' becomes 'rate' (rating is a kind of judging).
'pi'+'rate'='PIRATE'
Can you help me to learn more?
(Other definitions for pirate that I've seen before include "Penzance marauder ?" , "Publish without permission" , "Illegal" , "Captain Hook, say" , "Freebooter" .)
