Secreted around part of Greece (5)
I believe the answer is:
crete
'part of greece' is the definition.
(I know that Crete is part of Greece)
'secreted around' is the wordplay.
'around' indicates a hidden word.
'CRETE' is hidden in the letters of 'secreted'.
(Other definitions for crete that I've seen before include "Large island south of Greece, once home to the Minoans" , "Greek island, capital Heraklion" , "Herakleion its big port" , "Knossos island" , "Large Greek island" .)
