Good-looking policeman, retiring (5)
I believe the answer is:
dishy
'good-looking' is the definition.
(I've seen this before)
'policeman retiring' is the wordplay.
'policeman' becomes 'di' (I've seen this in other clues).
'retiring' becomes 'shy' (I've seen this in other clues).
'di'+'shy'='DISHY'
(Other definitions for dishy that I've seen before include "Good-looking (informal)" , "Informally good-looking, like plate?" , "Handsome" , "Gorgeous" , "Attractive" .)
