Detective dropped, frustrated (6)

I believe the answer is:

dished

'frustrated' is the definition.
(thesaurus)

'detective dropped' is the wordplay.
'detective' becomes 'di' (Detective Inspector abbreviation).
'dropped' becomes 'shed' (shedding is a kind of dropping).
'di'+'shed'='DISHED'

(Other definitions for dished that I've seen before include "Made slightly concave" , "Spoilt" .)

I've seen this clue in The Independent.
