Hamlet revealing evil without delay (7)
I believe the answer is:
village
'hamlet' is the definition.
('village' can be a synonym of 'hamlet')
'revealing evil without delay' is the wordplay.
'revealing' indicates an anagram.
'without' means one lot of letters goes inside another ('without' can be similar in meaning to 'outside').
'delay' becomes 'lag' (lag is a kind of delay).
'evil' is an anagram of 'vile'.
'vile' placed around 'lag' is 'VILLAGE'.
(Other definitions for village that I've seen before include "Small residential area" , "Goldsmith poem 'The Deserted .......'" , "little place" , "Small community" , "Rural community" .)
