Cousin Les disturbed privacy (9)
I believe the answer is:
seclusion
'privacy' is the definition.
('seclusion' can be a synonym of 'privacy')
'cousin les disturbed' is the wordplay.
'disturbed' indicates anagramming the letters.
'cousin'+'les'='cousinles'
'cousinles' is an anagram of 'SECLUSION'.
(Other definitions for seclusion that I've seen before include "retirement" , "Privacy; solitude" .)
