Cry of the lovable rogue, being a bit too smart (3,6,2,4)
I believe the answer is:
too clever by half
'a bit too smart' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'cry of the lovable rogue' is the wordplay.
'rogue' indicates an anagram (letters go rogue).
'cry'+'of'+'the'+'lovable'='cryofthelovable'
'cryofthelovable' is an anagram of 'TOO-CLEVER-BY-HALF'.
'being' acts as a link.
Can you help me to learn more?
(Other definitions for too clever by half that I've seen before include "shrewd, but flawed by excessive complexity" , "Play" .)
