Primate has company with devilment? (6,8)
I believe the answer is:
monkey business
'devilment?' is the definition.
(I know that monkey business is a type of devilment)
'primate has company' is the wordplay.
'primate' becomes 'monkey' (monkey is a kind of primate).
'has' is a charade indicator (letters next to each other).
'company' becomes 'business' (I've seen this before).
'monkey'+'business'='MONKEY BUSINESS'
'with' acts as a link.
(Other definitions for monkey business that I've seen before include "Marx Brothers film" , "larking about" , "shady deal" , "may be amusingly projected" , "Mischievous behaviour" .)
