She-devil out to produce disorder (8)
I believe the answer is:
dishevel
'disorder' is the definition.
(thesaurus)
'she-devil out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'she'+'devil'='shedevil'
'shedevil' is an anagram of 'DISHEVEL'.
'to produce' is the link.
(Other definitions for dishevel that I've seen before include "get into a mess" , "Make untidy" , "Get ruffled" , "Disarrange - rumple" , "Ruffle (e.g. hair)" .)
