Malicious devil arranged to import dodgy denim (4-6)
I believe the answer is:
evil-minded
'malicious' is the definition.
(thesaurus)
'devil arranged to import dodgy denim' is the wordplay.
'arranged' indicates anagramming the letters.
'to import' is an insertion indicator.
'dodgy' is an anagram indicator.
'devil' is an anagram of 'evild'.
'denim' is an anagram of 'minde'.
'evild' enclosing 'minde' is 'EVIL-MINDED'.
(Other definitions for evil-minded that I've seen before include "Malicious, wicked" , "Inclined to wicked thoughts" .)
