Criminal trick has six coming to court (7)
I believe the answer is:
convict
'criminal' is the definition.
(thesaurus)
'trick has six coming to court' is the wordplay.
'trick' becomes 'con' (I've seen this before).
'has' means one lot of letters go next to another.
'six' becomes 'vi' (roman numeral).
'coming to' is a charade indicator (letters next to each other).
'court' becomes 'ct'.
'con'+'vi'+'ct'='CONVICT'
(Other definitions for convict that I've seen before include "Prove guilty" , "Jailbird" , "Find guilty - criminal in prison" , "Declare guilty (of crime)" , "One serving time" .)
