Naughty setter’s going to enjoy appearing in plot (3-7)

I believe the answer is:

ill-behaved

'naughty' is the definition.
(thesaurus)

'setter's going to enjoy appearing in plot' is the wordplay.
'setter's going to' becomes 'ill' (I'll as in 'I will').
'enjoy' becomes 'have' (to enjoy can mean have or have use of).
'appearing in' is an insertion indicator.
'plot' becomes 'bed' (a plot of land).
'have' going within 'bed' is 'behaved'.
'ill'+'behaved'='ILL-BEHAVED'

I've seen this clue in The Times.
