I call parson about troublemaker (11)

I believe the answer is:

rapscallion

'troublemaker' is the definition.
(rapscallion can mean a mischievous person)

'i call parson about' is the wordplay.
'about' indicates an anagram.
'i'+'call'+'parson'='icallparson'
'icallparson' is an anagram of 'RAPSCALLION'.

(Other definitions for rapscallion that I've seen before include "Scoundrel" , "Terror" , "Plain carols (anag) - rogue" , "mischief maker" , "Monkey" .)

I've seen this clue in The Times.
