Miracle man in jail: he criminal! (6)
I believe the answer is:
elijah
'miracle man' is the definition.
'Elijah' can be an answer for 'man'. I'm not certain of the 'miracle' bit.
'jail he criminal' is the wordplay.
'criminal' is an anagram indicator.
'jail'+'he'='jailhe'
'jailhe' anagrammed gives 'ELIJAH'.
'in' is the link.
Can you help me to learn more?
(Other definitions for elijah that I've seen before include "OT, Islamic prophet" , "O.T. prophet who disappeared in fiery chariot" , "Hebrew prophet who disappeared in fiery chariot" , "Hebrew prophet in the time of Jezebel" , "Mendelssohn oratorio" .)
