She in torment shows spirit (7)
I believe the answer is:
banshee
'spirit' is the definition.
(spirit in Irish mythology)
'she in torment' is the wordplay.
'in' indicates putting letters inside.
'torment' becomes 'bane' (I can't explain this - if you can you should give a lot more credence to this answer).
'she' going within 'bane' is 'BANSHEE'.
'shows' is the link.
Can you help me to learn more?
(Other definitions for banshee that I've seen before include "Wailing woman of Irish legend" , "no one wishes to hear" , "She predicts death in Ireland" , "'Wailing woman, warns of impending death (7)'" , "Ominous wailing spirit" .)
