Spirit shown by woman in trouble (7)
I believe the answer is:
banshee
'spirit' is the definition.
(banshee is a kind of spirit)
'woman in trouble' is the wordplay.
'woman' becomes 'she'.
'in' indicates putting letters inside.
'trouble' becomes 'bane' (as in a menace or trouble to someone's life).
'she' put within 'bane' is 'BANSHEE'.
'shown by' is the link.
(Other definitions for banshee that I've seen before include "Mythical Gaelic wailing woman" , "Ominous wailing spirit" , "Howler" , "'Wailing woman, warns of impending death (7)'" , "She predicts death in Ireland" .)
