She has a fatal aura of fascination about her (5)
I believe the answer is:
laura
'her' is the definition.
'she has a fatal aura of' is the wordplay.
'she' becomes 'Lu'.
'has' indicates putting letters inside.
'fatal aura of' becomes 'ra' (I can't justify this - if you can you should believe this answer much more).
'lu' placed around 'a' is 'lau'.
'lau'+'ra'='LAURA'
'fascination about' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for laura that I've seen before include "Petrarch loved her" , "- Ashley, Welsh clothing and furniture designer" , "- Ashley, Welsh clothes, furnishings designer" , "Cells of a group of recluses" , "Girl's name" .)
