Siren, houri (9)
I believe the answer is:
temptress
I believe this clue is a double definition.
'siren' is the first definition.
(I know that siren can be written as temptress)
'houri' is the second definition.
(thesaurus)
(Other definitions for temptress that I've seen before include "Delilah" , "Siren, say" , "Enticing female" , "seductive type" , "Femme fatale" .)
