Bewitching girl that wails loudly (5)
I believe the answer is:
siren
I believe this is a double definition.
'bewitching girl' is the first definition.
'that wails loudly' is the second definition.
(Other definitions for siren that I've seen before include "Alarm; temptress" , "Temptress; warning signal" , "Loud whistle or dangerous woman" , "Charmer" , "Alluring female" .)
