Points to the girl to follow (5)
I believe the answer is:
ensue
'to follow' is the definition.
(ensue can mean to follow or happen as a result)
'points to the girl' is the wordplay.
'points' becomes 'en' (compass points east and north).
'to the girl' becomes 'sue' (girl's name).
'en'+'sue'='ENSUE'
(Other definitions for ensue that I've seen before include "Transpire" , "Come about, result in" , "Arise" , "Result in a particular way" , "Follow as a consequence" .)
