Like the melody from the film "The Ghosts" (8)
I believe the answer is:
haunting
'like' is the definition.
Both the answer and definition are adjectives. Maybe you can see an association between them that I can't see?
'the melody from the film the ghosts' is the wordplay.
I cannot quite see how this works, but
'from' could be 'in' (I've seen this in other clues) and 'in' is located in the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for haunting that I've seen before include "difficult to forget" , "Lingering in the mind, like ghost" , "Persistently troubling" , "pursuit of ghosts" , "Poignant, evocative" .)
