Rapt, fascinated (10)
I believe the answer is:
spellbound
I believe this clue is a double definition.
'rapt' is the first definition.
(I've seen this before)
'fascinated' is the second definition.
(I know that fascinated can be written as spellbound)
(Other definitions for spellbound that I've seen before include "Transfixed, mesmerised" , "Entranced" , "Held rapt" , "enthralled" , "appear hypnotised" .)
