Cast a spell on the way in (8)
I believe the answer is:
entrance
I believe this clue is a triple definition!
'cast a spell on' is the first definition.
(I've seen this before)
'the way' is the second definition.
(entrance is a kind of way)
'in' is the third definition.
(thesaurus)
(Other definitions for entrance that I've seen before include "Enchant" , "Maybe drive" , "Capture" , "appearance" , "arrival" .)
