Causes a scene that would raise the dead, perhaps (6)
I believe the answer is:
seance
'would raise the dead perhaps' is the definition.
I can't judge whether this definition defines the answer.
'causes a scene' is the wordplay.
'causes' indicates anagramming the letters (I've seen 'causing' mean this).
'a'+'scene'='ascene'
'ascene' is an anagram of 'SEANCE'.
'that' is the link.
Can you help me to learn more?
(Other definitions for seance that I've seen before include "Some may arrive late to this meeting" , "Session for spiritualists" , "Dead-contacting session" , "Medium experience?" , "Meeting to attempt to contact the dead" .)
