Spiritualist's session (6)
I believe the answer is:
seance
'spiritualist's session' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for seance that I've seen before include "Spiritualist meeting, all hold hands" , "Sitting, session" , "Spiritualist's sitting" , "spiritual guidance" , "Psychic gathering" .)
