Obsessed with Aunt Edwina’s shows (7)
I believe the answer is:
haunted
'obsessed' is the definition.
(I know that obsessed can be written as haunted)
'with aunt edwina's shows' is the wordplay.
'shows' says the answer is hidden in the clue.
'HAUNTED' is hidden within 'with aunt edwinas'.
(Other definitions for haunted that I've seen before include "Ghost-ridden" , "Spooky" , "with the ghost still around?" , "Full of ghosts" , "Possessed" .)
