Ghostly figure (7)
I believe the answer is:
spectre
'ghostly figure' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for spectre that I've seen before include "Sceptre (anag.)" , "after-image?" , "Ghost, phantom, apparition" , "'Phantom, shade (7)'" , "Enemy organisation for James Bond; ghost" .)
