Imagined face, in conclusion (9)
I believe the answer is:
envisaged
'imagined' is the definition.
('envisage' can be a synonym of 'imagine')
'face in conclusion' is the wordplay.
'face' becomes 'visage' (visage is a kind of face).
'in' indicates putting letters inside.
'conclusion' becomes 'end' (something's conclusion is its end).
'visage' put into 'end' is 'ENVISAGED'.
(Other definitions for envisaged that I've seen before include "Contemplated" , "Fancied" , "Imagined" , "anticipated" , "Pictured" .)
