Towards the setting sun (8)
I believe the answer is:
westward
'towards the setting sun' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for westward that I've seen before include "Direction for young man to go?" , ". . . . . . . . Ho (film) (8)" , "In the direction of the setting sun" , "Away from the east" , "Towards the setting sun" .)
