Runaway (8)
I believe the answer is:
fugitive
'runaway' is the definition.
(I know that runaway can be written as fugitive)
This is the entire clue.
(Other definitions for fugitive that I've seen before include "One fleeing captivity" , "One on the run" , "The . . . . . . . .'s name is Dr Richard Kimble" , "He's on the run, perhaps from justice" , "Runaway from justice" .)
