Fugitive, deserter (7)
I believe the answer is:
runaway
I believe this clue is a double definition.
'fugitive' is the first definition.
(I know that fugitive can be written as runaway)
'deserter' is the second definition.
(thesaurus)
(Other definitions for runaway that I've seen before include "One who flies" , "such a success?" , "refugee?" , "One who has taken flight" , "Fugitive" .)
