A traveller in obscure places (3)
I believe the answer is:
rep
'a traveller' is the definition.
(travel company worker)
'in obscure places' is the wordplay.
'in' indicates a hidden word.
'REP' can be found hidden inside 'obscure places'.
(Other definitions for rep that I've seen before include "Corded fabric" , "Sort of theatre" , "Theatre; fabric; salesman" , "Material for curtains" , "agent" .)
