Manage to smuggle (3)
I believe the answer is:
run
I believe this clue is a double definition.
'manage' is the first definition.
(both can mean to organise)
'smuggle' is the second definition.
(I've seen this before)
'to' is the link.
(Other definitions for run that I've seen before include "trip" , "Ladder - manage - sprint - flow" , "work" , "follow a course" , "Flow; smuggle (goods)" .)
