Manage to melt (3)
I believe the answer is:
run
I believe this clue is a double definition.
'manage' is the first definition.
(I've seen this before)
'melt' is the second definition.
('run' can be a synonym of 'melt')
'to' is the link.
(Other definitions for run that I've seen before include "escape" , "Flow quickly" , "Dart" , "Uninterrupted sequence" , "publish" .)
