Manage to find a ladder (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)
'a ladder' is the second definition.
('run' can be a synonym of 'ladder')
'to find' is the link.
(Other definitions for run that I've seen before include "faster pace needed" , "Unbroken series" , "Manage; career" , "Flow; smuggle (goods)" , "follow a course" .)
