Hire again free (7)
I believe the answer is:
release
I believe this clue is a double definition.
'hire again' is the first definition.
('lease' can be a synonym for 'hire' so perhaps 'release' is OK for 'hire again')
'free' is the second definition.
(to release someone is to free them)
(Other definitions for release that I've seen before include "Liberate" , "Free from confinement" , "record" , "New film" , "Issue" .)
