Ned returns to hideout (3)
I believe the answer is:
den
'hideout' is the definition.
('den' can be a synonym of 'hideout')
'ned returns' is the wordplay.
'returns' says the letters should be written in reverse.
'ned' back-to-front is 'DEN'.
'to' acts as a link.
(Other definitions for den that I've seen before include "Miserable place" , "Animals' shelter" , "Habitation of wild animals (3)" , "Wild animal's lair" , "Cave" .)
