Savalas in box (5)
I believe the answer is:
telly
I believe this is a double definition.
'savalas' is the first definition.
(I've seen this in another clue)
'box' is the second definition.
(both can mean a television set)
'in' is the link.
(Other definitions for telly that I've seen before include "Familiar name for TV" , "cop in seventies" , "'The box' (colloquial)" , "The goggle-box" , "- - Savalas" .)
