Night-time coverage of De Niro we'd edited (9)
I believe the answer is:
eiderdown
'night-time coverage' is the definition.
'de niro we'd edited' is the wordplay.
'edited' indicates an anagram.
'de'+'niro'+'wed'='denirowed'
'denirowed' with letters rearranged gives 'EIDERDOWN'.
'of' is the link.
(Other definitions for eiderdown that I've seen before include "what may be on tonight" , "What might keep one warm" , "thermal insulation" , "Warm bedcover" , "what keeps retired people warm" .)
