Look for wild, deranged missing journalist (6)
I believe the answer is:
'look' is the definition.
(informal term for a look or glance)
'wild deranged missing journalist' is the wordplay.
'wild' indicates an anagram.
'missing' is a deletion indicator.
'journalist' becomes 'ed' (short for editor).
'deranged' with 'ed' taken away is 'derang'.
'derang' with letters rearranged gives 'GANDER'.
'for' is the link.
(Other definitions for gander that I've seen before include "Glimpse" , "waterbird" , "Male 7 across" , "Goose sauce is good for it" , "Butchers - goose" .)
