Looked for noble journalist (6)
I believe the answer is:
Here is my best explanation:
'looked' is the definition.
(peering is a kind of looking)
'noble journalist' is the subsidiary indication.
'noble' becomes 'peer' (peer is a kind of noble).
'journalist' becomes 'ed' (short for editor).
'for' is the link.
(Other definitions for peered that I've seen before include "Looked searchingly", "Look searchingly", "Looked through narrowed eyes", "Having been made a Lord < examined" and "Looked closely".)
