Looked deeper, perhaps (6)
I believe the answer is:
peered
'looked' is the definition.
(peering is a kind of looking)
'deeper perhaps' is the wordplay.
'perhaps' is an anagram indicator.
'deeper' with letters rearranged gives 'PEERED'.
(Other definitions for peered that I've seen before include "Looked searchingly" , "Having been made a Lord < examined" , "Looked closely" , "Look searchingly" , "Looked through narrowed eyes" .)
