Examined closely, as swordfish might be? (7)
I believe the answer is:
grilled
I believe this clue is a double definition.
'examined closely' is the first definition.
(grill can mean to question)
'as swordfish might be?' is the second definition.
(a swordfish might be grilled)
(Other definitions for grilled that I've seen before include "Cross-questioned - cooked" , "Cooked by radiant heat" , "Cooked; questioned" , "Questioned intensely" , "Cooked under a flame" .)
