Took another look at grey area lady uncovered (6)
I believe the answer is:
reread
'took another look at' is the definition.
I don't understand the rest of the clue.
(Other definitions for reread that I've seen before include "Study text again" , "Give script second seeing to" , "Perused again" , "look again at manifesto?" , "Peruse or scan again; it's dearer" .)
