Asset in a covert op (3)

I believe the answer is:

spy

(Other definitions for spy that I've seen before include "Discover" , "Keep watch secretly, maybe for foreign government" , "Person who secretly collects information as for government" , "One gathers information on enemies" , "Glimpse" .)

I've seen this clue in the LA Times.
