Listen in without the speaker knowing (9)

I believe the answer is:

eavesdrop

(Other definitions for eavesdrop that I've seen before include "Listen without the speaker's knowledge" , "Listen carefully" , "Hold secret hearing" , "Listen at windows" , "Listen in, earwig" .)

I've seen this clue in The Guardian.
