I interrupted the devious drama and left with an officer (7)
I believe the answer is:
admiral
'officer' is the definition.
(admiral is a kind of officer)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for admiral that I've seen before include "(White or red) butterfly" , "Navy chief" , "Red butterfly at sea?" , "Senior officer; mad liar (anag.)" , "Naval high-up" .)
