History Main / UndercoverCopReveal

* Occurs in the first episode of ''RookieBlue'', even though he tries to keep his cover even after being arrested. Its finally blown when an old friends greets him heartily as he is about to be processed.

* ''DirtyBusiness'', a rare non-humor book by DaveBarry (although it does have it's moments), is about an illegal casino ship that is also a base for drug dealers, things go wrong, etc. On of the POV characters is a pretty young lady who works as a cocktail waitress, hates her job, and her mother always tells her to quit because it's so dangerous... Makes perfect sense, until the very last part of the book when it's revealed that "cocktail waitress" was just a disguise: she is actually a badass undercover cop, and now everything suddenly sounds a lot smarter.

* In ''TheFastAndTheFurious'' Brian O'Conner reveals to Mia that he is a cop at the end of the movie. The viewer has known this all along but it allows some drama between O'Conner and the girl he has been sleeping with and [[spoiler:eventually persuades her to help him track down the truck thieves]].

* TimothyZahn's not-quite-StarWars SpaceOpera-Mystery-action book ''The Icarus Hunt''. To say more would be to spoil it, though if the reader is both paying attention and actively trying to put the pieces together, it's not ''that'' hard to figure it out ahead of time.
