* The protagonist of ''Literature/MotherNight'' by Creator/KurtVonnegut works as a radio propagandist for the Nazis in WorldWarTwo, but he is actually a spy for the Allies. He's given a list of things they want him to find out about the Nazis, and after he finds them out he communicates the answer on his radio show by, say, coughing in the middle of a certain sentence if the answer is "yes" and not coughing if the answer is "no", or by using a certain word he wouldn't otherwise use, etc.

* Creator/GeneRoddenberry had served in WorldWarII with a man named Kim Noonien Singh. They lost touch after the war. Roddenberry named two characters after Singh, hoping to attract his attention -- Khan Noonien Singh in the "Space Seed" episode of ''Series/StarTrekTheOriginalSeries'' (and ''Film/{{Star Trek II|The Wrath of Khan}}''); and Noonian Soong, Data's creator in ''Series/StarTrekTheNextGeneration''.

Alice needs to send a message to Bob without Eve overhearing. Unfortunately for Alice, she can't simply meet with Bob in private to discuss it, and sending a private message is either physically impossible or would arouse too many suspicions. The solution? Send a message to everyone, but encode, encrypt, or word it in a way that only Bob will understand the message. Alice might disguise the message in such a way that Eve will think it's a relatively innocent item, such as an advertisement ([[TheOtherWiki Wikipedia]] lists this technique as "[[http://en.wikipedia.org/wiki/Steganography Steganography]]"), worded so that everyone but Bob will misinterpret the meaning, or simply make the message so hard to decode that only Bob could do it.

** One book's Morse code word does not seem to fit with the others. This is actually [[spoiler:the password for a pen smuggled into the orphanage that [[ShoePhone unlocks its GPS capabilities]], which displays locations in a coordinate system that only Minerva uses that the kids also have to figure out.]] Within the box the pen came in is yet ''another'' encrypted message, telling the kids his location ([[spoiler:in those coordinates]]) and to find him if they ever need help.

* ''Manga/ThePromisedNeverland'': Books shipped into the orphanage by William Minerva contain hidden messages to inform the kids of the orphanage of the true nature of the world outside while slipping past Isabella's vigilant security:
** The first messages discovered are contained within the stamps on the inside front covers: The stamps, which depict Minerva's owl emblem, have imperfections on the rings that look like the results of hand-stamping but actually form dots and dashes to create words in Morse code--putting the books in chronological order of publication creates a message urging the kids to escape as [[spoiler:the place is actually a farm run by demons who want to harvest and eat them]].
** A number of his books are also adventure novels, which turn out to be [[spoiler:guides on how to deal with, escape from, and fool monsters and other dangerous creatures that live outside of the orphanage]].

* After his plane was shot down over [[VietnamWar Vietnam]], [[https://en.wikipedia.org/wiki/Jeremiah_Denton US Navy pilot Jeremiah Denton]] was taken prisoner by the Viet Cong, who later put on a televised press conference to show [[BlatantLies how well they were treating enemy captives]]. Denton repeatedly signaled the word 'TORTURE' in Morse Code by blinking his eyes.

** There' a different version in the same book; Winter tells Han about Ackbar's 'kids' acting up, and he inquires about the 'neighbors' -- the New Republic [[HangingSeperately politicians]] and the Empire, respectively. Problem is, this wasn't a code that they'd worked out beforehand -- actually, they never worked it out at all. Han knows Winter means there's been some problems, but not just what they mean. This incident was, bizarrely, a case of RealLifeWritesThePlot. Long before the book was released TimothyZahn told some trusted friends about it and met them at a convention to discuss it further, only to realize that they were surrounded by scifi geeks who would know what he meant if he started talking about Luke and Leia and Han and Chewie, and then he'd be in trouble. So on the fly he called them Brother, Sister, Friend, and Copilot... and it worked.

* '''Film/WagTheDog'': One part of the story regarding the soldier Schumann ([[InventedIndividual a fake American POW for a fake war in Albania]]) is a photo of him in captivity with his sweater ripped in a pattern that "turns out" to be a Morse Code message saying that he's okay and asking for his mother to stay strong.
