- This is how John Looney betrays Michael O'Sullivan in Road to Perdition. The message in question read "Kill O'Sullivan, and all is forgiven."

John Looney's son Connor, on the other hand, is a lot more successful in his part of the betrayal.
- One of the Mouse Guard books had a story where this happened to one of the protagonists, as a ruse by the king of his own land in order to get the guy's wife while at the same time ending a war that the two kings had been engaged in.

- The opening of Return of the Jedi doesn't quite match this to the letter, but the idea is the same: R2D2 and C3P0 are sent to Jabba's palace with a message that they are being traded to Jabba, much to the surprise of C3P0 (but not R2). This is subverted when it turns out to be all part of their plan to rescue Han.
- The Fourth Protocol is about a Soviet plot to detonate a nuclear device on British soil and Make It Look Like an Accident. As such an act violates a secret protocol between the nuclear powers, various people get bumped off because They Know Too Much. A female military scientist is sent to assemble the bomb that the KGB agent played by Pierce Brosnan will detonate. She delivers a message which Brosnan decodes using a one-time pad, then he burns the message claiming that it just confirms her instructions re setting off the bomb. She ends up sleeping with him, and the morning after rolls over in bed and sees the imprint on the notepad: KILL HER. Brosnan immediately shoves a pillow against her chest and fires his gun through it, killing her as she's about to blurt out that the bomb's timer has been set to kill him the moment he activates it.

So Bellerophon was sent to destroy the horrible monster Chimera.
