The novel “Good Omens” by Terry Pratchett and Neil Gaiman was published for the first time in 1990.

Aziraphale is an angel while Crowley is a demon, although they’re part of the opposite factions among them a sincere friendship developed and both of them enjoy their life on Earth, where they have lived for millennia. For this reason the Apocalypse is really a nuisance for them and, despite the fact that it was carefully planned since the Creation, the two them are looking for a loophole to avoid it.

The Antichrist is about to reach the age when he will start manifesting his powers and the only hope for Aziraphale and Crowley is that he grows in a way that never leads him to perform the acts needed to start the end of the world. The plan could work despite the signs of the impending Apocalypse if the child the two are trying to influence was indeed the Antichrist.
