Good omens

The world is preparing to come to an end according to the Divine Plan recorded in the Nice and Accurate Prophecies of Agnes Nutter Witch (written in 1655). Meanwhile a fussy angel and a fast-living demon have grown fond of living among the earth's mortals for many millennia and are not looking forward to the apocalypse. If Crowley and Aziraphale are going to stop it from happening they must find and kill the Antichrist.
