What if, for once, the predictions are right, and the Apocalypse really is due to arrive next Saturday, just after tea? It's a predicament that Aziraphale, a somewhat fussy angel, and Crowley, a fast-living demon, now find themselves in. They've been living amongst Earth's mortals since The Beginning and, truth be told, have grown rather fond of the lifestyle and, in all honesty, are not actually looking forward to the coming Apocalypse. Now people have been predicting the end of the world almost from its very beginning, so it's only natural to be sceptical when a new date is set for Judgement Day.
You could spend the time left drowning your sorrows, giving away all your possessions in preparation for the rapture, or laughing it off as (hopefully) just another hoax. Or you could just try to do something about it. And then there's the small matter that someone appears to have misplaced the Antichrist.
