Good omens: the nice and accurate prophecies of Agnes Nutter, witch

According to the Nice and Accurate Prophecies of Agnes Nutter -the world's only _totally reliable_ guide to the future - the world will end on a Saturday. Next Saturday, in fact. Just after tea. Which means that Armageddon will happen on a Saturday night. There will be seas of fire, rains of fish, the moon turning to blood and the massed armies of Heaven and Hell will sort it outonce and for all. Which is a major problem for Crowley, Hell's most approachable demon and former serpent, and his opposite number and old friend Aziraphale, genuine angel and Soho bookshop owner. They like it down here (or, in Crowley's case, up here). So they've got no alternative but to stop the Four Motorcyclists of the Apocalypse, defeat the marching ranks of the Witchfinder's army and - somehow - stop it all happening. Above all (or, in Aziraphale's case, below all) they need to find and kill the Antichrist, currently the most powerful creature on Earth. This is a shame. Because he's eleven years old, loves his dog even though it's really a Satanic hellhound under all that hair, really cares about the environment and is the sort of boy anyone would be proud to have as a son. He's also totally invulnerable, and a nice kid. And if that isn't enough, they've still got Sunday to deal with.
