"You are, I trust, familiar with the Book of Revelation?" said Madame Tracy with Aziraphale's voice.

"Aye," said Shadwell, who wasn't. His biblical expertise began and ended with Exodus, chapter twenty-two, verse eighteen, which concerned Witches, the suffering to live of, and why you shouldn't. He had once glanced at verse nineteen, which was about putting to death people who lay down with beasts, but he had felt that this was rather outside his jurisdiction.

"Then you have heard of the Antichrist?"

"Aye," said Shadwell, who had seen a film once which explained it all. Something about sheets of glass falling off lorries and slicing people's heads off, as he recalled. No proper witches to speak of. He'd gone to sleep halfway through.

"The Antichrist is alive on earth at this moment, Sergeant. He is bringing about Armageddon, the Day of Judgement, even if he himself does not know it. Heaven and Hell are both preparing for war, and it's all going to be very messy."

Shadwell merely grunted.

"I am not actually permitted to act directly in this matter, Sergeant. But I am sure that you can see that the imminent destruction of the world is not something any reasonable man would permit. Am I correct?"

"Aye. S'pose," said Shadwell, sipping condensed milk from a rusting can Madame Tracy had discovered under the sink.

"Then there is only one thing to be done. And you are the only man I can rely on. The Antichrist must be killed, Sergeant Shadwell. And you must do it.”
