"I think the maggots were a bit over the top, myself," said Aziraphale, but without much rancor.

There were people who called themselves Satanists who made Crowley squirm. It wasn't just the things they did, it was the way they blamed it all on Hell. They'd come up with some stomach-churning idea that no demon could have thought of in a thousand years, some dark and mindless unpleasantness that only a fully-functioning human brain could conceive, then shout "The Devil Made Me Do It" and get the sympathy of the court when the whole point was that the Devil hardly ever made anyone do anything. He didn't have to. That was what some humans found hard to understand. Hell wasn't a major reservoir of evil, any more than Heaven, in Crowley's opinion, was a fountain of goodness; they were just sides in the great cosmic chess game. Where you found the real McCoy, the real grace and the real heart-stopping evil, was right inside the human mind.

"I bet you don't have to be Spanish to be the Spanish Inquisition," said Adam. "I bet it's like Scottish eggs or American hamburgers. It just has to look Spanish. We've just got to make it look Spanish. Then everyone would know it's the Spanish Inquisition."

The men in the room suddenly realized that they didn't want to know her better. She was beautiful, but she was beautiful in the way a forest fire was beautiful: something to be admired from a distance, not up close.

"All the higher life forms scythed away, just like that."

"Terrible."

"Nothing but dust and fundamentalists."

"That was nasty."

"Sorry. Couldn't resist it."

Just when you'd think they were more malignant than ever Hell could be, they could occasionally show more grace than Heaven ever dreamed of. Often the same individual was involved. It was this free-will thing, of course. It was a bugger.

God moves in extremely mysterious, not to say, circuitous ways. God does not play dice with the universe; He plays an ineffable game of His own devising, which might be compared, from the perspective of any of the other players*, to being involved in an obscure and complex version of poker in a pitch-dark room, with blank cards, for infinite stakes, with a Dealer who won't tell you the rules, and who smiles all the time.

Many phenomena — wars, plagues, sudden audits — have been advanced as evidence for the hidden hand of Satan in the affairs of Man, but whenever students of demonology get together the M25 London orbital motorway is generally agreed to be among the top contenders for Exhibit A.

Technically Aziraphale was a Principality, but people made jokes about that these days.

"A demon can get into real trouble, doing the right thing." He nudged the angel. "Funny if we both got it wrong, eh? Funny if I did the good thing and you did the bad one, eh?"

"Not really," said Aziraphale.
