Granny let herself breathe out.
Darkness took some of the terror out of the flight. It also meant that if Esk lost interest the broomstick ought to be able to fly under its own rather rusty magic.
“.” Granny said, and cleared her bone-dry throat for a second try. “Esk?”
“This is fun, isn't it? I wonder how I make it happen?”
“Yes, fun,” said Granny weakly. “But can I fly the stick, please? I don't want us to go over the Edge. Please?”
“Is it true that there's a giant waterfall all around the edge of the world, and you can look down and see stars?” said Esk.
“Yes. Can we slow down now?”
“I'd like to see it.”
“No! I mean, no, not now.”
The broomstick slowed. The rainbow bubble around it vanished with an audible pop. Without a jolt, without so much as a shudder, Granny found herself flying at a respectable speed again.
Granny had built a solid reputation on always knowing the answer to everything. Getting her to admit ignorance, even to herself, was an astonishing achievement. But the worm of curiosity was chewing at the apple of her mind.
“How,” she said at last, “did you do that?”
There was a thoughtful silence behind her. Then Esk said: “I don't know. I just needed it, and it was in my head. Like when you remember something you've forgotten.”
“Yes, but how?”
“I - I don't know. I just had a picture of how I wanted things to be, and, and I, sort of - went into the picture.”
Granny stared into the night. She had never heard of magic like that, but it sounded awfully powerful and probably lethal. Went into the picture! Of course, all magic changed the world in some way, wizards thought there was no other use for it - they didn't truck with the idea of leaving the world as it was and changing the people -but this sounded more literal. It needed thinking about. On the ground.
For the first time in her life Granny wondered whether there might be something important in all these books people were setting such store by these days, although she was opposed to books on strict moral grounds, since she had heard that many of them were written by dead people and therefore it stood to reason reading them would be as bad as necromancy. Among the many things in the infinitely varied universe with which Granny did not hold was talking to dead people, who by all accounts had enough troubles of their own.
But not, she was inclined to feel, as many as her. She looked down bemusedly at the dark ground and wondered vaguely why the stars were below her.
For a cardiac moment she wondered if they had indeed flown over the edge, and then she realised that the thousands of little pinpoints below her were too yellow, and flickered. Besides, whoever heard of stars arranged in such a neat pattern?
“It's very pretty,” said Esk. “Is it a city?”
Granny scanned the ground wildly. If it was a city, then it was too big. But now she had time to think about it, it certainly smelled like a lot of people.
The air around them reeked of incense and grain and spices and beer, but mainly of the sort of smell that was caused by a high water table, thousands of people, and a robust approach to drainage.
She mentally shook herself. The day was hard on their heels. She looked for an area where the torches were dim and widely spaced, reasoning that this would mean a poor district and poor people did not object to witches, and gently pointed the broom handle downwards.
She managed to get within five feet of the ground before dawn arrived for the second time.
The gates were indeed big and black and looked as if they were made out of solid darkness.
Granny and Esk stood among the crowds that thronged the square outside the University and stared up at them. Finally Esk said: “I can't see how people get in.”
“Magic, I expect,” said Granny sourly. “That's wizards for you. Anyone else would have bought a doorknocker.”
She waved her broomstick in the direction of the tall doors.
“You've got to say some hocuspocus word to get in, I shouldn't wonder,” she added.
They had been in Ankh-Morpork for three days and Granny was beginning to enjoy herself, much to her surprise. She had found them lodgings in The Shades, an ancient part of the city whose inhabitants were largely nocturnal and never enquired about one another's business because curiosity not only killed the cat but threw it in the river with weights tied to its feet. The lodgings were on the top floor next to the well-guarded premises of a respectable dealer in stolen property because, as Granny had heard, good fences make good neighbors.
