"I wonder what he wanted?" said Magrat.

After half an hour the boat drifted out through a cave mouth and into a narrow gorge between cliffs. Ice glistened on the walls, and there were drifts of snow on some of the outcrops.

Nanny Ogg looked around guilelessly, and then fumbled somewhere in the depths of her many skirts and produced a small bottle. There was a glugging noise.

"I bet there's a fine echo here," she said, after a while.

"Oh no you don't," said Granny firmly.

"Don't what?"

"Don't sing That Song."

"Pardon, Esme?"

"I ain't going," said Granny, "if you insists on singing That Song."

"What song would that be?" said Nanny innocently.

"You know the song to whom I am referring," said Granny icily. "You always get drunk and let me down and sing it."

"Can't recall any song like that, Esme," said Nanny Ogg meekly.

"The one," said Granny, "about the rodent that can't -that can't ever be persuaded to care about anything."

"Oh," said Nanny, beaming as light dawned, "you mean The Hedgehog Can Never Be Bugg- "

"That's the one!"

"But it's traditional," said Nanny. "Anyway, in foreign parts people won't know what the words mean."

"They will the way you sings them," said Granny. "The way you sings them, creatures what lives on the bottoms of ponds'd know what they mean."

Magrat looked over the side of the boat. Here and there the ripples were edged with white. The current was running a bit faster, and there were lumps of ice in it.

"It's only a folk song, Esme," said Nanny Ogg.

"Hah!" said Granny Weatherwax. "I should just say it is a folk song! I knows all about folk songs. Hah! You think you're listenin' to a nice song about... about cuckoos and fiddlers and nightingales and whatnot, and then it turns out to be about... about something else entirely," she added darkly. "You can't trust folk songs. They always sneak up on you."

Magrat fended them off a rock. An eddy spun them around slowly.

"I know one about two little bluebirds," said Nanny Ogg.

"Um," said Magrat.

"They may start out by being bluebirds, but I bet they ends up some kind of mettyfor," said Granny.

"Er, Granny," said Magrat.

"It was bad enough Magrat telling me about maypoles and what's behind ‘em," said Granny. She added, wistfully, "I used to enjoy looking at a maypole of a spring morning."

"I think the river's getting a bit sort of rough," said Magrat.

"I don't see why people can't just let things be," said Granny.

"I mean really quite rough, really..." said Magrat, pushing them away from a jagged rock.

"She's right, you know," said Nanny Ogg. "It's a bit on the choppy side."

Granny looked over Magrat's shoulder at the river ahead. It had a cut-off look, such as might be associated with, for example, an imminent waterfall. The boat was now surging along. There was a muted roar.

"They never said anything about a waterfall," she said.

"I ‘spect they thought we'd find out for ourselves," said Nanny Ogg, gathering up her possessions and hauling Greebo out of the bottom of the boat by the scruff of his neck. "Very sparin' with information, your average dwarf. Thank goodness witches float. Anyway, they knew we'd got the brooms."

"You've got brooms," said Granny Weatherwax. "How'm I supposed to get mine started in a boat? Can't run up and down, can I? And stop movin' about like that, you'll have us all over - "

"Get your foot out of the way, Esme - "

The boat rocked violently.

Magrat rose to the occasion. She pulled out the wand, just as a wavelet washed over the boat.

"Don't worry," she said, "I'll use the wand. I think I've got the hang of it now - "

"No!" screamed Granny Weatherwax and Nanny Ogg together.

There was a large, damp noise. The boat changed shape. It also changed colour. It became a cheery sort of orange.

"Pumpkins!" screamed Nanny Ogg, as she was gently tipped into the water. "More bloody pumpkins!"

Lilith sat back. The ice around the river hadn't been that good as a mirror, but it had been good enough.

Well. A wishy-washy overgrown girl more suitable to the attentions of a fairy godmother than to being one, and a little old washerwoman-type who got drunk and sang songs. And a wand the stupid girl didn't know how to use.

It was annoying. More than that, it was demeaning. Surely Desiderata and Mrs Gogol could have achieved something better than this. You derived status by the strength of your enemies.

Of course, there was her. After all this time...

Of course. She approved of that. Because there would have to be three of them. Three was an important number for stories. Three wishes, three princes, three billy goats, three guesses... three witches. The maiden, the mother and the... other one. That was one of the oldest stories of all.

Esme Weatherwax had never understood stories. She'd never understood how real reflections were. If she had, she'd probably have been ruling the world by now.

"You're always looking in mirrors!" said a petulant voice. "I hate it when you're always looking in mirrors!"

The Duc sprawled in a chair in one corner, all black silk and well-turned legs. Lilith would not normally allow anyone inside the nest of mirrors but it was, technically, his castle. Besides, he was too vain and stupid to know what was going on. She'd seen to that. At least, she'd thought she had. Lately, he seemed to be picking things up...

"I don't know why you have to do that," he whined. "I thought magic was just a matter of pointing and going whoosh."

Lilith picked up her hat, and glanced at a mirror as she adjusted it.

"This way's safer," she said. "It's self-contained. When you use mirror magic, you don't have to rely on anyone except yourself. That's why no-one's ever conquered the world with magic... yet. They try to take it from... other places. And there's always a price. But with mirrors, you're beholden to no-one but your own soul."

She lowered the veil from the hat brim. She preferred the privacy of a veil, outside the security of the mirrors.

"I hate mirrors," muttered the Duc.

"That's because they tell you the truth, my lad."

"It's cruel magic, then."

Lilith tweaked the veil into a fetching shape.

"Oh, yes. With mirrors, all the power is your own. There's nowhere else it can come from," she said.

"The swamp woman gets it from the swamp," said the Duc.

"Ha! And it'll claim her one day. She doesn't understand what she's doing."

"And you do?"

She felt a pang of pride. He was actually resenting her! She really had done a good job there.

"I understand stories," she said. "That's all I need."

"But you haven't brought me the girl," said the Duc. "You promised me the girl. And then it'll be all over and I can sleep in a real bed and I won't need any more reflecting magic —"

But even a good job can go too far.

"You've had your fill of magic?" said Lilith sweetly. "You'd like me to stop? It would be the easiest thing in the world. I found you in the gutter. Would you like me to send you back?"

His face became a mask of panic.

"I didn't mean that! I just meant... well, then everything will be real. Just one kiss, you said. I can't see why that's so hard to arrange."

"The right kiss at the right time," said Lilith. "It has to be at the right time, otherwise it won't work." She smiled. He was trembling, partly out of lust, mainly out of terror, and slightly out of heredity.

"Don't worry," she said. "It can't not happen."

"And these witches you showed me?"

"They're just... part of the story. Don't worry about them. The story will just absorb them. And you'll get her because of stories. Won't that be nice? And now... shall we go? I expect you've got some ruling to do?"
