‘Trousers?’

‘They’re not exactly the same as ordinary—’

‘And there’s men ’ere lookin’,’ said Granny. ‘I think it’s shameful!’

‘What is?’ said Nanny Ogg, coming up behind her.

‘Magrat Garlick, standin’ there bifurcated,’ said Granny, sticking her nose in the air.

‘Just so long as she got the young man’s name and address,’ said Nanny Ogg amiably.

‘Nanny!’ said Magrat.

‘I think they look quite comfy,’ Nanny went on. ‘A bit baggy, though.’

‘I don’t ’old with it,’ said Granny. ‘Everyone can see her legs.’

‘No they can’t,’ said Nanny. ‘The reason being, the material is in the way.’

‘Yes, but they can see where her legs are,’ said Granny Weatherwax.

‘That’s silly. That’s like saying everyone’s naked under their clothes,’ said Magrat.

‘Magrat Garlick, may you be forgiven,’ said Granny Weatherwax.

‘Well, it’s true!’

‘I’m not,’ said Granny flatly, ‘I got three vests on.’

She looked Nanny up and down. Gytha Ogg, too, had made sartorial preparations for foreign parts. Granny Weatherwax could find little to disapprove of, although she made an effort.

‘And will you look at your hat,’ she mumbled. Nanny, who had known Esme Weatherwax for seventy years, merely grinned.

‘All the go, ain’t it?’ she said. ‘Made by Mr Vernissage over in Slice. It’s got willow reinforcing all the way up to the point and eighteen pockets inside. Can stop a blow with a hammer, this hat. And how about these?’

Nanny raised the hem of her skirt. She was wearing new boots. As boots, Granny Weatherwax could find nothing to complain of in them. They were of proper witch construction, which is to say that a loaded cart could have run over them without causing a dent in the dense leather. As boots, the only thing wrong with them was the colour.

‘Red?’ said Granny. ‘That’s no colour for a witch’s boots!’

‘I likes ’em,’ said Nanny.

Granny sniffed. ‘You can please yourself, I’m sure,’ she said. ‘I’m sure in foreign parts they goes in for all sorts of outlandish things. But you know what they say about women who wear red boots.’

‘Just so long as they also say they’ve got dry feet,’ said Nanny cheerfully. She put her door key into Jason’s hand.

‘I’ll write you letters if you promise to find someone to read them to you,’ she said.

‘Yes, mum. What about the cat, mum?’ said Jason.

‘Oh, Greebo’s coming with us,’ said Nanny Ogg.

‘What? But he’s a cat!’ snapped Granny Weatherwax. ‘You can’t take cats with you! I’m not going travellin’ with no cat! It’s bad enough travellin’ with trousers and provocative boots!’

‘He’ll miss his mummy if he’s left behind, won’t he,’ crooned Nanny Ogg, picking up Greebo. He hung limply, like a bag of water gripped around the middle.

To Nanny Ogg Greebo was still the cute little kitten that chased balls of wool around the floor.

To the rest of the world he was an enormous tomcat, a parcel of incredibly indestructible life forces in a skin that looked less like a fur than a piece of bread that had been left in a damp place for a fortnight. Strangers often took pity on him because his ears were non-existent and his face looked as though a bear had camped on it. They could not know that this was because Greebo, as a matter of feline pride, would attempt to fight or rape absolutely anything, up to and including a four-horse logging wagon. Ferocious dogs would whine and hide under the stairs when Greebo sauntered down the street. Foxes kept away from the village. Wolves made a detour.

‘He’s an old softy really,’ said Nanny.

Greebo turned upon Granny Weatherwax a yellow-eyed stare of self-satisfied malevolence, such as cats always reserve for people who don’t like them, and purred. Greebo was possibly the only cat who could snigger in purr.

‘Anyway,’ said Nanny, ‘witches are supposed to like cats.’

‘Not cats like him, they’re not.’

‘You’re just not a cat person, Esme,’ said Nanny, cuddling Greebo tightly.

Jason Ogg pulled Magrat aside.

‘Our Sean read to me in the almanac where there’s all these fearsome wild beasts in foreign parts,’ he whispered. ‘Huge hairy things that leap out on travellers, it said. I’d hate to think what’d happen if they leapt out on mum and Granny.’

Magrat looked up into his big red face.

‘You will see no harm comes to them, won’t you,’ said Jason.

‘Don’t you worry,’ she said, hoping that he needn’t. ‘I’ll do my best.’

Jason nodded. ‘Only it said in the almanac that some of them were nearly extinct anyway,’ he said.

The sun was well up when the three witches spiralled into the sky. They had been delayed for a while because of the intractability of Granny Weatherwax’s broomstick, the starting of which always required a great deal of galloping up and down. It never seemed to get the message until it was being shoved through the air at a frantic running speed. Dwarf engineers everywhere had confessed themselves totally mystified by it. They had replaced the stick and the bristles dozens of times.

When it rose, eventually, it was to a chorus of cheers.

The tiny kingdom of Lancre occupied little more than a wide ledge cut into the side of the Ramtop mountains. Behind it, knife-edge peaks and dark winding valleys climbed into the massive backbone of the central ranges.

In front, the land dropped abruptly to the Sto plains, a blue haze of woodlands, a broader expanse of ocean and, somewhere in the middle of it all, a brown smudge known as Ankh-Morpork.

A skylark sang, or at least started to sing. The rising point of Granny Weatherwax’s hat right underneath it completely put it off the rhythm.

‘I ain’t going any higher,’ she said.

‘If we go high enough we might be able to see where we’re going,’ said Magrat.

‘You said you looked at Desiderata’s maps,’ said Granny.

‘It looks different from up here, though,’ said Magrat. ‘More … sticking up. But I think we go … that way.’

‘You sure?’

Which was the wrong question to ask a witch. Especially if the person doing the asking was Granny Weatherwax.

‘Positive,’ said Magrat.

Nanny Ogg looked up at the high peaks.

‘There’s a lot of big mountains that way,’ she said.

They rose tier on tier, speckled with snow, trailing endless pennants of ice crystals high overhead. No-one ski’d in the high Ramtops, at least for more than a few feet and a disappearing scream. No-one ran up them wearing dirndls and singing.^{15} They were not nice mountains. They were the kind of mountains where winters went for their summer holidays.

‘There’s passes and things through them,’ said Magrat uncertainly.

‘Bound to be,’ said Nanny.

You can use two mirrors like this, if you know the way of it: you set them so that they reflect each other. For if images can steal a bit of you, then images of images can amplify you, feeding you back on yourself, giving you power …

And your image extends forever, in reflections of reflections of reflections, and every image is the same, all the way around the curve of light.

Except that it isn’t.

Mirrors contain infinity.

Infinity contains more things than you think.

Everything, for a start.

Including hunger.

Because there’s a million billion images and only one soul to go around.

Mirrors give plenty, but they take away lots.

Mountains unfolded to reveal more mountains. Clouds gathered, heavy and grey.

‘I’m sure we’re going the right way,’ said Magrat. Freezing rock stretched away. The witches flew along a maze of twisty little canyons, all alike.^{16}

‘Yeah,’ said Granny.

‘Well, you won’t let me fly high enough,’ said Magrat.

‘It’s going to snow like blazes in a minute,’ said Nanny Ogg.

It was early evening. Light was draining out of the high valleys like custard.

‘I thought … there’d be villages and things,’ said Magrat, ‘where we could buy interesting native produce and seek shelter in rude huts.’

‘You wouldn’t even get trolls up here,’ said Granny.

The three broomsticks glided down into a bare valley, a mere notch in the mountain side.

‘And it’s bloody cold,’ said Nanny Ogg. She grinned. ‘Why’re they called rude huts, anyway?’

Granny Weatherwax climbed off her broomstick and looked at the rocks around her. She picked up a stone and sniffed it. She wandered over to a heap of scree that looked like any other heap of scree to Magrat, and prodded it.

‘Hmm,’ she said.

A few snow crystals landed on her hat.

‘Well, well,’ she said.

‘What’re you doing, Granny?’ said Magrat.

‘Cogitatin’.’

Granny walked to the valley’s steep side and strolled along it, peering at the rock. Nanny Ogg joined her.

‘Up here?’ said Nanny.

‘I reckon.’

‘’S a bit high for ’em, ain’t it?’

‘Little devils get everywhere. Had one come up in my kitchen once,’ said Granny. ‘“Following a seam”, he said.’

‘They’re buggers for that,’ said Nanny.

‘Would you mind telling me,’ said Magrat, ‘what you’re doing? What’s so interesting about heaps of stones?’

The snow was falling faster now.

‘They ain’t stones, they’re spoil,’ said Granny. She reached a flat wall of ice-covered rock, no different in Magrat’s eyes from the rock available in a range of easy-to-die-on sizes everywhere in the mountains, and paused as if listening.

Then she stood back, hit the rock sharply with her broomstick, and spake thusly:

‘Open up, you little sods!’^{17}

Nanny Ogg kicked the rock. It made a hollow boom.

‘There’s people catching their death of cold out here!’ she added.

Nothing happened for a while. Then a section of rock swung in a few inches. Magrat saw the glint of a suspicious eye.

‘Yes?’

‘Dwarfs?’ said Magrat.

Granny Weatherwax leaned down until her nose was level with the eye.

‘My name,’ she said, ‘is Granny Weatherwax.’

She straightened up again, her face glowing with self-satisfaction.

‘Who’s that, then?’ said a voice from somewhere below the eye. Granny’s expression froze.

Nanny Ogg nudged her partner.

‘We must be more’n fifty miles away from home,’ she said. ‘They might not have heard of you in these parts.’

Granny leaned down again. Accumulated snowflakes cascaded off her hat.

‘I ain’t blaming you,’ she said, ‘but I know you’ll have a King in there, so just you go and tell him Granny Weatherwax is here, will you?’

‘He’s very busy,’ said the voice. ‘We’ve just had a bit of trouble.’

‘Then I’m sure he don’t want any more,’ said Granny.

The invisible speaker appeared to give this some consideration.

‘We put writing on the door,’ it said sulkily. ‘In invisible runes. It’s really expensive, getting proper invisible runes done.’

‘I don’t go around readin’ doors,’ said Granny.

The speaker hesitated.

‘Weatherwax, did you say?’

‘Yes. With a W. As in “witch”.’

The door slammed. When it was shut, there was barely a visible crack in the rock.

The snow was falling fast now. Granny Weatherwax jiggled up and down a bit to keep warm.

‘That’s foreigners for you,’ she said, to the frozen world in general.

‘I don’t think you can call dwarfs foreigners,’ said Nanny Ogg.

‘Don’t see why not,’ said Granny. ‘A dwarf who lives a long way off has got to be foreign. That’s what foreign means.’

‘Yeah? Funny to think of it like that,’ said Nanny.

They watched the door, their breath forming three little clouds in the darkening air. Magrat peered at the stone door.

‘I didn’t see any invisible runes,’ she said.

‘’Corse not,’ said Nanny. ‘That’s ’cos they’re invisible.’

‘Yeah,’ said Granny Weatherwax. ‘Don’t be daft.’

The door swung open again.

‘I spoke to the King,’ said the voice.

‘And what did he say?’ said Granny expectantly.

‘He said, “Oh, no! Not on top of everything else!”’

Granny beamed. ‘I knew ’e would have heard of me,’ she said.

In the same way that there are a thousand Kings of the Gypsies, so there are a thousand Kings of the Dwarfs. The term means something like ‘senior engineer’. There aren’t any Queens of the Dwarfs. Dwarfs are very reticent about revealing their sex, which most of them don’t consider to be very important compared to things like metallurgy and hydraulics.

This king was standing in the middle of a crowd of shouting miners. He^[10] looked up at the witches with the expression of a drowning man looking at a drink of water.

‘Are you really any good?’ he said.

Nanny Ogg and Granny Weatherwax looked at one another.

‘I think ‘e’s talking to you, Magrat,’ said Granny.

‘Only we’ve had a big fall in gallery nine,’ said the King. ‘It looks bad. A very promising vein of gold-bearing quartz is irretrievably trapped.’

One of the dwarfs beside him muttered something.

‘Oh, yeah. And some of the lads,’ said the King vaguely. ‘And then you turn up. So the way I look at it, it’s probably fate.’

Granny Weatherwax shook the snow off her hat and looked around.

She was impressed, despite herself. You didn’t often see proper dwarf halls these days. Most dwarfs were off earning big money in the cities down in the lowlands, where it was much easier to be a dwarf — for one thing, you didn’t have to spend most of your time underground hitting your thumb with a hammer and worrying about fluctuations in the international metal markets. Lack of respect for tradition, that was the trouble these days. And take trolls. There were more trolls in Ankh-Morpork now than in the whole mountain range. Granny Weatherwax had nothing against trolls but she felt instinctively that if more trolls stopped wearing suits and walking upright, and went back to living under bridges and jumping out and eating people as nature intended, then the world would be a happier place.

‘You’d better show us where the problem is,’ she said. ‘Lots of rocks fallen down, have they?’

‘Pardon?’ said the King.

It’s often said that eskimos have fifty words for snow.^[11]

This is not true.^{18}

It’s also said that dwarfs have two hundred words for rock.

They don’t. They have no words for rock, in the same way that fish have no words for water. They do have words for igneous rock, sedimentary rock, metamorphic rock, rock underfoot, rock dropping on your helmet from above, and rock which looked interesting and which they could have sworn they left here yesterday. But what they don’t have is a word meaning ‘rock’. Show a dwarf a rock and he sees, for example, an inferior piece of crystalline sulphite of barytes.

Or, in this case, about two hundred tons of lowgrade shale. When the witches arrived at the disaster site dozens of dwarfs were working feverishly to prop the cracked roof and cart away the debris. Some of them were in tears.

‘It’s terrible … terrible,’ muttered one of them. ‘A terrible thing.’

Magrat lent him her handkerchief. He blew his nose noisily.
