(Esk could get to grips with this. She had half-suspected it ever since she cleaned out the senior wizards’ lavatory, or ratherwhile the staff got on with the job while Esk examined the urinals and, with the assistance of some half-remembered details of her brothers in the tin bath in front of the fire at home, formulated her unofficial General Theory of comparative anatomy. The senior wizards’ lavatory was a magical place, with real running water and interesting tiles and, most importantly, two big silver mirrors fixed to opposite walls so that someone looking into one could see themselves repeated again and again until the image was too small to see. It was Esk’s first introduction to the idea of infinity. More to the point, she had a suspicion that one of the mirror Esks, right on the edge of sight, was waving at her.)

There was something disturbing about the phrases Simon used. Half the time he seemed to be saying that the world was about as real as a soap bubble, or a dream.

The chalk shrieked its way across the board behind him. Sometimes Simon had to stop and explain symbols to the wizards, who seemed to Esk to be getting excited at some very silly sentences. Then the chalk would start again, curving across the darkness like a comet, trailing its dust behind it.

The light was fading out of the sky outside. As the room grew more gloomy the chalked words glowed and the blackboard appeared to Esk to be not so much dark as simply not there at all, but just a square hole cut out of the world.

Simon talked on, about the world being made up of tiny things whose presence could only be determined by the fact that they were not there, little spinning balls of nothingness that magic could shunt together to make stars and butterflies and diamonds. Everything was made up of emptiness.

The funny thing was, he seemed to find this fascinating.

Esk was only aware that the walls of the room grew as thin and insubstantial as smoke, as if the emptiness in them was expanding to swallow whatever it was that defined them as walls, and instead there was nothing but the familiar cold, empty, glittering plain with its distant worn hills, and the creatures that stood as still as statues, looking down. There were a lot more of them now. They seemed for all the world to be clustering like moths around a light.

One important difference was that a moth’s face, even close up, was as friendly as a bunny rabbit’s compared to the things watching Simon.

Then a servant came in to light the lamps and the creatures vanished, turning into perfectly harmless shadows that lurked in the corners of the room.

At some time in the recent past someone had decided to brighten the ancient corridors of the University by painting them, having some vague notion that Learning Should Be Fun. It hadn’t worked. It’s a fact known throughout the universes that no matter how carefully the colours are chosen, institutional decor ends up as either vomit green, unmentionable brown, nicotine yellow or surgical appliance pink. By some little understood process of sympathetic resonance, corridors painted in those colours always smell slightly of boiled cabbage — even if no cabbage is ever cooked in the vicinity.

Somewhere in the corridors a bell rang. Esk dropped lightly from her windowsill, grabbed the staff and started to sweep industriously as doors were flung open and the corridors filled with students. They streamed past her on two sides, like water around a rock. For a few minutes there was utter confusion. Then doors slammed, a few laggard feet pattered away in the distance, and Esk was by herself again.

Not for the first time, Esk wished that the staff could talk. The other servants were friendly enough, but you couldn’t talk to them. Not about magic, anyway.

She was also coming to the conclusion that she ought to learn to read. This reading business seemed to be the key to wizard magic, which was all about words. Wizards seemed to think that names were the same as things, and that if you changed the name, you changed the thing. At least, it seemed to be something like that ….

Reading. That meant the library. Simon had said there were thousands of books in it, and amongst all those words there were bound to be one or two she could read. Esk put the staff over her shoulder and set off resolutely for Mrs Whitlow’s office.

She was nearly there when a wall said “Psst!” When Esk stared at it it turned out to be Granny. It wasn’t that Granny could make herself invisible, it was just that she had this talent for being able to fade into the foreground so that she wasn’t noticed.

“How are you getting on, then?” asked Granny. “How’s the magic coming along?”

“What are you doing here, Granny?” said Esk.

“Been to tell Mrs Whitlow her fortune,” said Granny, holding up a large bundle of old clothes with some satisfaction. Her smile faded under Esk’s stern gaze.

“Well, things are different in the city,” she said. “City people are always worried about the future, it comes from eating unnatural food. Anyway,” she added, suddenly realising that she was whining, “Why shouldn’t I tell fortunes?”

“You always said Hilta was playing on the foolishness of her sex,” said Esk. “You said that them as tell fortunes should be ashamed of themselves, and anyway, you don’t need old clothes.”

“Waste not, want not,” said Granny primly. She had spent her entire life on the old-clothes standard and wasn’t about to let temporary prosperity dislodge her: “Are you getting enough to eat?”

“Yes,” said Esk. “Granny, about this wizard magic, it’s all words—”

“Always said it was,” said Granny.

“No, I mean—” Esk began, but Granny waved a hand irritably.

“Can’t be bothered with this at the moment,” she said. “I’ve got some big orders to fill by tonight, if it goes on like this I’m going to have to train someone up. Can’t you come and see me when you get an afternoon off, or whatever it is they give you?”

“Train someone up?” said Esk, horrified. “You mean as a witch?”

“No,” said Granny. “I mean, perhaps.”

“But what about me?”

“Well, you’re going your own way,” said Granny. “Wherever that is.”

“Mmph,” said Esk. Granny stared at her.

“I’ll be off, then,” she said at last. She turned and strode off towards the kitchen entrance. As she did so her cloak swirled out, and Esk saw that it was now lined with red. A dark, winy red, but red nevertheless. On Granny, who had never been known to wear any visible clothing that was other than a serviceable black, it was quite shocking.

“The library?” said Mrs Whitlow. “Aye don’t think anyone cleans the library!” She looked genuinely puzzled.

“Why?” said Esk, “Doesn’t it get dusty?”

“Well,” said Mrs Whitlow. She thought for a while. “Aye suppose it must do, since you come to mention it. Aye never really thought about it.”

“You see, I’ve cleaned everywhere else,” said Esk, sweetly.

“Yes,” said Mrs Whitlow, “You have, haven’t you.”

“Well, then.”

“It’s just that we’ve never—done it before,” said Mrs Whitlow, “but for the life of me, Aye can’t think why.”

“Well, then,” said Esk.

“Ook?” said the Head Librarian, and backed away from Esk. But she had heard about him and had come prepared. She offered him a banana.

The orang-outan reached out slowly and then snatched it with a grin of triumph.

There may be universes where librarianship is considered a peaceful sort of occupation, and where the risks are limited to large volumes falling off the shelves on to one’s head, but the keeper of a magic library is no job for the unwary. Spells have power, and merely writing them down and shoving them between covers doesn’t do anything to reduce it. The stuff leaks. Books tend to react with one another, creating randomised magic with a mind of its own. Books of magic are usually chained to their shelves, but not to prevent them being stolen ….

One such accident had turned the librarian into an ape, since when he had resisted all attempts to turn him back, explaining in sign language that life as an orang-outan was considerably better than life as a human being, because all the big philosophical questions resolved themselves into wondering where the next banana was coming from. Anyway, long arms and prehensile feet were ideal for dealing with high shelves.

Esk gave him the whole bunch of bananas and scurried away amongst the books before he could object.

Esk had never seen more than one book at a time and so the library was, for all she knew, just like any other library. True, it was a bit odd the way the floor seemed to become the wall in the distance, and there was something strange about the way the shelves played tricks on the eyes and seemed to twist through rather more dimensions than the normal three, and it was quite surprising to look up and see shelves on the ceiling, with the occasional student wandering unconcernedly among them.

The truth was that the presence of so much magic distorted the space around it. Down in the stacks the very denim, or possibly flannelette, of the universe was tortured into very peculiar shapes. The millions of trapped words, unable to escape, bent reality around them.

It seemed logical to Esk that among all these books should be one that told you how to read all the others. She wasn’t sure how to find it, but deep in her soul she felt it would probably have pictures of cheerful rabbits and happy kittens on the cover.

The library certainly wasn’t silent. There was the occasional zip and sizzle of a magical discharge, and an octarine spark would flash from shelf to shelf. Chains clinked, faintly. And, of course, there was the faint rustle of thousands of pages in their leather-bound prisons.

Esk made sure no one was paying her any attention and pulled at the nearest volume. It sprang open in her hands, and she saw gloomily that there were the same unpleasant types of diagram that she had noticed in Simon’s book. The writing was entirely unfamiliar, and she was glad about that—it would be horrible to know what all those letters, which seemed to be made up of ugly creatures doing complicated things to each other, actually meant. She forced the cover shut, even though the words seemed to be desperately pushing back. There was a drawing of a creature on the front; it looked suspiciously like one of the things from the cold desert. It certainly didn’t look like a happy kitten.

“Hallo! Esk, isn’t it? H-how d-did you get h-here?”

It was Simon, standing there with a book under each arm. Esk blushed.

“Granny won’t tell me,” she said. “I think it’s something to do with men and women.”

Simon looked at her blankly. Then he grinned. Esk thought about the question a second time.

“I work here. I sweep up.” She waved the staff in explanation.

“In here?”

Esk stared at him. She felt alone, and lost, and more than a little betrayed. Everyone seemed to be busy living their own lives, except her. She would spend the rest of her life cleaning up after wizards. It wasn’t fair, and she’d had enough.

“Actually I don’t. Actually I’m learning to read so I can be a wizard.”

The boy regarded her through his damp eyes for some seconds. Then he gently took the book out of Esk’s hands and read its title.

“Demonylogie Malyfycorum of Henchanse thee Unsatyfactory. How did you think you could learn to r-read this?”

“Um,” said Esk, “Well, you just keep trying until you can, don’t you? Like milking, or knitting, or . . . .” Her voice faded away.

“I don’t know about that. These books can be a bit, well, aggressive. If you d-don’t be careful they start reading you.”

“What do you mean?”

“T-they ssss—”

“—say—”said Esk, automatically.

“—that there was once a wwww—”

“—wizard—”

“—who started to r-read the Necrotelecomnicon and let his m-mind wwwwww—”

“—wander—”

“—and next morning they f-found all his clothes on the chair and hhis hat on t-top of them and the b-book had—”

Esk put her fingers in her ears, but not too hard in case she missed anything.

“I don’t want to know about it if it’s horrid.”

“—had a lot more pages.”

Esk took her fingers out of her ears. “Was there anything on the pages?”

Simon nodded solemnly. “Yes. On every sssingle one of ththem there www—”

“No,” said Esk. “I don’t even want to imagine it. I thought reading was more peaceful than that, I mean, Granny read her Almanack every day and nothing ever happened to her.”

“I d-daresay ordinary tame www—”

“—words—”

“—are all right,” Simon conceded, magnanimously.

“Are you absolutely certain?” said Esk.

“It’s just that words can have power,” said Simon, slotting the book firmly back on its shelf, where it rattled its chains at him. “And they do say the p-pen is mightier than the sss—”

“—sword,” said Esk. “All right, but which would you rather be hit with?”

“Um, I d-don’t think it’s any use m-me t-telling you you shouldn’t be in here, is it?” said the young wizard.

Esk gave this due consideration. “No,” she said, “I don’t think it is.”

“I could send for the p-porters and have you t-taken away.”

“Yes, but you won’t.”

“I just d-don’t www—”

“—want—”

“—you to get hurt, you see. I r-really don’t. This can b-be a ddddangerou—”

Esk caught a faint swirling in the air above his head. For a moment she saw them, the great grey shapes from the cold place. Watching. And in the calm of the Library, when the weight of magic was wearing the Universe particularly thin, they had decided to Act.

Around her the muted rustling of the books rose to a desperate riffling of pages. Some of the more powerful books managed to jerk out of their shelves and swung, flapping madly, from the end of their chains. A huge grimoire plunged from its eyrie on the topmost shelf—tearing itself free of its chain in the process—and flopped away like a frightened chicken, scattering its pages behind it.

A magical wind blew away Esk’s headscarf and her hair streamed out behind her. She saw Simon trying to steady himself against a bookshelf as books exploded around him. The air was thick and tasted of tin. It buzzed.

“They’re trying to get in!” she screamed.

Simon’s tortured face turned to her. A fear-crazed incunable hit him heavily in the small of the back and knocked him to the heaving floor before it bounced high over the shelves. Esk ducked as a flock of thesauri wheeled past, towing their shelf behind them, and scuttled on hands and knees towards him.

“That’s what’s making the books so frightened!” she shrieked in his ear. “Can’t you see them up there?”

Simon mutely shook his head. A book burst its bindings over them, showering them in pages.

Horror can steal into the mind via all the senses. There’s the sound of the little meaningful chuckle in the locked dark room, the sight of half a caterpillar in your forkful of salad, the curious smell from the lodger’s bedroom, the taste of slug in the cauliflower cheese. Touch doesn’t normally get a look-in.

But something happened to the floor under Esk’s hands. She looked down, her face a rictus of horror, because the dusty floorboards suddenly felt gritty. And dry. And very, very cold.

There was fine silver sand between her fingers.

She grabbed the staff and, sheltering her eyes against the wind, waved it at the towering figures above her. It would have been nice to report that a searing flash of pure white fire cleansed the greasy air. It failed to materialise ….

The staff twisted like a snake in her hand and caught Simon a crack on the side of the head.

The grey Things wavered and vanished.

Reality returned, and tried to pretend that it had never left. Silence settled like thick velvet, wave after wave of it. A heavy, echoing silence. A few books dropped heavily out of the air, feeling silly.

The floor under Esk’s feet was undoubtedly wooden. She kicked it hard to make sure.

There was blood on the floor, and Simon lay very quietly in the centre of it. Esk stared down at him, and then up at the still air, and then at the staff. It looked smug.

She was aware of distant voices and hurrying feet.

A hand like a fine leather glove slipped gently into hers and a voice behind said “Ook,” very softly. She turned, and found herself staring down into the gentle, inner-tube face of the librarian. He put his finger to his lips in an unmistakable gesture and tugged gently at her hand.

“I’ve killed him!” she whispered.

The librarian shook his head, and tugged insistently.

“Ook,” he explained, “Ook.”

He dragged her reluctantly down a side alley-way in the maze of ancient shelving a few seconds before a party of senior wizards, drawn by the noise, rounded the corner.

“The books have been fighting again . . . .”

“Oh, no! It’ll take ages to capture all the spells again, you know they go and find places to hide . . . .”

“Who’s that on the floor?”

There was a pause.

“He’s knocked out. A shelf caught him, by the looks of it.”

“Who is he?”

“That new lad. You know; the one they say has got a whole head full of brains?”

“If that shelf had been a bit closer we’d be able to see if they were right.”

“You two, get him along to the infirmary. The rest of you better get these books rounded up. Where’s the damn librarian? He ought to know better than to let a Critical Mass build up.”

Esk glanced sideways at the orang-outan, who waggled his eyebrows at her. He pulled a dusty volume of gardening spells out of the shelves beside him, extracted a soft brown banana from the recess behind it, and ate it with the quiet relish of one who knows that whatever the problems are, they belong firmly to human beings.

She looked the other way, at the staff in her hand, and her lips went thin. She knew her grip hadn’t slipped. The staff had lunged at Simon, with murder in its heartwood.

The boy lay on a hard bed in a narrow room, a cold towel folded across his forehead. Treatle and Cutangle watched him carefully.

“How long has it been?” said Cutangle.

Trestle shrugged. “Three days.”

“And he hasn’t come around once?”

“No.”

Cutangle sat down heavily on the edge of the bed, and pinched the bridge of his nose wearily. Simon had never looked particularly healthy, but now his face had a horrible sunken look.

“A. brilliant mind, that one,” he said. “His explanation of the fundamental principles of magic and matter—quite astounding.”

Trestle nodded.

“The way he just absorbs knowledge,” said Cutangle: “I’ve been a working wizard all my life, and somehow I never really understood magic until he explained it. So clear. So, well, obvious.”

“Everyone says that,” said Trestle gloomily. “They say it’s like having a hoodwink pulled off and seeing the daylight for the first time.”

“That’s exactly it,” said Cutangle, “He’s sourcerer material, sure enough. You were right to bring him here.”

There was a thoughtful pause.

“Only—”said Trestle.

“Only what?” asked Cutangle.

“Only what was it you understood?” said Trestle. “That’s what’s bothering me. I mean, can you explain it?”

“How do you mean, explain?” Cutangle looked worried.

“What he keeps talking about,” said Trestle, a hint of desperation in his voice. “Oh, it’s the genuine stuff, I know. But what exactly is it?”

Cutangle looked at him, his mouth open. Eventually he said, “Oh, that’s easy. Magic fills the universe, you see, and every time the universe changes, no, I mean every time magic is invoked, the universe changes, only in every direction at once, d’you see, and—” he moved his hands uncertainly, trying to recognise a spark of comprehension in Trestle’s face. “To put it another way, any piece of matter, like an orange or the world or, or—”

“—a crocodile?” suggested Trestle.

“Yes, a crocodile, or—whatever, is basically shaped like a carrot.”

“I don’t remember that bit,” said Trestle.

“I’m sure that’s what he said,” said Cutangle. He was starting to sweat.

“No, I remember the bit where he seemed to suggest that if you went far enough in any direction you would see the back of your head,” Trestle insisted.

“You’re sure he didn’t mean someone else’s head?”

Trestle thought for a bit.

“No, I’m pretty sure he said the back of your own head,” he said. “I think he said he could prove it.”

They considered this in silence.

Finally Cutangle spoke, very slowly and carefully.

“I look at it all like this,” he said. “Before I heard him talk, I was like everyone else. You know what I mean? I was confused and uncertain about all the little details of life. But now,” he brightened up, “while I’m still confused and uncertain it’s on a much higher plane, d’you see, and at least I know I’m bewildered about the really fundamental and important facts of the universe.”

Trestle nodded. “I hadn’t looked at it like that,” he said, “but you’re absolutely right. He’s really pushed back the boundaries of ignorance. There’s so much about the universe we don’t know.”

They both savoured the strange warm glow of being much more ignorant than ordinary people, who were ignorant of only ordinary things.

Then Trestle said: “I just hope he’s all right. He’s over the fever but he just doesn’t seem to want to wake up.”

A couple of servants came in with a bowl of water and fresh towels. One of them carried a rather tatty broomstick. As they began to change the sweat-soaked sheets under the boy the two wizards left, still discussing the vast vistas of unknowingness that Simon’s genius had revealed to the world.

Granny waited until their footsteps had died away and took off her headscarf.

“Damn thing,” she said. “Esk, go and listen at the door.” She removed the towel from Simon’s head and felt his temperature.

“It was very good of you to come,” said Esk. “And you so busy with your work, and everything.”

“Mmmph.” Granny pursed her lips. She pulled up Simon’s eyelids and sought his pulse. She laid an ear on his xylophone chest and listened to his heart. She sat for some time quite motionless, probing around inside his head.

She frowned.

“Is he all right?” said Esk anxiously.

Granny looked at the stone walls.

“Drat this place,” she said. “It’s no place for sick people.”

“Yes, but is he all right?”

“What?” Granny was startled out of her thoughts. “Oh. Yes. Probably. Wherever he is.”

Esk stared at her, and then at Simon’s body.

“Nobody’s home,” said Granny, simply.

“What do you mean?”

“Listen to the child,” said Granny. “You’d think I taught her nothing. I mean his mind’s Wandering. He’s gone Out of his Head.”

She looked at Simon’s body with something verging on admiration.

“Quite surprisin’, really,” she added. “I never yet met a wizard who could Borrow.”

She turned to Esk, whose mouth was a horrified O.

“I remember when I was a girl, old Nanny Annaple went Wanderin’. Got too wrapped up with being a vixen, as I recall. Took us days to find her. And then there was you, too. I never would have found you if it wasn’t for that staff thing, and what have you done with it, girl?”

“It hit him,” Esk muttered. “It tried to kill him. I threw it in the river.”

“Not a nice thing to do to it after it saved you,” said Granny.

“It saved me by hitting him?”

“Didn’t you realise? He was callin’ to—them Things.”

“That’s not true!”

Granny stared into Esk’s defiant eyes and the thought came to her mind: I’ve lost her. Three years of work down the privy. She couldn’t be a wizard but she might have been a witch.

“Why isn’t it true, Miss Clever?” she said.

“He wouldn’t do something like that!” Esk was near to tears. “I heard him speak, he’s—well, he’s not evil, he’s a brilliant person, he nearly understands how everything works, he’s—”

“I expect he’s a very nice boy,” said Granny sourly. “I never said he was a black wizard, did I?”

“They’re horrible Things!” Esk sobbed. “He wouldn’t call out to them, he wants everything that they’re not, and you’re a wicked old—”

The slap rang like a bell. Esk staggered back, white with shock. Granny stood with her hand upraised, trembling.

She’d struck Esk once before—the blow a baby gets to introduce it to the world and give it a rough idea of what to expect from life. But that had been the last time. In three years under the same roof there had been cause enough, when milk had been left to boil over or the goats had been carelessly left without water, but a sharp word or a sharper silence had done more than force ever could and left no bruises.

She grabbed Esk firmly by the shoulders and stared into her eyes.

“Listen to me,” she said urgently. “Didn’t I always say to you that if you use magic you should go through the world like a knife goes through water? Didn’t I say that?”

Esk, mesmerised like a cornered rabbit, nodded.

“And you thought that was just old Granny’s way, didn’t you? But the fact is that if you use magic you draw attention to yourself. From Them. They watch the world all the time. Ordinary minds are just vague to them, they hardly bother with them, but a mind with magic in it shines out, you see, it’s a beacon to them. It’s not darkness that calls Them, it’s light, light that creates the shadows!”

“But—but—why are They interested? What do They wwant?”

“Life and shape,” said Granny.

She sagged, and let go of Esk.

“They’re pathetic, really,” she said. “They’ve got no life or shape themselves but what they can steal. They could no more survive in this world than a fish could live in a fire, but that doesn’t stop them trying. And they’re just bright enough to hate us because we’re alive.”

Esk shivered. She remember the gritty feel of the cold sand.

“What are They? I always thought they were just a sort—a sort of demon?”

“Nah. No one really knows. They’re just the Things from the Dungeon Dimensions outside the universe, that’s all. Shadow creatures.”

She turned back to the prone form of Simon.

“You wouldn’t have any idea where he is, would you?” she said, looking shrewdly at Esk. “Not gone off flying with the seagulls, has he?”

Esk shook her head.

“No,” said Granny, “I didn’t think so. They’ve got him, haven’t they.”

It wasn’t a question. Esk nodded, her face a mask of misery.

“It’s not your fault,” said Granny, “His mind gave them an opening, and when he was knocked out they took it back with them. Only. . . .”

She drummed her fingers on the edge of the bed, and appeared to reach a decision.

“Who’s the most important wizard around here?” she demanded.

“Um, Lord Cutangle,” said Esk. “He’s the Archchancellor. He was one of the ones who was in here.”

“The fat one, or the one like a streak of vinegar?”

Esk dragged her mind from the image of Simon on the cold desert and found herself saying: “He’s an Eighth Level wizard and a 33-degree mage, actually.”

“You mean he’s bent?” said Granny. “All this hanging around wizards has made you take them seriously, my girl. They all call themselves the Lord High this and the Imperial That, it’s all part of the game. Even magicians do it, you’d think they’d be more sensible at least, but no, they call around saying they’re the Amazing-Bonko-and-Doris. Anyway, where is this High Rumtiddlypo?”

“They’ll be at dinner in the Great Hall,” said Esk. “Can he bring Simon back, then?”

“That’s the difficult part,” said Granny. “I daresay we could all get something back easily enough, walking and talking just like anyone. Whether it would be Simon is quite another sack of ferrets.”

She stood up. “Let’s find this Great Hall, then. No time to waste.”

“Um, women aren’t allowed in,” said Esk.

Granny stopped in the doorway. Her shoulders rose. She turned around very slowly.

“What did you say?” she said. “Did these old ears deceive me, and don’t say they did because they didn’t.”

“Sorry,” said Esk. “Force of habit.”

“I can see you’ve been getting ideas below your station,” said Granny coldly. “Go and find someone to watch over the lad, and let’s see what’s so great about this hall that I mustn’t set foot in it.”

And thus it was that while the entire faculty of Unseen University were dining in the venerable hall the doors were flung back with a dramatic effect that was rather spoiled when one of them rebounded off a waiter and caught Granny a crack on the shin. Instead of the defiant strides she had intended to make across the chequered floor she was forced to half-hop, half-limp. But she hoped that she hopped with dignity.

Esk hurried along behind her, acutely aware of the hundreds of eyes that were turned towards them.

The roar of conversation and the clatter of cutlery faded away. A couple of chairs were knocked over. At the far end of the hall she could see the most senior wizards at their high table, which in fact bobbed a few feet off the floor. They were staring.

A medium-grade wizard—Esk recognised him as a lecturer in Applied Astrology—rushed towards them, waving his hands.

“Nononono,” he shouted. “Wrong door. You must go away.”

“Don’t mind me,” said Granny calmly, pushing past him.

“Nonono, it’s against the lore, you must go away now. Ladies are not allowed in here!”

“I’m not a lady, I’m a witch,” said Granny. She turned to Esk. “Is he very important?”

“I don’t think so,” said Esk.

“Right.” Granny turned to the lecturer: “Go and find me an important wizard, please. Quickly.”
