Cat trailed forlornly back to the schoolroom to find them having Geography. Mr. Saunders was raging at Janet for not knowing where Atlantis was.

"How was I to know it's what I call America?" Janet asked Cat at lunchtime. "Though, mind you, that was a lucky guess when I said it was ruled by the Incas. What's the matter, Cat? You look ready to cry.

He's not found out about Mr. Biswas, has he?"

"No, but it's quite as bad," said Cat, and he explained.

"This was all we needed!" said Janet. "Discovery threatens on all sides. But it may not be quite as bad as it seems, when I think. You might be able to work up a little magic if you practiced first. Let's see what we can do after school with Gwendolen's books that the dear, kind girl so obligingly left us." Cat was quite glad when lessons started again. He was sick of changing plates with Janet, and Julia's handkerchief must have been worn to rags with the number of knots tied in it. After lessons, he and Janet collected the two magic books and took them up to Cat's room. Janet looked around it with admiration.

"I like this room much better than mine. It's cheerful. Mine makes me feel like the Sleeping Beauty and Cinderella, and they were both such sickeningly sweet girls. Now let's get down to work. What's a really simple spell?"

They knelt on the floor, leafing through a book each. "I wish I could find how to turn b.u.t.tons into sovereigns," said Cat. "We could pay Mr. Baslam then."

"Don't talk about it," said Janet. "I'm at our wits' end. How about this? 'Simple flotation exercise. Take a small mirror and lay it so that your face is visible in it. Keeping face visible, move around widder-shins three times, twice silently willing, the third time saying: "Rise little mirror, rise in air, rise to my head and then stay there." Mirror should then rise-' I think you ought to be able to manage that, Cat."

"I'll have a go," Cat said dubiously. "What's widdershins?"

"Anticlockwise," said Janet. "That I do know."

"I thought it meant crawling," Cat said humbly.

Janet looked at him consideringly. "I suppose you're quite small still," she said, "but you do worry me when you go all cowed. Has anyone done anything to you?"

"I don't think so," Cat said, rather surprised. "Why?"

"Well, I never had a brother," said Janet. "Fetch a mirror."

Cat got the hand mirror from his chest of drawers and laid it carefully in the middle of the floor. "Like that?"

Janet sighed. "That's what I mean. I knew you'd get it if I ordered you to. Do you mind not being so kind and obedient? It makes me nervous. Anyway-" She took up the book. "Can you see your face in it?"

"Almost nothing else," said Cat.

"Funny. I can see my face," said Janet. "Can I do it, too?"

"You're more likely to get it to work than I am," said Cat.

So they both circled the mirror, and they said the words in chorus. The door opened. Mary came in.

Janet guiltily put the book behind her back.

"Yes, here he is," Mary said. She stood aside to let a strange young man come into the room. "This is Will Suggins," she said. "He's Euphemia's young man. He wants to talk to you, Eric."

Will Suggins was tall and burly and rather handsome. His clothes looked as if he had brushed them carefully after working in a bakery all day. He was not friendly. "It was you turned Euphemia into a frog, was it?" he said to Cat.

"Yes," said Cat. He dared say nothing else with Mary there.

"You're rather small," said Will Suggins. He seemed disappointed about it. "Anyway," he said, "whateversize you are, I'm not having Euphemia turned into things. I take exception to it. Understand ?"

"I'm very sorry," said Cat. "I won't do it again."

"Too right you won't!" said Will Suggins. "You got off too light over this, by what Mary tells me. I'm going to teach you a lesson you won't forget in a hurry."

"No you're not!" said Janet. She marched up to Will Suggins and pushed Magic for Beginners threateningly towards him. "You're three times his size, and he's said he's sorry. If you touch Cat, I shall-" She took the book out of Will Suggins' chest in order to leaf hastily through it. "I shall induce complete immobility in the legs and trunk."

"And very pretty I shall look, I'm sure!" Will Suggins said, much amused. "How are you going to do that without your witchcraft, may I ask? And if you did, I daresay I could get out of it fast enough. I'm a fair warlock myself. Though," he said, turning to Mary, "you might have warned me he was this small."

"Not so small where witchcraft and mischief are concerned," said Mary. "Neither of them are. They're a pair of real bad lots."

"Well, I'll do it by witchcraft then. I'm easy," said Will Suggins. He searched in the pockets of his slightly floury jacket. "Ah!" he said, and fetched out what seemed to be a lump of dough. For a moment he shaped it vigorously in both powerful hands. Then he rolled it into a ball and threw it at Cat's feet. It landed on the carpet with a soft plop. Cat looked at it in great apprehension, wondering what it was supposed to do.

"That'll lie there," said Will Suggins, "until three o'clock Sunday. Sunday's a bad time to be at witchcraft, but it's my free day. I shall be waiting for you then in Bedlam Field, in the form of a tiger. I make a good tiger. You can turn yourself into something as large as you like, or small and fast, if you prefer, and I'll teach you that lesson whatever you are. But if you don't come to Bedlam Field in the form of something, that lump of dough will start to work and you'll be a frog yourself-for as long as I feel like keeping you that way. Right, Mary. I'm through now."

Will Suggins turned and marched out of the room. Mary followed him, but she was unable to resist putting her head back around the door to say, "And see how you like that, Eric!" before she shut it.

Cat and Janet looked at one another and then at the lump of dough. "What am I going to do?" said Cat.

Janet threw her book onto Cat's bed and tried to pick up the lump of dough. But it had grown to the carpet. She could not shift it. "You'd only get this up by cutting a hole in the floor," she said. "Cat, this gets worse and worse. If you'll forgive my saying so, I've stopped loving your sugar-coated sister even one tiny bit!"

"It was my fault," said Cat. "I shouldn't have lied about Euphemia. That's what got me in this mess, not Gwendolen."

"Mess is not a strong enough word," said Janet. "On Sunday, you get mauled by a tiger. On Monday, it comes out that you can't do magic. And if the whole story doesn't come out then, it will on Wednesday, when Mr. Bedlam calls for his money. Do you think Fate has something up its sleeve for Tuesday too? I suppose if you go to meet him on Sunday in the form of yourself, he can't hurt you much, can he? It's better than waiting to be turned into a frog."

"I'd better do that," Cat agreed, looking at that ominous lump of dough. "I wish I really could turn into things, though. I'd go as a flea. He'd scratch himself to bits trying to find me." Janet laughed. "Let's see if there's a spell for it." She turned around to fetch Magic for Beginners and hit her head on the mirror. It was hanging in the air, level with her forehead. "Cat! One of us did it! Look!"

Cat looked, without much interest. He had too much else on his mind. "I expect it was you. You're the same as Gwendolen, so you're bound to be able to work spells. But changing into things won't be in either of those books. That's Advanced Magic."

"Then I'll do the spell to get the mirror down," said Janet. "Not that I want to be a witch. The more I see of witchcraft, the more it seems just an easy way to be nasty."

She had opened the book, when there was a knock at the door. Janet seized the chair beside Cat's bed and stood on it, so as to hide the mirror. Cat hastily dropped to one knee on top of the lump of dough.

Neither of them wanted any more trouble.

Janet doubled Magic for Beginners inside out so that it could have been any book, and waved it at Cat.

"'Come into the garden, Maud,'" she proclaimed.

Taking this as an invitation, Miss Bessemer opened the door and came in. She was carrying an armful of things, with a chipped teapot hanging off one finger. "The furnishings I promised you, loves," she said.

"Oh," said Janet. "Oh, thanks very much. We were just having a poetry reading, you know."

"And I made sure you were talking to me!" Miss Bessemer said, laughing. "My name's Maud. Will these be all right on the bed?"

"Yes, thanks," said Cat.

Neither of them dared move. They twisted around to watch Miss Bessemer dump the armful on the bed and, still twisted, they thanked her profusely. As soon as Miss Bessemer had gone, they dived to see if, by any blessed chance, any of the pile was valuable. Nothing was. As Janet said, if they really had wanted to play houses, two stools and an old carpet would have been just the thing, but from a selling point of view, they were just a dead loss.

"It was kind of her to remember," Cat said as he packed the heap into his cupboard.

"Except that now we'll have to remember to play houses with them," Janet said morosely. "As if we hadn't enough to do. Now, I will get this mirror down. I will!"

But the mirror refused to come down. Janet tried all three spells in both books, and it still stayed hanging in the air level with her head.

"You try, Cat," said Janet. "We can't leave it there."

Cat roused himself from gloomily staring at the ball of dough. It was still round. There was no sign that he had knelt on it, and that alarmed him. He knew it must be a very strong charm. But when Janet appealed to him, he sighed and reached up to pull the mirror down. His experience with Julia had taught him that a simple spell could usually be broken quite simply.

The mirror refused to descend an inch. But it slid about in the air. Cat was interested. He hung on to it with both hands, pushed off with his feet, and went traveling across the room in a most agreeable way.

"That looks fun," said Janet.

"It is," said Cat. "You try." They played with the mirror for some time after that. It could go as fast as they could push it, and it took the weight of both of them easily. Janet discovered that the best ride was to be had by standing on the chest of drawers and jumping. Then, provided you kept your feet up, you could swing across the room and land on Cat's bed. They were whirling together across the carpet, tangled up and laughing a good deal, when Roger knocked at the door and came in.

"I say, that's a good idea!" he said. "We've never thought of that. Can I have a go? And I met a peculiar cross-eyed man in the village, Gwendolen, and he gave me this letter for you."

Cat dropped off onto the carpet and took the letter. It was from Mr. Nostrum. Cat recognized the writing. He was so pleased that he said to Roger, "Have twenty goes if you want!" and rushed up to Janet with the letter. "Read it, quick! What does it say?"

Mr. Nostrum could get them out of their troubles. He might not be much of a necromancer, but he was surely able to turn Cat into a flea, if Janet asked him nicely. He would certainly have a charm that could make Cat look as if he could do magic. And though Mr. Nostrum was not rich, his brother William was.

He could lend Cat twenty pounds, if he thought he was helping Gwendolen.

Cat sat on the bed beside Janet and they read the letter, while Roger trundled about the room dangling from the mirror and chuckling placidly at what fun it was. Mr. Nostrum wrote: My dear and favorite pupil, I am here, domiciled at the White Hart Inn. It is most important-/ repeat, of the utmost importance-that you come to me here on Sat.u.r.day afternoon, bringing your brother to be briefed by me.

Your affectionate and proud teacher, Henry Nostrum At this, Janet looked nervous and mystified and moaned gently.

"I hope it's not bad news," Roger said, sailing past with his feet hooked up behind him.

"No, it's the best news we could have had!" Cat said. He dug Janet in the ribs to make her smile. She smiled dutifully, but he could not make her see that it was good news, even when he had a chance to explain.

"If he taught Gwendolen, he'll know I'm not her," she said. "And if he doesn't know, he won't understand why you want to be turned into a flea. It is an odd thing to go and ask, even in this world. And he'd want to know why I couldn't do it to you. Couldn't we tell him the truth?"

"No, because it's Gwendolen he's fond of," Cat explained. Something told him that Mr. Nostrum would be almost as little pleased as Chrestomanci to find that Gwendolen had departed for another world. "And he's got some kind of plans for her."

"Yes, this briefing," Janet said irritably. "He obviously thinks I know all about it. If you ask me, Cat, it's just one more d.a.m.ned thing!"

Nothing could convince Janet that salvation was at hand. Cat was quite sure it was. He went to sleep rejoicing, and woke up happy. He still felt happy, even when he trod on the lump of dough and it was cold and froglike under his foot. He covered it up with Magic for Beginners. Then he had to turn his attention to the mirror. It would keep drifting out into the middle of the room. Cat had to tether it to the bookcase with his Sunday bootlace in the end. He found Janet less happy than ever. Julia's latest idea was a mosquito. It met Janet as she came into breakfast, and it kept with her, whining in and biting, all through lessons, until Cat swatted it with his arithmetic book. What with this, and nasty looks from both Julia and Mary, and then having to meet Mr.

Nostrum, Janet became both peevish and miserable.

"It's all right for you," she said morbidly, as they tramped down the avenue on their way to the village that afternoon. "You've been brought up with all this magic and you're used to it. But I'm not. And what scares me is that it's forever. And it scares me even more that it isn't forever. Suppose Gwendolen gets tired of her new world and decides to move on again? When that happens, off we shall be dragged, a whole string of us doubles, and I'll be having to cope in her world, and you'll have all your troubles over again with a new one."

"Oh, I'm sure that won't happen," Cat said, rather startled at the possibility. "She's bound to come back soon."

"Oh, is she?" said Janet. They came through the gates, and again mothers s.n.a.t.c.hed children out of their sight, and the village green emptied as they reached it. "I wish I was back at home!" Janet wailed, almost in tears at the way everyone ran away.

13.

They were ushered into a private parlor in the White Hart. Mr. Henry Nostrum rolled pompously to meet them.

"My dear young friends!" He put his hands on Janet's shoulders and kissed her. Janet started backwards, knocking her hat over one ear. Cat was a little shaken. He had forgotten Mr. Nostrum's seedy, shabby look, and the weird effect of his wandering left eye. "Sit down, sit down!" said Mr. Nostrum heartily.

"Have some ginger beer."

They sat down. They sipped ginger beer, which neither of them liked. "What did you want me for, as well as Gwendolen?" Cat asked.

"Because," said Mr. Nostrum, "to come straight to the point and not to beat about the bush, we find, as we rather feared we would, that we are quite unable to make use of those three signatures which you were kind enough to donate to me for services rendered in the tuition line. The Person Who Inhabits That Castle Yonder, whose name I disdain to say, signs his name under unbreakable protections. You may call it prudent of him. But I fear it necessitates our using Plan Two. Which was why, my dear Cat, we were so glad to arrange for you to live at the Castle."

"What is Plan Two?" said Janet.

Mr. Nostrum's odd eye slipped sideways across Janet's face. He did not seem to realize she was not Gwendolen. Perhaps his wandering eye did not see very well. "Plan Two is just as I described it to you, my dear Gwendolen," he said. "We have not changed it one whit."

Janet had to try another way to find out what he was talking about. She was getting quite good at it. "I want you to describe it to Cat, though," she said. "He doesn't know about it, and he may need to because--because most unfortunately they've taken my witchcraft away."

Mr. Nostrum wagged a playful finger at her. "Yes, naughty girl. I've been hearing things about you in the village. A sad thing to lose, but let us hope it will only be temporary. Now-as to explaining to Young Chant-how shall I best go about it?" He thought, smoothing his frizzy wings of hair, as his habit was.Somehow, the way he did it showed Cat that whatever Mr. Nostrum was going to tell him, it would not be quite the truth. It was in the movement of Mr. Nostrum's hands, and in the very sit of his silver watch-chain across his shabby, rounded waistcoat.

"Well, Young Chant," said Mr. Nostrum, "this is the matter in a nutsh.e.l.l. There is a group, a clique, a collection of people, headed by the Master of the Castle, who are behaving very selfishly in connection with witchcraft. They are keeping all the best things to themselves, which of course makes them very dangerous-a threat to all witches, and a looming disaster to ordinary people. For instance, take dragons' blood. You know that it is banned. These people, with That Person at their head, had it banned, and yet-mark this well, Young Chant- they use it daily themselves. And-here is my point-they keep tight control of the ways to get to the worlds where dragons' blood comes from. An ordinary necromancer like myself can only get it at great risk and expense, and our exotic suppliers have to endanger themselves to get it for us. And the same goes for almost any product from another world.

"Now, I ask you, Young Chant, is this fair? No. And I'll tell you why not, young Eric. It is not fair that the ways to other worlds should be in the hands of a few. That is the crux of the matter: the ways to other worlds. We want them opened up, made free to everyone. And that is where you come in, Young Chant.

The best and easiest way, the broadest Gateway to Elsewhere, if I may put it like that, is a certain enclosed garden in the grounds of this said Castle. I expect you have been forbidden to enter it-"

"Yes," said Cat. "We have been."

"And consider how unfair!" said Mr. Nostrum. "The Master of That Place uses it every day and travels where he pleases. So what I want you to do, Young Chant, and this is all Plan Two amounts to, is to go into that garden at two-thirty precisely on Sunday afternoon. Can you promise me to do that?"

"What good would that do?" asked Cat.

"It would break the seal of enchantment these dastardly persons have set on the Gateways to Elsewhere," Mr. Nostrum said.

"I've never quite understood," Janet said, with a very convincing wrinkle in her forehead, "how Cat could break the seals just by going into the garden."

Mr. Nostrum looked a little irritated. "By being an ordinary innocent lad, of course. My dear Gwendolen, I have stressed to you over and over again the importance of having an innocent lad at the center of Plan Two. You must understand."

"Oh, I do, I do," Janet said hastily. "And has it to be this Sunday at two-thirty?"

"As ever is," said Mr. Nostrum, smiling again. "It's a good strong time. Will you do that for us, Young Chant? Will you, by this simple act, set your sister and people like her free-free to do as they need in the practice of magic?"

"I'll get into trouble if I'm caught," said Cat.

"A bit of boyish cunning will see you through. Then, never fear, we'll take care of you afterwards," Mr.

Nostrum persuaded.
