"I'm sure you wouldn't hurt a fly," said the aunt absently. "Goodbye. Be good children."

And on this they got away quickly.

"Why," said Gerald, when they were outside the little court, "your aunt's as mad as a hatter. Fancy not caring what becomes of you, and fancy believing that rot about the motor lady!"

"I knew she'd believe it when I wrote it," said Mabel modestly. "She's not mad, only she's always reading novelettes. I read the books in the big library. Oh, it's such a jolly room – such a queer smell, like boots, and old leather books sort of powdery at the edges. I'll take you there some day. Now your consciences are all right about my aunt, I'll tell you my great idea. Let's get down to the Temple of Flora. I'm glad you got aunt's permission for the grounds. It would be so awkward for you to have to be always dodging behind bushes when one of the gardeners came along."

"Yes," said Gerald modestly, "I thought of that."

The day was as bright as yesterday had been, and from the white marble temple the Italian-looking landscape looked more than ever like a steel engraving coloured by hand, or an oleographic imitation of one of Turner's pictures.

When the three children were comfortably settled on the steps that led up to the white statue, the voice of the fourth child said sadly: "I'm not ungrateful, but I'm rather hungry. And you can't be always taking things for me through your larder window. If you like, I'll go back and live in the castle. It's supposed to be haunted. I suppose I could haunt it as well as any one else. I am a sort of ghost now, you know. I will if you like."

"Oh no," said Kathleen kindly; "you must stay with us."

"But about food. I'm not ungrateful, really I'm not, but breakfast is breakfast, and bread's only bread."

"If you could get the ring off, you could go back."

"Yes," said Mabel's voice, "but you see, I can't. I tried again last night in bed, and again this morning. And it's like stealing, taking things out of your larder – even if it's only bread."

"Yes, it is," said Gerald, who had carried out this bold enterprise.

"Well, now, what we must do is to earn some money."

Jimmy remarked that this was all very well. But Gerald and Kathleen listened attentively.

"What I mean to say," the voice went on, "I'm really sure is all for the best, me being invisible. We shall have adventures – you see if we don't."

"'Adventures,' said the bold buccaneer, 'are not always profitable.'" It was Gerald who murmured this.

"This one will be, anyhow, you see. Only you mustn't all go. Look here, if Jerry could make himself look common – "

"That ought to be easy," said Jimmy. And Kathleen told him not to be so jolly disagreeable.

"I'm not," said Jimmy, "only – "

"Only he has an inside feeling that this Mabel of yours is going to get us into trouble," put in Gerald. "Like La Belle Dame Sans Merci, and he does not want to be found in future ages alone and palely loitering in the middle of sedge and things."

"I won't get you into trouble, indeed I won't," said the voice. "Why, we're a band of brothers for life, after the way you stood by me yesterday. What I mean is – Gerald can go to the fair and do conjuring."

"He doesn't know any," said Kathleen.

"I should do it really," said Mabel, "but Jerry could look like doing it. Move things without touching them and all that. But it wouldn't do for all three of you to go. The more there are of children the younger they look, I think, and the more people wonder what they're doing all alone by themselves."

"The accomplished conjurer deemed these the words of wisdom," said Gerald; and answered the dismal "Well, but what about us?" of his brother and sister by suggesting that they should mingle unsuspected with the crowd. "But don't let on that you know me," he said; "and try to look as if you belonged to some of the grown-ups at the fair. If you don't, as likely as not you'll have the kind policemen taking the little lost children by the hand and leading them home to their stricken relations – French governess, I mean."

"Let's go now," said the voice that they never could get quite used to hearing, coming out of different parts of the air as Mabel moved from one place to another. So they went.

The fair was held on a waste bit of land, about half a mile from the castle gates. When they got near enough to hear the steam-organ of the merry-go-round, Gerald suggested that as he had ninepence he should go ahead and get something to eat, the amount spent to be paid back out of any money they might make by conjuring. The others waited in the shadows of a deep-banked lane, and he came back, quite soon, though long after they had begun to say what a long time he had been gone. He brought some Barcelona nuts, red-streaked apples, small sweet yellow pears, pale pasty gingerbread, a whole quarter of a pound of peppermint bull's-eyes, and two bottles of gingerbeer.

"It's what they call an investment," he said, when Kathleen said something about extravagance. "We shall all need special nourishing to keep our strength up, especially the bold conjurer."

They ate and drank. It was a very beautiful meal, and the far-off music of the steam-organ added the last touch of festivity to the scene. The boys were never tired of seeing Mabel eat, or rather of seeing the strange, magic-looking vanishment of food which was all that showed of Mabel's eating. They were entranced by the spectacle, and pressed on her more than her just share of the feast, just for the pleasure of seeing it disappear.

"My aunt!" said Gerald, again and again; "that ought to knock 'em!"

It did.

Jimmy and Kathleen had the start of the others, and when they got to the fair they mingled with the crowd, and were as unsuspected as possible.

They stood near a large lady who was watching the cocoanut shies, and presently saw a strange figure with its hands in its pockets strolling across the trampled yellowy grass among the bits of drifting paper and the sticks and straws that always litter the ground of an English fair. It was Gerald, but at first they hardly knew him. He had taken off his tie, and round his head, arranged like a turban, was the crimson school-scarf that had supported his white flannels. The tie, one supposed, had taken on the duties of the handkerchief. And his face and hands were a bright black, like very nicely polished stoves!

Every one turned to look at him.

"He's just like a nigger!" whispered Jimmy. "I don't suppose it'll ever come off, do you?"

They followed him at a distance, and when he went close to the door of a small tent, against whose door-post a long-faced melancholy woman was lounging, they stopped and tried to look as though they belonged to a farmer who strove to send up a number by banging with a big mallet on a wooden block.

Gerald went up to the woman.

"Taken much?" he asked, and was told, but not harshly, to go away with his impudence.

"I'm in business myself," said Gerald, "I'm a conjurer, from India."

"Not you!" said the woman; "you ain't no nigger. Why, the backs of yer ears is all white."

"Are they?" said Gerald. "How clever of you to see that!" He rubbed them with his hands. "That better?"

"That's all right. What's your little game?"

"Conjuring, really and truly," said Gerald. "There's smaller boys than me put on to it in India. Look here, I owe you one for telling me about my ears. If you like to run the show for me I'll go shares. Let me have your tent to perform in, and you do the patter at the door."

"Lor' love you! I can't do no patter. And you're getting at me. Let's see you do a bit of conjuring, since you're so clever an' all."

"Right you are," said Gerald firmly. "You see this apple? Well, I'll make it move slowly through the air, and then when I say 'Go!' it'll vanish."

"Yes – into your mouth! Get away with your nonsense."

"You're too clever to be so unbelieving," said Gerald. "Look here!"

He held out one of the little apples, and the woman saw it move slowly and unsupported along the air.

"Now —go!" cried Gerald, to the apple, and it went. "How's that?" he asked, in tones of triumph.

The woman was glowing with excitement, and her eyes shone. "The best I ever see!" she whispered. "I'm on, mate, if you know any more tricks like that."

"Heaps," said Gerald confidently; "hold out your hand." The woman held it out; and from nowhere, as it seemed, the apple appeared and was laid on her hand. The apple was rather damp.

She looked at it a moment, and then whispered: "Come on! there's to be no one in it but just us two. But not in the tent. You take a pitch here, 'longside the tent. It's worth twice the money in the open air."

"But people won't pay if they can see it all for nothing."

"Not for the first turn, but they will after – you see. And you'll have to do the patter."

"Will you lend me your shawl?" Gerald asked. She unpinned it – it was a red and black plaid – and he spread it on the ground as he had seen Indian conjurers do, and seated himself cross-legged behind it.

"I mustn't have any one behind me, that's all," he said; and the woman hastily screened off a little enclosure for him by hanging old sacks to two of the guy-ropes of the tent. "Now I'm ready," he said. The woman got a drum from the inside of the tent and beat it. Quite soon a little crowd had collected.

"Ladies and gentlemen," said Gerald, "I come from India, and I can do a conjuring entertainment the like of which you've never seen. When I see two shillings on the shawl I'll begin."

"I dare say you will!" said a bystander; and there were several short, disagreeable laughs.

"Of course," said Gerald, "if you can't afford two shillings between you" – there were about thirty people in the crowd by now – "I say no more."

Two or three pennies fell on the shawl, then a few more, then the fall of copper ceased.

"Ninepence," said Gerald. "Well, I've got a generous nature. You'll get such a nine-pennyworth as you've never had before. I don't wish to deceive you – I have an accomplice, but my accomplice is invisible."

The crowd snorted.

"By the aid of that accomplice," Gerald went on, "I will read any letter that any of you may have in your pocket. If one of you will just step over the rope and stand beside me, my invisible accomplice will read that letter over his shoulder."

A man stepped forward, a ruddy-faced, horsy-looking person. He pulled a letter from his pocket and stood plain in the sight of all, in a place where every one saw that no one could see over his shoulder.

"Now!" said Gerald. There was a moment's pause. Then from quite the other side of the enclosure came a faint, far-away, sing-song voice. It said: —

"'Sir, – Yours of the fifteenth duly to hand. With regard to the mortgage on your land, we regret our inability – '"

"Stow it!" cried the man, turning threateningly on Gerald.

He stepped out of the enclosure explaining that there was nothing of that sort in his letter; but nobody believed him, and a buzz of interested chatter began in the crowd, ceasing abruptly when Gerald began to speak.

"Now," said he, laying the nine pennies down on the shawl, "you keep your eyes on those pennies, and one by one you'll see them disappear."

And of course they did. Then one by one they were laid down again by the invisible hand of Mabel. The crowd clapped loudly. "Brayvo!" "That's something like!" "Show us another!" cried the people in the front rank. And those behind pushed forward.

"Now," said Gerald, "you've seen what I can do, but I don't do any more till I see five shillings on this carpet."

And in two minutes seven-and-threepence lay there and Gerald did a little more conjuring.

When the people in front didn't want to give any more money, Gerald asked them to stand back and let the others have a look in. I wish I had time to tell you of all the tricks he did – the grass round his enclosure was absolutely trampled off by the feet of the people who thronged to look at him. There is really hardly any limit to the wonders you can do if you have an invisible accomplice. All sorts of things were made to move about, apparently by themselves, and even to vanish – into the folds of Mabel's clothing. The woman stood by, looking more and more pleasant as she saw the money come tumbling in, and beating her shabby drum every time Gerald stopped conjuring.

The news of the conjurer had spread all over the fair. The crowd was frantic with admiration. The man who ran the cocoanut shies begged Gerald to throw in his lot with him; the owner of the rifle gallery offered him free board and lodging and go shares; and a brisk, broad lady, in stiff black silk and a violet bonnet, tried to engage him for the forthcoming Bazaar for Reformed Bandsmen.

And all this time the others mingled with the crowd – quite unobserved, for who could have eyes for any one but Gerald? It was getting quite late, long past tea-time, and Gerald, who was getting very tired indeed, and was quite satisfied with his share of the money, was racking his brains for a way to get out of it.

"How are we to hook it?" he murmured, as Mabel made his cap disappear from his head by the simple process of taking it off and putting it in her pocket. "They'll never let us get away. I didn't think of that before."

"Let me think!" whispered Mabel; and next moment she said, close to his ear: "Divide the money, and give her something for the shawl. Put the money on it and say…" She told him what to say.

Gerald's pitch was in the shade of the tent; otherwise, of course, every one would have seen the shadow of the invisible Mabel as she moved about making things vanish.

Gerald told the woman to divide the money, which she did honestly enough.

"Now," he said, while the impatient crowd pressed closer and closer. "I'll give you five bob for your shawl."

"Seven-and-six," said the woman mechanically.

"Righto!" said Gerald, putting his heavy share of the money in his trouser pocket.

"This shawl will now disappear," he said, picking it up. He handed it to Mabel, who put it on; and, of course, it disappeared. A roar of applause went up from the audience.

"Now," he said, "I come to the last trick of all. I shall take three steps backward and vanish." He took three steps backward, Mabel wrapped the invisible shawl round him, and – he did not vanish. The shawl, being invisible, did not conceal him in the least.

"Yah!" cried a boy's voice in the crowd. "Look at 'im! 'E knows 'e can't do it."

"I wish I could put you in my pocket," said Mabel. The crowd was crowding closer. At any moment they might touch Mabel, and then anything might happen – simply anything. Gerald took hold of his hair with both hands, as his way was when he was anxious or discouraged. Mabel, in invisibility, wrung her hands, as people are said to do in books; that is, she clasped them and squeezed very tight.

"Oh!" she whispered suddenly, "it's loose. I can get it off."

"Not – "

"Yes – the ring."

"Come on, young master. Give us summat for our money," a farm labourer shouted.

"I will," said Gerald. "This time I really will vanish. Slip round into the tent," he whispered to Mabel. "Push the ring under the canvas. Then slip out at the back and join the others. When I see you with them I'll disappear. Go slow, and I'll catch you up."

"It's me," said a pale and obvious Mabel in the ear of Kathleen. "He's got the ring; come on, before the crowd begins to scatter."

As they went out of the gate they heard a roar of surprise and annoyance rise from the crowd, and knew that this time Gerald really had disappeared.

They had gone a mile before they heard footsteps on the road, and looked back. No one was to be seen.

Next moment Gerald's voice spoke out of clear, empty-looking space.

"Halloa!" it said gloomily.

"How horrid!" cried Mabel; "you did make me jump! Take the ring off. It makes me feel quite creepy, you being nothing but a voice."

"So did you us," said Jimmy.

"Don't take it off yet," said Kathleen, who was really rather thoughtful for her age, "because you're still black, I suppose, and you might be recognised, and eloped with by gipsies, so that you should go on doing conjuring for ever and ever."

"I should take it off," said Jimmy; "it's no use going about invisible, and people seeing us with Mabel and saying we've eloped with her."

"Yes," said Mabel impatiently, "that would be simply silly. And, besides, I want my ring."

"It's not yours any more than ours, anyhow," said Jimmy.

"Yes, it is," said Mabel.

"Oh, stow it!" said the weary voice of Gerald beside her. "What's the use of jawing?"

"I want the ring," said Mabel, rather mulishly.

"Want" – the words came out of the still evening air – "want must be your master. You can't have the ring. I can't get it off!"
