Darrell listened to this in surprise. "But you can't love a person and hate them at the same time," she said, at last.

"You can," said Ruth, fiercely. "You can, Darrell. I love Connie because she's my twin-and hate her because-because-oh, I can't tell you."

Darrell looked for a long time at Ruth's bent head, and saw the tears rolling off her cheeks. "I think I know why you hate Connie," she said at last. "Isn't it because she's so domineering-always answering for you, doing things for you that you'd rather do yourself-pushing herself in front of you-as if she was at least two years older?"

"Yes," said Ruth, rubbing her wet cheeks. "I never get a chance to say what I think. Connie always gets in first. Of course, I know she must have a better brain than I have, but..."

"She hasn't," said Darrell, at once. "Actually she ought to be in the lower fourth, not in the upper. I heard Miss Williams say so. They only put her with you in the upper cla.s.s because you were twins, and your mother said you wouldn't like to be separated. Connie only keeps up with the form because you help her so much!"

There was a silence. Darrell thought about everything all over again. How very queer this was! Then a question arose in her mind and she asked Ruth at once.

"Ruth-why did you suddenly begin to be so beastly to Connie? You never were before, so far as I noticed. It all seemed quite sudden."

"I can't tell you," said Ruth. "But oh-I'm so miserable about it."

"Well, if you won't tell me, I shall go and ask Connie," said Darrell, getting up. "Something's gone awfully wrong, Ruth, and I don't know if I can put it right, but I'm going to have a jolly good try."

"Don't go to Connie," begged Ruth. "I don't want you to tell her it was me that was so beastly all the time. And oh, Darrell, I was so sorry for Connie, too, when I saw how upset she was at losing her things. It's dreadful to hate somebody and make them unhappy, and then to know you love them, and try to comfort them!"

"I suppose that's why you kept giving Connie your own things," said Darrell, sitting down on a tub. "Queer business, this! First you hate your twin and do something to upset her, like spoiling the riding-whip she loved-and then you love her and are sorry-and come to give her your own riding-whip! I could see you were upset when she didn't take it."

"Darrell-I will tell you why I hated Connie so much lately," said Ruth, suddenly, wiping her eyes with her hands. "I feel I've got to tell someone. Well-it was something awful."

"Whatever was it?" said Darrell, curiously.

"You see-Connie adores me, and likes to protect me and do everything for me," began Ruth. "And so far we have always been in the same cla.s.s together. But Connie was afraid she would fail in School Cert, and felt sure I would pa.s.s."

"So you would," said Darrell. "And Connie would certainly fail! "

"Well-Connie thought that if she failed and I pa.s.sed, I'd go up into the lower fifth next term, and she would have to stay down in the Upper Fourth and take the exam again another term," went on Ruth. "And that would mean she wouldn't be with me any more. So she asked me to do a bad paper, so that I would fail, too-and then we could still be together!"

Darrell was so astonished at this extraordinary statement that she couldn't say a single word. At last she found her tongue.

"Ruth! how wicked! To make you fail and feel humiliated when you could so easily pa.s.s! She can't love you."

"Oh, but she does-too much!" said Ruth. "Anyway, I said I would do a bad paper-somehow I just can't help doing what Connie wants, even if it's something horrid like that-so I did do a bad paper-and then afterwards I hated Connie so much for making me do it that I did all these horrible things to her!"

Poor Ruth put her face in her hands and began to sob. Barrel! went and sat on the sacks beside her and put her strong comforting arm round Ruth's shoulders.

"I see," she said. "It's all very peculiar and extraordinary, but somehow quite understandable. It's because you're twins, I expect. Connie should have been your elder sister, then it wouldn't have mattered! You could have loved each other like ordinary sisters do, and you'd have been in different forms, and things would have been all right. Cheer up, Ruth. It's all been frightening and horrible to you, but honestly I can see quite well how it all happened."

Ruth looked up, comforted by Barren's simple explanation. She pushed her hair back and sniffed.

"Darrell, please, please don't tell Connie I did all those things," she said. "I'm awfully sorry now that I did. She wouldn't understand, and she'd be awfully upset and unhappy. I couldn't bear that."

"Yes-but you can't go on like this-being bossed by Connie, and being just an echo for her," said Darrell, sensibly. "I don't see any way of stopping it except for us to tell her. I'll come with you if you like."

But Ruth began to sob so much when Darrell suggested this that Darrell had to give up the idea. A distant bell sounded and she got up. "You'd better go and bathe your eyes," she said kindly. "I'll try and think of some way to put things right without telling Connie-but it's going to be difficult!"

Ruth went off, sniffing, but much comforted. Darrell rubbed her nose hard, as she often did when she was puzzled. "There's only one thing to do!" she said. "And that's to tell Miss Williams. Something's got to be done! "

So that evening, after supper, Miss Williams was astonished to find Darrell at her door, asking for an interview. She wondered if Darrell had come to beg to have her position as head-girl restored to her. But it wasn't that.

Darrell poured out the strange story of the twins. Miss Williams listened in the greatest amazement The things that could go on in a school, that n.o.body knew about, even though the girls concerned were under her nose all day long!

"So, you see, Miss Williams," finished Darrell, "if Ruth can't bear Connie to be told, everything is as bad as before! They'll both fail the exam, they'll both stay down in the Upper Fourth, instead of going up next term, and poor Ruth will go on being domineered over, and will hate and love Connie at the same time. It must be horrible."

"Very horrible," thought Miss Williams, horrified. "And very dangerous. Things like this often lead to something very serious later on." She did not say this to Darrell, who sat earnestly watching her, waiting for some advice.

"Darrell, I think it was very clever of you to find this out," said Miss Williams, at last. "And you have acted very wisely all through. I do really feel very pleased with you."

Darrell went red and looked pleased. "Can you think how to put things right?" she asked. "Oh, Miss Williams, wasn't it a pity that Ruth did a bad exam paper! If she hadn't, things would have got right of themselves-the twins would have been in different forms."

"Darrell," said Miss Williams after a pause, "what I am going to say now is between you and me. I glanced at all the exam papers before sending them up-and Ruth didn't do quite as bad a one as she thought! In fact, I feel pretty certain she will sc.r.a.pe through."

"Oh good!" said Darrell, delighted. "I never thought of that. So they'll be in different forms next term after all, then!"

"I think so," said Miss Williams. "That will give Ruth a chance to stand on her own feet and develop a personality of her own, instead of being Connie's shadow-and Connie will have to stop domineering over her-it will all disappear naturally and gradually, which is the best thing that could happen, in this curious case."

"Won't Connie know anything then?" asked Darrell. "Won't she have to be told?"

"That will be Ruth's business, and no concern of anyone else's," said Miss Williams. "Some day, when the right time comes, she may choose to confess to Connie-and perhaps they will even laugh at it all. Keep an eye on Ruth for me, will you, Darrell, for the rest of the term? You're in her confidence now and I shall trust you to see that nothing else goes wrong between the twins."

"Oh, I will," said Darrell, pleased to be asked this. "I'd love to. I like Ruth."

"And Darrell-I shall make you head-girl again in two days' time," said Miss Williams. "And this time I shall be very, very proud of you!"

"Ping!"

Everyone was delighted when Miss Williams announced in her quiet voice, two days later, that Darrell was once more to be head-girl of the form. "Thank you for taking on the position temporarily," she said to Sally. "But I am now convinced that Darrell deserves to be promoted again."

"Why, Darrell? Why has Miss Williams put you back as head this week?" asked Belinda and the others, after cla.s.s. But Darrell didn't tell them, of course. Miss Williams hadn't actually said that it was because of her trying to put right the affair of the twins-but she knew that it was. She had really acted like a responsible head-girl then.

No more spiteful things were done to Connie, and gradually the Connie Affair, as it was called, was forgotten. Ruth seemed to forget her dislike and resentment, and was very sweet to Connie. "Next term," thought Darrell, "things will be quite all right-they'll be in different forms, and Ruth can go ahead with her good brains, and Connie can work at her own pace and keep her hands off Ruth."

The term was slipping away fast now. Alicia was better, and fortunately no one else had caught measles from her. Most of the Upper Fourth had already had them, which was fortunate. Alicia groaned because she felt sure she had failed-and would have to take the School Certificate all over again. She was to come back to school a week before Breaking-Up. The girls were very pleased. They had all missed Alicia's quickness and sense of fun. Gwendoline was perhaps the only one who didn't want her back.

Poor Gwen-she had already lost some of her fat, through having to play so much tennis and go for so many walks, and swim-or try to-each day! But she certainly looked healthier, and her spots were rapidly going.

Clarissa amazed the cla.s.s one day by coming back from a visit to the dentist and the occulist looking completely different! "I haven't got to wear gla.s.ses any more!" she announced. "And that awful wire's been taken from my front teeth. Do you recognize me, girls?"

"Hardly!" said Darrell, and Belinda got out her pencil to make a sketch of this different and most attractive Clarissa!

She stood laughing in front of them-her deep green eyes flashing round, and her white teeth no longer spoilt by an ugly wire. Her wavy auburn hair suited her eyes, and she looked unusual and somehow distinguished.

"You'll be a beauty one day, Clarissa," said Belinda, her artist's eye seeing Clarissa at twenty-one, lovely and unusual in her colouring. "Well, well-talk about an ugly duckling turning into a swan!"

Clarissa was now fast friends with Bill, much to the girls' amus.e.m.e.nt. n.o.body had ever thought that the boyish Bill, who seemed only to care for her horse Thunder, and for Miss Peters (but a good way behind Thunder!) would make a friend in her form. But she had, and the two chattered continually together, always about horses, and rode whenever they could. Gwendoline didn't care. Since she had seen Clarissa going off at half-term with the dowdy-looking elderly woman in the old Austin car, she had taken no further interest in her.

Gwendoline wanted a grand friend, not somebody ordinary, whose people didn't even dean their old car when they came at half-term! So Gwen was once more alone, with no one to talk or giggle with, no one to call her friend.

"We ought to do something to celebrate Alicia coming back?" said Belinda. "She's coming tomorrow."

"Yes! Let's do something," said Darrell, at once.

"Something mad and bad," said Betty, who was in the courtyard with the others.

"A trick!" said Irene. "We haven't played a trick for two whole terms. Think of it! What are we coming to? We must be getting old and staid."

"Yes, let's play a trick," said Sally. "After all, the exams are over, and we worked jolly hard-we deserve a really good laugh!"

"What trick shall we play?" asked Mavis. "Betty, didn't you bring anything back this term? Last term you brought back that awful spider that could dangle from the ceiling like a real one-but we never got a chance of using it. Gosh, I'd like to have seen Mam'zelle's face if we had managed to let it down over her desk!"

Everyone giggled. "I didn't bring it back with me this term," said Betty, regretfully. "I stayed with Alicia in the hols and one of her brothers bagged it. But I tell you what I have got!"

"What?" asked everyone, getting thrilled.

"I haven't tried them yet," said Betty. "They're awfully queer things. They're little grey pellets, quite flat. One side is sticky, and you stick it to the ceiling."

"What happens?" asked Irene.

"You have to dab each pellet with some kind of liquid," said Betty, trying to remember. "At least, I think that's right-and then, according to the instructions, a queer bubble detaches itself slowly from the pellet, floats downwards, and suddenly pops-and makes a pinging sound."

Everyone listened in delight. "Betty! It's too marvellous for words!" said Irene, thrilled. "Let's play the trick tomorrow, to celebrate Alicia's coming back. We'll Betty stuck some pellets to the have to get the step-ladder to put some of the pellets on the ceiling. Let's do it when Mam'zelle takes us. She's always fun to play tricks on."

So, with much secrecy, the step-ladder was hidden in the cupboard outside the Upper Fourth cla.s.sroom, and just before morning school, three fiat grey pellets were quickly fixed to the ceiling, where, quite miraculously, so it seemed to the girls, they stuck very tightly indeed, and could hardly be seen at all.

Betty brushed each one over quickly with the liquid from a small bottle sent with the pellets. Then the ladder was bundled into the cupboard again, just as Mam'zelle's high heels were heard tip-tapping down the corridor. Daphne flew to hold the door open, and the others stood ready in their places.

"Merci, Daphne," said Mam'zelle, briskly. "Ah, Alicia-it is very, very good to see you back. You have had a bad time with your measle?"

"Well, actually I didn't mind my measle very much, after the first day," said Alicia. with a grin. She was looking very well now.

"It is good that no one got the measle from you," said Mam'zelle, sitting down at her desk.

"I had a measle last year," said Irene, and this was the signal for everyone to talk about when they had a measle, too. Mam'zelle had to bring the talk to an end, because it showed signs of getting very boisterous.

"We will have no more measly talk," she said, firmly, and wondered why the girls laughed so much at this.

They took quick, surrept.i.tious glances at the ceiling every now and again, longing to see the new trick at work. Alicia had heard all about it, of course, and was thrilled with their novel way of celebrating her return. She had suggested that everyone should pretend they could not see the bubbles, or hear the "ping" when they exploded.

"Mam'zelle will think she's gone crackers," she said. "I know I should if I saw bubbles that pinged round me when n.o.body else did!"

"Today I go through the questions that you answered on the exam paper," said Mam'zelle, smiling round. "You will tell me what you put and I will say if it was good or no."

"Oh no, Mam'zelle," protested Alicia. "We had to do the exam-let's forget it now it's over. Anyway, I did such a frightful paper, I've failed, I know. I can't bear to think of the exam questions now."

Irene nudged Belinda. One of the grey pellets was beginning its performance. A small grey bubble was beginning to form up on the ceiling. It grew a little bigger, became heavy enough to detach itself, and floated gently down into the air. All three pellets had been placed just above the big desk belonging to Miss Williams., where Mam'zelle was now sitting.

With bated breath the girls watched the bubble slowly descend. It looked as if it was about to fall on Mam'zelle's head, decided not to, and skirted round her hair, near her left ear. When it got there, it burst suddenly, and a curious sharp, very metallic "ping" sounded.

Mam'zelle almost jumped out of her skin. "Tiens!" she said "Qu'est ce que c'est que go! What was that!"

"What was what, Mam'zdle?" asked Sally, innocently.

"A ping-comme qal?" said Mam'zelle, and pinged again. "Ping! Did you not hear a ping, Sally ? "

"A ping? What exactly do you mean, Mam'zelle?" asked Sally, putting on a puzzled look that made Darrell want to cry with laughter. "You don't mean a pong, do you?"

"Perhaps she means a ping-pong," suggested Irene, and began to giggle. So did Mavis. Darrell frowned at them.

"I sit here, and suddenly in my ear there comes a ping!" said Mam'zelle. "I feel it on my ear."

"Oh, I thought you meant you heard it," said Sally.

"I hear it and I feel it," said Mam'zelle. "Que c'est drole, go! How queer!"

Another bubble was now descending. The girls, trying not to appear as if they were watching it, waited for it to descend near Mam'zelle. It floated down and exploded behind her head. "Ping!" It was a most extraordinary little sound, small but very sharp and dear.

Mam'zelle leapt to her feet wildly. She turned and looked behind her. "There it comes again!" she cried. "It was on my neck-and ping! it went. What can this be?"

"I expect it's just noises in your ears, Mam'zelle," said Darrell, comfortingly. This made Irene give one of her terrific snorts, and Daphne and Mavis began to laugh helplessly.

"Do you not hear this 'ping', Darrell?" said Mam'zelle, beginning to look scared. "I am..."

"Ping!" Another bubble popped with a ping, and Mam'zelle stood with her mouth open in amazement. What was this pinging? And why could not the girls hear it? Aha-was it a trick?

"Is this a trick?" she began. "A bad, wicked trick on your poor old Mam'zelle again? I have not..."

Ping! A little bubble landed fairly and squarely on Mam'zelle's bun of hair on the top of her head and pinged valiantly. Mam'zelle shrieked.

"What is it?" she cried. "Stop laughing, girls! Tell me what it is, this ping."

She saw Irene looking up at the ceiling and she looked, too. But at that moment no bubble was descending, and she saw nothing. Then a bubble which had actually got almost to the floor without popping, pinged just by her foot. Mam'zelle jumped as if she had been shot. She leapt up again and made for the door.

"C'est unbelievable!" she cried. "It is unbelievable. I go to fetch help!"

Last Week of Term.

By this time, of course, the girls were almost helpless with laughter. Tears were pouring down Darrell's cheeks and Sally was holding her sides, aching with laughter. Irene appeared to be choking and Alicia and Betty were holding on to each other helplessly.

Mam'zelle rushed to Miss Williams. She was taking a cla.s.s in the second form, and was amazed at Mam'zelle's sudden entrance.

"Miss Williams! I beg you to come with me to your cla.s.sroom," Mam'zelle besought the astonished Miss Williams. "It goes "ping!" right in my ears-yes, and down by my foot."

Miss Williams looked astounded. Was Mam'zelle of! her head? What was all this ping and pong business? The second form began to giggle.
