This threat was enough to cause Johnny and Caspar a little energetic work. By the time the Ogre’s heavy feet were heard on the stairs, Caspar had piled books, papers and records in a sort of heap by the wall, and Johnny had pushed most of the construction kits under his bed and the cupboard, so that, apart from the chemistry set, the floor was almost clear.

  The Ogre stood in the doorway, with his hands in his pockets and his pipe in his mouth and looked round the room with distaste. “You do like to live in squalor, don’t you?” he said. “I suppose all those toffee bars are an essential part of your diet? OK. I’ll report a clear floor. How are you getting on with that chemistry set?”

  “I like it,” Johnny said, with a polite smile. “But I’ve been too busy clearing up to use it yet.”

  The Ogre’s heavy eyebrows went up and he looked rather pointedly round the room. “I’ll leave you to it, then,” he said. A thought struck him. “I suppose I ought in fairness to make a surprise inspection over the way,” he said. They watched him turn and walk across the landing. They saw him open the door to Malcolm’s and Douglas’s room. They waited hopefully. It would be wonderful if, for once, it was those two who got into trouble.

  Nothing happened, however, except for a surprisingly strong stench, which swept across the landing and made Caspar cough. Malcolm’s voice followed it. “This chemistry set is positively brilliant, Father! Look at this.”

  “Having fun, are you?” said the Ogre, and he shut the door rather hastily and went downstairs.

  “Pooh!” said Caspar.

  “I just like that!” said Johnny. “If it had been us making a smell like that, we wouldn’t half have got it! All right then. Watch me after supper. I’ll make the worst stink you ever smelt, and if he says anything, I’ll say, what about Malcolm?”

  Johnny was as good as his word. After supper, he set to work in the middle of the carpet, mixing all the strongest and likeliest-looking things from the various tubes and phials and heating them with the spirit lamp to see what happened. When he found a good smell, he poured it carefully into a toothmug and mixed another. The savour of the room went through rotten cabbage, elderly egg, mouldy melon, gasworks and bad breath; blue smoke hung about in it. Caspar, who was lying on his bed doing history homework, coughed considerably, but he bore it in a good cause.

  When Gwinny came in instead of going to bed, she was exquisitely disgusted. She sat beside Johnny in her pink nightdress, wriggling her bare toes and pretending to smoke one of the Ogre’s pipes that she had stolen. “Eeugh!” she said, and peered at Johnny’s flushed face through the gathering smoke. “We look like a witches’ convent. Caspar looks like a devil looming through the smoke.”

  “Coven,” said Caspar. “Devil yourself.”

  Giggling, Gwinny stuck her spiky hair out round her head and carefully tapped some of the ash out of the pipe into the toothmug. The mixture fizzed a little. “Do you think it’ll explode now?” she asked hopefully.

  “Shouldn’t think so,” said Johnny. “Move, or you’ll get burnt.”

  “Is it smelly enough?” asked Gwinny.

  “I still haven’t found the one Malcolm got,” admitted Johnny.

  “Try a dead fish or so. That should do it,” Caspar suggested. Gwinny squealed with laughter.

  “Gwinny!” boomed the voice of the Ogre. “Are you in bed?”

  Gwinny dropped the pipe, jumped up and fled. In her hurry, she knocked the toothmug flying and Johnny was too late to save it. Half the mixture spilt on the carpet. The rest splashed muddily on Gwinny’s legs and nightdress. Gwinny squealed again as she raced for the door. “It’s cold!” But she dared not stop to apologise. She continued racing, up the next stairs and into her little room on the top floor. She left behind her the most appalling smell. It was worlds worse than the one Malcolm had produced. It was so horrible that it awed them. They were staring at one another in silence, when Gwinny began to scream.

  “Caspar! Johnny! Caspar! Oh, come quickly!”

  CHAPTER TWO

  Caspar and Johnny pelted up to Gwinny’s room regardless of noise. Johnny thought she was on fire, Caspar that she was being eaten away by acids. They burst into the room and stood staring. Gwinny did not seem to be there. Her lamp was lit, her bed was empty, her window shut, and her doll’s house and all her other things arranged around as usual, but they could not see Gwinny.

  “She’s gone,” said Caspar helplessly.

  “No I haven’t,” said Gwinny, her voice quivering rather. “I’m up here.” Both their heads turned upwards. Gwinny appeared to be hanging from the ceiling. Her shoulders were lodged in the corner where the roof stopped sloping and turned into flat ceiling, her bony legs were dangling straight down beneath her, and her hands were nervously clasped in front of her. She looked a bit like a puppet. “And I can’t come down,” she added.

  “However did you get up?” demanded Johnny.

  “I sort of floated,” said Gwinny. “I went all light after that stuff splashed on me, and while I was getting into bed I got so light that I just went straight up and stayed here.”

  “Lordy!” said Johnny. “Suppose the window had been open!” It was a nasty thought. Both boys had visions of a light, leaf-like Gwinny floating out into the night and then up and up, unable to stop, like a hydrogen balloon.

  “Let’s get her down,” said Caspar. “Come on.”

  By standing on the bed, Caspar thought he could just reach Gwinny’s feet, if he jumped as he reached. Johnny stood in front of the bed to help catch her. Caspar got on the bed and jumped. His fingers brushed Gwinny’s feet, but he could not get a grip. To his annoyance, the slight push he had given her was enough to send Gwinny bobbing gently out into the middle of the room, quite out of reach.

  “Oh dear!” said Gwinny. “Could you lasso me or something?”

  Johnny took the cord off Gwinny’s dressing gown to try. But he remembered he had never been able to make a lasso that worked. “I’ll throw it,” he said. “You catch it. Both hands and carefully, mind.” He threw the cord upwards – quite a good shot. It hit Gwinny’s chest and slithered away down her legs. But Gwinny had always been hopeless at catching things. She missed the cord and went bobbing and twirling away towards the window with the movement.

  “That’s no good,” said Caspar. “She’ll be all night before she gets hold of it. Gwinny, can you work yourself along the ceiling, back over the bed, and I’ll have another go at catching you.”

  “I’ll try,” Gwinny said doubtfully. She put up one hand and pushed at the ceiling. The next moment, to the surprise of all three, she was swooping through the air towards the bed. Caspar raced after her, but, by the time he reached the bed, Gwinny had rebounded from the sloping roof and swooped out into the middle of the ceiling again. “Ooh!” she said, with her spiky head bobbing excitedly against the flex of the light. “That was ever such a nice feeling! I think I’ll do it again.” And, to Caspar’s exasperation, Gwinny began pushing with a hand here, then there, swooping this way and that and laughing. Johnny started to laugh too, because Gwinny looked like a gawky pink chicken with her nightdress and long bony legs.

  “We must make her stop being so silly,” Caspar said. “Gwinny,” he said to the soles of Gwinny’s swooping feet, “we’ve got to get you down. Don’t you understand? Suppose the Ogre finds you like that.”

  “He wouldn’t be able to catch me,” Gwinny said gaily, shooting from the window to the space above the door.

  “Yes he would,” said Caspar. “Think how tall he is.”

  “Yes, but Caspar.” said Johnny, “what’ll we do if we do get her down? Won’t she just shoot up again?”

  “We could tie her down,” Caspar suggested.

  “Oh no you won’t!” Gwinny called. She pushed off from the wall with her feet and floated on her back across the room, to the far corner. And there she lay, with her stomach and toes gently brushing the ceiling and a complacent smile on her face. “Try and catch me now,” she said.
>
  They saw it was no use expecting her to be sensible. “Do you think we could get rid of the chemicals somehow, and get her down that way?” Caspar said.

  “It might wash off,” said Johnny.

  “Let’s try,” said Caspar.

  They raced down two floors to the bathroom. There, Johnny seized the big mop that was used to wash the floor and Caspar seized the backbrush, and they hurried upstairs again. As they passed the door of Malcolm’s and Douglas’s room, they heard Douglas call out something about “herd of blinking elephants!” but they were too fussed to bother.

  Gwinny was lying on her back near the middle of the ceiling now. Johnny raised the dripping mop and aimed it for the part of Gwinny’s legs where he thought the chemicals had splashed. But it is not easy to aim a long, top-heavy mop. He hit Gwinny plumb on the backside. She shrieked, “Stop it! It’s cold!” and went floundering and scrambling and bobbing out of reach, like an upside-down pink crab, with a muddy splodge on the back of her nightdress. Caspar got on to the bed and clawed at her legs with the backbrush as soon as they came near.

  “Stop it, you beast!” said Gwinny, and scrambled back across the ceiling.

  Caspar jumped on to a chair on the other side of the room and tried to reach her there. Johnny lofted the mop and prodded at her as she passed. Gwinny squealed with silly laughter and scrambled out of reach again. They pursued her. Caspar went leaping from chair to bed and back again. Johnny charged this way and that, prodding, and Gwinny scuttled and squealed all over the ceiling. Then Johnny, not looking where he was going, kicked the doll’s house over with a crash, scattering little tables and chairs and doll’s house people all over the room.

  Gwinny turned over and drummed her heels on the ceiling, pointing furiously. “How dare you! Look what you’ve done! Pick them all up!”

  “You come and do it,” said Johnny cunningly.

  “I can’t, I can’t, I can’t!” said Gwinny, drumming away for all she was worth.

  There were footsteps, and the shattering voice of Douglas bawled from the stairs, “Stop that din, can’t you! Some of us are trying to do homework.”

  Gwinny’s heels stopped. Caspar and Johnny exchanged alarmed looks. Without a word, they got down and began collecting the chairs, tables and dolls. But the damage was done. Behind the feet of Douglas retreating, they heard a much more distant door slam. They waited. Heavy footsteps started upstairs. They galvanised Caspar. He leapt up, seized the mop and pointed it at Gwinny.

  “Quick! Catch hold of that, Gwinny, and don’t let go.”

  Gwinny was only too ready to do as he told her. She hung on to the wet end while Caspar heaved on the stick. It was extraordinarily hard work. Gwinny seemed a good deal heavier upwards, as it were, than she ever was on the ground. Johnny flung the last table into the doll’s house and helped Caspar heave. Slowly Gwinny was dragged down. Slowly and remorselessly the Ogre’s feet climbed the stairs. Once she was within reach, Gwinny was so terrified of rising again that she seized Johnny’s hair to hold herself down with.

  “What do we do now?” said Johnny, through a grin of agony.

  “Bed. The covers might hold her down,” gasped Caspar.

  They towed the floating Gwinny over to her bed and attempted to put her into it. Gwinny did her best to help, but nothing seemed to stop her floating away upwards every time they tried to put her legs between the sheets.

  The Ogre’s feet crossed the landing and began on the last flight.

  Gwinny flung her arms round Johnny in terror. While she was anchored that much, Caspar let go, picked up all the bedcovers, flung them over her floating legs and flung himself after them. As the Ogre’s feet came up the last stairs, Johnny jumped on to Gwinny too and sat on her stomach.

  When the Ogre tore open the door and stood glowering, he saw Gwinny in bed, Caspar sitting on one end of it, Johnny in the middle, and all their faces turned to him in not-quite-innocent alarm. The only thing out of place was the wet mop Gwinny seemed to be nursing and a muddy splotch on the pillow.

  “What the dickens are you all doing here?” said the Ogre.

  “Telling her a bedtime story,” said Caspar breathlessly.

  “Why does it need two of you and all this din?” demanded the Ogre.

  Caspar and Johnny could not think. Gwinny said brightly, “They were doing it with funny voices to make me laugh.”

  “Were they!” said the Ogre, “Well they can just stop!”

  “Oh no,” said Johnny. “We were just near the end. Can’t we just finish?”

  “No you just can’t,” said the Ogre. “Your mother and I are entitled to some peace.”

  “Please!” they chorused desperately.

  “Oh, very well,” said the Ogre irritably. “Five minutes. And if I hear another sound there’ll be trouble. What are you doing with that filthy mop?”

  Again neither Caspar nor Johnny could think. “It’s a broomstick,” said Gwinny. “The story’s about a witch.”

  “Then you can either do without or change the story,” said the Ogre. “I’m taking that back where it came from.” He strode over to the bed and tried to wrench the mop out of Gwinny’s hands. Gwinny lost her presence of mind and hung on to the mop with all her strength. The force with which the Ogre tore it free raised her a full foot off the bed and Johnny with her. Luckily, Johnny’s weight and Caspar’s were enough to bring her down again fairly quickly, and the Ogre did not notice their sudden elevation because his foot chanced, at that moment, to kick against the backbrush. He picked it up and looked at it meditatively. “I can think of a very good use for this,” he said. “Don’t tempt me too far.” Then he went away, taking the mop and the brush with him.

  They listened tensely to his retreating footsteps. When he had reached the bathroom, Caspar said, “Now what shall we do? We can’t sit here all night.”

  “But I’ll be cold on the ceiling,” Gwinny whimpered.

  “You could take a blanket up with you,” Caspar suggested.

  “If you could hold her down,” said Johnny, “I think I can fix her.”

  “All right,” said Caspar. “But don’t be too long.”

  So Johnny departed downstairs with heavy-footed stealth and Caspar tried to keep Gwinny in place. He found it next to impossible on his own. In a matter of seconds, she was floating clear of the bed, bedclothes and all.

  “Oh, what shall we do?” she wailed.

  “Shut up for a start,” said Caspar.

  The bedclothes slid away and Caspar was hanging on to Gwinny’s nightdress. There was a slow tearing sound. Gwinny whimpered and began to rise again, gently but surely. Caspar was forced to let go of her nightdress and catch hold of her ankles. There he hung on desperately. He found, in the end, that if he leant back, with his head nearly touching the floor and all his weight swinging on Gwinny, he could keep her floating upright about three feet from the floor. They had reached this point when Johnny came swiftly upstairs and entered the room with a bucket of water, looking very businesslike.

  “Oh good,” he said, when he saw the position Gwinny was in, and he threw the water over the pair of them.

  He had not thought to bring warm water. Gwinny squealed. Caspar gasped and nearly let go. He was about to say some very unkind things to Johnny, when he realised that Gwinny was now much easier to hold down.

  “It’s working,” he said. “Go and get some more.”

  Johnny turned, beaming with relief, and went galloping away downstairs, bucket clattering. Somewhat to Caspar’s annoyance, he did not stop at the bathroom, but went on galloping, right downstairs to the kitchen, because the water ran more quickly from the taps downstairs. Caspar shook his soaking hair out of his eyes and hung on grimly. Gwinny’s teeth chattered.

  “I’m freezing,” she complained. “My nightie’s soaking.”

  “I know,” said Caspar. “It’s dripping all over me, and I’m sitting in a puddle, if that’s any comfort.”

  After what seemed half an hour, they
heard Johnny pounding upstairs again. Caspar was too relieved to worry about the noise he was making. He just listened to Johnny pounding closer and closer and prayed for him to hurry. As Johnny’s feet crossed the landing below, a confused noise broke out on the same level. Johnny had started on the last flight of stairs, when Douglas erupted into another shattering roar.

  “What the blazes are you doing? There’s water pouring through our ceiling!”

  Johnny did not answer. They heard his feet climbing faster. Then came the feet of Douglas, pounding behind. Behind that again were other feet. Caspar and Gwinny could only wait helplessly, until the door at last crashed open and Johnny staggered in, red-faced and almost too breathless to move, with water slopping over his shoes out of the bucket.

  “Throw it,” Caspar said urgently.

  Johnny croaked for breath, heaved up the bucket and poured the water over Gwinny, drenching Caspar again in the process. It did the trick. Gwinny dropped like a stone and landed on Caspar. There was a short time when Caspar could not see much and was almost as breathless as Johnny. When he recovered sufficiently to sit up, Douglas was standing behind Johnny, looking as if he had frozen in the middle of shouting something, and behind him were the Ogre and their mother.

  “Johnny!” said Sally. “Whatever possessed you?”

  “Take him downstairs, Douglas,” said the Ogre, “and make him clear it up. These two can clear up here.”

  “Come on,” Douglas said coldly. Johnny departed without a word. There really was nothing to say.

  An hour later, when Gwinny had been put to bed in a clean nightdress and everywhere wet mopped dry, Caspar and Johnny went rather timidly into their room expecting to see the carpet, where the rest of the chemicals had gone, floating against the ceiling – or at least ballooning up in the middle. But the only sign of the spill was a large purple stain and a considerable remnant of bad smell. Much relieved, Caspar opened the window.

  “It must only work on people,” Johnny said thoughtfully.

  “We’d better clear it up,” said Caspar.
