'Oh, yeah,' said Hagrid brightly. 'Glad yeh found the place all righ'! Well, as you can see — or, I dunno — can you? We're doin' Thestrals today — '

'I'm sorry?' said Professor Umbridge loudly, cupping her hand around her ear and frowning. 'What did you say?'

Hagrid looked a little confused.

'Er — Thestrals!' he said loudly. 'Big — er — winged horses, yeh know!'

He flapped his gigantic arms hopefully. Professor Umbridge raised her eyebrows at him and muttered as she made a note on her clipboard: 'Has . . . to . . . resort . . . to . . . crude . . . sign . . . language. '

'Well . . . anyway . . .' said Hagrid, turning back to the class and looking slightly flustered, 'erm . . . what was I sayin?'

'Appears . . . to . . . have . . . poor . . . short . . . term . . . memory, ' muttered Umbridge, loudly enough for everyone to hear her. Draco Malfoy looked as though Christmas had come a month early; Hermione, on the other hand, had turned scarlet with suppressed rage.

'Oh, yeah,' said Hagrid, throwing an uneasy glance at Umbridge's clipboard, but ploughing on valiantly. 'Yeah, I was gonna tell yeh how come we got a herd. Yeah, so, we started off with a male an' five females. This one,' he patted the first horse to have appeared, 'name o' Tenebrus, he's my special favourite, firs' one born here in the Forest — '

'Are you aware,' Umbridge said loudly, interrupting him, 'that the Ministry of Magic has classified Thestrals as "dangerous"?'

Harry's heart sank like a stone, but Hagrid merely chuckled.

'Thestrals aren' dangerous! All righ', they might take a bite outta yeh if yeh really annoy them — '

'Shows . . . signs . . . of. . . pleasure . . . at . . . idea . . . of. . . violence, ' muttered Umbridge, scribbling on her clipboard again.

'No — come on!' said Hagrid, looking a little anxious now. 'I mean, a dog'll bite if yeh bait it, won' it — but Thestrals have jus' got a bad reputation because o' the death thing — people used ter think they were bad omens, didn' they? Jus' didn' understand, did they?'

Umbridge did not answer; she finished writing her last note, then looked up at Hagrid and said, again very loudly and slowly, 'Please continue teaching as usual. I am going to walk,' she mimed walking (Malfoy and Pansy Parkinson were having silent fits of laughter) 'among the students' (she pointed around at individual members of the class) 'and ask them questions.' She pointed at her mouth to indicate talking.

Hagrid stared at her, clearly at a complete loss to understand why she was acting as though he did not understand normal English. Hermione had tears of fury in her eyes now.

'You hag, you evil hag!' she whispered, as Umbridge walked towards Pansy Parkinson. 'I know what you're doing, you awiul, twisted, vicious — '

'Erm . . . anyway,' said Hagrid, clearly struggling to regain the flow of his lesson, 'so — Thestrals. Yeah. Well, there's loads o' good stuff abou' them . . .'

'Do you find,' said Professor Umbridge in a ringing voice to Pansy Parkinson, 'that you are able to understand Professor Hagrid when he talks?'

Just like Hermione, Pansy had tears in her eyes, but these were tears of laughter; indeed, her answer was almost incoherent because she was trying to suppress her giggles.

'No . . . because . . . well . . . it sounds . . . like grunting a lot of the time . . .'

Umbridge scribbled on her clipboard. The few unbruised bits of Hagrid's face flushed, but he tried to act as though he had not heard Pansy's answer.

'Er . . . yeah . . . good stuff abou' Thestrals. Well, once they're tamed, like this lot, yeh'll never be lost again. 'Mazin' sense o' direction, jus' tell 'em where yeh want ter go — '

'Assuming they can understand you, of course,' said Malfoy loudly, and Pansy Parkinson collapsed in a fit of renewed giggles. Professor Umbridge smiled indulgently at them and then turned to Neville.

'You can see the Thestrals, Longbottom, can you?' she said.

Neville nodded.

'Who did you see die?' she asked, her tone indifferent.

'My . . . my grandad,' said Neville.

'And what do you think of them?' she said, waving her stubby hand at the horses, who by now had stripped a great deal of the carcass down to bone.

'Erm,' said Neville nervously, with a glance at Hagrid. 'Well, they're . . . er . . . OK . . .'

'Students . . . are . . . too . . . intimidated . . . to . . . admit . . . they . . . are . . . frightened, ' muttered Umbridge, making another note on her clipboard.

'No!' said Neville, looking upset. 'No, I'm not scared of them!'

'It's quite all right,' said Umbridge, patting Neville on the shoulder with what she evidently intended to be an understanding smile, though it looked more like a leer to Harry. 'Well, Hagrid,' she turned to look up at him again, speaking once more in that loud, slow voice, 'I think I've got enough to be getting along with. You will receive' (she mimed taking something from the air in front of her) 'the results of your inspection' (she pointed at the clipboard) 'in ten days' time.' She held up ten stubby little fingers, then, her smile wider and more toadlike than ever before beneath her green hat, she bustled from their midst, leaving Malfoy and Pansy Parkinson in fits of laughter, Hermione actually shaking with fury and Neville looking confused and upset.

'That foul, lying, twisting old gargoyle!' stormed Hermione half an hour later, as they made their way back up to the castle through the channels they had made earlier in the snow. 'You see what she's up to? It's her thing about half-breeds all over again — she's trying to make out Hagrid's some kind of dimwitted troll, just because he had a giantess for a mother — and oh, it's not fair, that really wasn't a bad lesson at all — I mean, all right, if it had been Blast-Ended Skrewts again, but Thestrals are fine — in fact, for Hagrid, they're really good!'

'Umbridge said they're dangerous,' said Ron.

'Well, it's like Hagrid said, they can look after themselves,' said Hermione impatiently, 'and I suppose a teacher like Grubbly-Plank wouldn't usually show them to us before NEWT level, but, well, they are very interesting, aren't they? The way some people can see them and some can't! I wish I could.'

'Do you?' Harry asked her quietly.

She looked suddenly horrorstruck.

'Oh, Harry — I'm sorry — no, of course I don't — that was a really stupid thing to say.'

'It's OK,' he said quickly, 'don't worry'

'I'm surprised so many people could see them,' said Ron. 'Three in a class — '

'Yeah, Weasley, we were just wondering,' said a malicious voice. Unheard by any of them in the muffling snow, Malfoy, Crabbe and Goyle were walking along right behind them. 'D'you reckon if you saw someone snuff it you'd be able to see the Quaffle better?'

He, Crabbe and Goyle roared with laughter as they pushed past on their way to the castle, then broke into a chorus of 'Weasley is our King'. Ron's ears turned scarlet.

'Ignore them, just ignore them,' intoned Hermione, pulling out her wand and performing the charm to produce hot air again, so that she could melt them an easier path through the untouched snow between them and the greenhouses.

December arrived, bringing with it more snow and a positive avalanche of homework for the fifth-years. Ron and Hermione's prefect duties also became more and more onerous as Christmas approached. They were called upon to supervise the decoration of the castle ('You try putting up tinsel when Peeves has got the other end and is trying to strangle you with it,' said Ron), to watch over first— and second-years spending their break-times inside because of the bitter cold ('And they're cheeky little snot-rags, you know, we definitely weren't that rude when we were in first year,' said Ron) and to patrol the corridors in shifts with Argus Filch, who suspected that the holiday spirit might show itself in an outbreak of wizard duels ('He's got dung for brains, that one,' said Ron furiously). They were so busy that Hermione had even stopped knitting elf hats and was fretting that she was down to her last three.

'All those poor elves I haven't set free yet, having to stay here over Christmas because there aren't enough hats!'

Harry, who had not had the heart to tell her that Dobby was taking everything she made, bent lower over his History of Magic essay. In any case, he did not want to think about Christmas. For the first time in his school career, he very much wanted to spend the holidays away from Hogwarts. Between his Quidditch ban and worry about whether or not Hagrid was going to be put on probation, he felt highly resentful towards the place at the moment. The only thing he really looked forward to were the DA meetings, and they would have to stop over the holidays, as nearly everybody in the DA would be spending the time with their families. Hermione was going skiing with her parents, something that greatly amused Ron, who had never heard of Muggles strapping narrow strips of wood on to their feet to slide down mountains. Ron was going home to The Burrow. Harry endured several days of envy before Ron said, in response to Harry asking him how he was going to get home for Christmas: 'But you're coming too! Didn't I say? Mum wrote and told me to invite you weeks ago!'

Hermione rolled her eyes, but Harry's spirits soared: the thought of Christmas at The Burrow was truly wonderful, though slightly marred by Harry's guilty feeling that he would not be able to spend the holiday with Sirius. He wondered whether he could possibly persuade Mrs Weasley to invite his godfather for the festivities. Even though he doubted whether Dumbledore would permit Sirius to leave Grimmauld Place anyway, he could not help but think Mrs Weasley might not want him; they were so often at loggerheads. Sirius had not contacted Harry at all since his last appearance in the fire, and although Harry knew that with Umbridge on constant watch it would be unwise to attempt to contact him, he did not like to think of Sirius alone in his mother's old house, perhaps pulling a lonely cracker with Kreacher.

Harry arrived early in the Room of Requirement for the last DA meeting before the holidays and was very glad he had, because when the torches burst into flame he saw that Dobby had taken it upon himself to decorate the place for Christmas. He could tell the elf had done it, because nobody else would have strung a hundred golden baubles from the ceiling, each showing a picture of Harry's face and bearing the legend: 'HAVE A VERY HARRY CHRISTMAS!'

Harry had only just managed to get the last of them down before the door creaked open and Luna Lovegood entered, looking as dreamy as usual.
