Harry could see Hagrid watching

Harry could see Hagrid watching anxiously out of his cabin window. When Harry's examiner, a plump little witch this time, smiled at him and told him he could leave, Harry gave Hagrid a fleeting thumbs-up before heading back to the castle.

The Astronomy theory paper on Wednesday morning went well enough. Harry was not convinced he had got the names of all Jupiter's moons right, but was at least confident that none of them was inhabited by mice. They had to wait until evening for their practical Astronomy; the afternoon was devoted instead to Divination.

Even by Harry's low standards in Divination, the exam went very badly. He might as well have tried to see moving pictures on the desktop as in the stubbornly blank crystal ball; he lost his head completely during tea-leaf reading, saying it looked to him as though Professor Marchbanks would shortly be meeting a round, dark, soggy stranger, and rounded off the whole fiasco by mixing up the life and head lines on her palm and informing her that she ought to have died the previous Tuesday.

‘Well, we were always going to fail that one,’ said Ron gloomily as they ascended the marble staircase. He had just made Harry feel rather better by telling him how he had told the examiner in detail about the ugly man with a wart on his nose in his crystal ball, only to look up and realise he had been describing his examiner's reflection.

‘We shouldn't have taken the stupid subject in the first place,’ said Harry.

‘Still, at least we can give it up now.’

‘Yeah,’ said Harry. ‘No more pretending we care what happens when Jupiter and Uranus get too friendly.’

‘And from now on, I don't care if my tea-leaves spell die, Ron, die—I'm just chucking them in the bin where they belong.’

Harry laughed just as Hermione came running up behind them. He stopped laughing at once, in case it annoyed her.

‘Well, I think I've done all right in Arithmancy,’ she said, and Harry and Ron both sighed with relief. ‘Just time for a quick look over our star-charts before dinner, then ...’

When they reached the top of the Astronomy Tower at eleven o'clock, they found a perfect night for stargazing, cloudless and still. The grounds were bathed in silvery moonlight and there was a slight chill in the air. Each of them set up his or her telescope and, when Professor Marchbanks gave the word, proceeded to fill in the blank star-chart they had been given.

Professors Marchbanks and Tofty strolled among them, watching as they entered the precise positions of the stars and planets they were observing. All was quiet except for the rustle of parchment, the occasional creak of a telescope as it was adjusted on its stand, and the scribbling of many quills. Half an hour passed, then ar hour; the little squares of reflected gold light flickering on the: ground below started to vanish as lights in the castle windows were extinguished.

As Harry completed the constellation Orion on his chart, however, the front doors of the castle opened directly below the parapet where he was standing, so that light spilled down the stone steps a little way across the lawn. Harry glanced down as he made a slight adjustment to the position of his telescope and saw five or six elongated shadows moving over the brightly lit grass before the doors swung shut and the lawn became a sea of darkness once more.

Harry put his eye back to his telescope and refocused it, now examining Venus. He looked down at his chart to enter the planet there, but something distracted him; pausing with his quill suspended over the parchment, he squinted down into the shadowy grounds and saw half a dozen figures walking over the lawn. If they had not been moving, and the moonlight had not been gilding the tops of their heads, they would have been indistinguishable from the dark ground on which they walked. Even at this distance, Harry had a funny feeling he recognised the walk of the squattest of them, who seemed to be leading the group.

He could not think why Umbridge would be taking a stroll outside after midnight, much less accompanied by five others. Then somebody coughed behind him, and he remembered that he was halfway through an exam. He had quite forgotten Venus's position. Jamming his eye to his telescope, he found it again and was once more about to enter it on his chart when, alert for any odd sound, he heard a distant knock which echoed through the deserted grounds, followed immediately by the muffled barking of a large dog.

He looked up, his heart hammering. There were lights on in Hagrid's windows and the people he had observed crossing the lawn were now silhouetted against them. The door opened and he distinctly saw six sharply defined figures walk over the threshold. The door closed again and there was silence.
