‘Yeah,’ said Harry, surprised at what he considered

‘Yeah,’ said Harry, surprised at what he considered a great over-reaction. ‘But it's OK, I don't care, it's a bit of a relief to tell you the—’

‘I'm coming up there to have a word with Snape!’ said Sirius forcefully, and he actually made to stand up, but Lupin wrenched him back down again.

‘If anyone's going to tell Snape it will be me!’ he said firmly. ‘But Harry, first of all, you're to go back to Snape and tell him that on no account is he to stop giving you lessons—when Dumbledore hears—’

‘I can't tell him that, he'd kill me!’ said Harry, outraged. ‘You didn't see him when we got out of the Pensieve.’

‘Harry there is nothing so important as you learning Occlumency!’ said Lupin sternly. ‘Do you understand me? Nothing!’

‘OK, OK,’ said Harry, thoroughly discomposed, not to mention annoyed. ‘I'll ... I'll try and say something to him ... but it won't be—’

He fell silent. He could hear distant footsteps.

‘Is that Kreacher coming downstairs?’

‘No,’ said Sirius, glancing behind him. ‘It must be somebody your end.’

Harry's heart skipped several beats.

‘I'd better go!’ he said hastily and pulled his head backwards out of the Grimmauld Place fire. For a moment his head seemed to be revolving on his shoulders, then he found himself kneeling in front of Umbridge's fire with it firmly back on and watching the emerald flames flicker and die.

‘Quickly, quickly!’ he heard a wheezy voice mutter right outside the office door. ‘Ah, she's left it open—’

Harry dived for the Invisibility Cloak and had just managed to pull it back over himself when Filch burst into the office. He looked absolutely delighted about something and was talking to himself feverishly as he crossed the room, pulled open a drawer in Umbridge's desk and began rifling through the papers inside it.

‘Approval for Whipping ... Approval for Whipping ... I can do it at last ... they've had it coming to them for years ...’

He pulled out a piece of parchment, kissed it, then shuffled rapidly back out of the door, clutching it to his chest.

Harry leapt to his feet and, making sure he had his bag and that the Invisibility Cloak was completely covering him, he wrenched open the door and hurried out of the office after Filch, who was hobbling along faster than Harry had ever seen him go.

One landing down from Umbridge's office, Harry thought it was safe to become visible again. He pulled off the Cloak, shoved it in his bag and hurried onwards. There was a great deal of shouting and movement coming from the Entrance Hall. He ran down the marble staircase and found what looked like most of the school assembled there.
