Out on the stone steps, Harry turned to the others.
“Right, here’s what we’ve got to do,” he whispered urgently. “One of us has got to keep an eye on Snape—wait outside the staff room and follow him if he leaves it. Hermione, you’d better do that.”
“Why me?”
“It’s obvious,” said Ron. “You can pretend to be waiting for Professor Flitwick, you know.” He put on a high voice, “‘Oh Professor Flitwick, I’m so worried, I think I got question fourteen b wrong…’”
“Oh, shut up,” said Hermione, but she agreed to go and watch out for Snape.
“And we’d better stay outside the third floor corridor,” Harry told Ron. “Come on.”
But that part of the plan didn’t work. No sooner had they reached the door separating Fluffy from the rest of the school than Professor McGonagall turned up again and this time, she lost her temper.
“I suppose you think you’re harder to get past than a pack of enchantments!” she stormed. “Enough of this nonsense! If I hear you’ve come anywhere near here again, I’ll take another fifty points from Gryffindor! Yes, Weasley, from my own house!”
Harry and Ron went back to the common room, Harry had just said, “At least Hermione’s on Snape’s tail,” when the portrait of the Fat Lady swung open and Hermione came in.
“I’m sorry, Harry!” she wailed. “Snape came out and asked me what I was doing, so I said I was waiting for Flitwick, and Snape went to get him, and I’ve only just got away, I don’t know where Snape went.”
“Well, that’s it then, isn’t it?” Harry said.
The other two stared at him. He was pale and his eyes were glittering.
“I’m going out of here tonight and I’m going to try and get to the Stone first.”
“You’re mad!” said Ron.
“You can’t!” said Hermione. “After what McGonagall and Snape have said? You’ll be expelled!”
“SO WHAT?” Harry shouted. “Don’t you understand? If Snape gets hold of the Stone, Voldemort’s coming back! Haven’t you heard what it was like when he was trying to take over? There won’t be any Hogwarts to get expelled from! He’ll flatten it, or turn it into a school for the Dark Arts! Losing points doesn’t matter anymore, can’t you see? D’you think he’ll leave you and your families alone if Gryffindor wins the house cup? If I get caught before I can get to the Stone, well, I’ll have to go back to the Dursleys and wait for Voldemort to find me there, it’s only dying a bit later than I would have, because I’m never going over to the Dark Side! I’m going through that trapdoor tonight and nothing you two say is going to stop me! Voldemort killed my parents, remember?”
