On the first of September, Fudge sent an Auror from the Ministry of Magic to take Harry to King's Cross Station. Because Sirius Black has not yet been caught, some protective measures are still necessary.

Just as Blake was reluctant to go to Diagon Alley, he thought it would be easier to follow Harry to Hogwarts, where not only Dumbledore was there, but also Professor McGonagall, an Animagus registered with the Ministry of Magic, both of whom were masters of Transfiguration. Whichever one he encountered, Blake was not sure that he would be able to pass as Dark.

Harry was helpless, but Aitch said he had a way to take care of Blake, and that he could take him with him when it was time to go to Hogsmeade. After Harry had fed Blake breakfast, he suspiciously got into the car with Edge.

The Hogwarts Express is always full, and the carriages are full from the beginning to the end. Since it was from Privet Road, Aitch and Harry, like last year, got on the train to the sound of the horn as it departed. They had to make their way to the back of the car, and now only the last car was available.

There was only one person in the carriage, sitting by the window, asleep. Harry and Aitch stopped at the threshold. The Hogwarts Express is usually used by students, who have never seen an adult here, except for the witch who pushes the food cart for them.

The stranger was wearing an extremely worn wizard's robe, patched in several places. He looked sick and exhausted. He still looks young, but his pale brown hair is already mixed with gray hair.

"Gentlemen, you're almost late again." Hermione had a ginger cat in her arms, and her words were tinged with anger.

"It's okay, it's just a little bit." Aitch snorted, "How did you get here?" I saw you and Ginny and they had a good conversation. While Harry and Aitch were looking for empty seats, Hermione was still hanging out with the rest of the Gryffindors.

They sat down, closed the door, and sat as far away from the windows as possible so as not to disturb the sleepers.

"You know Ron's rat is sick, right?" Hermione was angry when she mentioned it, "It's nature to catch cat and mouse, and Crookshane doesn't always stay with it, so you want to live with me when you come to Hogwarts." ”

"You didn't see Ron's baby dead rat, and he wanted to throw Crookshank off the train."

"Don't do that, Hermione. After all, Crook Hill is also at fault. Harry argued for Ron, "Since I came back from Egypt, I've heard that Spotted (Ron Mouse's name) is so sick that the Magniquet medicine doesn't work. ”

"Also, who do you think he is?" Harry asked the two of them, stiffly changing the subject.

“R． Professor J. Lupin. Hermione immediately whispered, as if someone was going to rob her.

"How do you know?"

"Didn't he say it on his box?" Aitch replied, pointing to the luggage rack over the man's head, where there was a small, worn-out box, tied with many ropes and neatly knotted.

“R． Professor J. Lupin: "The words are printed in the corner of the box, and the letters have peeled off.

"I don't know what he teaches?" Harry said, frowning at the lifeless silhouette of Professor Lupin.

"Obviously," Hermione whispered, "there's only one empty seat, isn't it?" Defence Against the Dark Arts class. ”

They already had two teachers who taught the course, both of whom had only been teaching for a year. They began to talk about Lockhart's incompetence and talked about third-grade class selection.

"Oh my God, Hermione, can you learn so many classes?" Harry was shocked by the sheer energy of the top student when he heard that she had chosen divination, Muggle studies, and arithmetic divination.

"Of course." Hermione proudly raised her head like a little swan in protest at Edge. She believes that she will definitely win Aitch in this year's exam.

In the evening, the train continued northward, and the rain became heavier; The window panes were now a thick, sticky gray that deepened until the lights in the hallway and on the luggage racks came on. The train swayed, the rain knocked on the windows, the wind howled, but Professor Lupin was still sleeping.

"We're probably getting there." Harry said, leaning over to look at Professor Lupin, who was leaning against the window that was now completely dark. As soon as he finished saying this, the train slowed down.

"We can't get there." Hermione said, looking at her watch.

"Then why did it stop?" Harry sat down uneasily.

The train is getting slower and slower. The sound of the wheels was quieter, and the wind and rain outside the window were louder. Harry was closest to the door, getting up to check the hallway. In the carriages on the side of the corridor, there were people peeking out. The train shook suddenly, stopped, and a "popping" sound could be heard in the distance, indicating that the luggage had fallen from the shelf. Then, all of a sudden, all the lights went out, and they were thrown into complete darkness.

"Don't move." Aitch lit up the carriage with a fluorescent charm, and several people lit their wands in the same way.

Professor Lupin seems to have finally woken up. "Stay where you are, don't move." His voice was hoarse. He stood up slowly, but before he could get to the door, it slowly opened.

Standing in the hallway, illuminated by the fluorescent spell in the hands of several people, was a cloaked, ceiling-high monster. This is the Dementor. Its face is completely hidden under the turban.

Harry's eyes went down, and what he saw made his stomach tighten: a hand came out of his cloak, it shimmered, gray, thin, and crusted, like something had died, soaked in water and rotted, and it had taken less than a second to appear. The Dementor under the cloak seemed to sense Harry's gaze, and the hand suddenly shrank into the folds of the black cloak.

Then, it gasped, long, slow, and trembling, as if trying to suck in something other than air from its surroundings.

They all felt a chill run over their bodies. Harry felt his breath freeze in his chest. The chill penetrated his skin, down to his chest, to his heart, Harry's eyes rolled upwards, he couldn't see anything, he was drowning in the cold, his ears were surging, like water rushing, he was pulled down, and the sound in his ears was louder......

Then, from a distance, he heard screams, terrible, frightened, pleading screams......

Suddenly, "Calling the Divine Guard!" ”

Then there was an eagle's cry, and a silver-white goshawk shot out of the tip of Edge's wand, pushing the Dementor headlong into the ceiling of the carriage, interrupting its movement to absorb happy memories from the crowd.

Out of Professor Lupin was a silvery-white wolf that slammed into the Dementors falling from the ceiling, driving them from the back of the car to the front of the car.

"Harry, Harry......" Hermione hurriedly picked up Harry, who was limp on the ground, desperately calling his name.

"Don't worry, Hermione." Aitch took a piece of chocolate from his pocket and fed it to Harry's mouth, "I think it's just a loss of strength, and I'll be fine in a while." ”

"Edge? Ravenclaw's heir? Professor Lupin put away the chocolate he had just taken out again, "Very nice Patronus Charm." ”

"Thank you, Professor, for the compliment." Aitch helped Hermione lay Harry on the seat and gave Hermione a chocolate too.

"I'm going to talk to the driver." Professor Lupin must have thought that nothing would happen again, and left Harry in the care of Edge.
