Now the whole of Hogsmeade is full of patrolling Aurors.

Sherlock had encountered three investigations when he walked towards Hogwarts, including Tonks.

She had just left her internship, and her main task should be to do odd jobs in the office, but now she is really short of people, so she was sent out.

Such a large number of Aurors gathered in Hogsmeade, of course, not just to catch the murderer from Germany, but to arrest Black.

After all, although seven known attacks have occurred, five of them are Muggles, and the wizard has only two died now, which is not enough to overshadow Black's escape from prison.

But anyone who knows the inside story knows that the attack is actually much more troublesome than Black's affairs.

Because of this case that occurred in the UK, the British Aurors have not grasped any key clues so far, and the most important information lies in the three German Aurors.

Sherlock didn't know if the German Ministry of Magic shared the murderer's information with the British.

When it comes to arresting Black, they can only think of waiting around Hogwarts and finding the murderer of the attack, it seems that he is also going to attack Hogsmeade.

Both things gathered in Hogwarts, which made the semester of this year feel a sense of urgency before the start of school.

Sherlock walked to the end of Hogsmeade Street, and just as he was about to walk towards the gate of Hogwarts, he suddenly found a large black dog curled up next to the trash can in an alley.

The dog looked like a stray dog, but it was very big and had smooth fur. You could tell at a glance that it was carefully raised and abandoned later.

The dog caught his attention for a short time. Sherlock was not an animal welfare enthusiast and had no intention of adopting it.

After walking into the gate of Hogwarts, the school was still deserted at this time, but the figure of the dementor could already be seen on both sides of the gate.

When Sherlock entered the door, they floated over and wanted to check on him.

He did not resist this, and the two dementors stared at his face, as if confirming whether he was the Black who escaped.

At this moment, a cold and desperate aura suddenly spread from one of the dementors. Sherlock could clearly feel the temperature on his body being dropped, and at the same time, the positive and positive emotions in his body were being sucked out.

The moment he noticed the problem, he did not hesitate and directly pulled out his magic wand!

"Hushen Guard."

Silver glory wins!

Countless silver light threads gushed out from the tip of his wand!

The two dementors suddenly let out silent screams, and the gray robes on their bodies were constantly eroding with the continuous erosion of silver light threads.

It was not until their bodies had begun to become illusory and could be completely wiped out at any time that they could barely get rid of the entanglement of those silver light threads.

They floated away in a mess, and didn't even dare to look back at Sherlock.

"Things that bully the weak and fear the strong." Sherlock sneered.

Judging from the current performance of these dementors, he can be sure that if they have been stationed near Hogwarts, there will be chaos this semester.

They are used to being bold and arbitrary, and here they are not like Azkaban, who always have food rations to fill their stomachs, so they are very likely to make extreme actions.

However, Sherlock doesn't need to worry about this matter for the time being, Dumbledore should understand this matter better than him.

Sherlock walked into the castle. As soon as he arrived at the foyer on the first floor, he met Professor McGonagall with a frown and a head as if he was thinking about something.

"Good morning, Professor McGonagall." Sherlock greeted.

When Professor McGonagall saw him, his brows immediately stretched out, and she had a gentle smile that would not normally appear on her face.

"Good morning, Sherlock. You're here just in time. After you put the things in place, you need to go to the principal's office. The password is lemonade. Albus has something to come to you."

Sherlock nodded and signaled that he knew.

He and Professor McGonagall separated in the foyer and came to his office on the third floor to put things in place.

Even though I haven't come back for two months, there is nothing to clean here. The house elves in the castle have taken on their usual cleaning work.

Then he walked out of the office and walked along the corridor on the third floor to the end, in front of the stone monster at the entrance of the principal's office.

"Correction." The stone monster asked in a muffled voice.

"Lemonade." Sherlock replied.

In fact, it is very simple to sneak into the principal's office. Just talk about the sweets Dumbledore likes to eat, and one of them must be an accurate password.

The stone monster jumped away from the entrance and made way for him.

Sherlock walked in, then walked along the spiral stairs to the eighth floor, and pushed the door open and walked into the principal's office.

Dumbledore was lying in the seat with his eyes closed, as if thinking about something.

The principals in the portrait by the wall were still making subtle snoring, as if they couldn't wake up at any time, while Fox was combing his bright red feathers with his sharp beak on the golden branches beside him.

After hearing the movement, Dumbledore opened his eyes and looked at Sherlock who was walking in with a smile on his face.

"You're doing well this holiday?"

Sherlock sat opposite Dumbledore, and a cup of steaming black tea appeared in front of him.

"It's really good. I'm fine in France. The food over there is much better than the one here."

"I received a letter from Nick, in which he told me all the story. You and Harry actually got the French Wizard Friendship Medal issued by the French Ministry of Magic."

Dumbledore looked a little surprised. Obviously, at the beginning he didn't expect Sherlock to take Harry to experience that.

Sherlock waved his hand and said.

"We didn't expect that something would happen. The thief who steals the wand is really bold. Even Nick Lemay dares to pretend. If he hadn't wanted to be a human trafficker and had me discovered the problem, he might have succeeded."

They talked about their experiences during the holidays for a while, and then Dumbledore spoke out the reason for finding him.

"When you arrived in Hogsmeade, you should have seen what happened there."

Sherlock nodded =.

"The troubles are piled up, and the problems are all happening in Hogwarts."

Dumbledore's blue eyes became deeper, and the half-moon-shaped eyes reflected white light.

"Blake's matter is pretty easy to resolve, but the attack was a big trouble."

He obviously sees it clearly than most people.

"You have seen that lady Shilk last semester. She came to Hogwarts to find me at the front end and said she wanted to stay in the castle temporarily."

Sherlock frowned.

"She thought the murderer would come to Hogwarts."

"It's not that she thinks." Dumbledore shook his head and said with a deep meaning, "but that she will come to Hogwarts when she sees that."

Sherlock was slightly stunned.

Dumbledore's words seemed a bit inexplicable, but Sherlock remembered that at the end of last semester, he saw the true face of Ms. Shilk in front of the two graves in the Forbidden Forest.

What he remembers most was the pair of eyes blindfolded by ribbons.

"She is...a master of prophecy?"

"In some ways, she can see more than we do." Dumbledore didn't say it explicitly, but in fact he had already admitted what he said in disguise.

Sherlock asked in confusion.

"Last time I was curious, wasn't she a German wizard? Why would you promise to be buried in the forbidden forest of Hogwarts?"

Hearing Sherlock's question, Dumbledore's face showed a look of remembrance, and he whispered.

"Ms. Shilk's father was once the Auror of the British Ministry of Magic. He died on duty more than a decade ago. It was her mother who brought her to Germany."

After hearing Dumbledore talk about this, Sherlock did not ask any more questions.

Auror, who died on duty more than a decade ago, could still make Dumbledore show such an expression, and that he might have died in the struggle with Voldemort.

Then there would be nothing strange about agreeing to bury his tomb in the forbidden forest.

"I agreed to her request to stay in Hogwarts, but also asked her to have someone follow her when investigating the case."

"This is also what Fudge asked me. He was not at ease with these three German wizards. They repeatedly asked the German side to share the information of the murderer with them, but the German Ministry of Magic was always looking for excuses to delay."

"The Ministry of Magic's Aurors are in short supply now. They not only need to investigate Black's affairs, but also maintain normal order in the magic world. So he hopes that I can send a professor to monitor their movements at all times in case they will do anything that is harmful to the interests of the British magic world."

Sherlock understood Dumbledore's meaning and chose the watcher for him.

"What should I do when I teach in school?"

Dumbledore obviously made arrangements.

"Your assistant coach, Remus Lupin, is probably already on Hogwarts Express. With him on your teaching task, you won't be so heavy, and you will have more time to distract from other things."

Speaking of this, Dumbledore suddenly said with a smile.

"I also want to congratulate Sherlock. Under your teaching last year, the students all achieved excellent results in the Black Magic Defense Technology in the Ordinary Wizard Level Test and the Ultimate Wizard Level Test last semester. Each of them is above A, and more than 80% of the students even got O and E (from high to low, O, E, A (pass line), P, D, T)."

"So I suggest that this year's Black Magic Defense Class teaching, you can focus on the upper grades. Those students have a lot of pressure on the exams, and the lower grade classes are temporarily handed over to Lupin."
