Just a Defense Against the Dark Arts Professor

In the office, everyone's eyes turned to Sherlock.

Sherlock also came to his senses at this time, and he recalled the scene where Mr. Weasley and Malfoy got into a scuffle.

"Yes, I was there at the time." He said lightly, "Malfoy was mocking Mr. Weasley's family, and then they fought, and I went up to help and punched."

Suddenly, Professor McGonagall looked at Sherlock in disbelief, and even Dumbledore and Snape were a little surprised.

"You fought!" Professor McGonagall asked, raising his voice.

Sherlock said calmly: "What he said was ugly, and he wanted to insult my mother."

Hearing what Sherlock said, the three professors McGonagall showed their original expressions.

Indeed, according to the character of the original owner, he would not act easily at all.

At Hogwarts, the only two hands-on experiences of the original owner were that they were directly sent to the school hospital for three days.

When it comes to himself, there is no need for Ginny to go on, Sherlock directly said the following things.

"Malfoy was beaten hard by me. After he suffered a loss, he left immediately without staying in the bookstore..." Sherlock pondered the memory of that day, "but before he left, it seemed that The book is in Ginny's hands."

As soon as he said these words, everyone in the office found the point.

Professor McGonagall and Snape held their breaths.

Dumbledore looked at Sherlock expectantly.

"What about the book?"

"That book..." Sherlock looked at Ginny, who blinked at him.

"That book was in the pile of old books I threw back in the bookstore, and I bought Ginny a new set of textbooks as a gift for her."

"..."

The whole office fell silent.

Now everyone knew what the crux of the problem was, and even Sherlock himself knew who caused all these accidents.

Dumbledore, Professor McGonagall and Snape were speechless, as was Sherlock himself.

Who knew that he was just an inadvertent act of delivering books, which made things go so far.

Dumbledore sighed lightly, he could hear it, and he was very tired.

"The root of the matter should lie in the old book Sherlock put back. Lucius wanted to use that book to get revenge on the Weasleys. As a result, Sherlock made this accident happen, and the book was left in the It went to the bookstore, but someone else took it from the bookstore, bought it, and brought it to Hogwarts."

A smile gradually appeared on Professor McGonagall's face.

"That matter is easy now. As long as we inform the students and ask who among them bought a strange old book, then the source of the problem can be solved!"

But Dumbledore's expression didn't seem so optimistic. He tapped his fingers on the table and said softly.

"I can't tell you about the old books."

Professor McGonagall looked at Dumbledore in amazement, and Snape's expression was also quite puzzled.

Only Sherlock guessed why it couldn't be done.

"That old book is likely to be something that has its own consciousness. Since there has been an attack in the castle, it means that some students have been bewitched by him, or have been completely controlled by him. If we publicize the old book at this time. Going out, not only will you not find the book, but you will also startle the snake and let the person who opened the secret room know in advance that we have found him."

After Sherlock finished analyzing, Dumbledore looked at him with more surprises.

"The way you see things is very different from before." He said approvingly, "I look forward to your changes after this school year is over."

Sherlock bowed his head slightly, as if to indicate that Dumbledore was over the top.

Seeing that they were still in the mood to talk about these things, Professor McGonagall couldn't help turning black, and she asked eagerly.

"It can't be publicized, so how do we find that old book? We can't let things continue like this. No student has died because of this, but no one can guarantee it!"

Dumbledore waved his hand, indicating that Professor McGonagall did not need to be so anxious, and he told the countermeasures to be implemented next.

"Tonight, on the grounds of vigilance and the search for the hidden murderer in the castle, the students are gathered in the auditorium. Sherlock, Severus, Minerva, and Pomona, the four of you search the lounges of the four academies. , don't let the prefect intervene in the middle."

"In the auditorium, I will arrange for Filius and Filch to ask the students what they were doing when Malfoy was attacked. It is best to find the book."

After everything was assigned, Sherlock, Professor McGonagall, and Snape left the headmaster's office together.

Professor McGonagall frowned and went to arrange for the students to gather in the auditorium, while Sherlock and Snape stood in front of the door and looked at each other.

Sherlock has rarely dealt with Snape since the beginning of the year.

Because he didn't know how to characterize Snape.

He knew very little about the original book, so he couldn't figure out whether this outward expression, obviously not so friendly, was a good or bad potions professor.

"I'll check the boys' dormitories of Slytherin and Hufflepuff, you go to Gryffindor and Ravenclaw." Snape coldly divided the tasks between him and Sherlock.

Of course, Sherlock said that there was no problem. It was the same for him in which academy's dormitory he checked.

Just when the two were about to separate, Snape suddenly asked indifferently.

"Do you think you can find that old book today?"

Sherlock froze. Although he didn't know why Snape asked him this, he had really thought about it seriously.

"There is a high chance of finding it." Sherlock's voice was equally indifferent. "There was an attack today. The student who was controlled by the old book should not have time to hide it in a sufficiently concealed place."

This was indeed what he really thought.

But there are other reasons that make him confident.

Although his existence disrupted the original plot, it was precisely because of his appearance that Dumbledore and the professors at Hogwarts knew more clues about the attack in advance.

In the original book, it should be finally revealed that the monster in the secret room is a basilisk.

No one knew in advance that all this was triggered by an old book.

After mastering so many clues, Dumbledore immediately took action, and Sherlock felt that there was a good chance that the problem could be solved this time.

"Hopefully it's really what you say it is."

Snape turned and left the headmaster's door.
