From Azkaban To Hogwarts

William was a little confused until he reached Professor McGonagall's office.

'Not Gryffindor? Who could that be? ’

He was not surprised that there were flaws in the investigation - he had seen many prisoners in Azkaban, and he had no stereotypes about any academy. Anyway, he had seen prisoners from every academy.

Just as William was thinking about how to investigate the access to the lounges of the other colleges, Professor McGonagall, who had made sure to close the office door, suddenly burst into emotion.

"Unprecedented! Attack the lounge guard! Use a confusion spell or other spells to erase your schedule! What on earth do these senior bastards want to do!"

"Flying to school late for the start of school! Forming a group to cause trouble! Randomly ransacking the administrator's office! It's only been less than a month since school started!"

…

"Sorry, Professor William, I made you laugh."

The originally stern and intimidating vice-principal gave William the impression that no strangers should be allowed in when he got angry. At this moment, he even felt that he had discovered an existence more terrifying than a dementor.

Fortunately, he probably had enough self-control because of the anger of the Gryffindor students. After losing his temper loudly, the professor finally calmed down.

"Confusion spell?"

William finally had time to ask his doubts.

It's not that he doesn't know the Confusion Curse, but he really doesn't know how Professor McGonagall figured it out.

Although traces of the use of magic can be detected, this is obviously ineffective against the guards in the lounge - the number of times the lounge is opened in this day is enough to erase all the evidence. Maybe a wizard can see it, but that is definitely not the case. William.

"Of course, the confusion spell or other spells are used from inside the lounge. Unless Albus personally takes action, no one can directly break the protective magic of the lounge."

Professor McGonagall, who had regained her composure, was finally able to sit down. She used her wand to pull another chair for William on the opposite side.

"Please take a seat, Professor William."

William sat down eagerly - he was really curious about how Professor McGonagall could see the confusion spell that had been erased by countless movements of magic.

This is not something that can be read in a magic book. He will never be able to access such high-end skills even if he studies on his own for another year.

"Kill the rooster and let out the blood. Evil sacrifice. Professor William, do you have anyone to doubt?"

"I initially suspected that it was a prank by the Weasley brothers, but they had no motive for committing the crime a second time. The questioning just now erased the time when they committed the crime. But if it is mixed with a confusion spell, these inferences will be invalid. However, , Professor - how did you tell that the portrait of the Fat Lady was cast by a confusion spell or something like that?"

Professor McGonagall thought about it and quickly came to a conclusion.

"It shouldn't be them. I know the strength of the Weasley brothers. They can't cast such a powerful confusion spell. They are very smart, but they put their minds on other places - as for the confusion spell, I can only say, Professor William, you don’t know much about Gryffindor.”

Professor McGonagall gave a rather forced smile - obviously, she didn't seem proud of it.

'don't know? We have two cells, one for one in the one on the left, one for two in the one on the right, and one in the cell opposite. I have been in prison with them for more than half a year. Do you think I don’t understand? ’

Perhaps seeing William's doubts, Professor McGonagall supplemented his words.

"In Gryffindor, it is common for students to sneak out. No one comes out, which makes people curious. Those children sneaked out and walked around the castle even on the eve of the OWLs exam. How could they appear? A night when no one sneaks out?”

"What's more, Wood didn't leave my office until lights out last night - that kid was applying for a few nimbuses a week ago with hospital fees, and said that 2,000 nimbuses are enough!"

‘Nimbus? ’

William was stunned for a moment, and then immediately remembered that it was the famous brand of broomsticks - there was no doubt that Professor McGonagall did not approve it.

‘I seem to be using funds to treat students to meals. This is too…. 'An irrelevant thought came to William's mind - although he knew it was time to be serious now, he really couldn't get nervous anymore.

Although he is still helpless about the attack, the vice-principal Professor McGonagall has approved his investigation, which means that Dumbledore, known as the first white wizard, will most likely participate.

Even though he knew that it was better to seek help from others than to ask for yourself, William still had the feeling that he had suddenly found a supporter - the matter of a student killing a chicken couldn't be more difficult to deal with than trying to get someone from Azkaban, right?

"Professor William, do you have other suspects?"

While William was thinking wildly, Professor McGonagall, who saw his relaxed expression, couldn't help but ask questions.

"Other suspects? Well - if it's a senior, then it's most likely a sixth grader."

William, who was interrupted from his random thoughts, quickly answered. He had doubts when he ruled out the Weasley brothers.

"Fifth grade students should not have time to commit crimes. When I assigned homework, I checked the homework of other subjects to ensure that they had enough time to complete it. However, after completing those homework, I don't think they are still capable of doing it. Do other things - the homework has been collected. Although there is a slight phenomenon of plagiarism from each other, it is not the kind of copying to the end. Fifth graders have no time to commit crimes. "

"Plagiarism?"

Professor McGonagall's eyes turned cold.

"A few understandable references, Professor."

William quickly explained, and Professor McGonagall's face looked much better.

"In the seventh grade, it's easy for them to apply for an internship as long as they find a job. To get the blood pressure of a rooster, you don't have to take such a big risk to kill Hagrid's chicken. But I don't rule out that some people want to The possibility of doing something big before graduation.”

"That is to say, Professor William, your opinion is to focus on the sixth and seventh graders."

"Well, that's the professor, but I don't rule out the possibility that juniors may have committed the crime."

William thought for no reason about the introduction on the card he drew from Professor Snape - before he entered school, he had mastered a curse that most graduates had never mastered.

"You mean, the person who used the confusion spell to erase everyone's records might be a low-level student who doesn't know much about school?"

"Well, I don't rule out the existence of geniuses. If it is Principal Dumbledore, I believe he will have this ability in the first grade."

"But there is only one Albus -" Professor McGonagall showed a rare smile, "But if you insist, we can ask Professor Lockhart, who among the younger students has shown amazing talent in magical self-defense classes. "
