From Azkaban To Hogwarts

William, who originally thought that this investigation would be as fruitless as last time, did not expect to receive good news from Filch just after the investigation began.

"There's no blood this time, just chicken feathers?"

"Yes, I carefully checked the ground outside the castle last night to make sure nothing was leaking there. It wasn't until I opened the door the next day that I discovered there were chicken feathers there."

The conscientious caretaker was pretty sure that because of Monday's bloody incident, he had been paying special attention to closing the castle gates these past few days.

"Great, Mr. Filch, we can now determine the time of the crime."

William patted the table excitedly, his tone full of uncontrollable joy.

"If that troublemaker is caught, I will definitely give him the best punishment - that guy must have walked through a secret passage, and I will catch that guy."

"Believe me, it will be soon. I have entrusted the students to check -"

"Entrusted students? Prefects?"

"No, those students in solitary confinement, believe me, they want to catch the troublemaker more."

There was an obvious conflict on Filch's face - he didn't agree with William's approach of using those students who made mistakes, but he also somewhat agreed with those guys who could find the secret passage.

"Okay, let them try. Anyway, if the investigation doesn't reveal anything, he will be detained for a day. If the investigation reveals that he should be arrested, he will be arrested."

The administrator mumbled reluctantly, which made William laugh a little, but he successfully concealed it by turning around and saying goodbye.

"See you then, Mr. Filch. Wait for my good news. I have a great idea. If there are no mistakes, it won't take long for us to catch that guy!"

William said goodbye and quickly left Filch's office.

‘If you go out in the middle of the night and take a secret passage, aren’t you waiting to be caught? ’

——

William knocked on the door of Professor McGonagall's office.

"Please come in."

"Professor William?" Professor McGonagall made a rather surprised sound when seeing William.

She only saw William at the dinner table at noon. Logically speaking, if she had anything to say at that time, even if it was an application form or the like, it would be impossible for her to come and submit it on Friday afternoon.

"Good afternoon, Professor McGonagall."

"Please sit down, what's the emergency?"

"I have two urgent matters. Professor McGonagall, if I want to hold a small banquet, is there any larger vacant venue in the school?"

"The banquet is a good choice." Professor McGonagall showed a rare smile, "All professors' offices can cast expansion spells, and there is no big limit on the area. You can also negotiate with the kitchen to purchase dishes at low prices. , In fact, professors often hold banquets, and the house elves will help take care of everything."

‘Expansion spell? It's something I haven't learned yet - if it really doesn't work, please ask Adams. He can't beat me anyway, so there won't be any shame if everyone is embarrassed. ’

As for asking for help from house elves, William was almost familiar with it. He could only say that the benefits of professors at Hogwarts were indeed very high.

"Well, there's one more thing."

"Please tell me, Professor William." Although he always had a serious face, Professor McGonagall's expression became obviously relaxed at this moment - it's not an emergency. As the head of Gryffindor, the other professors suddenly The students who came to her were probably the students from her college who had made some big mistake and even being put in jail was not enough.

"Well, what should I say, Professor, we have to start talking about this on Monday."

"Monday?" Professor McGonagall was stunned for a moment, and then remembered, "Monday - Professor William, are you referring to the big inspection caused by Hagrid's chicken dying?"

"Yes, Professor."

"Did they do it again?"

Professor McGonagall's answer was both helpless and skillful, which made people worry about what happened over the years.

"No, no, no, professor, I can't be sure. I just want to do an investigation. After this week's investigation, it was roughly determined that the person who committed the crime should have slipped out of the castle through a secret passage at night, and then took the chicken blood and chicken feathers. Left outside.”

"So, Professor William, you want to investigate who comes in and out of the lounge at night?"

"Is such that."

"Let me go too. She has a very stubborn personality. Except for Albus and me, I don't think she would tell anyone who asked her."

'If you are not stubborn, how can you become the gatekeeper of the Gryffindor common room? Guarding a student from the same house and anyone can ask is nothing. ’

Unfortunately, William did not dare to say this.

——

"Professor McGonagall!"

The portrait of the Fat Lady was unusually enthusiastic when she saw Professor McGonagall. It was completely different from the last time William came over to call the students. She had no intention of letting the professor in.

"good afternoon."

"Do you want to go in?"

The entrance to the lounge opened almost as soon as the question was asked.

"No, thank you. I'm not here to see students today, but to investigate something."

"I remember everything these days, Professor."

"Thank you, Fat Lady, who was out after lights out on Monday night?"

"I remember it very clearly..."

The fat lady quickly announced a long list of names without any intention of covering up for the students.

"It's so tragic. I guess Professor McGonagall usually turns a blind eye to this matter, but today these children are on the receiving end of a gun."

William, the culprit, had no idea that he had dragged Professor McGonagall into this investigation, and he only listened to the information below.

At this moment, many children had gathered around who were planning to go in, but they found that after Professor McGonagall investigated, they all stood there dumbfounded, not even daring to bite their ears.

"I have memorized these names and asked them to report to my office when they come back."

Professor McGonagall mercilessly sentenced those unlucky ones to death.

"So, what about last night? Did anyone try to leave the lounge after lights out last night?"

The professor asked with a normal expression.

"No, Professor, no one has attempted to enter or leave."

The fat lady was stunned for a moment, as if thinking about something, and finally answered decisively.

"No?"

William shouted in surprise, but immediately realized something was wrong - by shouting like this, didn't he conclude that the prisoner was in Gryffindor?

However, the same voice appeared in Professor McGonagall's mouth

"No?"

The professor's tone became calmer for the first time. She looked at the fat lady in confusion, "Are you sure?"

"I'm absolutely sure that after the lights went out last night, no one tried to leave the lounge and no one went in."

The scene suddenly became cold. Although the students around him showed curious expressions, Professor McGonagall immediately calmed down her expression.

"Everyone, stop watching and go back to the lounge - Professor William, come with me."
