Sherlock Holmes at Hogwarts.

Chapter 339 The Angel of Vengeance
In the principal's office, Sherlock paced back and forth, speaking at double speed:
"No one could have imagined that Voldemort would become so weak because of an infant that he would disappear without a trace."

In this situation, no matter how much Peter regretted it, it was too late to change anything.

He was cornered by the enraged Sirius Black and forced into a desperate situation.

It was at this moment that he finally revealed the 'intelligence' that had always been overshadowed by the brilliance of others.

When speaking of "intelligence and wisdom," Sherlock deliberately emphasized his words:

"In the presence of eyewitnesses, he deliberately spoke loudly, distorted facts, and framed Sirius for betraying the Potters."

Taking advantage of Sirius's rage, he suddenly made his move, faked a suicide, and transformed to escape.

Even Sirius Black, the vengeful angel, was fooled.

Although I never had any contact with Sirius Black, based on the descriptions of several professors and the events that have occurred over the years, it is still clear that he was an arrogant and self-important fellow.

That's why when the Ministry of Magic came to arrest him, he didn't resist and willingly stayed in Azkaban for twelve years.

I think this is because he felt he bore an undeniable responsibility for the deaths of Harry's parents, especially since he believed Peter was already dead, and thus chose this method to atone for his sins.

“Holmes, you are right this time. Black is indeed a self-important and annoying fellow.”

Snape practically spat out those words through gritted teeth.

McGonagall and Lupin both looked at him, but Snape paid no attention.

At that moment, only one thought occupied his mind:
None of this would have happened if Sirius hadn't suggested that Lily change her secret agent.

Holmes gave Snape a deep look, then looked away and continued:

"To hear the latest news from the wizarding world, Peter, who became a mouse, chose to run to the Weasley family, a pure-blood wizarding family, and become their children's pet, lying low in silence."

If Voldemort were to disappear from this world, he could comfortably live as a chubby rat who eats and sleeps, and sleeps and eats.

If Voldemort rises again, then he can make a powerful comeback.

Twelve years later, Sirius discovers Peter's secret, his anger ignites, and he breaks out of prison to find Harry.

At this point, Sherlock turned to Harry, "Remember that line, 'He's at Hogwarts'?"
At the time, everyone, including myself, thought Sirius was talking about you, but in fact, he was talking about Peter Pettigrew.

What happened next is something we all experienced firsthand.

Sirius Black successfully escaped from prison, leaving Peter in constant fear.

Finally, on the eve of Halloween, Sirius Black successfully arrived at Hogwarts.

People thought he had been imprisoned for too long and had forgotten the time.

In fact, he chose a time when none of the students were in their dormitories to go find Scabbard, who existed as Ron's pet.

Unfortunately, without the password, he was unable to enter the Gryffindor Tower, and in a fit of rage, he tore the Fat Lady apart.

In my opinion, this is just as foolish a decision as persuading the Potters to change their secret agent and not tell anyone else.

Of course, his behavior further confirmed to me that Banban was Peter.

After that, my friends and I brought Banban here and invited all the teachers over.

As it turns out, my deduction was correct; the entire case was a logically connected and uninterrupted chain.

"Brilliant reasoning, Sherlock."

Dumbledore stared at Sherlock and said:
"You brought the truth that had been buried for twelve years back to the surface, not only bringing the real culprit to justice but also saving an innocent life. Hogwarts was also able to resume its normal teaching order. On behalf of the school and the Order of the Phoenix, I sincerely thank you."

Professor McGonagall and Professor Lupin both nodded.

Like Dumbledore, they also recognized Sherlock's enormous contribution to this matter.

Professor Snape, however, did not comment on the matter and instead asked directly, "Where is Sirius?"

"Still at school."

Sherlock said confidently, "He won't leave until Peter is caught."

Therefore, my suggestion is to contact the Ministry of Magic as soon as possible and reveal the truth.

On the one hand, it was to clear Sirius's name, lift the arrest warrant for him, and free him from having to hide anymore.

On the other hand, it is about determining Peter's crimes, making a judgment, and giving justice to the innocent victims.

The professors exchanged glances and nodded silently.

Sherlock's advice is exactly what's needed right now.

Just then, Dumbledore suddenly turned to Harry and asked, "Harry, what do you think?"

"Ah I?"

Harry was taken aback; he hadn't expected Dumbledore to ask for his opinion.

"Although Voldemort is the real murderer of your parents, Peter... do you think this is the right way to treat him?"

"Principal, you might as well just ask Potter whether you should just kill this worm."

Professor Snape sneered, "You asked such a subtle question; Potter's dull mind can't possibly understand it!"

“No, don’t—!”

Upon hearing Snape's words, Harry immediately shook his head and said, "My parents wouldn't want to see his friends become murderers, especially for people like this!"

"I'm not your parents' friend..."

Snape blurted out the words instinctively, then realized his mistake and quickly stopped himself.

He looked at Sherlock.

Sure enough, the perceptive young man was looking at him with a meaningful gaze.

The look in his eyes, which seemed to see through everything, made him feel increasingly frustrated.

Sherlock couldn't help but find it somewhat amusing.

Are you already planning to do it yourself?
And his instinctive act of protecting Harry just now—this professor is really hypocritical!
but……

Sherlock's eyes narrowed suddenly.

Now it seems that Snape's secret is far more complex than it appears.

Once this matter is over, he will probably have to investigate Snape thoroughly.

Although he had promised Professor Flitwick not to pry into other people's secrets, judging from the current situation, Snape's secret is closely related to the fate of his friend.

In that case, we can't just leave it unattended.

Although he didn't know why, Snape felt a chill run down his spine, as if he had suddenly been targeted by something.

Once Harry agreed to the way Peter was dealt with, the rest was no longer the concern of the four young wizards.

Dumbledore politely asked them to leave, explaining that what Sherlock had just said was only a preliminary outline, and they still had much to do.

However, as soon as they stepped out of the office, they heard some urgent voices behind them:
"Wait, wait a minute!"

Professor Lupin chased after them and came out, saying, "I asked Mr. Dumbledore for a few minutes of my time."

He looked at Sherlock as he spoke, and then bowed deeply to him.

This behavior greatly surprised the three friends besides Sherlock.

Harry couldn't help but ask, "Sir, what's this?" "It's to express my gratitude."

Sherlock was well aware of Lupin's thoughts and said:
"But I don't think you need to do that. Harry, Ron, and Hermione are all my friends."

Unfortunately, Ron will lose his pet after this incident.

Upon hearing Sherlock's words, Harry's eyes immediately welled up with tears, Ron's eyes also reddened, and Hermione grabbed Sherlock's hand.

"No, you don't understand."

Lupin shook his head. "I know Sirius and Little Pettigrew, or rather, I used to think I knew them."

But... I didn't expect things to turn out this way.

Whether it's Sirius or Little Pettigrew, I cannot accept it if either of them betrays their friend.

Upon hearing Lupin's words, the young wizards all fell silent.

Admittedly, the truth surfaced prematurely due to Sherlock's forceful intervention, but the result was that the traitor went from being a good friend to another good friend.

Just as Lupin said, no matter who that person was, he felt bad.

“You have cleared Sirius’s name, and I think he should be able to meet Harry soon—as Harry’s godfather.”

Hearing Professor Lupin's words, Harry looked up in surprise, only to see Lupin wink at him.

"By the way, Sherlock, I think you already knew my identity before Peter told you about this, right?"

"good."

"Was it discovered while writing the paper Professor Snape assigned?"

"No, I didn't write that paper at all."

Sherlock chuckled. "When he unusually called on me to answer questions in class, I already knew what was going on."

He would be very happy.

Professor Lu Ping's smile was tinged with embarrassment. "He assigned that paper hoping someone would consider what my symptoms might mean..."

"Unfortunately, besides me, only Hermione noticed this."

"Sherlock, how could you..."

Hermione looked at Sherlock in surprise, "I haven't even told you yet!"

"You were checking the lunar phase chart a couple of days ago."

Sherlock turned to his side and said with a smile, "My dear Hermione, you're the only student who finished that paper."

Hermione: ()
Harry, Ron, Lupin: |(*′口`)
Sherlock: "Actually, some clues had already been revealed before the start of the school year:"
On the Hogwarts Express, you're not feeling well, which is around the time of the full moon.

During that Boggart lesson, Harry also asked me why I was afraid of a crystal ball, when nobody actually realized it was the moon.
Then there's the time Professor Snape covered your classes, and your weakened physical condition when you returned.

So even if Professor Snape didn't say anything, you can still make inferences by putting these clues together.

"You are the smartest little wizard I have ever met, Sherlock."

Lupin said sincerely, "No, you should drop the 'little'. Even among adult wizards, there are few who are smarter than you."

"Thank you for your compliment, Professor Lupin."

Harry and Hermione both noticed that Sherlock felt pleased when he saw Lupin's genuine admiration.

As for Ron, he was still immersed in the sad story of his pet being a living person.

"Sir, I suggest you consider resolving this issue as soon as possible."

Even a fool would start to overthink things if he saw you leaving at the same time every month.

If you were a woman, it would be understandable to experience discomfort for a period of time every month.

"..."

"Not to mention, there are people like Professor Snape who would love for your identity to be discovered."

"I can understand him."

Professor Lu Ping remarked with considerable emotion:
"Actually, he has helped me a lot. Since I enrolled, he has been helping me prepare wolfsbane medicine."

I think you should know that this medicine is not only expensive in terms of raw materials, but also very difficult to prepare.

Although he was always against me coming to teach at the school and always thought I would help Sirius get into the school, he still prepared this rare potion for me every month after Headmaster Dumbledore agreed.

If it weren't for this colleague, I would be in even more pain than I am now.

Ah, it's almost time, I have to go back...

Today is such a happy day!
Get some rest, and sweet dreams!

After Professor Lupin left, Ron looked around and then awkwardly said to Hermione:
"I'm so sorry, Hermione, I'm really, really sorry about what happened at Crook Hill..."

Hermione was taken aback, seemingly not expecting Ron to apologize on his own initiative.

She held back for a few seconds, but seeing Ron's sincere expression, she quickly lost her composure.

"No, I was also at fault in this matter."

Hermione looked at Crookshanks in her arms. "Although I was right in the end, I failed to put myself in his shoes..."

"Who would have thought that Banban was actually a human, and such an ugly and disgusting man at that..."

Ron said with a sigh of relief, "I think if Mom and Dad find out about this, they might buy me an owl, right?"

After the truth came out, the two finally reconciled.

The four walked and talked. Harry tried several times to ask Sherlock a question, but Ron was so excited that he kept talking and didn't get a chance to speak.

Even after returning to his dormitory, Ron did not stop.

Seeing that it was getting late, Harry could only suppress the thought for the time being.

The next day, when Sherlock took Neville out for his morning exercise, Harry, who was prepared, immediately said:
"I also need to go!"

“But Harry…Sirius Black…”

Neville looked at Harry in surprise and said weakly, "Didn't the teachers forbid you from going outdoors?"

"The ban has been lifted!" Harry exclaimed triumphantly. "We're safe now!"

"what?"

Neville looked at Harry, puzzled, then at Sherlock.

"Let's go. You haven't participated in training for a while. Let's see if your fist and sword skills have fallen behind."

"it is good!"

Harry said confidently.

Although he hadn't been able to participate in the morning training sessions initiated by Sherlock during this period, thanks to Wood, the Quidditch training still served to improve his physical fitness.

So after resuming morning exercise, his performance was passable.

While Neville was fencing alone as Sherlock had instructed, Harry finally found an opportunity to ask the question he had been wanting to ask all day yesterday.
