Sherlock Holmes at Hogwarts.

Chapter 335 It is Peter

"Aside from this one, this spyscope has issued three warnings in total."

In the Hogwarts Headmaster's office, Sherlock paced back and forth, speaking calmly and patiently.

Under the watchful eyes of four professors and three students, he slowly extended three fingers:

“I didn’t see it the first time. Ron wrote to Harry that the Weasleys, a family of nine, were the only people around it.”

Bill Weasley, who works in Egypt, concluded that it was a counterfeit product sold to witch tourists because he felt there was no one in his family who could not be trusted.

However, Ron pointed out that it was because the Weasley twins had put beetles in Bill's soup.

In other words, Ron believed that the people he didn't trust at the time were the Weasley twins.

Harry and Ron were both taken aback by Sherlock's words.

So much time has passed that they've all forgotten about it.

I didn't expect Sherlock to remember.

Hermione frowned and began to think.

Sherlock said that "Ron believed the Weasley twins were the untrustworthy ones," does that mean the truth is not so?
"The second time was on the Hogwarts Express."

Sherlock pointed to the four young wizards as he spoke, "Besides the four of us, Professor Lupin was also in that carriage."

Upon hearing Sherlock's words, Professor Lupin's expression changed drastically. He gripped the armrests of his chair tightly, then quickly released them.

Snape sneered, narrowing his eyes as he looked Sherlock up and down, seemingly trying to discern something from him.

Dumbledore and Professor McGonagall exchanged another glance, but this time they said nothing.

"As Mr. Dumbledore said, I trust my friend and I trust Professor Lupin."

Sherlock met Lupin's gaze.

Professor Lu Ping felt relieved and said sincerely:
"Thank you, Sherlock."

"You're welcome, Professor. For that very reason, I, like Professor McGonagall, also suspected that the endoscope might be damaged—Ron once mentioned that the owl's long journey had caused it some problems."

But when Harry and Ron took it to Hogsmeade for a checkup, they were told that it was not broken.

That would make Bill's claim seem more credible—that these were counterfeit goods sold to wizard tourists…

but! "

Upon hearing this crucial turn of events, everyone's eyes were fixed on Sherlock.

They knew that Sherlock was about to reveal the answer.

"Just recently, it sounded the alarm again."

This was also the smallest group we'd ever had; there were only four of us students in the dormitory.

This experience made me realize something, a detail we had overlooked for a long time, and it brought the alarm logic of this little gadget to the surface.

Sherlock's gaze swept over his three companions, lingering particularly on Ron for a moment.

Ron looked completely bewildered, having no idea what Sherlock meant.

The others had similar expressions, wondering what Sherlock was really up to.

Only Hermione vaguely realized something.

Sherlock had her bring Crookshanks, and Ron brought Scabbers to the headmaster's office. They'd previously said it would completely resolve the cat-and-mouse conflict... Could it be...?

She turned sharply to Sherlock, about to speak, but someone beat her to it:
“Sherlock Holmes, this roundabout game should end. If you continue to waste time in this foolish way, I think I can leave immediately.”

Professor Snape stared intently at Sherlock, his impatience and disgust evident in his eyes.

"Please be patient, Severus."

Professor Lupin smiled once again to help Sherlock out of the predicament, his white hair at his temples gleaming softly in the firelight.

"Sherlock's reasoning is like brewing a mild remedy. If you heat it too fast, it will boil over. Only by stirring it slowly can the effects of each ingredient be blended just right."

Snape's gaze suddenly shifted to Lupin: "Professor Lupin, you seem to know a lot about Sherlock Holmes?"

“Just as Sherlock trusts me, I trust him just as much,” Professor Lupin said, still smiling.

Sherlock nodded to Lupin, then turned to another teacher present:

"Professor McGonagall, do you remember the story you told us a few days after Halloween?"

“Of course I remember,” Professor McGonagall said, looking at the table with a stern face. “So, is that related to it?”

The miniature spy scope kept rotating, emitting light, and whistling, stubbornly asserting its presence.

"It's obvious."

Sherlock's gaze swept over everyone present once more, and he slowly said:
"Little Pettigrew intercepted Blake and cried out in front of the whole street:"

'Lily and James, Sirius, how could you do this? How could you do such a thing?'

Then he drew his wand, but unfortunately, Black was far more agile and blasted Pettigrew to pieces.

Sherlock stopped at the Memory Loft and repeated Professor McGonagall's last words verbatim.

This made Professor McGonagall's face turn very unpleasant, because she was reminded of the hero she had once scolded.

Professor Lupin's body trembled slightly; he seemed even more excited than Professor McGonagall.

Snape looked at Dumbledore, who nodded slightly to him. Harry and Ron both knew they couldn't repeat the words verbatim like Sherlock, but they didn't understand why Sherlock was bringing it up.

Hermione's surprise grew stronger.

"Unfortunately, neither you, nor Mr. Dumbledore, nor Professor Hagrid have all forgotten to tell me one thing."

At this point, Sherlock's gaze sharpened.

“The brave Peter Pettigrew, the great hero who was blown to pieces by the evil Sirius Black, left behind the largest piece of his remains, which was a finger.”

Dumbledore and Professor McGonagall were both taken aback by what they heard.

"That's true."

Professor McGonagall's eyes flickered slightly, a hint of reminiscence in them, as she slowly spoke:
"That finger was given to his poor mother as a keepsake, along with the Order of Merlin, First Class."

This is... truly heartbreaking. That child and his mother suffered so much; I didn't want to recount those cruel details.

She frowned slightly, her voice filled with reluctance.

"No! This is precisely the most crucial thing!"

Sherlock suddenly raised his voice, “Dear Professor McGonagall, the truth often lies hidden in the details that are overlooked, like a gem hidden in the dust.”

He clasped his hands together, resting his chin on them, and leaned back slightly.
"During this period, I devoted myself to the investigation of this case and visited many people for this purpose."

During my conversation with Professor Luping, he happened to mention this matter.

He looked at Lu Ping, his gaze carrying a hint of inquiry.

"That's what happened."

Lupin nodded slightly, a few strands of white hair swaying gently with the movement.

But then he frowned slightly, a hint of confusion flashing in his eyes. "I don't understand, how could this finger possibly be related to the case?"

Sherlock's lips curled into a slight, confident smile. He shook his head and said:
"But have you ever wondered why the explosion site could precisely leave a finger symbolizing Peter's death, while shattering the other debris into pieces?"
Of course, this was also due to my oversight. When I was talking to Professor McGonagall, I forgot to tell her not to overlook any details.

In the past, when I asked people with inside knowledge to recount the details of a case, I always made a point of emphasizing this point.

He narrowed his eyes slightly, as if replaying the details of past cases in his mind.

"Because often the most inconspicuous little things can become the key to solving the mystery, just like finding the key piece in a messy jigsaw puzzle, instantly making the whole picture clear."

Harry, Hermione, and Ron all nodded.

Sherlock has indeed always had this habit.

"Fortunately, justice prevails, and after I obtained this crucial information from Professor Lu Ping, along with..."

Sherlock pointed to the miniature sight mirror that was still glowing, spinning, and whirring, and said slowly, "The last piece of the puzzle is finally complete!"

At this point, he slowly took Ron's pet, Scabbers, from his pocket and placed it on the table.

The moment Hermione saw Scabbers, Crookshanks in her arms suddenly let out a low growl, his claws gripping her sweater tightly, his yellow eyes burning with rage.

Hermione quickly hugged it tightly.

As the owner of Scabbers, Ron was the most confused one at this moment.

He is now completely confused about the situation.

At first, they said they were going to solve Scabbers' problem, but as they talked, they drifted to the spyglass they gave to Harry, then to the case from twelve years ago, and now they've finally come back to Scabbers.

Now that Banban has been brought out, but... why does the atmosphere feel a little off?

Sherlock pressed Scabbers down with one hand and said proudly:

"Ladies and gentlemen, let me introduce you to the hero who was presumed dead twelve years ago—Mr. Peter Pettigrew. He lived for twelve years in the form of a rat named Scabbers, and it was he who caused this spyglass to sound the alarm time and time again!"

Everyone was stunned.

Time seemed to freeze at that moment, and everyone present was stunned for several seconds as if they had been petrified.

Sherlock's victorious expression and his resounding announcement of the results remained vivid in the memories of everyone present for many years to come.

After a moment of silence, Professor Snape was the first to let out a sharp, explosive sound:

"Ridiculous! Absurd! Holmes, don't you want to look at what you're saying?"
Do you really think you can overturn the Ministry of Magic's investigation report, sealed with Merlin's seal, based solely on a sick, mangy rat?

He suddenly turned to Lupin and said with a disdainful look, "Professor Lupin, the so-called remedy you mentioned is this fairy tale that the great detective transplanted into his brain."

What do you mean by a mouse? Peter Pettigrew is still alive... Look at this mouse he pulled out!
It's less like Peter Pettigrew and more like a tattered rag the Weasleys use to wipe tables!

Ron let out a choked roar, because Harry had covered his mouth tightly.

Because he was pulling so hard, his fingernails, which were gripping Ron's arm, almost dug into Ron's arm.

It was clear that Professor Snape was now on guard, and he was determined not to let Ron clash with the other party.

After saying this, Snape turned to Dumbledore and said in a deep voice:

"You certainly don't believe a single word of the stories Sherlock Holmes tells, do you?"

Sirius Black showed he could be a murderer when he was sixteen, you haven’t forgotten that, have you, Headmaster?

I think you haven't forgotten that he once tried to kill me, have you?

The fact that Snape even brought this up shows that he was truly on the verge of losing his composure at that moment.

How could someone killed by Sirius Black still be alive?!
