"Why don't we just tell Dumbledore about this?" Magos didn't quite understand Harry's idea of preparing his own investigation, and despite his reputation, there were really few wizards who bought his account.

Ron nodded his head after releasing his rat out of the dormitory, for fear that Harry would not be able to think of it.

"I don't want to trouble him anymore, since Sirius is coming for me, then I should take matters into account."

"Have you ever thought that this might cause him more trouble?"

Harry lowered his head slightly, after the baptism of the first and second years, how could he not understand this truth, especially since Dumbledore had invited Moody to protect him secretly last year. But it was about his father, and he would never be sure who his father's killer was if he hadn't verified Sirius himself.

Seeing that Harry didn't respond, McGoth had to say something different.

"Since Sirius is sure that Peter Pettigrew is hiding at Hogwarts, we can first determine if he is actually at school."

"How do we find it?" Harry responded this time.

"Try this." Magos said as he pulled out a map of the living spots.

Harry's spirit shook, apparently remembering the name magic on it.

"I solemnly swear that I have not done anything good."

As the map of the living spots appeared, Ron looked at the first few pseudonyms.

"I'm curious about who Moonface, Wormtail, Big Feet, and Pointed Fork are capable of making such useful and complex magic items."

"We'll always know." Magos said casually, and Harry couldn't care less about their conversation, staring at every name that appeared on the map.

For a long time, Harry didn't know whether he was disappointed or angry, or if he was relieved that he couldn't find it.

"He lied to me." Harry said as he looked at his two friends who were still looking.

"But why did he let us go?" Ron rubbed his sour eyes, a little puzzled.

"Maybe his purpose wasn't to kill me, but to trick me into ambush... The mystery man goes. Seeing Ron's scared expression, Harry had no choice but to call him something else.

"Don't be so sure." McGoth focused on the specks that were scurrying around outside the dormitory, but his name hadn't changed at all, and he reckoned that Harry had a prerequisite for seeing Peter's name.

"The Living Point Map, while useful and powerful, is undeniably not omnipotent, at least last year it failed to show Salazar. Slytherin's Chamber of Secrets and Basilisk. ”

"But how else can we find Peter?" Harry was already less hopeful, believing more that Sirius had deceived him. He was going to ask Mr. Weasley about Sirius.

"Two ways."

"Two more?" Ron looked surprised, he hadn't even thought about using the dot map.

"First, Dobby. Harry said that Dobby now works at Hogwarts, and that we can ask him to ask the house-elves in Hogwarts to help, and that there is nothing in the school that can be hidden from them. ”

"If even the house-elves can't spot Peter, then either Sirius is lying, or Peter is hiding too well. Of course, we also have clues to focus on investigating the rats in Hogwarts, which is an unlikely task for us, but not a difficult task for house-elves. ”

"What if you don't get any clues in the end."

"That's the second option, tell Headmaster Dumbledore."

Harry frowned,

"I know Headmaster Dumbledore is very powerful, but since my father was killed and he didn't show up to defend Sirius, that doesn't mean that he either didn't know the whereabouts of Pettigrew-Peter, or that Sirius was a traitor."

Magos nodded in agreement with Harry's words,

"Indeed, if I hadn't heard about a magic item like this in the school from Jokoni in Hogsmeade, I wouldn't have come up with this idea." Saying that, he told them to wait for a while, find the surveillance item that Jokowi gave him from the magic bag, and then tell them what the item does.

"Isn't that the same as a live map?" Ron muttered.

"It should be stronger, and if there is such a prop, it is most likely to be in the hands of the headmaster."

Harry couldn't make up his mind after listening to McGoss's words, and to be honest, he didn't pay any better attention, and his only source of information was to ask Ron's father about Pettigrew-Peter and Sirius. Blake and his father's past. And then judging from it, if Peter and Sirius can be confronted face to face, the credibility is undoubtedly high.

"I'll go find Dobby." Harry hesitated for a moment, but he didn't want to trouble Dumbledore.

McGoth couldn't help it.

"Then let's ask the professors about them, I think since they used to be friends with your father, they should have attended Hogwarts before, and the professors should know something about them."

Harry didn't hesitate this time, nodded his head and said thank you.

"Who made us friends." Magos patted him on the shoulder and smiled.

Then, before the Quidditch match, Harry asked Dobby, who was so happy that Dobby could help Harry that he jumped up and down for a while before disappearing.

"Hopefully they'll find it."

The next day, Lupin gave the Defence Against the Dark Arts lesson to Snape, who explained werewolves as soon as he came up. McGoth thinks this is the stupidest thing Lupin has ever done, Snape is willing to make you potions, but that doesn't mean he doesn't hate you, now all the little wizards here know more or less how to distinguish between werewolves and how to suppress werewolves.

As is customary, Snape found an excuse to deduct Gryffindor points, and then began to scold Harry and Hermione, followed by Neville. McGoth was tired of watching this bad taste, and I really couldn't understand why Snape was so happy.

But there was a difference between today and the past, and after Snape had finished all his daily routine, he suddenly called McGoth up.

"Mr. Will, tell me what you would do if you met a werewolf."

McGoth stood up and thought about it.

"Running faster than anyone else?"

The classroom was stunned for a moment, then burst into laughter. Snape's face was gloomy and dripping, apparently not expecting him to say the answer.

That's your answer? Escape with the life of someone slower than you? ”

Seeing that Snape was really angry, McGoth had no choice but to explain the methods in the book.

"There is no new idea and no choice of life and death." Snape snorted coldly.

"Werewolves are bloodthirsty and agile, but they have a lethal trait, their sanity is replaced by wildness after transforming into werewolves, and it is difficult to cast spells, and this is your chance to pierce their hearts with spells."
