Just a Defense Against the Dark Arts Professor

"That cat is very smart. It can understand what I say and can express clearly to me what it sees."

"It tried to catch Peter countless times before, but failed to find a chance. Later, Peter faked his death and ran away from the boy again in front of it. It told me the whole situation and even helped me steal one. A piece of paper with the entrance code to the Gryffindor lounge, so I can go in and confirm it myself."

"A few days ago, I sneaked into the Gryffindor common room again. Peter did escape. He is no longer with the boy."

Hearing Sirius's story, Sherlock frowned unconsciously.

"If Peter ran away, would he still be at Hogwarts?"

"Yes! He definitely didn't leave!" Sirius said gloomily, "Not only can the cat feel that he is still here, but according to his character, he will not escape from here!"

"When I was staying in Azkaban, the other Death Eaters who were imprisoned in Azkaban were gnashing their teeth with hatred towards him. They thought that it was because of his information that Voldemort finally lost his power and they were captured. ”

"Peter himself obviously knows this. With his timid character, he will definitely leave a way out. If Voldemort can come back later, then he can use Harry to do something to ensure that he is safe. His status there. Harry is his other life-saving straw, and he won't let go so easily!"

Sirius' analysis made sense, and Sherlock also touched his chin and thought.

"You can try the Marauder's Map. We never thought that Peter would be in the castle before, so we didn't pay attention to whether his name appeared on the map. But if he is still in the castle, we can definitely find him on the map. , if there is no map, but it can be confirmed that Peter is still at Hogwarts..."

Sherlock turned his gaze back to the Forbidden Forest, and Sirius and Lupine followed his gaze.

"Then the most likely place for him to hide is in this forest." Lu Ping finally said in a deep voice.

Sirius asked, staring at them.

"The Marauder's Map? Didn't I remember that Filch had taken away that thing a long time ago? Not long after we finally left the school?"

Sherlock also looked at Sirius.

"Did you get this map when you were in school?"

Lupine shook his head and smiled bitterly.

"Sorry Sherlock, I haven't had time to tell you about this. The Marauder's Map was actually drawn by us. After Sirius and the others learned about the Animagus, Hogwarts Castle was no longer useful to us. What's the secret? We walked through all the secret passages, then drew them all, used magic on them, and finally became the Marauder's Map."

Sherlock also suddenly realized this.

"It turns out that the makers shown on the map are the four of you, Moony, Padfoot, Prongs and Wormtail."

Lupine then helped answer Sirius' questions.

"The Marauder's Map later fell into the hands of the Weasley twins, and then they gave it to Harry. A few days ago, Snape caught Harry using the map to go to Hogsmeade from the secret passage, and I found the name of the producer on the map, so he called me over, and I took the opportunity to take the Marauder's Map away. "

"Snape? He's at Hogwarts too?"

"He is the Head of Slytherin and Potions Master."

Sirius was obviously dismissive of this. His attitude towards Snape had not changed much even as he grew older, and it was not like Lupine had the slightest apology for what happened back then.

"Well, now is not the time to talk about these things. We should go back to the castle immediately and use the Marauder's Map to see if we can find any trace of Peter."

Lupine suggested.

Sirius looked a little hesitant. He didn't know if he could go back to the castle with Sherlock and the others.

Sherlock also obviously noticed this problem, and he took out his wand.

"You go back to your dog form first, and I'll change some things for you so that you won't be so conspicuous when you enter the castle with us."

Sirius cooperated and transformed into the black dog form again.

Sherlock tapped his wand at him, making his hair fluffy and soft, and turning his hair color into gray and white. Together with his fierce little eyes, he was like a dog. A certain variety looks exactly the same.

"This way you won't be as conspicuous as the black dog. After bringing you to the castle, we can claim to the outside world that we brought you in to make it easier to catch Black, because the dog's sense of smell is more sensitive."

Lupine praised Sherlock's excellent attention.

"Perfect! Use Black to catch Black, and no one will suspect that the dog being tracked is actually Black himself!"

With that said, they took Sirius away from the Forbidden Forest and returned to the castle.

It was just past six in the morning, and the castle was still empty. No students would get up so early.

Sherlock and the others first went to Lupine's office, then unfolded the Marauder's Map and looked for Peter's name on it.

But the three of them looked at the entire map carefully and did not see any words on Peter Pettigrew.

"Is it possible that Peter secretly found an opportunity to erase his name from the map?" Sherlock hypothesized.

Lupine and Sirius all shook their heads together.

"It's impossible. No one can erase their name from the map. Even if they wear an invisibility cloak, they will be displayed on the map."

Sherlock shrugged.

"My own name was erased by me."

Hearing what he said, Lupine and the others realized that in the office they were in now, there were only two names, Sirius Black and Remus Lupine, and Sherlock was not shown on the map!

Lupine looked at Sherlock in shock.

"how did you do it?"

"Actually, it just used two very simple little magics." Sherlock took out his wand and tapped the names of Lupine and Sirius on the Marauder's Map.

The next moment, it was as if an eraser had erased their names bit by bit, and they suddenly disappeared from the map.

"The magic you used to make this map is indeed wonderful, but the technique is a bit too old. You only need to use the unblocking spell and the elimination spell together to remove the names on the map." Sherlock explained, "At that time I discovered it by accident, and it worked after I tried it.”

The magic spells used in the method Sherlock demonstrated to them were not difficult, and any normal wizard could learn them. However, the combination of these two magic spells and their application on the Marauder's Map would never have occurred to most people. .

"Even if the names on the Marauder's Map could be eliminated, Peter is unlikely to think of this method, and he might not even know that the Marauder's Map is in Harry's hands."

Lupine guessed.

"If his name is not found in Hogwarts, it is very likely that he is hiding in the Forbidden Forest like Sirius before him."

Sherlock touched his chin and asked hesitantly.

"Then should we tell Dumbledore about this? Once he knows, it will undoubtedly be much easier to find Peter in the Forbidden Forest."

Sirius suddenly changed back from Animagus form at this time. They had agreed before that he would remain in animal form after entering the castle, but Sherlock's problem forced him to change back to human form. Have your say.

"Can't tell Dumbledore!" he said grimly.

Lupine and Sherlock looked at each other.

The two of them were inclined to report the matter to Dumbledore truthfully. With his authority in Hogwarts and his influence on the Ministry of Magic, if Peter was really hiding in the Forbidden Forest, what would he want? It will undoubtedly be much easier to find him.

"Why can't you tell Dumbledore?" Lupine asked.

Sirius's eyes shone with a light called hatred.

"If all the truth is told to Dumbledore, even if Peter is caught, he will definitely hand Peter over to the Ministry of Magic!"

Lupine frowned and looked at him: "Wouldn't that just clear your name and let Peter get the punishment he deserves?"

"Not enough!" he shouted. "If he is caught by the Ministry of Magic, the most they will do is put him in Azkaban! Those dementors are a kind of torture that is worse than life for ordinary wizards. But for wizards who have learned Animagus, they are no different from normal guards! They are only interested in human emotions, but ignore animals! This is why I have been locked up there for more than ten years! There’s no reason to go crazy yet!”

Sirius's eyes were bloodshot.

"I'm going to kill him! Kill him with my own hands!"

Sherlock sighed and waved.

"You two make a decision. This matter is mainly between the four of you. If you decide not to tell Dumbledore the truth, then I will keep it a secret for you."

Lupine looked at Sirius seriously.

"You have to think carefully. If you don't plan to hand Peter over to the Ministry of Magic in the end, then it's impossible to clear your name! The Ministry of Magic won't even give you a chance to use Veritaserum. As long as you are caught, you will definitely Let the dementors give you a kiss, and you are destined to remain anonymous for the rest of your life!"

Sirius gritted his teeth, his left cheek twitching slightly from the exertion.

"I have always thought clearly! I am guilty to begin with! Even if I am caught in the end, I will admit it! But Peter must die!"

Lupine patted Sirius on the shoulder and sighed.

"I won't let you be caught by them. Since you have already thought about it, I respect your decision."

Just when they were about to finally discuss it, Sherlock suddenly interjected.

"But I want to remind you, don't forget your godson Harry. Maybe you don't care about your future, but he needs you more."
