Harry explained the origin of Sirius to them, and the whole Gryffindor student became interested in him.

Hermione looked up from her busy schoolwork, looking at Sirius' hair and appearance, and guessing his breed.

"It's a husky, a big, aggressive dog, but it seems to be bigger than a normal husky."

Although Sirius was taken advantage of by Gryffindor students, he enjoyed his time.

This made him even a little forget that two days ago, he was still living the days of being wanted and chasing down his enemies.

Harry took him around the lounge, and finally brought him back to Sherlock's office.

It was getting dark, and as the curfew at Hogwarts began, Sirius reverted to a human form in Sherlock's office.

Sherlock, who was writing quizzes for seventh and fifth graders, asked without looking up.

"So what are you thinking now?"

Sirius' face became solemn, and Sherlock's question made him return to the mentality of revenge again.

"Harry has a lot of friends, just like me and James used to be, so he can live just fine without me, but Peter—must die!"

Sherlock put down the quill in his hand, and he and Sirius looked at each other.

"Since you made your own choice, I won't say much more. The search for Peter can start tonight."

By night, Sherlock, Lupin and Sirius left the castle together, along with Hermione's pet, the big **** cat named Crookshanks.

Outside the Forbidden Forest, Sirius patted Crookshanks on the head.

"This is the smartest cat I've ever seen. It should have the pedigree of a cat raccoon, and it remembers the smell of Peter, so it can help us a lot."

Crookshanks' face plate is very large, and at first glance, his facial features look like they have been squashed by something. They are not very beautiful, but they are ugly and cute.

Lupin and Sherlock were clearly the people it believed to be trustworthy, and neither of them was excluded.

After rectifying at the edge of the forbidden forest, the two, one dog and one cat, entered the forest again.

Finding a mouse in such a large forest is basically no different from looking for a needle in a haystack. They mainly rely on Crookshanks and Sirius, who turned into a dog, to search for Peter's scent.

After nearly an overnight search, they didn't come up with nothing.

Crookshanks keenly sensed Peter's scent under a tree, where Sherlock and the others found a few gray mouse hairs.

This is enough to prove that Peter is now hiding in this forbidden forest, and the direction Sherlock and the others are looking for is not wrong.

But during the daytime, Sherlock and Lupin both still have classes, so they can't accompany Sirius to search every night. The most important main force in the search for Peter is a dog and a cat.

In order to know the news in time, Sherlock specially summoned his Patronus to follow Sirius.

If anything is discovered, Sirius can let his Patronus cancel it himself, and Sherlock will get the news.

Final exams are getting closer.

Gryffindor v Slytherin is the last Quidditch match of the year to decide the championship.

Both Sirius and Lupin watched the game and watched Harry lead the team to the Quidditch House Cup, which Gryffindor had not won in eight years.

Sherlock didn't have time to watch the game because of a letter sent to him by Schilke, who was far away in Germany at this time.

The above said about the interpretation of the memory of the straw man Fiddlesticks, the Department of Mysteries of the German Ministry of Magic has already made some suggestions, let him wait a few more days, and when the results come out, she will return to Hogwarts.

The locket had been worn on Sherlock's neck for half a year. During this period, the locket that was originally worn out and thrown on the ground would not necessarily be picked up by anyone. It became more and more new. It's an old thing, and people who say it's pure new just bought it from any magic store will believe it.

And when he put the locket to his ear, Sherlock could vaguely hear a strange sound coming from it.

The sound is very slight, but very rhythmic, "da-da-da", like the hands of a clock turning.

Every night with the locket, he tried once to see if he could get it off his neck, but it never worked.

Now he can only wait for Shilk's news to see if he will get any useful findings from the straw man in the end.

After Gryffindor won the House Cup for Quidditch this year, the exam week at Hogwarts began.

The seventh and fifth graders had to take the wizarding rank exam held by the Ministry of Magic, so Sherlock's task at the end of this year was much easier, as long as he was responsible for giving the sixth grade students the exam questions.

The students he teaches are very nervous, after all, this time can be said to be the most important exam they will take in their lives.

Sherlock is very confident in them, because in the last two mock tests near the end of the semester, the grades of this year's fifth grade students were unexpectedly very good, and overall they looked much better than the previous one.

Even George and Fred usually don't pay much attention to their studies, and their scores in the mock exams are also very good, completely breaking Sherlock's judgment on them at the beginning of this semester.

Just after Sherlock's only 6th grade exam, Sirius, who has been searching for Peter's traces in the Forbidden Forest, finally made an important discovery.

Lupin was still proctoring, so only Sherlock and Sirius got in touch and learned the situation from him.

"Peter usually only hides in the Forbidden Forest for a week, and after a week he runs out of it and sneaks into Hagrid's hut to steal something to eat. He likes sweets, since he was in school, so even in the forbidden Hiding in the forest, he couldn't bear the feeling that he couldn't eat sweets."

Sirius' eyes twinkled, he continued.

"Yesterday, Crookshanks discovered that Peter had escaped from Hagrid's hut, and his time to steal food is basically fixed, which means we can try to catch him today next week!"

Sherlock said quietly for a moment.

"When the exam week is over this week, the students will wait in the castle for another week to get their grades. After the grades come out, this year's vacation will begin. What plans does Peter have at that time, and will he continue to stay in the Forbidden Forest? It’s still two words, so the time you mentioned next week is likely to be our last chance.”

Sirius obviously understood this, and his face became gloomy.

"From today onwards, I will be guarding near Hagrid's hut until Peter shows up!"

Sherlock nodded, and after letting his Patronus continue to follow Sirius, he returned to the castle.

Two days later, on the evening of the day Harry and his third-year students were taking their divination exams, Sherlock and Lupin stayed in his office together.

They opened the Marauder's map, and while chatting, they have been observing the situation near Hagrid's hut.

"Are you going to transform again?" Sherlock asked, looking at Lupin's face.

Lupin's face was pale, and every time around the full moon night, his physical condition would become very bad, and his spellcasting state would also become very bad.

Hearing Sherlock's words, Lupin nodded slightly.

"It should be tonight, and Snape hasn't brought me the potion yet."

"He is very angry with you, just because you bullied him when you were in school?"

Lupin smiled bitterly as if thinking of something.

"There should be some problems with Harry's mother."

"Um?"

Sherlock's eyes suddenly lit up with a light called gossip.

"About Harry's mother?"

"Yes, Snape and Lily have known each other since childhood, but Lily finally chose to bond with James, whom Snape did not deal with the most when he was a student. It made him extremely resentful, he hated James and us, and probably hated it too. Pass Lily."

"And that's why he treats Harry like that?"

"Snape did pass on his hatred of James to Harry." Lu Jing said quietly, "but in the end, he should still have a memory for Lily, and this emotion may have continued to Harry, So he hated Harry and didn't want him to be in any danger."

Sherlock snorted.

"That's really complicated feelings."

At this moment, Lupin frowned suddenly, his ears moved sharply.

"Have you heard any strange noises?"

Sherlock looked puzzled.

"No, I didn't hear anything."

Lupin stood up, as if searching for the source of the sound.

"It's like a clock, ticking..."

Before he could finish speaking, Sherlock's face suddenly froze.

"My Patronus Charm has been cancelled by Sirius!"

Lupin, who was listening carefully to the source of the sound, was also stunned. The two of them looked at the Marauder's Map on the desk in the direction of Hagrid's cabin. Among the names of Hagrid, Harry, Ron, and Hermione, there was an impressive There is a prominent name - Pettigrew Peter!

Then Sherlock and Lupin didn't have time to worry about the source of the strange voice, and walked out of the office together and headed to Hagrid's cabin.

Meanwhile, in Hagrid's cabin.

Today is Buckbeak's execution period. After Harry and the others finished their fortune-telling exams, they immediately put on invisibility cloaks and came here to comfort Hagrid.

But everyone's mood is low, because they all know Buckbeak isn't some bad magical beast, and that the crimes the Ministry of Magic has imposed on it is a total slur.

Hermione was crying silently. When she was about to pour the milk into the milk jug, a mouse suddenly fell out of the jug!

Ron looked at the mouse and cried out with a blank expression.

"Banban! What are you doing here?"

He grabbed the rat that was screaming and struggling, and Hagrid drove them out the door with a heavy face.

"Let's go, let's go! I don't want you to see what you looked like when you were executed. Besides, if anyone else finds out that you left the castle privately, you will definitely be punished."

Harry and the others were pushed out of the hut by Hagrid. They put on invisibility cloaks and walked towards the castle in the dark.

Banban, who was put in Ron's pocket, kept struggling. He seemed to be frightened and desperately wanted to run out of Ron's pocket!

Finally, when Ron was inattentive, Banban finally succeeded!

He slipped out of Ron's fingers, and when he was about to run along the night into the Forbidden Forest, a big **** cat suddenly flew past like lightning, and put Scabber in his mouth in one bite. inside.

Harry and the others saw this scene, and Ron ran out from under the invisibility cloak in a panic, chasing in the direction that Crookshanks fled.

"You **** stinky cat!"

"Ron!" Hermione called out sadly, and she and Harry glanced at each other, then ran with them.

The direction in which Crookshanks runs is very clear, that is, in the Forbidden Forest.

Harry and Hermione followed Ron and soon heard Ron grabbing Crookshanks.

"Stinky cat! Let it go!"

Ron took Scabbers back from Crookshanks, just as he rejoined Harry and the others, preparing to hide in the Invisibility Cloak and head back to the castle.

A huge dog stared at them with those gloomy eyes, blocking their way.

He had always had Sherlock's disguise on him even during the search in the Forbidden Forest, so Harry clearly recognized Sirius.

"It's the dog that Professor Forrest kept!"

"Get out of the way, good dog, get out of the way!" Hermione begged to Sirius.

But Sirius still had no intention of leaving, and his eyes were completely without the kindness that Harry had brought him to the Gryffindor lounge, but with extremely fierce eyes.

Harry had already drawn out his wand at this time, but before he could make any move, two distinct footsteps approached them.

With a little light in the darkness, after seeing the person coming, Harry and the others suddenly showed a look of joy.

"Professor Forrest (Lupin)!"

The two people who came over were none other than Sherlock and Lupin.

However, the next scene made Harry and the others completely stunned.

Neither Lupin nor Sherlock paid any attention to their shouts, but drew their wands at them with serious faces.

At this time, Sirius also released his Animagus transformation, holding a wand that Sherlock temporarily lent him, and pointed it at Harry, to be precise, at Ron's hand mouse.

Harry stared blankly at the face of Sirius, and then at Lupin and Sherlock, the disbelief in his eyes seemed to overflow from his sockets.

"Professor, how can you..."
