Chapter 149 Professor, How Could You...

Harry explained Sirius's origin to them, and all the Gryffindor students became interested in him.

Hermione looked up from her busy schoolwork. She looked at Sirius's hair and appearance and guessed his breed.

"This is a husky, a relatively ferocious large dog, but it seems to be larger than a normal husky."

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

This made him even forget that he was still being wanted and hunting down his enemies two days ago.

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

It was getting dark, and with the start of the Hogwarts curfew, Sirius also turned back into human form in Sherlock's office.

Sherlock was writing guessing test papers for the seventh and fifth grade students, and he asked without raising his head.

"So what do you think now?"

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

"Harry has many friends, just like me and James in the past, so he can live well even without me, but Peter-must die!"

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

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

Under the night, Sherlock, Lupin and Sirius left the castle together, and with them came Hermione's pet, the ginger cat named Crookshanks.

On the outskirts of the Forbidden Forest, Sirius touched Crookshanks' head.

"This is the smartest cat I have ever seen. It should have the blood of a catkin, and it remembers Peter's smell, which can help us a lot."

Crookshanks has a big face, and at first glance, his facial features seem to be flattened by something. It is not very beautiful, but ugly and cute.

Lupin and Sherlock were obviously people it considered trustworthy, and it had no aversion to them.

After tidying up at the edge of the forbidden forest, the two people, a dog and a cat, entered the forest again.

To find a mouse in such a large forest is basically the same as looking for a needle in a haystack. They mainly rely on Crookshanks and Sirius, who turned into a dog, to find Peter's scent.

After searching for nearly a night, they did not find nothing.

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

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

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

In order to get the news in time, Sherlock specially summoned his patronus to follow Sirius.

If there is any discovery, Sirius can let his patronus cancel himself, and Sherlock will get the news.

The final exams were getting closer.

The last Quidditch match of the year between Gryffindor and Slytherin to decide the champion also started.

Sirius and Lupin watched the game. They witnessed Harry leading the team to win the Quidditch House Cup, which Gryffindor had not won for eight years.

Sherlock had no time to watch the game because at this time, a letter from Hilke in Germany was sent to him.

It said that the Department of Mysteries of the German Ministry of Magic had made some progress in interpreting the memory of the straw man Fiddlesticks, and asked him to wait a few more days. After the results came out, she would return to Hogwarts.

The locket had been worn around Sherlock's neck for half a year. During this period, the locket, which was originally worn out and no one would pick it up if it was thrown on the ground, became newer and newer. Now it was completely invisible that it was an old thing. People would believe that it was brand new and just bought from a magic store.

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

The sound was very slight, but very rhythmic, "tick-tick-tick", just like the hands on a clock turning.

Every night when he carried the locket, he would try to take it off his neck, but he never succeeded.

Now he could only wait for news from Silk and see if he could get any useful discoveries from the straw man.

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

Because the seventh-year and fifth-year students had to take the wizard level exam held by the Ministry of Magic, Sherlock's task at the end of the semester this year was much easier. He only had to be responsible for setting exam questions for the sixth-year students.

The students he taught were all very nervous, after all, this was the most important exam in their lives.

Sherlock was very confident in them, because in the last two mock tests near the end of the semester, the fifth-year students performed surprisingly well, and overall they looked much better than the previous class.

Even George and Fred, two troublemakers who usually didn't pay much attention to their studies, performed very well in the mock exams, completely breaking Sherlock's judgment of them at the beginning of this semester.

Just after the only sixth-year student exam that Sherlock was responsible for was over, Sirius, who had been looking for Peter's trace in the Forbidden Forest, finally made an important discovery.

Lupin was still invigilating, so Sherlock had to contact Sirius and learn about the situation from him.

"Peter usually only hides in the Forbidden Forest for a week. After a week, he will run out and sneak into Hagrid's hut to steal food. He likes sweets very much, since he was in school, so even if he hides in the Forbidden Forest, he can't stand the feeling of not having sweets."

Sirius' eyes flickered, and he continued.

"Yesterday, Crookshanks found Peter escaping from Hagrid's hut. The time he steals food is basically fixed, which means that we can try to catch him this day next week!"

Sherlock thought quietly for a moment and said.

"After the exam week this week, the students will wait for another week in the castle for the results. After the results come out, this year's vacation will begin. At that time, it is still unclear what Peter's plan is, and whether he will continue to stay in the Forbidden Forest, 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 on, I will stay 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 when Harry and his third-year students took the Divination exam, Sherlock and Lupin stayed in his office together.

They opened the Marauder's Map and kept observing the situation near Hagrid's hut while chatting.

"Is it time for you to transform again?" Sherlock asked, looking at Lupin's face.

Lupin's face was pale. 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 gently.

"It should be tonight. Snape hasn't sent me the potion yet."

"He is very resentful of you. Is it just because you bullied him when you were in school?"

Lupin smiled bitterly as if he had thought of something.

"There should also be some issues with Harry's mother."

"Hmm?"

Sherlock's eyes suddenly lit up with a kind of gossip-like light.

"Is it related to Harry's mother?"

"Yes, Snape and Lily have known each other since childhood, but Lily finally chose to marry James, who was the most incompatible with Snape during their school days. He was extremely angry. He hated James and us, and he might have hated Lily too."

"Is this also the reason why he treats Harry like this?"

"Snape did transfer his hatred for James to Harry." Lupin said calmly, "But in the final analysis, he should still have memories of Lily, and such feelings may have also continued to Harry, so he hated Harry, but didn't want him to encounter any danger."

Sherlock said with a tut.

"That's really a complicated feeling."

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

"Did you hear any strange sounds?"

Sherlock looked puzzled.

"No, I didn't hear any sound."

Lupin stood up, as if he was looking for the source of the sound.

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

Before he finished speaking, Sherlock's face suddenly froze.

"Sirius canceled my Patronus Charm!"

Lupin, who was originally listening carefully to the source of the sound, was also stunned. They both looked at the direction of Hagrid's hut on the Marauder's Map on the desk. Among the names of Hagrid, Harry, Ron and Hermione, there was a prominent name - Peter Pettigrew!

Then Sherlock and Lupin had no time to worry about the source of the strange sound. They walked out of the office quickly and headed for Hagrid's hut.

At the same time, in Hagrid's hut.

Today is the execution date of Buckbeak. After Harry and the others finished the Divination class exam, they immediately put on the invisibility cloak and came here to comfort Hagrid.

But everyone was in a low mood, because they all knew that Buckbeak was not a bad magical animal, and the crime imposed on it by the Ministry of Magic was completely a slander.

Hermione was silently shedding tears, and 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 shouted with a confused look on his face.

"Scabbers! What are you doing here?"

He grabbed the screaming and struggling mouse, and Hagrid drove them out of the door with a heavy face.

"Go, go quickly! I don't want you to see the execution, and if anyone else finds out that you have left the castle without permission, 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 night.

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

Finally, when Ron was not paying attention, Scabbers finally succeeded!

He slipped out from Ron's fingers and was about to run into the Forbidden Forest in the night when a ginger cat suddenly ran past like lightning and grabbed Scabbers in its mouth.

Harry and the others saw this scene. Ron ran out from under the invisibility cloak in a panic and chased in the direction of Crookshanks' escape.

"You damn stinky cat!"

"Ron!" Hermione shouted sadly. She and Harry looked at each other and then ran away.

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

Harry and Hermione followed Ron and soon heard the sound of Ron grabbing Crookshanks.

"Stinky cat! Let it go!"

Ron took Scabbers back from Crookshanks' mouth, just as he reunited with Harry and the others and prepared to hide in the invisibility cloak to return to the castle.

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

Even when searching in the Forbidden Forest, he was still disguised by Sherlock, so Harry obviously recognized Sirius.

"It's the dog raised by Professor Forrest!"

"Get out of the way, good dog, get out of the way!" Hermione pleaded with Sirius.

But Sirius still had no intention of leaving. His eyes were no longer friendly when Harry brought him to the Gryffindor Common Room, but flashed with extremely fierce eyes.

Harry had already drawn his wand at this time, but before he could make any move, two obvious footsteps came towards them.

With a little light in the darkness, after seeing the people coming clearly, Harry and his friends immediately showed a look of joy.

"Professor Forrest (Lupin)!"

The two people who came over were Sherlock and Lupin.

However, the next scene made Harry and his friends completely stunned.

Lupin and Sherlock didn't care about their shouts, but drew their wands at them with serious faces.

At this time, Sirius also lifted his Animagus transformation, holding a wand that Sherlock had temporarily lent him, and pointed it at Harry, or more precisely, at the mouse in Ron's hand.

Harry stared blankly at Sirius's face, then at Lupin and Sherlock, with disbelief in his eyes that seemed to overflow from his eyes.

"Professor, how could you..."
