Just a Defense Against the Dark Arts Professor

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

Hermione looked up from her busy studies. 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 this time very much.

This made him even forget that two days ago he was living a life of being wanted and hunting down his enemies.

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

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

Sherlock was writing guessing papers for seventh- and fifth-grade students, and he asked without looking up.

"So what do you think now?"

Sirius' face became serious, and Sherlock's question made him return to his revengeful mentality again.

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

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

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

Under the night, Sherlock, Lupine and Sirius left the castle together, and with them was Hermione's pet, the big 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 catnive, and it remembers Peter's smell, so it can be of great help to us."

Crookshanks' face is very big, and at first glance it looks like his facial features have been squashed by something. He is not very beautiful, but he is cute and cute.

Lupine and Sherlock were obviously people it believed it could trust, and it had no objections to them.

After tidying up at the edge of the Forbidden Forest, the two of them, one dog and one cat, entered the forest again.

Finding a mouse in such a large forest is basically no different from finding a needle in a haystack. What they mainly rely on is Crookshanks and Sirius, who has turned into a dog, to detect Peter's scent.

After nearly a night of searching, they found nothing.

Crookshanks keenly detected 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 the forbidden forest, and Sherlock and the others are not wrong in the direction they are looking for.

But Sherlock and Lupine both had classes during the day, so they couldn't accompany Sirius to search every night. The most important main force in searching for Peter was a dog and a cat.

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

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

Final exams are getting closer.

The last Quidditch match of the year between Gryffindor and Slytherin to determine the championship also started.

Sirius and Lupine both watched the game. They witnessed Harry leading the team to win the Quidditch Academy Cup championship that Gryffindor had not won for eight years.

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

It said above that the Department of Mysteries of the German Ministry of Magic has some clues about interpreting the memory of the straw man Fiddlesticks, and asked him to wait for a few more days. After the results come out, she will return to Hogwarts.

The locket has been worn on Sherlock's neck for half a year. During this period, the old locket, which was once worn and thrown on the ground and no one would pick it up, became more and more new, and now it is completely invisible. It is an ancient thing, and some people will believe it if they say it is brand new and just bought it from any magic shop.

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

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

Every night while wearing the locket, he tried once to see if he could take it off his neck, but he never succeeded.

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

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

Since the seventh- and fifth-grade students have to take the Wizarding Level Examination held by the Ministry of Magic, Sherlock's task at the final stage this year is much easier. He only needs to be responsible for setting exam questions for the sixth-grade students.

The students he taught were very nervous. After all, this could be said to be the most important exam they would take in their lives.

Sherlock was quite confident in them, because in the last two mock tests near the end of the term, the results of this year's fifth grade students were unexpectedly excellent, and overall they looked much better than the previous one.

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

Just after the sixth-grade student exam that Sherlock was responsible for ended, Sirius, who had been searching for Peter's traces in the Forbidden Forest, finally made an important discovery.

Lupine was still proctoring the exam, so only Sherlock and Sirius contacted him and learned 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 to Hagrid's hut to steal food. He likes sweets very much and has done so since he was in school, so even if he is in the Forbidden Forest, he will hide in the Forbidden Forest for a week. Hiding in the forest, he couldn't bear the feeling of not being able to eat sweets."

Sirius' eyes twinkled as he continued.

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

Sherlock thought quietly for a moment and said.

"When the exam week ends this week, the students will wait another week in the castle for the results to come out. After the results come out, this year's vacation will begin. What plans does Peter have at that time? Will he continue to stay in the Forbidden Forest? Or two, so the time you mentioned next week will most likely be our last chance.”

Sirius obviously understood this, and his expression turned gloomy.

"From today on, I will always be standing guard near Hagrid's hut, waiting until Peter appears!"

Sherlock nodded and asked his Patronus to continue following Sirius before returning to the castle.

Two days later, on the evening when Harry and his third-year students were taking the Divination exam, Sherlock and Lupine 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 Lupine's face.

Lupine had a pale face. Every time around a full moon night, his physical condition would become very bad, and his spellcasting state would also become very poor.

Hearing Sherlock's words, Lupine nodded slightly.

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

"He has a lot of resentment towards you. Is it just because you bullied him when you were in school?"

Lu Ping seemed to have thought of something and a bitter smile appeared on his face.

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

"Um?"

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

"Something to do with Harry's mother?"

"Yes, Snape and Lily have known each other since they were children, but Lily finally chose to marry James, whom Snape couldn't deal with the most when they were students. This made him extremely angry. He hated James and us, and probably also hated him. Let’s go to Lily.”

"Is this why he has such an attitude towards Harry?"

"Snape did transfer his hatred of James to Harry." Lu Ting said quietly, "But in the final analysis, he should still miss Lily, and this emotion may also extend to Harry. So he hates Harry, but he doesn't want him to be in any danger."

Sherlock said with a tut.

"It's really a complicated emotion."

At this moment, Lu Ping suddenly frowned and his ears moved keenly.

"Did you hear any strange noises?"

Sherlock looked confused.

"No, I didn't hear anything."

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

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

Before he finished speaking, Sherlock's expression suddenly became startled.

"Sirius canceled my Patronus Charm!"

Lupine, 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 hut. Among the names of Hagrid, Harry, Ron and Hermione, clearly There is a conspicuous name - Peter Pettigrew!

Then Sherlock and Lupine had no time to dwell on the source of the strange sound, and walked out of the office quickly together, heading to Hagrid's cabin.

Meanwhile, in Hagrid's cabin.

Today is Buckbeak's execution day. After Harry and the others took the Divination exam, they immediately put on their invisibility cloaks and came here to comfort Hagrid.

But everyone's mood was low, because they all knew that Buckbeak was not a bad magical creature, and the crime imposed on him by the Ministry of Magic was a complete slur.

Hermione was crying silently and was about to pour the milk into the milk jug when a mouse suddenly fell out of the jug!

Ron looked at the mouse and shouted with a confused look on his face.

"Banban! What are you doing here?"

He grabbed the rat that kept screaming and struggling. At this time, Hagrid also drove them out the door with a serious look on his face.

"Let's go, let's go! I don't want you to see the execution, not to mention that if anyone else finds you leaving the castle privately, you will definitely be punished."

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

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 not paying attention, Banban finally succeeded!

He slipped out from Ron's fingers, and was about to rush into the Forbidden Forest along the night, when a big ginger cat suddenly flew past like lightning, and caught Scabbers in its mouth in one bite. inside.

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

"You damn stinky cat!"

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

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

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

"Smelly cat! Let it go!"

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

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

Even during the search in the Forbidden Forest he had Sherlock's disguise on him, so Harry obviously recognized Sirius.

"It's Professor Forrester's dog!"

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

But Sirius still had no intention of leaving at all. His eyes completely lost the kindness that Harry had brought him to the Gryffindor common room, but instead shone with extremely fierce eyes.

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

With the help of a glimmer of light in the darkness, Harry and the others immediately showed expressions of joy after seeing the person clearly.

"Professor Forrest (Lupin)!"

The two people walking over turned out to be Sherlock and Lupine.

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

Neither Lupine nor Sherlock paid attention to their shouts, but pointed at them with serious expressions and drew out their wands.

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

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

"Professor, how could you..."
