Hogwarts, this professor is too stable.

"What did you come to see me for?"

Only then did Mochir notice that Tonks didn't even change the color of her hair today. The Tonks he saw yesterday was like this, with light yellow hair that was as scrawled as withered grass, plus increasingly heavier black hair. There are circles under her eyes and her face is getting paler. This girl has been really busy lately.

But to be honest, Mochir also knew about the tasks that Moody assigned Tonks. He didn't feel like verifying who the five little wizards present that night had come into contact with in the nearly two months since they came to school. What happened? What kind of results can this kind of investigation method of finding a needle in a haystack achieve? To put it bluntly, this is all nonsense.

The child was so tired that he didn't even know to ask me if I wanted a cup of coffee. When Moqier was doing monitoring and testing just now, he saw Unique Caffe on the table.

If you don't want to drink it, then drink it. Seeing that Tonks was busy for two days and one night and came back to make up for the payment, Mochir decided not to fill the other party's house with the strong smell of coffee. He said with a straight face. He said seriously: "I came to you to exchange information."

Upon hearing this, Tonks no longer felt sleepy, and her eyes even lit up.

Like a cat whose tail had been stepped on, she almost instinctively jumped up from the bed and grabbed Moqil's shoulder. "You mean, do you have any new information?"

Mochir nodded, "In Muggle criminal behavior geography and criminal behavior psychology, there is a very effective paradigm for solving crimes, called crime close-up. I will write you a logical report now. You can do it at any time, any time. You can interrupt my logic and put forward your own point of view, even if you are deliberately seeking trouble."

He found a random notebook on the table and began to carefully sort out what had happened in the past two months.

[1] Based on the on-site investigation and analysis of unicorns and thestrals in the Forbidden Forest, as well as reports from Hagrid about other animals being similarly harmed by thestrals, it is deduced that → the perpetrator’s goal was the blood of unicorns, and this was a Very powerful enemy.

Derivation: First of all, we might as well call the person we need to find a criminal suspect. So:

1 Based on the fatal injuries of Tia (the little unicorn who was killed), it can be judged that the direct crime tool used by the suspect in the Forbidden Forest was a sharp weapon, such as a dagger, or a similar magic spell.

2 Based on the obvious restraint marks on Dia’s feet, it can be judged that the suspect has external assistance, which may be a rope that can move by itself, a bandage, or something else.

3Based on the small and healed wounds on the neck of Huahua (the Thestral cub), as well as some remaining grinding powder of wolfsbane aconite (Cavendish test, no further confirmation), it is judged that the suspect used similar sticky scars on Huahua A healing magic potion (a powerful potion made from wolfsbane aconite and white thorns), and added with barbiturates (specifically used to relieve magical beast encephalitis, tetanus, and strychnine poisoning). (causing convulsions), this drug was rare at Hogwarts, at least Madam Pomfrey said it was not stocked in the infirmary.

Based on this, it can be judged that the suspect has high attainments in potions and magical biology, and he may even be a professional magical animal doctor.

4 According to the inspection of wound marks, the suspect successively cut the necks of unicorns, giant monsters, thestrals, acrosantulas, and rune snakes. However, except for the two unicorns that were killed and had all their blood sucked, None of the other magical animals were missing. It was judged that the suspect's target was the blood of unicorns, not the blood of other animals, but the suspect himself seemed to have just figured this out.

After writing down his previous conjectures and some supporting clues, Mochier saw that Tonks was silent and reminded him, "So, do you have any doubts about these?"

Tonks frowned. Even if she didn't know about Shen Feng Wu Ying, she instinctively thought of Professor Snape based on her knowledge of potions and the blood of unicorns. However, as a law enforcement officer, she remembered Moody. The professor had told her that when handling a case, you should not stick to some intuitive experiences. You need to do multiple arguments before you can make a hypothesis.

So, if the murderer is not Snape, what should be asked?

The idea suddenly became clear, "I have no doubts at the moment, but I have some additions." Tonks frowned tightly and said, "If...I mean if, there is someone who can easily obtain the blood of a unicorn." , then he doesn’t seem to have to rush to find the blood of other magical animals as a substitute, and he still shows his eagerness to conduct multiple experiments in a very short period of time. This shows that the suspect has a very urgent need for unicorn blood. And this demand is not a long-term addiction like opium, but a short-term demand that suddenly appeared in these two months. Does this mean that the suspect only appeared in Hogwart this semester? He is a newbie in tz, and he has the abilities in the argument including knowledge of potions and magical animals, as well as tracking, combat experience, and physical fitness that you missed. Then, the probability that the suspect is a first-year freshman is very small. , we can focus on the new people joining Hogwarts."

As she said that, Tonks felt that the logic was getting smoother and smoother. She took the notebook from Moqil's hand and continued to write:

[2] The suspect may be a newcomer who joined Hogwarts this year, but there is a high probability that he is not a first-year freshman. This year’s non-freshman new faces are: 1 Mozier Cavendish; 2 Nymphadora Tang 3 Alastor Moody.

"What's this mess?" Moqier took the notebook back from her hand and quickly crossed out the two lines she had just written.

Good guy, this person’s reasoning makes even himself doubtful, even Mouri Kogoro couldn’t help but play like this while he was sleeping!

And why should I, Professor Cavendish, a Ravenclaw nerd, weak academic, and Muggle Studies professor be ranked first?

"Although your reasoning makes some sense, if it were in a Muggle police station, it might be true, but you have to understand that this is the world of wizards. Although we use Muggle paradigms, we need to use wizard thinking , I agree with what you said about focusing on the new people who join Hogwarts, but you are a natural disguisemagus yourself. Have you ever thought that someone would use this kind of magic to sneak into Hogwarts? "Well, in addition to magic, there are also potions. With just a cup of Polyjuice Potion, the Dark Lord can transform into Harry Potter, so this is not true."

Tonks was a little discouraged and couldn't help but blush. She realized that she really didn't take these other factors into consideration just now. This was too inappropriate.

"The suspect doesn't need us to guess. Just take a look at this..." As he said that, Mochir pointed the wand at his head, pulled out a silver memory thread from it, and put it into Tonks' brain. While doing this, he also explained, "This is what I saw in Ron Weasley's memory."

Memory is short, maybe only a minute or two.

The memory is presented from a first-person perspective. Ron was the first person to push open the door to the room with the three-headed dog.

The room was not completely dark, there were at least six lantern-like eyes illuminating a small area.

What could be seen on the floor was a broken recorder.

But the next moment, the recorder quickly expanded as if it had been enchanted, and several big furry feet emerged from the black shadow.

The next moment, the last frame of Ron's memory stayed on the floor and a dull crash, and Mochir connected Tonks to Jack's memory.

Those spider-like legs retracted and turned into a cloaked monster that exuded bursts of stench—a dementor!

……

"That can't be..."

"It's just what you thought, Tonks, it's a Boggart."

(Note: Boggart is a magical creature in the magical world. It is a shape-changing creature that can see into your heart and become the thing you fear most. The spell to deal with Boggart is the Boggart Expelling Curse "Funny" ", the spell makes the boggart turn into the funniest thing you think. The more people there are, the easier it is to deal with the boggart, because it doesn't know what to change. What really kills the boggart is laughter. You make loud noises Laughing, the boggart explodes into thousands of plumes of smoke and disappears.)

Tonks asked in confusion: "But... why is there a Boggart there? Shouldn't such weak magical creatures hide in abandoned classrooms or in the cubicles at the end of the toilets?"

Moqier thought for a while and decided to share the last piece of information.

"Look at this again..."

Projectors (not movie projectors, just projectors) are coming, mobile power supplies are coming, plugboards are coming, curtains are coming...

Mochier calmly assembled the equipment, and finally inserted a small magnetic card into it, which was the picture he edited from his own surveillance.

Tonks was stunned. Her father was a Muggle-born wizard, so she was no stranger to the Muggle world. But here, in Hufflepuff's dormitory, she was still surprised to see a device similar to a movie projection. She felt very inconsistent.

The scene behind the curtain began. If it was based on the scene in Ron's memory, there should be light here, but it was indeed dark at the moment.

Immediately afterwards, a black object was thrown into the middle of the room from behind the door. The six eyes of the three-headed dog opened at the same time. The black unknown object turned into the broken recorder in Ron's picture. The dog's huge body trembled, and he wanted to retreat in fear.

Soon, the door was pushed open...

Mochir rewinds the video again to where the black object started flying out, and pauses.

"Did you see it?" he asked aloud.

Tonks looked at the curtain carefully for a long time and said with some uncertainty: "It flew over from behind the door."

Mochir nodded, applauding Tonks's nonsense. He didn't show off, but pointed at the lower left corner of the curtain with a red light pen, "Did you see these two palms? Someone came from The Boggart was thrown in front of the three-headed dog behind the door, and this small hand could only belong to a lower grade student."

The wolf's tail is exposed here!

Tonks looked carefully at the position of the red dot on the curtain, but to be honest, she only saw the Boggart, which was darker than the night. As for what palm, where was it? Didn't see it.

But she didn't dare to say it because she was afraid that Mochir would ask her if she was blind...

Since Moqil said there is, then there is. If there is the palm of a junior student here, then my previous inference does contain the omission mentioned by Moqil, and there is evidence that this omission is fatal. In order to To ease her embarrassment, Tonks followed Mochier's words and said, "This also means... when Ron pushed open the door, the person who threw the Boggart was hiding behind the door. behind!"

Mochir nodded and asked: "Then why do you think he threw a Boggart at a three-headed dog?"

Tonks was right, but since none of the little wizards found what was behind the door, this clue was of little use. On the contrary, it was another point. The appearance of the Boggart was very interesting.

Tonks lowered her head to think, and soon, her eyes widened in shock, "He wants to figure out how to deal with the three-headed dog. The person who hurt the unicorn is in the castle. He not only wants the unicorn's blood, Do you want the magic stone in the secret room?!"

Mochir: So all the teachers know the Philosopher's Stone is in the Chamber of Secrets?

"Yes, it is indeed a good idea to use fear to deal with the three-headed dog. Or, to put it another way, the opposite of fear is love. Of course, you can also use love to deal with the three-headed dog. For example, if it is afraid of a broken recorder, it may like to listen to it. It’s not necessarily the same as the previous song?”

Tonks quickly covered Moqil's mouth, "Stop talking, be careful not to let others hear."

Mochir: Now you know why I installed the soundproof magic barrier?

"Sake your vow, Nymphadora Tonks!"

Moqil's sudden seriousness made the atmosphere in the room more solemn. Tonks also recovered her thoughts from the previous conversation. She rolled her eyes at Moqil angrily, "Don't swear, I will Tell Dumbledore this, and he will specifically state that it is all your credit, and your efforts will not be buried."

what?

For a moment, Mochier was so shocked that he couldn't speak.

After a long time, he finally recovered from the pain and said angrily: "Originally, I just wanted you to make an unbreakable vow, but now it seems that you are not a tight-lipped person.

Tonks, we must sign a blood pact. You cannot let others know that I have any connection with the things you are investigating. Not anyone, not now, not in the future. "

With that said, Mochier was obviously well prepared. He skillfully took out the silver-white pendant from his pocket, which already contained a drop of his blood.

Tonks looked at Mochiel in shock. She was about to become an Auror, and she didn't even know what a magical covenant like a blood pact was!

"You don't need to know what this is, you just need to agree to sign this agreement and promise not to disclose anything related to me to anyone!"

Mochir was like a wolf grandma seducing a little girl. Tonks already knew too much about him, including Legilimency, surveillance, alchemy, and getting involved in the Dark Lord's affairs... Maybe there will be more in the future!

If she told this, the sky might fall for Mochier.

He didn't want to use the Imperius Curse or the Oblivion Curse on her. For Aurors, being hit by soul magic like the Imperius Curse or the Oblivion Curse was a black history. If it was suddenly discovered during a certain inspection, it would even Caught as a spy for the dark wizard.

Therefore, a solid and unshakable covenant is essential!
