"I have a question," Felix interrupted, "Why didn't I receive the alarm from the endoscope?"

The three people who were originally excited suddenly shut up, and the air was filled with unspeakable silence. After a few seconds, Harry said ashamedly, "I forgot to bring it, Professor, I changed into new clothes."

"It seems that the short-term peaceful life has made you lose your vigilance."

Felix said calmly. He didn't look angry, but Harry felt more guilty, and his face was burning.

Dumbledore looked at Harry and the other two: "So, you forgot to bring the endoscope, so you didn't find Sirius Black in advance. What happened next? Why did you identify him as an Animagus?"

Harry raised his head, "We came back from Hagrid because of Buckbeak's case..." He paused, "When we passed by the Whomping Willow, a big black dog suddenly jumped out. He, he attacked Ron and tried to take him away."

Felix saw a glimmer of doubt in Dumbledore's eyes, which happened to be what he himself was puzzled about. Wasn't Black chasing Harry? Why did he give up the opportunity that was within his grasp and attack Harry's companions?

Let Harry also experience the pain of losing his master? This doesn't make sense.

"My mind was blank at the time, and I subconsciously used the Disarming Charm. The spell hit the big black dog and knocked him out. It was at that time." Harry said with his eyes wide open: "I saw the big black dog's head flash and turned into Black's face. I have seen his wanted posters many times and I will never make a mistake."

"The big black dog rolled on the ground twice, and Hagrid suddenly ran out of the house and roared in our direction. Black turned and ran away."

Harry didn't say a word. The big black dog looked at him strangely at the time, as if he was a little angry, but also with relief... Was he dazzled? Why would he think so?

He continued: "Hagrid carried Ron to the school hospital, and then he left, saying that he would search the entire Forbidden Forest."

It sounds a bit like angry words... The Forbidden Forest is not just this small piece next to Hogwarts. The Forbidden Forest can accommodate acromantic giant spiders, centaurs, unicorns, trolls and werewolves at the same time.

In fact, Hagrid's emotions were much more exaggerated than Harry said. Looking at his furious look, he seemed to want to tear Black apart.

Dumbledore said softly, "I see." He closed his eyes and sat quietly aside. Flitwick couldn't help asking, "Felix, can your peephole detect the Animagus form?"

Felix nodded and said, "In theory, it is feasible, because I designed it to target name, bloodline and magic at the same time." He looked at Professor McGonagall hesitantly, "Of course, I am not an Animagus..."

"If that's the case..." Professor McGonagall said thoughtfully, "It can indeed be found that Animagus transformation is not the same as ordinary animal transformation. Wizards retain magical abilities and human thinking abilities." "

And it's not clear what form Black was in when he tried to sneak into the castle last time. If it was Animagus, it would explain the problem, Albus."

Dumbledore agreed, "My opinion is the same as yours, Minerva. The question I just thought about was why Black kept staring at Mr. Weasley," he looked at Ron, "Is there any special reason?"

Ron said uneasily, "I, I don't know, sir. I have nothing on me..." He looked down at himself and suddenly realized, "Scabbers is gone!"

"Is it your pet mouse?"

"Yes, it was here just now. It might have been scared and hid itself."

Felix glanced at Ron, he drew out his wand and quickly shouted: "Scabbers, come here!" However, there was no response, "It's not nearby."

Black's inexplicable obsession with Ron, the sudden discovery of the Animagus, and if Ron was fine, then what would be the problem...

He looked at Dumbledore and said in a deep voice: "Headmaster, things may not be what we think."

Dumbledore did not make a judgment easily: "There is someone who can tell us the answer... Minerva, is Remus still in his office?"

"Always here. He won't have a good time these days." Professor McGonagall said vaguely.

Hermione said in a sharp voice: "Principal Dumbledore? Do you know that Professor Lupin is, is a..."

"Yes, I know." Dumbledore said, his tone implying that this was the end. "Remus has been in the office these days, dealing with some old problems, and he has no energy to pay attention to other things. But I need to talk to him in depth. He may provide some information that we don't know."

Dumbledore stood up, his eyes fell from his high nose bridge to Harry, "For the next period of time, I hope you stay in the castle and don't go out. Carry a snipping mirror with you."

The professors left, Harry, Ron and Hermione looked at each other, and were about to speak, but Madam Pomfrey came in. She re-applied a layer of white ointment on Ron's wound, which made Ron grimace in pain, but soon, he felt less painful, and the wound was itchy.

"This child needs time to recover. You should not stay too long." Madam Pomfrey warned. She pursed her lips and said sternly, "Why do you always make yourself so embarrassed?"

Harry said gloomily, "I want to know the answer to this question too."

When there were only three of them left in the ward, the room was quiet, with only Ron's intermittent breathing. His wounds were painful and itchy, and it seemed that the whole repair process was accelerated by more than ten times.

Hermione suddenly said, "Harry, have you ever thought that Black's target has never been you?"

Harry wanted to open his mouth to refute, but he couldn't speak. He also felt that this was possible, which made him a little embarrassed and annoyed, as if his long-term preparations were a joke.

But what does this have to do with Ron?

Hermione dug out the beaded bag and took out the chestnut memory disk from it. "We can try to piece together our memories and combine what we have seen."

After a moment

, "Look here, isn't it obvious enough? Black's target is very clear, that is Ron, but Ron... it shouldn't be ~ when Black was locked up, he was still a baby."

Hermione said very entangledly, "Does anyone in your family have a grudge against Black?"

"It is also possible that his brain was damaged by the Dementors." Ron said sullenly.

"Remember the information we overheard at the Three Broomsticks? Minister Fudge said that Black spoke very logically and asked him for newspapers. This doesn't seem like something a madman would do."

"What does this mean? Isn't there a rumor that the mysterious man has secretly contacted the Dementors? Those cloaked monsters may have let him go for the sake of his master."

"Ron, use your brain, it's going to rust." Hermione said angrily.

Harry thought of the key point, "Newspaper, you mean, he saw the newspaper... and escaped from prison a few days later. The key is the newspaper, Ron, remember the letter you wrote to me during the holiday? There was a clipping of your family winning the annual award of the Daily Prophet."

Ron showed a surprised expression, "So Black saw the news that our family won the award, and suddenly became jealous and crazy, and ran over to kill me? God, a total of only 700 Galleons! And it's almost all spent..."

Then he said with disgust: "Why does Fudge carry a newspaper with him? His brain is Bastard. Was Kebik crushed?"

Hermione said, "It can't be this reason, Harry. I still don't understand it now, but we have to find the newspapers of the time to see if there is any missing information."

Harry added, "And Professor Lupin, I bet he must know something, just look at Dumbledore's attitude."

Hermione looked a little hesitant, "Oh, Harry, I think it would be better for us to visit him in a few days after the professors confirm that there is no problem..."

On the other side, Felix separated from Dumbledore halfway, and Dumbledore didn't want anyone to disturb his conversation with Lupin.

But for Felix, some clues were already in front of him, and he only needed to re-sort the information at hand and find out the most likely guesses.
