Dumbledore sat in his chair, his brow furrowed.

The tips of his two slender fingers, habitually touching each other, rested his chin on the fingertips.

Blue eyes looked at the ceiling of the room through the half-moon-shaped lenses, as if lost in thought.

In front of him, there is a mirror, and the picture is full of shadows...... William, Hermione, and Annie, huddled together, are trying to grab the mirror.

This is a pair of two-way mirrors. When William was in his first year, Dumbledore gave Anne a Christmas present.

William deceived many times but did not come to it, and one of them was given to Dumbledore by Anne.

William: That's sour.

"Interesting corollary, Hermione." Dumbledore finally came to his senses and looked into the two-way mirror.

"So, you think Blake is an illegal Animagus who has been appearing as a black dog?"

"Professor, that's not a deduction, it's a fact." Hermione spoke firmly, confident in her own judgment.

"Yes, I trust your judgment." Dumbledore approving.

"The details that go unnoticed are not an obstacle, but a clue.

Hermione, you've been doing a great job of that.

But some more direct evidence is needed, and these details alone are not enough to convince our Minister Fudge to believe your word.

He's not as good at reasoning as you are, and he can see the truth hidden under the details. ”

"What then?" Hermione said urgently, "Unless we can catch Blake......"

"Hermione, you're ignoring someone." William reminded him, "Professor Lupin was a close friend of Blake's, so he must have known something. ”

"That's right." Dumbledore sighed, grabbed a handful of Floo powder, and threw it into the fireplace in the distance.

The emerald green flames lit up, and soon a head appeared in the flames.

"Remus, I'm sorry for delaying your recovery. But I have something that I need to ask you urgently. ”

"Please come if it's convenient, if it's not convenient...... Please give it a visit, too! ”

"Uh......" Lupin hesitated for a few seconds before replying, "Oh, okay." ”

Moments later, the fireplace swelled with a crackling sound, and Professor Lupin walked in wrapped in a tattered robe.

"What's wrong, Headmaster?" Lupin said confusedly. "What's going on?"

"Are you okay?" Dumbledore motioned for Lupin to sit down.

"It's just a little weak, Professor Snape's potion makes me have diarrhea." Professor Lupin sat down in his chair. "Other than that, everything is fine."

"I'll remind Severus."

Lupin smiled gratefully, glanced over the table, and saw the two-way mirror, and the three Williams in the mirror.

"Professor, is there anything urgent?" He asked again.

"There happen to be some. Miss Granger just told me something interesting.

She said...... Blake is an illegal Animagus.

I'd like to ask, Remus, about this...... Do you know? ”

Dumbledore's sharp eyes stared at Lupin like an eagle.

Professor Lupin's face immediately became bloodless, as if it had been coated with a layer of frost.

Needless to say, just look at the professor's face and you will know the answer.

Lupin lowered his head, as if he had made a mistake and tried to cover it up, but he was still the child who was discovered.

He clenched the handle of his chair, his fingers pale, and said in a trembling voice, "Professor Dumbledore, I'm ...... I'm sorry.

I knew about it, but I kept it a secret......"

"Remus, you shouldn't have apologized to me!" Dumbledore spoke with a hint of disappointment.

"You should apologize to Annie, William, and Hermione, the three of them, who spent a summer with a black dog.

With the exception of William, I don't think Hermione and Anne can take on a Death Eater. ”

"I'm sorry, I really didn't know this was going to happen." Lupin reproached himself.

"Why don't you say it?" Dumbledore asked calmly.

Lupin's face turned pale, and his voice was filled with self-loathing.

"For half a year, I've been struggling with myself, and I can't decide whether to speak up or not. But I still didn't say it.

Why?

Because I'm too cowardly.

Telling you means that I have failed your trust when I was a student; It means acknowledging that I've led people and people like me on night trips.

Your trust is extremely important to me.

When I was a child, you accepted me into school, and when I became an adult, I couldn't find a job everywhere just because I was ......"

Lupin paused, glancing at his glasses.

"William and Hermione have known you're werewolves for a long time, and they've been keeping your secrets for you." Dumbledore said.

Lupin looked at the two-way mirror in amazement, ashamed of himself.

"Eventually, I convinced myself that Sirius had used the magic he had learned from Lord Voldemort to get into the school.

It has nothing to do with him being an illegal Animagus......"

Dumbledore squinted his eyes and tapped his fingers on the table in a strange rhythm.

"The four of you, apart from Blake, has anyone else learned the Animagus?"

"All three of them have learned!" Lupin clutched his head and said in pain.

"They didn't distance myself when they found out I was a werewolf. Instead, it took nearly three years, and in the fifth grade, I secretly learned Animagus.

The first to learn was Jaime, who had always been gifted at Transfiguration, and even Professor McGonagall was impressed.

And then there's Blake.

Peter needed a lot of help from Blake and Jaime, and he became proficient as well. ”

"What can they become?" Anne asked curiously.

"Jaime is a stag, so he is called Pointed Fork; Blake is a ...... Big black dog, we call him Big Foot.

And Peter is a mouse, nicknamed Wormtail.

On a full moon night, it was Jaime and Black who controlled me.

Peter was small enough to easily press the scar on the Willow to allow us to enter the screaming shack through the passageway......"

Wait a minute...... Peter Pettigrew's Animagus is a mouse?

William's heartbeat accelerated suddenly, as if he had missed a beat.

He was reminded of Tom's little inner ghost in a flash of lightning.

After two incidents, the diary and the sale of Snape's women's clothes, William basically concluded that the inner ghost was by Ron's side.

I knew him well, even to the point of knowing Ron's inner thoughts.

There were very few such people, and at one point William thought that only Harry was the only one who qualified.

Now suddenly there is a new idea.

Because the spots are weird.

Crook Hill never attacks other animals, but only stares at Spotted.

When William entered the school, Spotted was Percy's pet, and now four years later, it's still alive, and after Blake escaped from prison, he began to lose energy.

Ordinary rats only live for two or three years at most.

Even Blake can become Annie's pet Black, so why can't the inner ghost be Peter?

A real rat can't be an inner ghost, but an illegal Animagus can!

When it comes to understanding Ron, and being able to control him unknowingly, who else but Spotted can easily do it?

William was also taken aback by his own thoughts.

Peter died thirteen years ago, and if it really was him, what does that mean?

Excluding the impossible, then what remains, no matter how unlikely, must be true.

William pushed the non-existent black-rimmed glasses on his face.

The new machine word digs a lot of this!

William thought for a long time, then finally raised his head and interrupted Professor Lupin.

Three minutes later,

Dumbledore grabbed another handful of Floo powder.

"Minerva, please bring Mr. Ron Weasley at once! And his rat spots! ”

Dumbledore's voice became extremely serious.

He repeatedly explained: "Remember, be careful! Spotted may be dead...... Peter Pettigrew! ”
