"Yes," Sirius nodded solemnly, "Peter, he must still be alive."

Sirius clenched his fists, his eyes red. Calvin had rarely seen Sirius look so angry.

"What the hell is going on, what did you find?" Even Calvin was suspicious of Sirius's remarks.

"It's not safe here, I don't know if Peter will hear me," Sirius kept looking at the ground, not knowing what he was looking for, "go to the Hog's Head Bar."

"Don't bother." Calvin pulled out a scroll, unfolded it, and brought Sirius inside.

After a moment's moment, Sirius found that the surrounding landscape had become a farm of delicate ink paintings. Look at Calvin and his own hands, it is also the style of ink painting.

"This is? Your magic?" Sirius asked incredulously.

Calvin nodded lightly and conjured two chairs for the two of them to sit down, "It's indeed my magic, it's safe here, you don't have to worry about being heard."

"Well, that's right," Sirius said eagerly, "the boy named Ron said he had lost a pet that day, and I saw that he was still sullen today, so I asked him what was going on.

He said that the mouse he had raised was missing, and that the mouse had been in his house for almost six or seven years!"

"What's wrong with that?" Calvin didn't realize for a moment that something was wrong.

"Merlin's beard," Sirius exclaimed, holding his head, "Calvin, aren't you a study of magical beasts?" Don't you think it's strange that a rat lives for six or seven years? A normal rat has a lifespan of only two years!"

"It's a bit strange—" Calvin nodded slightly, "The rats that have lived for six or seven years are about to become Nicol of the rat world... The old fairy of the rat world.

"But what does that have to do with Peter?" Calvin still didn't understand the connection between the two.

Sirius took a deep breath and tried to control his burning feelings, "I suspect that the rat is Peter, Peter Pediru."

"What?" Once again, Calvin couldn't believe his ears, "That mouse is Peter?"

"Yes," Sirius said, "Peter is an Animagus, a rat when transformed."

Calvin frowned and said, "Sirius, this statement is too whimsical, I know you blame yourself for Jaime's death, but you don't want to use this excuse to fool yourself..."

"I didn't lie to you!" Sirius roared. Then he turned into a large, thin, and thin black dog in front of Calvin.

"This!" Calvin was speechless in shock, he didn't expect Sirius to be an Animagus as well.

The big black dog turned back into Sirius again, and said solemnly, "When Lupin turned into a werewolf because of the full moon, Jaime and I and... And Pediru wanted to be by his side when he transformed, so he managed to learn Animagus."

"I'm a black dog, Jaime is a stag, and Peter is a mouse."

"Oh my God—" Calvin began to believe Sirius, "You didn't even tell me about the Animagus?"

"I was going to tell you, but Lily wouldn't let me tell you, and she was going to wait until you were in fifth grade before letting you know. But you know, in '81, it's—" Sirius waved his hand indiscriminately, "that's not the point, the point is, Peter is still alive, and we're going to catch him."

Calvin pondered for a moment and said, "If that's the case, everything makes sense."

This time it was Sirius' turn to get lost in the lake, "What's the explanation?"

Calvin pulled Sirius out of the world, "Let's go, I'll take you to Dumbledore."

Half an hour later, in the Headmaster's office, after listening to Sirius, Dumbledore crossed his hands, looked at the impatient Sirius quietly, and said with a little comfort, "It's wonderful, Sirius, but you forgot one thing, how can you be sure that the mouse is Peter?"

Sirius thundered: "Dumb

Principal Lido, why don't you believe it? Who but Peter will steal the mirror containing Voldemort's soul?"

"Ahem," Calvin cleared his throat as he sat on the couch, "Headmaster Dumbledore, it's not like there's no way to prove it."

"Remember what Peter left behind at the scene of the explosion?" Calvin stretched out a finger and said, "A little finger on his left hand, if Peter really fakes his death, then he must also be missing a finger on his left paw after the transformation. We'll just have to bring Ron over and ask."

"Ha, yes, yes," Sirius said excitedly, "I'm sure that rat must be missing a claw."

Dumbledore was silent for a moment, then summoned his Phoenix Patronus and said to it, "Mr. Wesley, please bring your brother Ron to my office after class." He wrote another note on parchment and handed it to Phoenix Fawkes.

Soon, a middle-aged wizard with greasy hair and a large hooked nose walked into the principal's office.

As soon as Snape reached the door, he stopped and stared at the Beatles, dressed in Muggle clothes and with long, messy hair.

He dragged out his tone, longer than any other time, "I said, how did I smell a rotten stench downstairs, it turned out to be a prisoner from Azkaban. Blake, have you finally come to confess your crimes to Headmaster Dumbledore?"

The corners of Sirius's mouth twitched, and he replied unceremoniously, "Shut your mouth, snot, I can almost sleep listening to you, I don't know how your students put up with you." And your hair, if you don't have the money to buy shampoo, I don't mind giving you the last bottles Jaime gave me."

"Stupid dog with no brains," Snape resisted the urge to pull out his wand and give Blake a flash of invisibility, "what's the matter with calling me over, Albus."

Dumbledore briefly told Snape about Sirius' speculation. Snape stared at Blake with a strange expression, "Are you making up a story, Blake? Still faking your death?"

Sirius was so angry that he didn't even want to use his wand, and just rolled up his sleeve to give Snape two punches.

Fortunately, Calvin grabbed him in time, "Ron will come over in a moment, and it will be clear when the time comes, ask him if the mouse is missing a finger."

"Ron Wess coming?" Snape sneered, "That boy is even more stupid than Harry Potter, I think he's a lot like Black."
