Hogwarts: My name is the Unforgivable Curse

"The cave is located in London, near a seaside village, the only cliff..."

Pettigrew roughly told the location of the cave slowly, and Dumbledore quietly listened to Peter's narration before nodding: "I think you can confidently say '50 to 60 percent certainty'" Remove it—you did find the location of a Horcrux."

"The place you are talking about is near the orphanage where Tom Riddle lived when he was a child. It is only natural that he would choose to hide his important Horcrux in such a nostalgic and secretive location for him."

"But according to what you said, Voldemort deployed a lot of powerful magic there to protect the Horcruxes. It may take some time to crack them, so I think we don't have to rush.

"After I place the students tomorrow, I will immediately set off to that location to investigate. But before that..."

He looked at Peter and Black with a subtle look: "You, and Sirius, what are you going to do?"

"According to you, what happened between you was a tragic misunderstanding, and it has now been resolved - but Sirius is still guilty, and you are still burdened with twelve life……"

"That's exactly what I meant to say to you, Professor."

Peter Pettigrew's eyes suddenly darkened: "I also plan to do something."

"I want to catch all the murderers who funded Voldemort, as well as his former lackeys - you are right, 'Voldemort' is not just a person, but also an idea. As long as the soil of this idea has not been burned by me Light, then James is not avenged... I can do it, professor, believe me."

"No one is better at lurking and disguising than me, and the most core Death Eaters all think that I am one of theirs, and I also know several guys who appear to be captured or missing, but are actually still alive and well. For example, Barty Crouch Jr., Fenrir Greyback... They would probably be happy to see a person who is good at lurking go to rescue their old master, and provide help and cooperate with them..."

He twitched the corner of his mouth and squeezed out a cold smile: "And when they - the accomplices who killed James are eager to jump to the surface, it will be you who eradicated the soil of pure blood wheel in one fell swoop. This opportunity will prevent them from ever getting over..."

"They have been taught by you so that they dare not move for the time being, Professor. But I can make them rampage again and bring their flaws to your hands again... This is my value."

Sirius and Lupine's eyes widened in surprise, and even Dumbledore showed a slightly surprised look.

"So, Sirius,"

Peter turned to look at Blake, who had been freed from his imprisonment and stood up at some point, his eyes softened again: "I'm sorry, I'm afraid you have to bear my sins for a while - if I don't show up in person, It will be difficult to find ironclad evidence to exonerate you. But now I still have important things to do..."

"understand."

Sirius grinned: "One person is responsible for confinement and attracting Filch, and the others are responsible for making trouble - aren't we already familiar with this routine, Wormtail?"

Peter sobbed slightly.

"Thanks, Padfoot."

He tried hard to control himself and turned his gaze back to Dumbledore, and stretched out his hand to him: "Then, let's make an oath, Professor."

"vow?"

Dumbledore raised his eyebrows in surprise: "Do you think I still doubt you, Peter?"

"You always like to do things the safest way."

Pettigrew smiled at him: "And this is probably a restriction on me - I know that I have never been a strong person. Maybe in future actions, I will be afraid, timid, and escape... I will never Give yourself permission to do that.”

"I want to be a real Gryffindor."

"..."

Dumbledore stared blankly at Peter's outstretched hand for a while, then slowly and stupidly nodded: "I understand."

He stretched out his hand towards Pettigrew, moving surprisingly slowly, as if giving him time to retreat - but in the end the two hands were still clasped together under the complicated eyes of Black and Lupin.

"Then let's get started."

Dumbledore took out the wand with his left hand and pointed it at their arms. The tip of the wand flashed with a burning light: "Peter Pettigrew."

"Are you willing to be loyal to the cause of eliminating the remaining poison left by Voldemort and eradicating the extreme pure-blood ideals, and take action and take risks for this purpose?"

"I do."

A flame shot out from the tip of the Elder Wand and wrapped around their wrists. The faint light was reflected in the eyes of Sirius and Lupine, and not a single moment was blocked by their eyelids.

"Are you willing to lurk around our common enemy, collect intelligence, pass it to me accurately and without any concealment, and follow my instructions at a moment that both you and I think is critical?"

"I do."

The second flame tightly wrapped around their wrists.

"So……"

Dumbledore's blue eyes reflected the firelight, staring straight into Peter's small mouse-like eyes: "Are you willing to come back and help Sirius Black when we all think you have completed your mission and no longer need to lurk?" Clear your name and atone for your actions in killing twelve lives?”

Peter's eyes dropped for a moment.

"professor……"

Sirius opened his mouth and stretched out his hands in confusion, wanting to do something, but he didn't know what to do. In the end, Lupine patted his shoulder and pressed his hand down - he pursed his lips tightly.

Dumbledore still held Peter's hand and looked at him quietly with his lowered, somewhat evasive eyes.

"...I do."

After a long moment of silence, Pettigrew gritted his teeth, spoke out the words at the fastest speed and in the smallest voice, and trembled violently when the third flame wrapped around his arm.

"Are you willing..." - The three of them looked at Dumbledore with a complicated expression in surprise at the same time, watching him open his mouth and continue to speak in an old and steady voice:

"Are you willing to completely abide by this unbreakable oath and will not do anything to try to get rid of it?"

"I do."

Pettigrew smiled bitterly and spoke out his answer.

The fourth flame wrapped around the two people's wrists, and then the four flames flickered for a while and then extinguished at the same time, leaving four shallow marks on the two people's arms...

"I think that's enough."

Dumbledore's fingers relaxed, causing Pettigrew to withdraw his hand. He stared blankly at him lowering his head, clenching his teeth, trying hard not to cry out - but the sobs had already left his teeth. The slit was exposed.

"You're going to Azkaban."

"……I know."

Pettigrew answered in a trembling voice.

"I'll try to help you."

Dumbledore sighed deeply: "Sirius, Peter, you stay here for the night. I will bring you to my office tomorrow to discuss... Professor Lupin, let's go back."

"I would like to stay here a little longer, Professor."

Unexpectedly, Lupine gently but firmly rejected Dumbledore: "I want to talk to them for a while."

"……All right."

Dumbledore took a deep look at the three people in the Shrieking Shack and disappeared into the darkness with a flash of fire.
