Harry and the others looked very disappointed, and no matter how hard they tried, Ivan still refused to reveal the slightest bit of news.

Considering that there were still two or three days before the court begins, Ivan was a little worried that their idle eggs would hurt, and secretly looked for Sirius's place of detention in private, and then spoke.

"Harry, if you have this leisure, you might as well think about how you will make your statement in the courtroom when the time comes, your testimony is very important, and it may affect the final outcome of the trial!"

Under Ivan's reminder, Harry remembered this, and suddenly became a little nervous, he had never been to court, and he didn't know what to do.

"We can go to the library to find out the specific process of handling cases in the trial court, and don't we know about the major cases that have been recorded in the past 100 years?" Hermione suggested.

"Great idea!" Harry nodded.

With directions, Harry pulled Ron and Hermione to the library.

Ivan, of course, didn't follow, and casually found an excuse to say that he had something to do later, and then declined Harry's invitation.

In fact, there are so many detours in being a witness, and you don't want to be a lawyer or commit perjury, just tell the truth.

The reason why Ivan took the initiative to mention this matter was purely to find something for Harry and the others to do and distract them.

Just as he was thinking about it, Ivan suddenly sensed something, turned his head sharply, and looked out the window, the sky was gray, and there seemed to be some creature surging in the clouds.

"Dementors? Are they coming so fast? Ivan immediately remembered that Snape had told him that the Ministry of Magic was planning to send some Dementors to assist the Aurors in guarding.

Ivan had always been distrustful of such evil creatures, and it was impossible to expect the Dementors to have any self-control, so he planned to go and see what the Ministry of Magic was up to at night.

......

As night fell, dozens of strange figures in cloak floated around the top of a ruined observatory at the top of Hogwarts Castle...

By this time, Ivan had transformed into an owl, passed through the Dementors' patrol, and flew to the vent to stop.

The Dementors have almost zero eyesight, and under their special senses, they don't seem to have much interest in animals, so they don't even notice the presence of owls...

This also allows Ivan to easily see the inside of the observatory.

It looked like a small cage, with walls in disrepair pitted and creviced with moss and vines.

Sirius and Peter were tied face to face at both ends, not only with shackles on their hands, but also with their bodies tied up sturdily...

In addition to them, there was an Auror standing inside the observatory, holding several pieces of parchment in his hand, writing down something with a quill.

"Pettigrew-Peter, is there anything else you have to say? You haven't told me exactly how you were discovered..."The Auror scribbled Peter Pettigrew's confession on parchment, and then continued to ask.

"I really forgot, I don't remember anything, he used the Oblivion Charm on me and made me forget a lot of things..."Peter shook his head in a trembling voice.

"Someone used the Oblivion Charm on you? Who? Albus Dumbledore? Why would he do this to you? Is it because you know some secret information? ”

The Auror suddenly became very excited, he had been ordered to come here to find out what was going on, but it seemed that there was an unexpected reward.

He knew that Minister of Magic Fudge had been very unhappy with Dumbledore lately, and if he could find the other party's handle and report it, he might be able to gain the Minister's appreciation.

"No, it's not Dumbledore, it's Ivan Hals, that demon!" Peter replied in horror.

As soon as Peter remembered that experience, he couldn't help but feel a chill in his heart, he didn't know how much he had forgotten, and he didn't know if his memory had been modified...

"Ivan Hals?" The Aurors vaguely felt that he had heard the name, but he couldn't remember it for a moment.

Sirius, who had not spoken next to him, said suddenly. "That's a very good little wizard, and it's the same one who found Peter's trail... As for why he used the Oblivion Charm on Peter, I think it was in the process of investigating that he was worried about what Peter had done."

The Auror frowned, it was illegal to use the Oblivion Charm to delete or modify a wizard's memory.

But he didn't say much, because this time the situation was more special, the victim Peter was a criminal, and the other party also had a reason to use the Forgetting Charm, so he just recorded the incident on paper.

After repeated questioning, and making sure that Peter had said everything that needed to be said, the Auror turned to look at Blake, and said with some anticipation.

"Mr. Black, I wonder what you've thought of my suggestion?"

"You expect me to say after the verdict that I've had a good time in Azkaban? Putting in a cell is like going home? Blake said with a sneer.

"I didn't let you say that, Mr. Black... You just need to show that there is no abuse or other injustice in Azkaban..."

Auror's expression was very embarrassed, and he also understood that this was not very authentic, but this was an order given from above, and he could only try his best to negotiate, so he continued bitterly.

"If you are willing to cooperate with us, the Ministry of Magic will give you enough compensation when you get out of prison!"

"Compensation? Do you mean some gold gallons? Sirius pursed his lips disdainfully, the last thing he lacked was gold gallons, and the Ministry of Magic was counting on some gold gallons to buy him.

What's more, Sirius looked down on the Ministry of Magic's behavior in his heart, looked at the Auror with disdain, and spoke.

"Anyway, when I get to the courtroom, I'll tell you the truth!"

Seeing Sirius so stubborn, the Auror was a little unbearable, in his opinion, the Ministry of Magic had already given enough sincerity, and he even let go of his low-faced request, but the other party still didn't know how to lift up.

Thinking of this, the Auror couldn't help but threaten.

"Mr. Black! I advise you to think about it, it's not a good idea to go against the Ministry of Magic! You haven't been cleared of your name yet..."

However, Sirius didn't take this at all, he didn't pay attention to the other party, he knew very well that if it weren't for the Ministry of Magic, he wouldn't send someone to beg him to say good things and mention any compensation...
