The headmaster's office was very quiet. Dumbledore was looking at the time-turner on the table, lost in thought, not knowing what he was thinking.

Kyle looked up and accidentally saw a pair of unfinished wool socks on the shelf behind Dumbledore. The socks were white, and each one had a delicate, blue "A" on it.

"Principal, do you like blue?" Kyle asked suddenly.

"I prefer purple more." Dumbledore came back to his senses and asked, "Why do you ask this suddenly?"

"Nothing, just curious." Kyle shook his head. "Professor Dumbledore, I'll leave the time converter to you. I hope you can repair it soon."

"Thank you for your trust, Kyle." Dumbledore's eyes sparkled and he suddenly became much more energetic.

"I think……"

“Boom!”

At this moment, there was a sudden heavy knock on the door. The sound was so loud that it could even be said to be banging on the door.

Kyle glanced at Dumbledore and was about to open the door when Lucius Malfoy walked in, followed by a timid house-elf wrapped in bandages.

He was the first one in all these years to break into the headmaster's office at Hogwarts.

But Dumbledore was not angry at all. He pushed his glasses on the bridge of his nose and greeted with a pleasant face.

"Good evening, Lucius."

"I'm sorry, I didn't expect your door was so flimsy." There was no apology on Lucius Malfoy's face, but rather undisguised pride.

He took out a long roll of parchment and said, "You should remember what we said before. If we can't stop the attack, you will leave.

Well... this is a temporary suspension order, and you will see that all twelve directors have signed it. We feel that you have not made full use of your talents, and poor Weasley probably always thought that you would protect him..."

"You said that, of course I haven't forgotten it."

Dumbledore smiled calmly and said, "But strangely, I have just received letters from eleven other directors. After they heard that the person who was attacked was Arthur Weasley's son, they all changed their minds and wanted to cancel their signatures on the suspension order."

Eleven letters lay on the table, and Lucius Malfoy looked paler than usual, but he was still not ready to give up.

"But you promised that if you can't solve the attack again, you will resign..." He said playfully: "Does the great Mr. Dumbledore intend to break his promise?

Of course, if you really want to, that's fine, but there may be some bad comments in the Daily Prophet tomorrow, I hope you don't mind."

Dumbledore looked a little strange.

He didn't say a word at the board meeting, so how could he agree to resign voluntarily?

But he didn't care.

"So, did you catch the murderer?" Lucius asked aggressively.

"Got it," Dumbledore said with a smile.

"Oh? Who is it?"

"It's still the same person as last time, Lucius." Dumbledore pointed to the diary on the table, "It's just that Voldemort has changed his way of doing things this time."

Lucius said nothing, his face as stiff as if covered by a mask.

"Luckily." Dumbledore stared into Malfoy's eyes and said in a calm tone, "Just ten minutes ago, Kyle...oh, this kid, he solved the incident on his own. I was just about to give him the award for his special contribution to the school."

"I have to say..." He patted Kyle's shoulder, "Including this time, you already have three awards for special contributions to the school, one a year... You are probably the best student in the history of Hogwarts."

"Thank you for the compliment, Professor." Kyle said modestly, "I am far inferior to you."

"I didn't receive so many awards for contribution to the school when I was in school."

…

The two smiled at each other, and began to praise each other's business as if no one was around. You praised me and I praised you, and the scene was so harmonious.

But there are always people who want to spoil the fun.

Malfoy glanced over with a vicious look.

Kyle was a little annoyed by his stare. He frowned and put his hands on the box, "What are you looking at?"

"Huh!" Lucius Malfoy squeezed out a strange laugh from his throat, "I have seen many geniuses, but in the end they all disappeared, leaving nothing behind. I hope you won't be like them."

In that case, don't blame him for being rude.

"Mr. Malfoy, do you know what this is?" Kyle picked up the diary and handed it over.

"Just a cheap Muggle book."

Malfoy didn't answer. "I won't touch anything so dirty."

Although he said that, a scowl still flashed across his face when he saw the damaged diary.

"I was negligent."

Kyle took a glove from the shelf next to him, put it over the diary, and then stuffed it into Lucius's hand without saying anything.

"I found this thing from Ginny's old book. If I'm not mistaken, you must have stuffed it in when you were in Flourish and Blotts."

Malfoy clenched his pale hands into fists, then unclenched them.

"Any evidence?" he said hoarsely.

"No, but that's not important." Kyle waved his hand, "What's important is that to Tom Riddle, this diary is as important as his life, because it contains his soul.

Of course, that soul no longer exists now. It disappeared completely, leaving nothing behind. "

For a moment, the diary seemed to have turned into a red-hot iron in Lucius Malfoy's eyes, and he threw it away subconsciously.

Fortunately, the house-elf following him was quick-witted and quickly reached out to catch it.

"Mr. Malfoy, it seems that you know who Tom Riddle is."

Kyle smiled and said, "Anyway, we should thank the person who took out the diary. He helped us a lot."

"That's right." Dumbledore smiled and nodded. "And he also revealed Voldemort's biggest secret. We really should thank him."

There was no trace of blood on Lucius Malfoy's face. His right hand twitched as if he wanted to take out his wand.

But he finally restrained himself, turned around, opened the door and walked out in a daze.

He didn't say a word during the whole process.

"It seems that someone is going to suffer from insomnia recently."

Dumbledore stood up and asked, "But Kyle...can you tell me how you know about Horcruxes? This ancient and evil dark magic is something that even most professors have never heard of."

His tone was calm, as if he was asking what I had for lunch today.

"During the holidays, I saw it once in an article published by Mr. Nicolas Flamel," Kyle said casually, "In the content, he denied the claim that Horcruxes belong to alchemy."

"The article of 1689?" asked Dumbledore after a moment's reflection.

He remembered that Nicolas Flamel had indeed written an article to that effect.

"Yes, there is also a supplementary note from 1691," Kyle said. "Coincidentally, the diary perfectly meets all the characteristics of a Horcrux..."

"I see." Dumbledore smiled. "I thought the four founders told you this when we were in the Chamber of Secrets... Would you like some tea? Or lemonade?"

"lemonade."

Kyle turned his head towards the window, seeming to be very interested in the gloomy sky outside. At the same time, he muttered in his heart: "If I hadn't seen that article... that's what they said."

Dumbledore did not continue the topic. He walked up to Fawkes and gently stroked the feathers of the phoenix. "You were a little impulsive just now."

"Impulsive?" Kyle asked, "You mean I shouldn't tell Lucius about the Horcrux?"

"No, it has nothing to do with this."

Dumbledore suddenly sighed, "It took me two days to knit that pair of gloves. I was going to give it to someone else."

"Uh..." Kyle was speechless for a moment, "How about I chase after him now and take it back later?"

Dumbledore thought for a moment and shook his head, "Never mind, I'd better knit another one. I should have a lot of free time after today."
