Ever since Sirius brought Harry home, the old Black house in Grimmauld Place has been filled with Harry's laughter.

Siris bought Harry Jr. a magical broom for children, and every Saturday he took Harry to Malfoy Manor to play with Draco Jr.

And Severus, after a period of decadence, gradually suppressed his increasingly strong feelings for Cynthia in his heart, and worked hard to develop an antidote.

And when it comes to Horcruxes, they've also made great progress. Dumbledore and Siris, accompanied by the Aurors Mad Eye Moody, told the story of Bellatrix who had taken him from Azkaban to Gringotts, where he retrieved a third Horcrux, the Hufflepuff Gold Cup, from her vault.

"Albus, I think there will definitely be a Horcrux in the old mansion of Gaunt, after all, it is the base of the Dark Lord, we can go there to find clues." Cynthia said, looking at the three Horcruxes on the table. "And, I think, Ravenclaw's crown should have been made into a Horcrux as well."

"The Ravenclaw crown has been gone for years, maybe we can ask the ghost of Ravenclaw, Lady Gray." Dumbledore thought for a moment and nodded.

"Then I'll go and ask her, maybe she'll know where." Cynthia stood up.

She made her way to the Ravenclaw Tower, where she saw a slender ghost looking into the distance.

"Are you Ms. Gray?" Cynthia walked up and asked softly.

The ghost looked at Cynthia in surprise, nodded, and didn't speak.

"I'm the Hogwarts Magic Circle Professor, and I want to ask you something."

"Say, if I knew, I'd tell you, Professor."

"Do you know where Ravenclaw's missing crown is?" Cynthia asked, observing the other person's expression.

The corners of Ms. Gray's mouth instantly tugged at an unnatural sneer. "I'm afraid," she said, turning to leave, "I can't help you with this, Professor." ”

"Wait! Ms. Gray! You must know its whereabouts, right? Cynthia called out to the ghost who wanted to leave.

"You're not the first to covet a crown," she said contemptuously, "and generations of students and professors have pestered me—"

"I'm not here to gain superior wisdom, I'm here for Voldemort - defeat Voldemort - aren't you interested in that?" Cynthia interrupted her.

Ms. Gray's transparent cheeks seemed to become less transparent, and she replied with excitement in her voice: "Of course—how can you say I'm not interested?" ”

"Then please tell me!"

Miss Gray's expression was not as calm as it had been. "It's—it's not—" she stammered, "my mother's crown—"

"Your mother's?" Cynthia looked at Ms. Gray in surprise.

"When I was alive," she said bluntly, "it was Helena Ravenclaw." ”

"Are you Rowena Ravenclaw's daughter? Then you know the whereabouts of the crown! Cynthia had hope in her eyes.

"Although the crown gives wisdom," Helena said, apparently trying to regain her composure, "but I suspect it won't help you defeat the self-proclaimed black—"

"Miss Ravenclaw, I'm not trying to figure it out, your mother's lost crown was most likely made into a Horcrux by Voldemort, so we need to find it! If you do, be sure to tell me the whereabouts of the tiara! ”

Helena Ravenclaw remained silent, fluttering in the air, looking down at Cynthia. She didn't speak for a long time, and just as Cynthia turned to leave in disappointment, she whispered. "I stole the crown from my mother."

"Y-what did you do?"

"I stole the tiara," Helena Ravenclaw whispered again, "and I wanted to make myself smarter and more famous than my mother." I fled with the crown. ”

Cynthia listened carefully to her and continued: "They say that my mother never admitted that the crown was missing, and she kept pretending that the crown was still there. She hid her loss from the other founders of Hogwarts, and hid my betrayal. ”

"Then my mother got sick – very sick. Even though I had done unfilial and unrighteous deeds, she still desperately wanted to see me again. She sent a man to me. The man loved me for a long time, but I rejected him. My mother knew that the man would not give up until he found me. ”

She took a deep breath and threw her head back. "He found the forest where I was hiding. When I refused to go back with him, he became angry. Barrow has always been a short-tempered man. He hated me for rejecting him, and was jealous of my freedom, so he stabbed me to death. ”

"Barrow? You mean the ghost of Slytherin——? ”

"Yes, Barro, the Bloody Man," said Miss Gray, lifting her cloak to reveal a black wound on her snow-white breast, "and when he came to his senses, he was so contrite that he took up the weapon with which he had taken my life, and committed suicide. So many centuries have passed, and he still wears shackles to repent of his sins...... He deserved it. She added indignantly.

"So...... And what about the crown? ”

"I heard Barrow stumbling towards me in the forest, so I hid it and stayed there. Hidden in a hollow tree. ”

"A hollow tree?" Cynthia asked, "What tree?" Where is it? ”

"In a forest in Albania, in a very desolate place, I thought my mother couldn't reach it."

"Albania," Cynthia repeated, clearing her mind from the chaos, "you've already told this story, haven't you?" With a student? ”

Helena closed her eyes and nodded.

"I ...... I do not know...... He...... Very likable. He seems to ...... Seems empathetic...... Compassionate......"

With that said, Voldemort retrieved the whereabouts of the missing crown from Lady Gray. He went to the faraway forest and retrieved the hidden tiara, probably not long after he left Hogwarts.

However, once the crown became his precious Horcrux, it would not remain in that tree...... No, the crown has been secretly returned to its true home, and Voldemort must have put it there!

"—the night he came to apply for a job!" Cynthia cleared her mind.

"The night he came to ask Dumbledore to let him teach, hide the crown in the castle! When he went upstairs or downstairs to Dumbledore's office, he must have hidden the crown along the way! Thank you, Miss Ravenclaw, thank you so much! ”

Cynthia turned excitedly and ran towards Dumbledore's office, leaving Helena Ravenclaw with a puzzled expression.

"Albus! There's news! Cynthia sat out of breath in the armchair in front of Dumbledore. Then he repeated his reasoning to Dumbledore from beginning to end, "So I think Voldemort hid the crown in Hogwarts!" ”

"Hogwarts ......" Dumbledore frowned and muttered. If at Hogwarts, why hasn't anyone found out for so many years? ”

"Uh...... That's what I want to say. We can look slowly, room by room, and we will always find it. Suddenly, Cynthia seemed to think of something, "I remember, when Voldemort was at Hogwarts, Salazar Slytherin's Chamber of Secrets was opened, could it be that he hid the crown in the Chamber of Secrets?" ”
