Professor Minerva-McGonagall glanced at the Headmaster with some suspicion, and when she saw the serious expression on the other side, she even wondered if she was deliberately playing tricks on herself.

But it was less than a quarter of an hour before one o'clock in the afternoon.

Professor McGonagall decided to wait in the Headmaster's office for a moment to see who the new Defence Against the Dark Arts professor was.

As the minutes ticked by, Jon Hart didn't seem to be in a hurry, he sat in the headmaster's chair and looked at the Daily Prophet that he hadn't finished reading in the morning.

Just as Professor McGonagall was getting impatient, there was a sound of footsteps coming down the stairs.

Professor McGonagall looked up quickly.

......

With a creak, the brass door of the principal's office was gently pushed open.

Then, I saw an old lady walking in with a cane.

She looked very old, very old, with short hair covered in hoarfrost, her face was full of wrinkles, and her teeth were almost gone......

However, unlike the appearance of aging, judging from the posture of walking, she seems to be very energetic, and the afternoon sun shines down the window and sprinkles on her silver hair, and she even looks a little "radiant".

"Merlin's beard, I hope I'm not late!" said the old lady slowly.

At the same time, she looked around very casually, and seemed to be very familiar with the environment in the principal's office.

"Are you...... Professor Melese?" Minerva-McGonagall exclaimed as she looked carefully at the old lady in front of her before she recognized her.

"I can't believe that after forty years of leaving Hogwarts, there are still people here who remember me. The old lady seemed a little surprised, and she turned and looked directly at Professor McGonagall:

"If I'm not mistaken, you're supposed to be Minerva...... The last time I saw you, you were a likable little girl, but I didn't expect you to be so old now...... It's a shame it took the Sorting Hat five minutes to get you to Gryffindor instead of my Ravenclaw......"

Listening to the other party's regretful voice, Professor McGonagall couldn't hide her surprise at all: "Professor Melles, you are actually willing to return to Hogwarts to teach...... However, your body ......"

"My old bones are indeed a little unbearable...... If I were to stay at Hogwarts for another year and a half......" Professor Galatia Meles said with a smile, "but Headmaster Hart wrote to me that I only need to go back to Hogwarts temporarily to fill the vacancy for more than a month, which I would be happy to do, and life after retirement is indeed a bit too boring. ”

Galatia Meleth was a Defence Against the Dark Arts professor at Hogwarts, and by the time she retired, she had been at Hogwarts for about fifty years...... And after more than forty years of retirement, a letter from the Headmaster of Hogwarts brought her back to the castle.

The old lady turned around again and looked at the young man sitting in the principal's chair, and she grinned and said, "I want to ...... You must be Mr. Hart...... The youngest headmaster in Hogwarts history, it seems, is exactly that. ”

"Yes, it's me, Professor Melles. Jon quickly stood up and nodded at the old professor with a smile, "Welcome back to Hogwarts." ”

......

"It's so nostalgic!" said Mrs. Galatia Meleth, looking around, "I thought I would never be able to come ......back here when I was like Albus."

Looking at the portraits on the walls, Professor Meles's gaze finally stopped.

She leaned on her cane and smiled and bowed to one of the portraits, "Principal Black, long time no see!"

"Good afternoon, Meles. Phineas Black took off his hat and saluted Professor Melles.

Galatia Meles's gaze continued to wander around the portrait wall, and finally stopped at another portrait: "And Professor Duppert, it's a pleasure to see you again!"

"Ahem, ahem, ahem, Galatea!" Armando Duppet said as he coughed a few times, "I didn't expect you to be back at Hogwarts." ”

"yes, I didn't expect my old bones to do anything more for Hogwarts. Professor Meles replied, her gaze continuing to search the portrait wall.

"Oh!" she snorted, asking suspiciously, "Headmaster Hart, why didn't I see Albus's portrait on it?"

As she spoke, she turned to look at Jon curiously with her old eyes.

"It happened suddenly, and Professor Dumbledore's portrait hasn't been finished yet. Jon replied calmly.

"Really?" the old lady's eyes flashed as she smiled slyly at Jon, "I see......"

"Professor McGonagall, is there anything else you can do?" Jon didn't bother with the old lady again, but turned to look at the Vice Principal, "I'd like to talk to Professor Mellos about the Defence Against the Dark Arts class. ”

"Then I'll take my leave!" Minerva-McGonagall didn't notice anything unusual, and she withdrew from the Headmaster's office.

......

"Sit down, Professor Meleth!" Jon waved his wand, and a chair with a pale blue cushion appeared in front of Galatia Meleth.

The old lady first set her cane aside, then sat down and stretched her muscles.

"Honestly, I'm a little sorry when I hear about Albus's death......," she said slowly, "it's a shame that a wizard as great as him left this world like this without explanation, isn't it?"

"yes......" Jon replied casually, "things are impermanent, aren't they?"

"Is there anything else you have to do with the young Headmaster who summoned me, an old lady, back to Hogwarts?" Professor Meles asked slowly, again.

"I'm afraid you guessed it. Jon didn't hide it, and said calmly, "Do you remember a student named Tom Riddle...... Attend Hogwarts before you retire from Hogwarts. ”

"Of course...... A very hardworking and smart child. Professor Meles closed his eyes, pondered for a moment, and nodded, "I am generally impressed by students like her. "Just forty years ago, after you retired, he returned to Hogwarts to apply for the position of Defence Against the Dark Arts professor you had left......" Jon continued, "but Headmaster Albus Dumbledore rejected his application because he thought he was wrong......"

“...... And after that, a curse began to spread at Hogwarts......"

“...... There's never been a Defence Against the Dark Arts professor who has been at Hogwarts for more than a year!"
