April 20

Professor McGonagall's office contained a large number of books and other items.

On the right wall sits an old flying broom— Comet 200.

William carefully studied the history of flying brooms and remembered that this was a broom that was launched in 1940.

It wouldn't be an exaggeration to call it an antique.

This is clearly the broom that Professor McGonagall used when she was on the Gryffindor Quidditch Team.

Even now, she still keeps this broom. Next to the broom is a poster of the Montrose Magpies.

Montrose Magpies were once the most successful team in the United Kingdom - Ireland League, winning the League Cup 32 times and the Europe Cup Championship twice.

However, the team has long since fallen from grace, but Professor McGonagall still retains her teenage years' love for idols.

On the wall behind Professor McGonagall was a group photo: a slightly younger McGonagall and a male wizard whom William did not recognize.

Just as William was observing the office, a worried Professor McGonagall finally picked up a piece of parchment, wrote down a lot of information with a quill pen, sealed the envelope, and handed it to a white owl at the window.

After giving McGonagall a affectionate peck, the owl spread its wings and flew away from Hogwarts, disappearing into the sky.

Professor McGonagall rubbed her head, seemingly suffering from a headache. After sitting in her chair for a moment, she finally said, "William, I've already written to Professor Dumbledore. Even if he receives it, he has to attend tonight's trial and probably won't be back until tomorrow morning."

William immediately stopped looking around and nodded obediently.

Professor McGonagall stared at William and continued, "Child, don't tell anyone what you've learned today. It could involve the lives of three innocent people."

The three innocent people refer to Snape, Hagrid, and Robert.

William knew the gravity of the situation. He nodded and said earnestly, "Professor, I won't tell anyone. Please inform me immediately when Professor Dumbledore returns."

Professor McGonagall hesitated for a moment, glanced at the ring on William's index finger, and said, "I can't remove that ring either. I think Professor Dumbledore will have a way, so you don't need to worry too much."

William felt that McGonagall was just trying to comfort him, but he still got up to leave. Just as he was about to walk out, he suddenly turned around and asked, "Professor McGonagall, may I ask why Professor Snape was taken away? Was it simply because he was suspected of committing the crime?"

Professor McGonagall hesitated, unsure whether to tell William. After a moment, she sighed and said, "A Dark Magic wound was found on Tywin."

When the Auror used the Prior Incantato to examine the wand, he discovered that the magic emanating from Professor Snape's wand was coming from it.

No wonder... William suddenly realized.

It seems that Professor Tywin had a conflict with Snape in addition to entering the Room of Requirement.

So the question arises again: why did the two of them fight in the first place?

William turned and left, returning alone to the Ravenclaw Common Room.

Standing by the wooden door, he discovered that the Eagle-shaped bronze knocker was indeed gone, replaced by a huge hole.

The students were unaware of what had happened; they assumed the door knocker had been stolen again. The deans also ordered the Four Houses to close the doors to the common rooms and prohibit anyone from leaving. Therefore, everyone ate dinner in their respective dormitories.

Back in his dorm, William simply said he had some things to do and didn't answer anyone's questions.

Late into the night, he lay in bed, sipping his Bobocha, and carefully reflecting on the events of the day.

He held the Marauder's Map in his hand, which still did not include the names of Dumbledore and Snape.

Similarly, neither Robert nor Professor Tywin's names were mentioned.

As night deepened, William slowly fell asleep, and without warning, the ring on his index finger emitted a sapphire blue light.

In the darkness, they resemble stars.

Several people and a cat were all fast asleep, unaware that a dormitory in Ravenclaw was brightly lit.

Deep underground, in the Hogwarts underground palace, the lake rippled, and the golden compass on the shore slowly turned a full circle.

I don't know how much time passed, but everything returned to calm again, as if nothing had happened.

William woke up on time early in the morning.

He sat up, looked around, and saw that Bobocha had disappeared again, but the ring still on his finger reminded him that yesterday's events were not a farce.

William rubbed his face, stood up, quickly washed up, rolled up the Marauder's Map, put it in his pocket, and prepared to go find Cedric.

When he left the dormitory and entered the common lounge, the scene before him left him dumbfounded.

Many young wizards were gathered together enthusiastically, discussing the Quidditch final, as if the game might be replayed today.

William frowned and found Autumn in the crowd.

The girl was sitting on the sofa, fiddling with a hat that had Hufflepuff badger on it.

She picked up her wand and tried to use Transfiguration to make the little badger move, but unsurprisingly... she failed.

William sat down beside her and asked in a low voice, "Qiu, what happened? Didn't Professor Flitwick announce the cancellation of the finals?"

Autumn was suddenly startled, then with a flick of her wand, her hat flew off and hit Marietta on the head.

"The finals are canceled? Who told you that? Professor Flitwick didn't inform us."

Marietta pulled the hat over her head and laughed loudly, "William, are you still half asleep? Today's the final! How could it be canceled?"

Look, you can even see the layout of the Quidditch Pitch from here!

Following Marietta's gaze, William saw the Quidditch arena in the distance through the huge floor-to-ceiling windows of the Ravenclaw Tower.

Hagrid is carrying a microphone, preparing to place it on the stage, while Madam Hooch is checking the venue's safety equipment.

Professor McGonagall stood in front of the Gryffindor audience, wand in hand, designing a roaring lion.

Something must be wrong!

William stood there, stunned. After a long pause, he belatedly asked, "What's the date today?"

"April 20th," Qiu said.

No, yesterday was April 20th, and today should be the 21st!

William hurriedly pulled out the Marauder's Map, and after uttering the secret command, a large number of names appeared on it.

His heart was pounding so hard it felt like it was going to explode from his chest.

On the map, he saw Robert's name at the entrance to the common room; he saw Professor Tywin in his office; he saw Dumbledore; he saw Snape...

William was completely bewildered.
