HP's Lost and the Lighthouse

For some reason, the normally perceptive Potions Master didn't notice this eyebrow-eye lawsuit that happened right under his nose.However, seeing Lupine leave, he secretly breathed a sigh of relief—this immediately made Professor Sprout even more distressed.

It can't be blamed that Professor Sprout prefers Snape who has been with him for more than ten years.In any case, Lupine was a very dangerous werewolf after all, and it would be better for him to avoid crowded places on a full moon night.

But even Snape didn't expect that even though Lupine was taken away by Professor McGonagall, something happened at Hogwarts that night.

It wasn't about Lupine, who he'd been worrying about all afternoon, but about Sirius Black, a fugitive he didn't even consider, breaking into the rock-solid place in Snape's mind. Hogwarts.

Everyone didn't understand how Blake broke into Hogwarts, which was surrounded by dementors and protected by ancient magic handed down.Nevertheless, under Dumbledore's command, the professors quickly took the students back to the auditorium where the Halloween banquet had just been held, and there was still a hint of the smell of food.

Without time to make more arrangements, Dumbledore explained the current situation to the students as briefly as possible, settled their accommodation for tonight, and hurried out of the auditorium with the professors, closing the door behind them.

"Albus," Professor McGonagall seemed a little confused, she frowned tightly, "I don't understand...how did he break in?"

Hearing that, Snape couldn't help but took a step forward.He seemed about to say something, but swallowed it after glancing at Dumbledore.

Dumbledore, who closed the door with his back to them, couldn't see Snape's small movements. He turned his head and glanced at his deputy who had been relying on him for many years, with the same serious expression: "I don't know, Minerva. It's important now The only thing is to find him, at least we must make sure he is not in the castle."

Without too much conversation, the professors dispersed immediately and went to look for Sirius Black separately.

To most professors, Sirius Black was just a fugitive from Azkaban who would pose a threat to their students, but to Snape it was more than that.

——In Snape's heart, if he, the Death Eater who conveyed the prophecy to the Dark Lord, should bear half of the responsibility for Lily's death, then Black, who leaked the location of Potter's house, should bear the other half Responsibility, not to mention the old grievances from when I was young.At this moment, old and new grudges surged into his heart at the same time. If anyone wanted to catch Black the most, it was definitely Snape.

With this thought in mind, Snape's movements became extraordinarily fast.He strode through the moving corridors of Hogwarts, scanning the empty classrooms warily, detection spells being swung uninterruptedly from the tip of his wand, the other professors only patrolling By the time he finished a section of the corridor, the waves of his robe had already rolled away.

However, even though Snape's presence greatly accelerated the patrolling speed of the professors, it was already early morning when the huge Hogwarts was searched.

Dumbledore asked the older professors who came to report to go back to their bedrooms to rest first, and pushed open the door of the auditorium by himself.

This unexpected situation obviously made the students extremely excited. It was already late at night, but Dumbledore still heard a lot of low whispers.His previously tense and stern eyebrows could not help softening for these naive and immature children who didn't know the worry and pain. Just as if he didn't hear the students' whispers chatting, he walked through the crowd carefully to find Percy.

The president of the Boys' Student Union was berating the students who were talking in a low voice. When he saw Dumbledore coming, he immediately turned around: "Sir, do you have any clues about him?"

Dumbledore had a smile on the corner of his mouth at this time: "No. Is everything okay here?" He also asked in a low voice.

The chairman of the boys' student union from Gryffindor immediately puffed up his chest: "Everything is normal, sir." Dumbledore did not miss the flash of expectation in the other party's eyes, which made him unable to hold back the corners of his lips. .

"Very good." He praised, and sure enough, he saw Percy's cheeks flush with excitement in the dim light, "There is no need to alarm them now, I have found a temporary guard for the Gryffindor portrait hole, tomorrow morning You can let them move back."

They exchanged a few more whispers, and the door of the auditorium was pushed open again.

The familiar footsteps made Dumbledore not look back.

"Headmaster?" Snape approached. "The entire fourth floor has been searched. He's not there. Filch has also checked the cellar, and he's not there either."

"Where's the Astronomy Tower? Where's Professor Trelawney's room? Where's the Owl Shack?"

"I've searched them all."

"Very well, Severus. I didn't expect Black to linger here, either," he said quietly.

Snape's fingers hanging by his side moved. He didn't look up at Dumbledore this time, but asked in a low voice, "Have you ever wondered how he got in, Professor?"

Dumbledore didn't seem surprised by the question, his blue eyes still brighter than others' in the starlight from the Great Hall ceiling.At this moment, he was staring at Snape's forehead: "There are many ideas, Severus, and all of them are equally untenable." There was a faint warning in his voice, but Snape didn't aware.

"Do you remember that conversation we had, Headmaster, just - er - just before school started?"

"Remember, Severus." Dumbledore's tone cooled down, and the warning in his tone became more obvious.

Snape paid no attention to this, and continued: "Blake's breaking into the school without relying on internal assistance - it seems - impossible. I have expressed my concern, when you specify -"

"I don't believe anyone in this castle can help Black break in." The old man interrupted Snape, and his tone made it clear that he didn't want to continue the topic.

There was a moment of silence among the three.

"I have to go down and find the dementors," Dumbledore said again. "I told them to notify them when we're done searching."

"Didn't they come to help, sir?" said Percy.

"Oh, yes," said Dumbledore coldly, with disgust palpable, "but as long as I am the headmaster, I am afraid that no dementor will cross the threshold of this castle."
