The group of people were very quick to move. After a while, they quickly stepped out of the castle gate and walked on the grassland on the campus. The sunset at dusk dragged their shadows very long. They walked to the willow to beat the willow. Limes skillfully picked up the broken branches on the ground, stepped into the attack range of beat the willow, and then accurately clicked the tree tumor on the trunk. The four people slid into the channel in sequence.

"Oh, I think the passage should have been designed higher at the beginning." Dumbledore bent over and smiled,

"Are you going to let everyone come in and out here every day, Professor?" Snape replied coldly,

"Don't be so serious, Severus." Dumbledore said, after a turn, they came to the end of the passage, and they stepped into the messy room one by one,

"I think you must miss this very much, Lupin." Snape said, Remus didn't reply, he pulled out his wand and walked in front,

"Where is he, Lawrence?" Dumbledore asked softly,

"Upstairs, the only room open." Lawrence also took out his wand.

"Easy, Lawrence, we are here. I think it's your turn to use the wand, and the dementors may have surrounded this place." Dumbledore said lightly, signaling Snape to pay attention to the rear. The four of them kept their formation and stepped up the stairs step by step. They came to a half-closed door. Dumbledore looked at Lawrence,

Lawrence nodded, Remus raised his wand and pushed open the door with force. The four people quickly stepped into the room, and the four lit wands pointed at the only thing in the room that made a sound - Hermione's pet Crook Hill,

"Oh," Dumblido quickly walked to the broken window that had been opened, but he didn't see anything moving in his sight. "It's obvious that he had left long ago."

"Remus searched this room, Severus went to the first floor to see it," Dunbulido said. "I'll go see the other rooms, Lawrence, you're here."

"Hey, Crook Hill." Lawrence greeted the ginger cat sitting on the bed.

"Where is that little round table, Lawrence?" Remus asked, Lawrence turned his head and saw Remus standing in front of a small stall of ashes.

"It's there..." Lawrence replied with a difficult time, "I think Black burned it?"

Remus stayed for a while, and he began to check the traces in the room with stiff movements. Not long after, Dumblido and Snape returned one after another.

"The doors and windows on the first floor are well sealed, Professor," said Snape. "No one has touched anything."

"Blake lives here," Remus said, "there is still a warmth in the bed, and he is in a hurry."

"Obviously someone informed me," Snape said, glaring at Remus, "I suggest a thorough search of his memory, Professor."

"Professor Lupin was with me before we arrived at the principal's office," Lawrence said.

"Yes, Lawrence, please take out the map and take a look," Dunbulido nodded in understanding. "Although it is unlikely, Black may return to Hogwarts through other channels."

"Okay - hey! Crook Mountain?" Lawrence had just taken out the map. Crook Mountain suddenly rushed over and snatched the map. He jumped back to the bed, called out at Lawrence, then turned to look at the map. He flexibly used his cat's palm to spread the map, and then searched for something. Everyone present looked at his actions, and a thought flashed through his mind-he could understand the map and the words above.

"I think I'm out of sight. It's a cat-climbing blood," Dunbulido's blue eyes shining, he quipped, "It might think you don't look at the map, Lawrence."

"Hulu" Crucker Mountain raised its head proudly, and it patted the map with its cat's palm. Lawrence reached out to get back the map, but was thrown by Crucker Mountain with its tail.

"Hey—" Lawrence said, Crook Mountain purred again, and then slapped the same point on the map with his cat's palm, obviously meaningful,

"What do you mean by asking me to see?" Lawrence asked, Crook Hill nodded, its tail swaying like a brush.

"Let's take a look," Dumblido also came over. Crook Mountain cooperated to move the cat's claw away. In the Glenfindo Tower, there was a small black spot in the boy's dormitory. When they saw the name clearly, everyone was stunned. Remus took a breath.

"Peter, Pet?" Snape suddenly looked up and asked in disbelief, "I thought he was dead?"

"The map will not go wrong," Remus said quickly. "James promised us confidently that we have tested many situations, and that no invisible means or transformation water can be hidden from the map."

"I know how the map is made, and I don't think there is a chance that the map will go wrong." Lawrence agreed,

"Then why is this person who should die in Glenfindo Tower?" Snape asked furiously, he poked the point on the map hard. Lawrence was afraid that he would poke the map through, "It's there!"

"Professor Lupin," Lawrence held his breath, "What is Peter's transformed animal?"

"A mouse..." Remus's voice was a little hoarse.

"There is a rat in the Weasley family...Ron took it from Percy," Lawrence said. "I think... the mouse looks ordinary, and has been in their house for thirteen years..."

"This..." Remus looked at the small dot of "Peter, a little dwarf" on the map in a daze, unable to speak,

"And it has one missing one toe on its left front toe," Lawrence said. "The last thing Peter left behind in the dwarf..."

"It's his little finger." Snape returned to his expressionless state, and after answering the words, he recognized this judgment.

"Then I think we must find Sirius as soon as possible," Dumbully said seriously, looking out the window, "Before finding him in the Ministry of Magic, otherwise the tragedy will be irreversible."

"Can you find him? Crook Hill?" Lawrence asked. Crook Hill shook her head, and its tail pointed to the vast dark cloud in the sky, which was the location of the Dementor.

"The dementors destroyed the smell." Dumbledore said, and Lawrence remembered their big hands that were rotting outside their cloaks.

"Remus, please find a way to find Sirius or send him a message. I know it's difficult, but you are the one we know most here," Dumbledore said, and Remus nodded.

"Severus, please monitor the three secret passages in the castle that Felch didn't know. If Sirius breaks in, tell him the situation and bring him to me," said Dumbledore. "Please let go of your prejudice at this time, thank you."

"I will do my best, professor," Snape replied with a narrowed eyes, "but I don't think he will trust me."

"Lawrence, I want to ask you to monitor Petr," Dunbulido ignored Snape, and continued, "This is a request, you can choose not to agree, because it shouldn't be your job."

"I can do it, professor." Lawrence replied,

"If you need help, you can find us. If necessary, I allow you to use a more powerful spell to suppress him," Dumbledore said seriously. "I will tell Professor McGonagall. I think she has absolutely professional knowledge to force Peter back to her true form."

"I have a question, professor, I've got Sirius Black from the minister," Lawrence said. "I promised Harry that if he asked, I'll tell him what I know."

"Very reckless" Snape shouted,

"You can tell Harry whether to tell you or not," Dunbulido's words made Snape swallow back again, "I mean the part that includes Peter."

"This is too rash-" Snape could only mutter from the side, saying something like "He is only fifteen years old."

"He is already sixteen, Severus." Remus reminded with a smile, and he nodded to Lawrence, "Please, Lawrence."

"I will do my best." Lawrence looked at Mount Crook, "Hey, you'll help me, right?"

Crook Mountain made a "snore" sound, he jumped from the bed, grabbed Lawrence's robe, and Lawrence picked him up,

"Let's go back." Dumblido waved his wand, and the broken wooden boards on the floor flew up, resealing the windows,

The group walked back to the room on the first floor, and they bent down through the passage. Before the entrance of the cave, Crook Mountain flexibly jumped on the tree tumor that hit the willow.

"I think we missed dinner," Dumbledore said. "I suggest we go to the kitchen to find something to eat."

"I won't need it, professor." Snape obviously didn't appreciate the idea very much, so he turned around and left, and walked towards his office in the dungeon.

"I think I'll just bring some things back to eat, I still need to prepare lessons..." Remus smiled,

"Well, I'll just bring some things back, too." Lawrence said, "I still have some reports to write."

"Oh, okay, everyone has something to do." Dumbledore shrugged, "You seem to be like the principal, I am very idle... But Lawrence, do you have any reports?"

"Actually, I have to settle some accounts with Fred and George by the way," Lawrence replied, "Because of... some questions, I haven't finished the report."

"Oh, I understand, I must be busy replying, right?" Dumbledore said kindly, carrying a basket full of food, humming a song and leaving quickly.

Author's words:

I think many people guessed Sirius could escape when they saw the appearance of Crook Mountain in the previous episode. When I wrote this paragraph, I had two choices.

One is that Lawrence will not take out the map, so that Mount Crucker will not have the chance to prompt Peter's existence. They will return without success. Mount Crucker will only give a prompt next time he has the chance. (Just kidding, I can write at least two extra chapters for this choice.)

Another type is the plot of this article. Because I thought about it later, Dunbulido would definitely not miss any opportunity, so I asked Dunbulido to instruct Lawrence to take out the map.

The first mode is to follow the plot of the original work, with a low intensity confrontation, tending to "find out the truth", and then slowly follow the original work as time goes by, but the number of words can be many, and I can also be much easier, but!
Chapter completed!
