When Sherlock and Filch walked through the entrance to the Gryffindor lounge together, it was already nine o'clock.

Felch looked at the pocket watch in his hand, then lifted up a paraffin lamp to illuminate the castle corridor that had begun to become dim.

"No, they must be planning other tricks this year!"

After staying near the Gryffindor lounge for a long time, Felch couldn't help but mutter in a low voice.

It can be seen that in this confrontation between the Weasley twins, he often came out of a disadvantage and was always led by someone.

"Well, Professor Forrest, since we haven't caught the person we want to catch here, we'll go to the lounge in Slytherin to take a look, and the students aren't so honest."

He muttered, and walked in front with a paraffin lamp to lead the way for Sherlock.

Just as Felch walked to the corner of the corridor and the stairs, a strange sound suddenly rang out.

The sound was very strange, as if someone had triggered some pre-set device. The sound was small and slight, but Sherlock immediately became alert.

He subconsciously took several steps back.

And Felch was not so lucky.

The pre-set magic was triggered, and five small balls suddenly rolled out from somewhere on the walls on both sides of the corridor!

They rolled on the ground at an extremely fast speed, circled around Felch, and shrank smaller and smaller, as if they were deliberately teasing him!

The moment the ball appeared in Felch's eyes, his face instantly became frightened. At this time, he could already predict his next fate.

"No!"

Accompanied by a shrill call, the five small balls finally gathered around Felch and exploded with a bang!

"Bang!"

The explosion of five small balls was not loud, and the range of exposure was also very small, but an unbearable stench instantly filled the entire corridor!

A yellowish-brown smoke with a strong visual impact completely wrapped Felch up!

Sherlock, who had already taken several steps back, covered his nose with his cuffs and frowned and couldn't help but take a few steps back.

"How are you? Felch"

Felch did not respond to him, but the hysterical scolding had already revealed that his condition seemed not good at all.

"Damn it! Damn it! Damn it! Those two bastards! I must catch them! I will whip them with a whip! They are punished to be locked in a year in handcuffs! Let them be fired!"

The foul smell that was emitting like smoke that was gradually floating away from the cesspool, and Felch's miserable appearance also appeared.

He was covered in yellow dirty stuff on his body, his expression was frustrated, and he seemed helpless to spread his hands full of sticky objects, standing in the middle of the corridor.

Such a nauseating foul smell makes it difficult not to doubt what the yellow sticky object is.

Felch seemed to be furious, but his rich experience in dealing with such things still left him with some rationality.

"Professor Forrest, the patrol tonight is probably coming to an end. I have to go back and get these things on me clean."

He finished speaking, and couldn't wait for Sherlock to answer, so he fled from here in a hurry with a paraffin lamp.

Sherlock was helpless when he looked at his disappearing back.

Well, he had underestimated the strength of the two twins before.

Felch is no longer at a disadvantage, but is being bullied.

Today, I plan to let this castle administrator familiarize him with Hogwarts' plan to be unsuccessful.

Until now, he only knew where the Gryffindor lounge was, and still knew nothing about the rest of the castle.

Sherlock paced in front of the Gryffindor lounge door, waiting for the stench in the corridor to almost disappear before passing by, while hesitating whether to take him alone and walk around the castle alone, at least familiar with the structure.

But he was worried that he would meet Professor McGonagall or Dumbledore on the way, so he couldn't explain why he didn't sleep in the middle of the night and was wandering around the castle.

Just when Sherlock was having a headache and tangled, the entrance to the Gryffindor lounge suddenly opened quietly, and a slight sound of conversation came from it.

"He must have left. So many feces bombs exploded together, so he had to soak in the pool for at least one night."

"I guessed he would be here tonight, and he really thought we would deal with him like last year? It's ridiculous, Weasley never treats the same people with the same prank!"

"Okay, it's enough to get here. It's time for us to open the map of the living spots. The people in the lounge can no longer see us."

George and Fred carefully climbed out of the entrance. Sherlock was standing silently under the candlestick on the same wall as the entrance, and they did not notice him.

"I solemnly swore that I won't do good things!"

George pulled out his wand, chanting a spell, and knocked on the worn and disgraceful parchment in his hand.

Suddenly, a wonderful change appeared on the parchment, but from Sherlock's angle, he could not see the changes on the parchment.

"Hoho! Hogwarts' Night Tour King is back! We're back to the castle after two months, so where should we go next?"

"I think we should go to the statue of the Hunchback Witch first. There are some materials for making the dung bombs, and we still hid some there last year."

"Yes, tonight, we used up our last inventory to deal with Felch, and it's time to add it..."

"Wait Fred!"

George, who was observing the situation on the parchment, suddenly interrupted Fred.

He pointed his finger at a place on the parchment and said with a trembling voice.

"Look at this."

Fred turned his eyes to the point where George pointed.

That is the corridor in front of the entrance to the Gryffindor lounge where they are now, and their names are displayed on it.

But next to them, there was a somewhat unfamiliar name that was close to them, and even some of the letters overlapped together.

"Summer, Sherlock Forrest..."

Fred swallowed and read the name on the map of the Living Spot. At the same time, he turned his neck mechanically with George and looked at the direction marked Sherlock's name on the map.

In the shadow below the candlestick, Sherlock, who had been silently watching them using the live spot map, quietly stared at the two unlucky guys and asked calmly.
