Professor of Gemology at Hogwarts

"If you must know, the potion ingredients are missing from my personal storage room...no doubt some lawless savior wants to make a forbidden potion..."

"It seems that you are quite sure who the thief is?" Gray asked.

"Isn't this something you need to be more concerned about? Maurice, do you think you are qualified to question me?" Snape said coldly, "I have enough evidence and enough reasons to expel them -"

But obviously his expulsion plan failed, otherwise he wouldn't be in such a bad mood just after coming out of the principal's office.

"So the evidence is...?"

Gray was a little curious as to what those kids were trying to do in private.

"Two red hairs appeared on the floor of my private storage room." Snape sniffed. "It's easy to think of-the arrogant Potter and his stupid Weasley. Apart from them, No one would dare to do such a thing under my nose, nor would they be stupid enough to expose themselves."

Gray watched as his wand slowly lifted up two tiny red hairs.

"If they make any trouble after making banned potions, that's another matter. Of course, I don't expect it. After all, with their ability, it is difficult to even make a simple shrinking potion. Such low abilities It just allowed them to stay at Hogwarts for two more years." Snape said viciously, "They should feel lucky for their stupidity!"

"There are many redheads, Professor Snape," said Gray.

"Yes, you are right." Snape unexpectedly confirmed his statement, "But most of them are in Gryffindor, aren't they?"

He used his wand to burn the suspended hair into ashes.

"So you don't mind if I deduct some points, do you?" Snape was a little proud and curled his lips, "I don't think it's unfair..."

"I hope you can save some 'situation' during your patrol tonight. Filch will be a good helper for you." Snape sarcastically said, "But I think nighttime is usually Gryffindor's special event."

……

The thick dark clouds that blocked the sky finally dissipated. The long-lost moonlight shone on the large stone floor in the corridor, and there were no dementors flying around. Gray, who was patrolling at night, felt very comfortable.This quiet atmosphere couldn't help but make his mind wander. What on earth was Claire thinking about during the day?Who stole Snape's medicine?Weasley?How was he going to find and capture Peter Pettigrew?

Suddenly, a cat meowed through the dark night, and the sound came from the underground level.

"What's going on!" complained a portrait next to him, "You're not letting people sleep anymore?!"

Gray turned around and climbed into the criss-crossing stairs, walking quickly in the direction of the cat's meowing, only to see Filch running over holding an oil lamp, wheezing and panting, followed by Mrs. Norris.

"Professor Morris!" Filch reported breathlessly, "There is someone on the first floor!"

"Knox..." Gray extinguished the fluorescent spell on his wand.

"This...?" Filch's eyes widened when he saw Gray extinguishing the light without saying a word, "Could it be...could it be...Black?"

"No, it won't, otherwise your cat won't come back alive." Gray joked, "We have to deal with it cautiously and successfully catch these naughty students."

"It makes sense." Filch breathed a sigh of relief, and the nervous expression on his face immediately changed to a fierce look, "Students running around in the middle of the night will definitely die if I catch them!"

In this way, Gray and Filch split into two groups. Filch started patrolling from the first floor below, and Gray started from the top floor.

The late night corridors of Hogwarts are filled with the sound of sleeping breathing, and the portraits rest peacefully with their eyes closed.The flame illuminated by the candlestick on the wall automatically became very small, leaving only a little spark. Gray stepped on the black shadow of the window frame reflected on the corridor's stone slab, and walked step by step into the night. His dark robe made him almost inseparable from the darkness. The corridors blend into one.

He will not patrol cautiously like other professors, because he knows that the so-called murderer Black will not appear here. Tonight is nothing more than patrolling diligently and catching naughty students.

But who would go out for a night out when they knew that "murderer" Blake might appear in danger?

Definitely one of them.

"Tsk!"

Pass him to the fourth floor.As I passed my office, I heard dissatisfied sounds coming from the wall.

"Good evening, Mr. Emery Switch." Gray greeted hurriedly without stopping.

"You've disturbed my sweet dream again! Where are you going?"

"I'm on patrol, Mr. Emery Switch," Gray whispered.

Gray turned around and found the one-eyed witch statue. He had just stood there for a few seconds when the one-eyed witch's hunchback was moved away and a red hair popped out of the hole.

"Filch would never think of..." The red-haired boy stopped mid-sentence and looked at Gray blankly.

"Hurry up, Fred!" An urgent voice came from the secret passage, "Let me go up first!"

"I think we're in a bit of trouble, George." Fred tilted his head.

……

Mr. Emery Switch was woken up again. When he was about to get angry, he found Gray leading two red-haired students into the office.

"Didn't expect that he really caught it?" Emery Switch muttered, "Huh, sure enough, he is a Gryffindor student at first glance!"

……

"Tell me?" Gray sat on the chair, "What are you doing outside in the middle of the night?"

The Weasley twins looked at each other.

"Prank, Professor." Fred shrugged.

"Where are you playing a prank?" Gray held on.

"Filch's little room," said George.

"We only put a little something, it won't hurt him..." Fred pinched his little finger with his thumb and made a gesture.

"We'll be in the lounge right now, professor." George cooperated.

Gray looked at the two of them.

"Take it out?" he said.

Fred took a small spray bottle from his pocket and placed it on the table.

"This is a quick-acting sneeze spray, Professor," Fred said.

"That's not it." Gray said with a serious face, "Map."

The Weasley twins looked at Gray in surprise and then at each other. Finally, Fred pulled out a large square piece of parchment from under his robes. It was very worn and had nothing on it.

"Open it," Gray said.

Seeing Gray's determined look, the Weasley twins no longer planned to quibble.

Fred pulled out his wand, tapped the parchment lightly, and said, "I solemnly swear that I am up to no good."

In an instant, thin lines of ink spread like a spider web from where the tip of George's wand touched, connecting, criss-crossing, and extending to every corner of the parchment; then words appeared on the top, green. Large floral letters:

Moonface, Wormtail, Padfoot, and Prongs

gentlemen who help magical mischief makers

Introducing

Marauder's Map

Although Gray was mentally prepared, he was still surprised when he saw the map blooming in front of his eyes. He restrained his expression, picked up the map and unfolded it, pretending to be examining the map, but in fact he had already started looking for the name. ——Peter Pettigrew.
