In the bathroom, a brief silence fell into the bathroom.

Harry Evans stood there, with her back light, making it hard to see the expression on her face.

"Continue!" she said coldly.

"If I want to sneak into Hogwarts with a reasonable identity, I will inevitably choose to pretend to be a freshman." Matthew continued to speak slowly: "After all, students above the second grade have certain social interpersonal relationships. If there is a slight wrong behavior, it will easily attract the attention of others. Many times this is very fatal..."

"Among the first-year students, wizards, or semi-wizards, students from families need to contact their families frequently and also need to go home on holidays; if something is wrong with the child, parents may write to the school, which will undoubtedly be easily exposed..."

"So at first, I thought the real murderer who created a series of events was disguised as a Muggle-born student; but soon, I discovered another object that was more suitable for disguise-"

Matthew said coldly: "Harry Evans, a wanted criminal's child... His wanted criminal's mother would not write letters to Hogwarts. At the same time, even if he did not go back on Christmas or Easter holidays, her mother would not dare to come to Hogwarts to conduct 'theory', right?"

Harry Evans suddenly smiled and said, "Yes, you're right!"

"I guess you had long been eyeing the young Mr. Evans, and then attacked him before he boarded the Hogwarts Express. After all, his mother would not dare to go to Kings Cross Station to take him on the train; and then he drank the compound decoction made of his hair and became what he looked like."

“To minimize the attention of others, you create Harry Evans with an extremely introverted and unwilling to communicate with others.” Matthew continued: “But it was too deliberate, and there were too many loopholes—”

"It's like on a boat heading to the castle, Hermione took the initiative to say hello to you, but you didn't even say anything. This was really too deliberate! I had a little doubt at that time."

"At the subsequent branch ceremony, you used brain closure surgery to deceive the branch hat and let Harry Evans get the same Gryffindor Academy as his mother. Everything seemed to be going well..."

"But when you arrive at Hogwarts, you show more loopholes-"

"First of all, if you are really a person who is so timid that he dares not say anything, why should you be assigned to Gryffindor College? You must know that Gryffindor is the 'Brave' college!"

"Secondly, an extremely introverted ‘autumn child’ is wandering around the castle every day; I can't remember how many times I ran into you in a strange place in the castle a few weeks before school starts... There is no doubt that this is very abnormal. If you are really so introverted, shouldn't you be huddled in the Gryffindor public lounge all day... The character and behavior are completely inconsistent!"

"So at that time, I vaguely felt that you might be on campus and want to find something..."

"Then it was Potion class. Honestly, I was not a man who believed in the theory of blood; but Harry Evans's mother, Lily Evans, was a proud student of Horas Slughorn, and a true genius in Potion class when she was not a dark wizard! Whoever your father was, would their children be so slutty in Potion class? Honestly, I don't believe it."

"And after you burned several crucibles in a row, my doubts in this regard have deepened... How can a crucible be so easy to burn? I even tried it myself a few times, but I couldn't achieve your level... And at that time, I had a bold assumption-"

"And the subsequent theft of the storage room of Horace Slughorn further verified my original assumption!"

"At that time, you had already stolen the medicinal materials from the Slughorn storage room and began to quietly prepare compound decoctions, preparing to lurk in Hogwarts as Harry Evans for a long time. However, the small tin tin crucible used by our first-year students cannot withstand the quality of this advanced potion. If you burn it for a few days, you will leave traces on the crucible..."

"As an experienced pharmacist, Slughorn can easily discover something if he sees the traces on your cauldron, coupled with the theft of two precious medicinal materials, the snakeskin of the African tree and the horns of the bicorn in his own storage..."

"So on the one hand, you make yourself perform extremely poorly in potion classes, and on the other hand, when traces appear on the crucible, you forcefully burn it completely... In this way, even if the truth is revealed, no one will suspect you."

"After all, who would have thought that Mr. Harry Evans, who performed the worst in potion class and often burned the crucible, could prepare a compound decoction privately?"

After talking for a long time, Matthew slowed down a little before continuing to speak:

"There are so many of the above, and it's not too big a loophole... But when it appears on Harry Evans alone, the loophole is too big. So as early as Halloween Eve, when I saw you appear again in a position that shouldn't have appeared and found an extremely clumsy excuse, I can be sure that you are the culprit of all these incidents!"

"Is that..." Harry Evans blinked, his eyes full of charm and desire.

Matthew did not look her in the eyes and continued, "So, the several attacks at Hogwarts are also very easy to explain--"

"Nevil once told me that Ronald Weasley had a big fight with you before being attacked and made you cry; I think he must have been with you day and night, and discovered that you are actually a woman's secret."

"And Crabb and Goll said that Weasley had left the prize showroom before the attack; and before the attack, you, who was cleaning Principal Rozier's office with me and Neville, was ordered by Principal Rozier to send a stack of documents to Mr. Pringer's office..."

"I'm afraid I'm afraid I met you Weasley in front of Mr. Pringer's office. I was worried that he would tell you your secret, so I'll launch an attack on a whim!"

"As for Miss Adams and Mr. Carlo, when they returned to Slytherin Common Lounge from Slug Club, they might have happened to meet you who was stealing herbs in the Potions Classroom at the time... so you had to attack them."

"As for Justin Finlieri." Matthew smiled: "When Justin was in Hogsmeade, he was caught by a mysterious woman, asked something, and then cleaned his memory... That mysterious woman is probably Harry Evans' mother, Lily Evans!"

"As a wanted criminal, she could not contact Hogwarts. After not having any news about you for a long time, she had to take the risk and sneak into Hogsmeade. She was catching the first-year students in Hogsmeade, hoping to learn about you from their mouths and your personal safety... If I weren't smart at that time, I would have been almost caught and questioned by her!"

"But Lily Evans's forgetting curse is really not very good. As time goes by, Justin Finlieri seems to be thinking about what happened that day... You are worried that after Justin recalls his memory, the situation will be bad for you, but he took him away while he was in the Forbidden Forest."

"There is another interesting thing, that is, Neville Longbottom, who was in confinement with Justin, was unscathed. Judging from the attacks of Miss Adams and Mr. Carlo, the murderer did not seem to care about attacking one or two people; but Justin disappeared, Neville was intact..."

"I can think of only one reason, that is, the relationship between the attacker and Neville Longbottom is pretty good. He is unwilling to attack him until he has to..."

Matthew said for granted: "Navi is indeed a 'friend' with a great personality. If I were the attacker, I would definitely not want to hurt him!"

"Mr. Wickfield..." Harry Evans finally spoke, his voice sounded a little delicate: "You have said so much, but don't forget that the initiator of all events is a blood-sucking monster..."

"Is the blood-sucking monster?" Matthew looked indifferent:

"Perhaps, Hogwarts doesn't have a blood-sucking monster at all?"

"Or maybe, we all can be blood-sucking monsters?"
