The Detective Agency Has Gained Another Member / The Enemy Hiding in the Shadows Is Powerful

"Huh? Huh!!"

With the blow of the brick, Greengrass's ghost seemed to feel extreme pain. He did not regain his senses; instead, he continued to bar his teeth and claws at Harry, roaring with bloodshot eyes.

"Hey, one time isn't enough, huh? Then let's try again!"

Another brick struck, and Greengrass's eyes rolled back; he fainted on the spot.

Harry, who was taking action, was experiencing an overwhelming sense of pleasure.

To be honest, as a seasoned teaching assistant and a third-year student, it had been a long time since he had been able to criticize so freely.

Moreover, his target this time is an indestructible ghost, and he has the perfectly legitimate reason of 'exorcising' to brazenly shoot it to death~

"Oh no... Dad has fainted? What are we going to do..." Astoria Greengrass muttered worriedly in a low voice.

"I'll wake him up again, just give him a little sharp stimulation." As he spoke, Harry pulled out the Wind Dagger and slashed Greengrass's thigh.

Pfft~

Greengrass's ghostly body trembled violently, then his eyes suddenly widened.

"Hmph..."

"See, he's awake now, I... hey?"

Harry paused for a moment when he picked up the brick again.

What I just did was exactly the same method I used when 'fixing' computers in my past life, wasn't it?

Don't panic if your computer freezes. Just give the case a firm tap and then restart it.

It seems the human brain is actually quite similar to a computer. No wonder the Spirit of Rowena said this method could break mind control; it does seem quite scientific after all.

So... if the computer still doesn't work after restarting, just pat it again.

"I'll hit you!"

For the third blow, Harry didn't choose Greengrass Ghost's skull again. Instead, he swung his arm and slammed it into the back of the ghost's head, causing him to stagger.

"Ah!!" This time, the ghost of Greengrass suddenly let out a scream that only a normal human could make, and even showed a look of sudden realization, "This pain... there's no mistake! You..."

But before he could finish speaking, a gust of wind blew, causing another sharp pain in the back of his head. He then rolled his eyes and fainted.

"Harry... he seemed to have recovered just now, why did you pat him again?" Hermione asked, speechless, looking at Harry who was beaming with glee.

"Uh... his stance was so cool, I couldn't help but swing it!" Harry, recovering from his excitement, scratched his head sheepishly.

"Waaah, Daddy..."

Meanwhile, the little girl from the Greengrass Family was on the verge of tears, heartbroken.

Chapter 391 The Detective Society Has Gained Another Member

Finally, Greengrass's ghost awoke.

Although the process was full of twists and turns, the ending... well, the ending wasn't exactly happy either.

"I remember now... it was you, wasn't it? You bastard, you ambushed me in that haunted Girls' Bathroom! You degenerate Half-blood- blood, Harry Potter, I'll haunt you even as a ghost!!"

The ghost, regaining its senses, didn't immediately care where it was, nor did it pay attention to its worried little daughter. Instead, it immediately set its sights on the murder weapon in Harry's hand.

I vividly remember that pain. I was in that restroom, chasing Harry Potter was breaking school rules, when that Mudblood ghost blocked my way, and then I got hit on the back of the head like that!

The pain was so intense that it pierced to the bone... Greengrass even felt as if his head had been Transfiguration and he lost consciousness on the spot.

There's no mistake, the one who plotted against me behind my back that day was definitely this bastard in front of me!

"Greengrass, can't you watch your position when you say that?" Harry looked speechlessly at the hot-tempered Pure-blood ghost. "You're already a ghost by now."

"I, um..."

Looking down at himself, the Ghost of Greengrass seemed to suddenly understand something, and his expression instantly turned utterly dejected.

"Yes, I'm dead, and I've been dead for over a year..."

"It was your daughter who commissioned us to conduct the investigation, which is why we were finally able to help you break free from her control," Harry said calmly. "Greengrass, you should thank your daughter. If she hadn't been worrying about you, her father, even while she was having nightmares, you might have continued to be controlled in that dazed state."

"Lia..." Upon hearing this, the ghost gave Astoria Greengrass a deep look, and a clear sense of guilt appeared on his face.

He can now recall almost everything that happened after he was controlled. He never expected that it would be his youngest daughter, who was usually the least liked, who ultimately helped him escape that misfortune.

"Miss Greengrass, we've completed your request. You must have a lot to say to your father, so we won't bother you any longer." Harry looked at Astoria Greengrass earnestly and said, "However, I have one request... Your father is also a suspect I need to interrogate, so I forbid you from untying his ropes!!"

"I know, thank you so much, and thank you all!"

Astoria Greengrass bowed deeply to Harry and the others in gratitude, and Harry thoughtfully gave her and her father some alone time before leading his friends out of the classroom.

"Harry ...aren't you worried that leaving that father and daughter alone in the room will cause her to let that ghost go?" Hermione asked quietly as they entered the hallway.

Her question also drew the attention of everyone present, especially Will, who seemed quite nervous.

"It's alright, if I can catch him once, I can catch him a second time." Harry shook his head nonchalantly. "Besides... if the Greengrass Family's youngest daughter really lets him go, then I'll just say I misjudged him."

Harry felt that Astoria Greengrass wouldn't do something so foolish as to drag her entire family down with her for the sake of a dead ghost.

Of course, nothing is absolute. If the other party really does that, Harry can only feel sorry for Will... although he doesn't know why he should feel sorry for him.

"Ghost... Come to think of it, he was probably the only victim last year." Colin seemed somewhat wistful. "I was really lucky back then. If I hadn't been carrying a camera with me, I'd probably be in the same situation as him."

"So the culprit who did that absolutely must be punished, no matter the cost!" Harry said coldly. "But more importantly, we need to find the guy who's manipulating the ghosts behind it all!"

Greengrass's ghost has now regained its senses, and Harry hopes that it will be sensible enough to cooperate and tell him everything honestly.

Otherwise...

"I'm sorry to have kept you all waiting. I've already talked to my father." At this moment, Astoria Greengrass, with red-rimmed eyes, opened the door.

"Granger, Dad said he'd like to speak with you alone." Astoria Greengrass nodded slightly to Harry. "Also... I'm really grateful for your help."

"Miss Greengrass, you've thanked me far too many times since we accepted the commission." Harry shook his head calmly. "And I've said from the beginning that I'm doing this for myself as well."

After saying this, Harry instructed the others to stay with Astoria Greengrass and went into the classroom alone.

"Astoria Greengrass ..." Will hesitated for a moment while waiting for Harry to speak, but finally couldn't help asking, "You and your father, you..."

"Dad apologized to me..."

With just these one sentence, tears welled up in the little girl's eyes again, but those tears did not represent sadness, but rather joy and relief.

Unlike typical second-child families, Astoria Greengrass was not favored at home.

Her personality was very different from her family's, and she was often ill. Her father, mother, and even her sister were all very strict with her, and sometimes they even felt that her birth was a burden.

Even so, she still loved her family very much, and because her illness had caused them a lot of trouble, she always felt guilty towards them.

At first, she thought that even though her father had become a ghost, he still wouldn't let her go, because he must hate her, his good-for-nothing daughter, to the core.

Unexpectedly, after so many things, her father sincerely apologized to her.

He sincerely reflected on his behavior, saying he shouldn't have been so harsh on her just because she hadn't met his family's expectations; he even said he deeply regretted trusting a treacherous scoundrel and forever losing the opportunity to spend time with his family...

"Anyway, it's all over now." Looking at the tearful girl beside him, Will didn't know what to say to comfort her, so he could only silently hand her a tissue.

"Will, I... I have a request." After sobbing silently for a while, Astoria Greengrass asked softly, "Could you please ask Granger for me? I want to join everyone and become a member of the Detective Society."

"You want to join the Detective Society?" Will was taken aback.

"Yes!" Astoria Greengrass nodded firmly. "After spending this time with you all, I feel that you are all really good people, so... I really want to become true friends with you all. Of course... I know my abilities are limited, and my background is rather awkward, but I really want to continue being with you all."

"No problem." Before Will could answer, Luna Lovegood replied softly, "At least I have no objections."

"Indeed, if it were you, I would agree too." Hermione nodded approvingly. "And that way, including Tonks who isn't here, we'll have all four Houses' members in the Detective Society!"

"Really? Thank you!" the little girl exclaimed with delight.

After getting to know them for a while, Astoria Greengrass was quite familiar with the Detective Society. She knew that if Hermione and Luna Lovegood nodded at the same time, it meant that Harry would definitely agree as well.

"Then congratulations in advance on joining, Astoria Greengrass ~" Will also showed a relieved smile and congratulated Astoria Greengrass in a low voice.

"Hmm, that's a good idea. And if she joins, can we change our identities?" Colin's eyes suddenly lit up as if he'd thought of something. "Haha, at least I won't be a commoner again this time, right?"

Will: "I think it's unlikely."

Hermione: "That's pretty tough!"

"Hey, you two!" Colin yelled at the two guys who were making sarcastic remarks.

However, to his surprise, Luna Lovegood's words were even more offensive.

"Dream."

"No... why?!"

In the corridor, everyone was laughing and chatting, except for Colin, who was bitterly protesting against his fate.

"Hehe~" Seeing this, Astoria Greengrass immediately burst into laughter through her tears.

It looks like my new life is going to be really interesting!

Chapter 392 The enemy lurking in the shadows is very powerful.

"You've come."

Meanwhile, in the Detective Society's office, the Ghost of Greengrass, bound hand and foot, sighed softly at Harry.

"Sigh, thinking about it now, it's all quite poignant..."

"Just say what you have to say, I don't have time for your sentimental talk~" But Harry wasn't buying it at all. "Who was controlling you before, spying on me and the people around me at Hogwarts? What kind of conspiracy was that?!"

"I knew it! You really are a nasty little brat!" Greengrass's ghost glared at Harry angrily. "Is this how you beg? This is practically interrogation! Get me untied right now!"

"Are you going to talk or not?" Seeing that this guy still dared to dawdle with him, Harry directly raised the brick and dagger in his hand.

Simply?

This is practically interrogation!

"How can you be like this? You're a well-known figure, how can you have no manners or politeness at all?" Seeing the weapon in Harry's hand, Greengrass was clearly still shaken and immediately started muttering softly.

However, he didn't last long in this process. He was soon driven by fear and confessed everything. "I don't know who was controlling me. After I became a ghost, I was really scared. I was also very worried about the situation at home, so I decided to follow... follow Lucius. But not long after, I mysteriously lost consciousness."

When Lucius Malfoy was mentioned, his voice seemed to suddenly become hoarse, but he quickly regained his composure and continued, "When I woke up again, my vision was blurry, and I had no idea where I was. I just had a voice in my ear that kept telling me... to stay by your side and monitor you. So for the next year, I secretly followed you to many places, including Azkaban..."

"Azkaban? So... you were there when I went to see my godfather?" Harry's expression changed upon hearing this.

"That's right, and I reported back to him word for word afterward," Greengrass's ghost nodded.

"So that's how it is! I finally understand!"

Harry glared at the ghost resentfully; he now felt that those four bricks had been too light.

He had been pondering what secrets of his had been leaked until Greengrass mentioned Azkaban, at which point it dawned on him... his leaked secret was Peter Pettigrew's finger!

Greengrass's ghost overheard his conversation with Sirius in Azkaban and relayed the information verbatim to the person behind him. After deducing that he was going to find the finger to exonerate Sirius, the person went ahead and blew the finger to pieces!

Harry is now certain that the mastermind behind controlling Greengrass's mind is the same person who turned Peter Pettigrew's mother into Inferi and left a large number of Inferi in West Highgate Cemetery!

And this guy is definitely not going to deal with Peter Pettigrew; it's 100% him!

Harry initially thought that what happened in Highgate Village was done by a Death Eater as revenge against Peter Pettigrew.

But after he learned about the Death Eater's generally neurotic style, he changed his mind.

If the Death Eater were acting out of spite, their revenge should have been more drastic. It's illogical that after blowing up the finger, the box containing it would remain intact.

Furthermore, turning Peter Pettigrew's mother into Inferi was actually too mild an act... Grinding her to ashes would be the blunder a proper Death Eater should commit.

The mastermind's actions seemed more like setting up a trap to ambush whoever opened Peter Pettigrew's mother's grave. But the question is... how could Peter Pettigrew himself have gone to dig up the grave?

Therefore, the Inferi in that cemetery, and the fingers that were blown off, were all used to deal with themselves!
