Qi Ying entered the room and said, "I heard what happened. How's mother-in-law? And what about Noel?"
Mu Feng hugged her. "Uncle Lu said that she would be fine after waking up. And Noel, the operation ended and he is in the ICU right now. Have you visited sister Lan?"
Qi Ying replied, "No, elder brother instructed everyone not to enter his chamber without his permission." She paused before saying, "I didn't tell anyone, so others don't know about the incident. Should I tell grandfather and grandmother?"
Mu Feng halted when he heard that his big brother didn't allow anyone to enter his chamber. However, since Mu Lan was mentally unstable, it was normal for Mu Liang not to let other disturb her. He replied, "Don't tell others. Have you seen the psychiatrist big brother brought?"
"Oh, yes, he came with elder brother and went to the chamber. He didn't leave yet." Qi Ying continued, "However, elder brother is in the study room. Do you think that it is alright to let the psychiatrist stay with Xiao Lan alone in the chamber?"
Mu Feng didn't share his opinion about this, even though he found it weird. He patted her shoulder and said, "Stay with mother. I'm going to meet big brother."
"Alright." Qi Ying nodded and sat on the sofa.
Mu Feng directly went to Mu Liang's study room. He knocked the door and entered the room. "I heard that you left sister Lan Lan alone with a man."
Mu Liang looked up. He ignored what his younger brother told him. He solemnly said, "This is bad. The culprit is dead. Someone killed her in the dungeon."
Mu Feng halted on his step. "What are you talking about?"
Mu Liang explained in details, "When your men found the culprit behind the scene, we immediately went to her room. To think that she worked for us for so many years… There was no evidence left in her room. There was no trace of her anywhere. I made them look all over the castle and then found her dead body in the cellar. The killer was professional. She was tortured before death. Also, there is no lead of the killer."
Mu Feng stood in front of his big brother. "What about the surveillance cameras?"
Mu Liang sighed. "Trampled. My team is recovering the date. In the meantime, they are collecting her info."
"If the dead culprit was working for us so long, I wonder how much the enemy know about us." Mu Feng clenched his fists.
"She was working for us more than twenty years. She practically knew everything." Mu Liang said.
The knocks on the door interrupted their conversation.
Mu Liang commanded, "Come in."
The person who entered the room was Zero, the acting Head Butler. "First young master, I've found the information about the maid." He came forward and gave the documents to Mu Feng who reached out his hand.
Zero continued, "Her name is Diana Muller. Everyone calls her Dia. She wasn't recruited by Noel or the previous Head Butler. She was taken by Madam Mu Lin."
"You are meaning to say that grandmother recruited her without checking her background…" Mu Feng was reading the documents and hearing what Zero was saying. "Are you sure of it?"
Zero resolutely replied, "I checked it four times and I've made no mistake about it. Madam Mu hid her domcuments in the study room where no one knew. I just got it. Dia was neither close nor unfriendly towards Madam Mu Lin. However, she despised Madam Jing Sheng and tortured her multiple times in secret. Madam Jing Sheng's personal maid said so. When Madam Mu Lin was locked up in the dungeon, one butler saw Dia going there frequently to serve food, though it wasn't her job. It could be said that she was close to Madam Mu Lin but they didn't have close connection in front of others for some reason."
"That's why when sister-in-law captured grandmother's maids back then, she wasn't included. No one knew that Dia was her close attendant." Mu Liang concluded.
"That's how it seems. Clever move for a maid." Mu Feng commented. Then he gazed at Zero and asked, "Is there anything else?"
Zero shook his head. "No, second young master."
"Okay, you can leave." Mu Feng instructed. After Zero left, he glanced at his big brother. "I don't want to think that grandmother has anything to do with this."
Mu Liang's eyes were sharp when he gazed at his younger brother. "If Dia can take your position in disguise to give your team a commend, she isn't just a simple maid. And I believe grandmother knew it and hid her documents elsewhere."
Mu Feng pointed, "Could it be she hired a secret agent?"
"Do you honestly believe that?" Mu Liang asked. "If she is, there is another one living with us, the one who killed her."
It didn't make sense. Why would Mu Lin do that? She already had the power to control the Mu Family. She didn't need a secret agent for anything when Mu Liang and Mu Feng trained people. According to the rules, she could only hire their manpower.
Mu Feng mulled over it. "…Not really when Dia took my power to harm mother. I still think that there is something amiss."
"Me too…" Mu Liang agreed. "But we need to capture grandmother first. I guess, locking her up wasn't enough punishment."
Mu Feng tapped the table with his nails. "I believe grandmother is being looked after by four of my people. I don't think she had the time to make a move. If there was anything suspicious, Ying would have told me since she was in charge."
"I can't take risk." Mu Liang got up from his seat. "Moreover, the killer is still walking around in this castle. Let's go."
