"What about that secretary, Xu Wen? Does she love Song Mu?" Wang Shen asked, looking at Xu Xiaolin's angry face.

"That silly woman must really love Song Mu. I heard she fell for him back in college." Xu Xiaolin put down her coffee cup and composed herself.

"University? They knew each other back in university?" Wang Shen was somewhat surprised by this information.

"That's right, they're alumni. To be precise, that woman should be Song Mu's junior, I think she's a year younger than him. That woman pursued Song Mu back in college, but unfortunately, she never managed to win him over. I never expected that after graduation, she would become Song Mu's secretary. She's really a persistent woman."

"Why are you telling me all this?" Wang Shen fiddled with his phone for a moment, then put it back in its original place.

"Because of that woman, I think it's very likely that she's the murderer who killed Song Mu." Xu Xiaolin said this in an eerily calm tone. Xu Xiaolin showed neither a mysterious speculation nor any hint of panic.

"Why did you come to this conclusion?" Wang Shen observed Xu Xiaolin's expression for a while, ruling out the possibility that Xu Xiaolin was just making things up.

"There's no reason why, it's just a feeling. I've been to Song Mu's psychological clinic a few times, and I've seen that woman a few times too. Every time I see her, I can see the hostility and hatred in her eyes. You should trust a woman's intuition. However, it's also possible that she mistook me for my sister."

"Even if that secretary treats you like your sister, why would she hate your sister?"

After Wang Shen asked the question, Xu Xiaolin's gaze lingered on his face. "Officer Wang, I really should advise you not to work so hard. Spend some time dating someone, experience what jealousy is like. That woman's behavior is what you call love turned to hate."

"It seems you really dislike her."

"I wouldn't say I absolutely hate her. It's just that I don't really like her. Okay, I have an event later, so I have to go." With that, Xu Xiaolin picked up her bag and stood up from her chair. "By the way, my accusations against her just now might have been influenced by my personal feelings, so please don't take them to heart." Xu Xiaolin smiled at Wang Shen and left the coffee shop.

Although Xu Xiaolin only provided some insignificant information, it deepened Wang Shen's suspicions about Xu Wen. Initially, Wang Shen's motive for suspecting Xu Wen was a crime of passion. But what would be the purpose of a crime of passion? Was it just because Song Mu had liked Han Mo? But Han Mo was already dead. Would Xu Wen be so foolish as to kill her beloved for a dead rival? Just as Wang Shen was pondering these questions, his phone received a text message: "Captain Wang, the autopsy results and some evidence identification results are in."

Wang Shen rushed back to the police station and convened an analysis meeting regarding Song Mu's case. All the police officers present at the scene of Song Mu's murder were present, including the forensic pathologist and colleagues from the analysis department.

"Alright, everyone's here, let's begin. First, Dr. Li, please present the autopsy results of the deceased."

After Wang Shen finished speaking, he saw a middle-aged man stand up from his chair and walk to the projection screen. Several photos of the deceased appeared on the screen. One of the photos featured a close-up of the face. "The autopsy revealed that the deceased died between midnight and 1 a.m. The cause of death was an overdose of sleeping pills. Furthermore, no wounds were found on the body. However, trace amounts of the drug were found in the blood. Aside from that, no further findings were discovered."

After analyzing the autopsy results, Wang Shen nodded to the forensic doctor, who then sat back down in his chair. "Gentlemen, you are welcome to share your opinions on this case," Wang Shen said, looking at the police officers present.

About a minute later, a young policeman glanced at the people around him, cleared his throat, and said, "Let me start by sharing my opinion. When I saw the confession the deceased left on the computer, I initially believed it was suicide. However, based on the current autopsy results, homicide is more likely." After the young policeman finished speaking, all eyes were on his face. Everyone fell silent, and the young policeman became somewhat nervous. He wasn't sure if his judgment was accurate, and he was even more afraid of embarrassing himself in front of his seniors. But he calmly adjusted his breathing and still stated his assessment. "Dr. Li just mentioned that trace amounts of a sedative were detected on the deceased. Why would someone commit suicide use a sedative? Sedatives would render a person incapacitated, making suicide even more impossible. Based on this clue, I deduce that the murderer likely administered a sedative to the deceased, rendering them incapacitated, and then forced a large amount of sleeping pills into their mouth, causing death. This method seems plausible. However, there's one thing I still don't understand: the confession on the computer. I can't determine its authenticity, but regardless, the murderer must have known the deceased very well. Otherwise, they wouldn't have written such a confession. Of course, it's more reasonable to consider the confession as a suicide note. The murderer's purpose was likely to make us believe that the deceased chose suicide because they lost faith in life. However, a handwritten suicide note would be more convincing. I think the reason it wasn't handwritten is because the murderer knew they couldn't forge the deceased's handwriting in a short time."

"Isn't it possible that the confession was written by the deceased himself?" The younger officer had barely finished speaking when an older officer asked.

“Of course, that’s a possibility,” Wang Shen interrupted the two policemen’s conversation. “But it doesn’t quite make sense. It’s also possible that the deceased was already prepared to commit suicide, in which case the murderer would have gone to unnecessary trouble.” Wang Shen also stood up from his chair and walked to the projection screen.

Wang Shen tapped the projection screen a few times, and several photos of Song Mu's desk appeared. "Everyone, take a look at these things on Song Mu's desk." Wang Shen pointed to the office supplies and water cup on Song Mu's desk with a laser pointer. "Can anyone see anything wrong with the arrangement of these things?" Wang Shen glanced at everyone present and saw that they were all frowning as they looked at the pictures on the projection screen.

The young policeman raised his hand. Wang Shen glanced at the young policeman, waved his hand, and smiled: "Xiao Liang, just say what you want to say."

"The placement of these things is strange." The young policeman stood up from his chair. "Normal people should keep office stationery on their right-hand side, like water cups."
