Wang Shen's excellent memory came in very handy at this moment. He remembered that when he first entered Song Mu's office yesterday, he glanced back at Song Mu's secretary, Song Wen. Coincidentally, Song Wen was drinking water from a glass at that time. Wang Shen glanced at the glass but hadn't paid much attention. Now, the glass next to the flowerpot did resemble the one Song Wen was holding. Apart from the color, the patterns on the two glasses seemed to match. In other words, were Song Wen's glass and the glass in front of him a couple's glass?

This counseling room was surprisingly filled with complicated male-female relationships. Wang Shen was adept at analyzing cases, but clearly not at analyzing emotional issues. However, one thing was certain: Song Mu didn't care about his secretary at all. The reason for this judgment was simple. When Wang Shen talked to Xu Wen yesterday, he had vaguely noticed the disappointment in Xu Wen's eyes when the topic of Song Mu came up. When Xu Wen mentioned that Song Mu didn't allow her to enter the counseling room without permission, the sadness in her eyes was impossible to hide. What did this mean? If a man loves a woman, how could he even forbid her from entering his own space? Furthermore, Xu Wen owned one of the couple's cups and always kept it by her side. Song Mu's cup, however, was placed next to a flowerpot. Wang Shen guessed that the cup was probably used to collect water for watering the plants.

To fall in love with someone who doesn't love you back is truly a great misfortune and tragedy. Thinking this, Wang Shen left the consultation room and went straight to the desk of his secretary, Xu Wen. Xu Wen was also at the crime scene at that moment, but was waiting outside the consultation room.

"Is there anything I can help you with?" Xu Wen looked at Wang Shen with a puzzled expression as he came out and stopped in front of her desk. Xu Wen's questions were far greater than Wang Shen had imagined. Xu Wen probably still couldn't understand why her boss's best friend had suddenly become a policeman? Why had her boss died mysteriously after meeting this friend? Yesterday, wasn't this so-called best friend supposed to have dinner with her boss? Why was the dinner canceled? What on earth had happened?

Wang Shen didn't answer Xu Wen, but simply shook his head slightly. He glanced at Xu Wen's not-so-large desk and immediately noticed the couple's mug on it. After a few seconds of silence, Wang Shen walked past Xu Wen and re-entered the consultation room.

"Have all the on-site photography and evidence collection been completed?" Wang Shen asked a young policeman next to him.

“Yes, Captain Wang, it’s all done,” the young policeman replied immediately.

"Alright, let's move this body away first and have the forensic doctor conduct a detailed autopsy. Please have them give me the autopsy report as soon as possible. Oh, and check the deceased's file again and notify his relatives." After saying that, Wang Shen turned to Song Mu again and stared at his body for a few more moments.

Suddenly, Wang Shen seemed to have discovered a new clue. He crouched down, staring intently at Song Mu's clenched fist. Wang Shen could vaguely see something between the fingers of the clenched fist. What was this? Wang Shen pondered for a moment, then waved to the person behind him.

"You, come here and pry his hands open for me, be careful," Wang Shen ordered the police behind him, pointing at Song Mu's clenched fist.

Upon hearing Wang Shen's order, the policeman immediately knelt down in front of Song Mu and used his gloved hands to pry open Song Mu's fist. Song Mu's fist was clenched so tightly that the policeman couldn't pry it open for a moment. After several minutes of persistent attempts and efforts, Song Mu's knuckles finally began to loosen.

Wang Shen gently nudged the young policeman, signaling him to stop what he was doing. "Here, give me a pair of tweezers." Wang Shen didn't turn around, his gaze fixed entirely on Song Mu's fist. A moment later, the policeman behind him handed Wang Shen a pair of tweezers. Wang Shen moved his face a little closer to Song Mu's fist. Holding the tweezers, Wang Shen's eyes widened as he carefully used them to pick up the object hidden between Song Mu's fingers.

What is this? A hair? Wang Shen straightened up, holding the tweezers in mid-air, carefully examining the hair in the light. The hair was about thirty centimeters long, seemingly from a woman. It was wavy, suggesting the owner had recently permed their hair. Looking at the hair in his hand, Wang Shen's tightly furrowed brows finally relaxed. Wang Shen always felt a sense of relief when a case was about to be solved. He guessed that the hair Song Mu had clutched tightly before her death belonged to the murderer. But as mentioned earlier, the hair belonged to a woman. If so, it created a stark contradiction with the facts. It was mentioned that Song Mu should have been incapacitated before her death. But how could a woman have rendered Song Mu incapacitated? Unless…

"Here, give me a sealed bag." Wang Shen waved to the police officer behind him. A moment later, a plastic sealed bag appeared in Wang Shen's hand. Wang Shen carefully placed the hair into the sealed bag. "Make sure this hair is preserved safe and sent for biometric analysis. I'll be comparing it with the suspect's biometrics later."

Wang Shen glanced at the computer screen again. "Has this confession been backed up?" Wang Shen asked, pointing to the document on the computer.

"Captain Wang, don't worry, we have that much common sense. Not only this confession, but we've also backed up all the documents on the computer." The young policeman said, giving Wang Shen a nonchalant smile.

"Then... what about that cup?" Wang Shen turned his gaze back to the water cup next to the flowerpot.

"Huh? You want that too?" The young policeman looked at Wang Shen with a puzzled expression.

“Of course.” Wang Shen tapped the young policeman on the head, then walked past him to the window.

Wang Shen stood by the window for a while, then looked around the counseling room again and asked, "Who discovered the body first?"

“She’s the deceased’s secretary,” the police officer beside him replied.

“Okay.” Wang Shen nodded. “Let her in. There are some things I want to ask her.”

Just as Wang Shenggang finished giving his instructions, seemingly in an instant, Song Mu's secretary, Xu Wen, appeared before him.

"Hello, we meet again." Wang Shen greeted Xu Wen very politely. "My colleague told me you were the first to discover the body?"

Xu Wen wasn't impressed by Wang Shen's sudden politeness. She simply nodded slightly at Wang Shen's question.

When did you discover the deceased?

"This morning, when I was on my way to work," Xu Wen replied softly, her head bowed.
