"I remember you told me that Dr. Song usually forbids you from entering his counseling room, right?" In the interval between Wang Shen and Xu Wen's conversation, the small notebook and pen that made records appeared in his hand again. After Wang Shen said this, he looked up at Xu Wen.

"Yes." Xu Wen and Wang Shen glanced at each other.

This is the second time Wang Shen has seen Xu Wen's eyes, and the first time was when Xu Wen replied to the same thing yesterday. A person's eyes are the most deceiving, and in addition to helplessness, Xu Wen's eyes also showed a little bit of fierce light......

Could the murderer of Song Mu be the woman in front of him? In fact, when Wang Shen found the couple cup next to the flower pot, he had this question. Xu Wen should attach great importance to this cup, so she will use it as a water cup at hand. And Song Mu obviously didn't care about this cup, so he put it next to the flower pot and used it as a tool for watering the flowers. Based on Wang Shen's usual experience in handling cases, love killing is indeed a good motive. However, judging from the clues currently available, it is not easy to make a judgment.

"Since Dr. Song doesn't allow you to enter his office without permission. So, how did you open the door this morning? Wang Shen continued to look at Xu Wen with doubts in his eyes.

Xu Wen took her eyes off Wang Shen's face, glanced to the side slightly, and replied with a serious face: "That's because Dr. Song has a habit in the morning, that is, he will drink a cup of coffee that I poured by hand. After saying this, a shy smile briefly appeared on Xu Wen's face. Maybe even she noticed that her state was abnormal, so she immediately returned to a serious and sad expression.

Wang Shen carefully observed Xu Wen's expression and saw that Xu Wen's eyebrows were full of sadness. But this kind of grief is not easy to detect. Because above the sadness, there is another strong emotion that occupies Xu Wen's heart. Wang Shen couldn't tell what this emotion was for a while. In short, Wang Shen looked at Xu Wen's eyes and felt very depressed.

"Oh?" Wang Shen deliberately raised his tone, and his face turned very surprised.

"When I went to deliver coffee to Dr. Song this morning, I didn't respond to any knock on the door. I could only see a very vague figure of Dr. Song outside the consultation room. But I didn't go in at this time because I knew that Dr. Song didn't like 'uninvited guests'. After saying this, the gloom in Xu Wen's eyes appeared again. I thought Dr. Song was working all night and was too tired to fall asleep. It is not uncommon for Dr. Song to work all night. But Dr. Song is a person who is extremely strict with himself, almost to the point of being harsh. He used to drink coffee at 7 a.m., and he never seemed to change this habit. I started to think something was wrong, but I waited for another twenty minutes. The second time I knocked on the door, Dr. Song still didn't respond. I stood outside the door and thought for a while, then decided to push the door open and go in to have a look. Speaking of this, Xu Wen began to choke, covering her mouth with one hand, trying her best to suppress her sadness.

Wang Shen handed a tissue to Xu Wen. Xu Wen said thank you and gently wiped the tears that had not yet flowed from the corners of her eyes with a tissue. I pushed open the door and found Dr. Song sitting nicely in his chair. To be honest, I was so relieved at the time. I called Dr. Song again, but he still didn't respond. At this time, I realized that Dr. Song's sitting posture seemed a little strange. As I said earlier, Dr. Song is an extremely strict person with himself, and he will never allow himself to collapse in a chair like this. My hand holding the coffee cup was shaking. I slowly approached Dr. Song. When I saw Dr. Song's face, I was shocked and my coffee cup spilled on the carpet. After speaking, Xu Wen picked up the tissue in her hand and kept wiping the tears from the corners of her eyes.

"So that's when you called the police?" Wang Shen also recorded the information provided by Xu Wen in the notebook.

Xu Wen was still choking, and only nodded sadly when she heard Wang Shen's question.

"You mentioned that the coffee spilled on the carpet?" Wang Shen immediately turned his attention back to the consultation room.

Xu Wen nodded again.

"What kind of cup did the deceased use every time he drank coffee?"

"It's those coffee cups." Xu Wen pointed to the tea area not far away and said.

Wang Shen walked in the direction of Xu Wen's finger and saw a coffee machine on the table in the tea area, as well as some hand pouring utensils, and some mineral water. "These are the cups? Did the deceased have a designated cup? Wang Shen took plastic gloves and picked up one of the cups to observe.

Xu Wen shook her head again.

There are three sets of coffee cups on the table, which are ordinary styles. "Who else would use these coffee cups except for the deceased?"

"Sometimes some big customers, or people who are close to Dr. Song, will use these cups." Xu Wen stared at the cup in Wang Shen's hand and answered Wang Shen's question.

Wang Shen looked at Xu Wen and carefully analyzed what she said, feeling a little strange. Just now Xu Wen mentioned that Song Mu is a person who is very strict with himself. For such a person, Wang Shen has a character stereotype in his heart, that is, cleanliness. This type of person is as demanding of himself as he is of others. If you are not someone you fully trust, you will not feel at ease to hand yourself over to the other party.

Back to the question of the coffee cup. If Xu Wen replied that Song Mu had a coffee cup that he used specifically, Wang Shen would still believe it. But Xu Wen said that the cup Song Mu used was any of the three. Such an answer had to make Wang Shen suspicious. Of course, there are exceptions. As for the truth, Wang Shen still needs to follow up the clues himself.

Thinking of this, Wang Shen turned around and walked into the psychological counseling room again. Wang Shen walked quickly to the carpet of his desk and squatted down. Wang Shen was carefully searching for the coffee stain that Xu Wen had said. Sure enough, right next to the desk, Wang Shen saw this piece of coffee stain.

No, Wang Shen's eyes froze for a moment, there was something wrong with this coffee stain. Wang Shen observed the placement of Song Mu's desk. Song Mu's desk is on the left-hand side facing the door of the counseling room. According to the logic of a normal person, Xu Wen pushed the door in from outside the office and walked directly to Song Mu. When it was found that Song Mu was dead, he should have stood on Song Mu's left side, and should not have gone around to Song Mu's right side again.

Moreover, the biggest suspicion is that Song Muben is a left-hander. As a secretary, Xu Wen should have known Song Mu's habit for a long time, so it is even more impossible to put the cup on Song Mu's right hand when delivering coffee.

Wang Shen took a closer look at the coffee stain again, and motioned to the police behind him to collect evidence on the coffee stain. Wang Shen stood up and glanced at Xu Wen who was standing behind him. This woman must have something hidden in her heart!
