Officer Liu's tone was very resolute, and Peng Ligang couldn't refute him, so he had to open the door and call the next one in. It was Dr. Du Tengwu who came in, and Dr. Du looked a little lost, as if he was worried about something.

"What were you doing between nine and ten o'clock last night?" Officer Liu was as calm as ever, as if nothing had happened just now.

"I went to bed very early last night, and I was on top of my bed at about nine o'clock, and it didn't take long for me to fall asleep." Du Tengwu said.

"Why do you go to bed so early?" Officer Ji obviously didn't believe Dr. Du's words and continued to ask.

"It's always been a habit of mine, because I have surgeries every day, so I go home and sleep after work. Before nine o'clock, you will definitely lie down in bed, even if you can't sleep. Dr. Du continued to answer, his tone still so calm.

"Got it, you go out first, and please call the next one in." Officer Liu didn't seem to be going to continue asking, and let Du Tengwu go out first.

It was Fang Xinhui who came in, and Fang Xinhui was still the same old look, and she didn't care about the murder. Peng Ligang pointed to the chair and motioned for her to sit down first. Fang Xinhui sat down and said, "Are you going to ask me what I was doing last night?" I was bored in my room alone last night, so I took a random shot with my camera. But to be honest, the night view here is pretty beautiful, so I'll show you the camera, it's really beautiful. ”

"From nine to ten o'clock last night, did you hear any movement in Miss Lin's room? You live across from her, and if someone comes in or out of her room, you're going to hear it. Officer Liu glanced up at Fang Xinhui and asked.

"Well, I didn't hear it, because I've been listening to music, and besides, the door to my room is closed, how could I hear someone coming in and out of her room, maybe it's a waiter, did I also come over to take a look." Fang Xinhui put her hands on the armrests of the chair and said dissatisfiedly.

"Alright then, there's nothing else to do, please call the innkeeper in." Officer Liu closed the notebook and said lightly.

Fang Xinhui walked out of the room and followed the innkeeper in.

"Boss, did any outsiders come in from nine to ten o'clock last night?" Officer Liu put the pen and notebook in his pocket, patted the dust on his black suit pants, and asked.

"No, I was at the front desk with Sister Zhang and Sister Luo last night, and Sister Luo went out at nine o'clock and didn't come back until ten o'clock. Because of yesterday afternoon's incident, I ran to that room from time to time to take a look, when Officer Liu was there, Sister Luo also went to see him from time to time, I guess you also saw him. Because we went in turns, the front desk was always there and no one came last night. The boss said and looked at Officer Liu.

"Is there a back door or anything like that in the hotel, or a place for outsiders to enter?" Officer Liu walked over to the balcony and took a look.

"No, the first and second floors are equipped with security nets, and the only way to enter and exit the hotel is through the main entrance, but if you enter through the main entrance, someone will definitely see you." The boss sat straight in his chair and replied.

"Got it, you go get busy first." Officer Liu said as he looked at the scenery outside the balcony.

After the innkeeper went out, Peng Ligang also walked to the balcony, Peng Ligang didn't speak, but Officer Liu said first: "Luo Yutong was my girlfriend when I was in college, and I wanted to take the postgraduate examination for forensic medicine at that time, but the number of places was limited, if I didn't give gifts to the leader and go through the back door, I wouldn't have been able to get that opportunity at all." But my family has always been poor, and my family is already in debt for my college education, and I really can't come up with the money. Yutong's father has chronic leukemia and urgently needs money for surgery. We tried a lot of ways, and on a few occasions I secretly sold blood without her, but the money was still not enough. “

Officer Liu paused here when he said this, Peng Ligang found that his eyes were moist, took a pack of tissues from the TV cabinet and handed it to him, Officer Liu wiped it twice and continued: "One night, Yutong suddenly called me and asked me to go to the bank to check, saying that she had remitted a sum of money. At that time, I was already crazy, and as soon as I heard that the money was being remitted, I didn't even think about it, so I ran to the bank with my phone, and took the money out of several ATMs and went to the leader's house with the money. ”

"And what about later? Why did Miss Luo suddenly commit suicide? Peng Ligang saw Officer Liu stop and asked.

"It wasn't until the next morning when the police called me that I learned that Yutong had committed suicide by jumping off the building, and the police didn't tell me any reason, but only took out a suicide note to me. The suicide note was written by Yutong herself, but she didn't say where the money came from, just asked me to take care of her father on her behalf. Later, I was successfully admitted to graduate school and was assigned to the Municipal Public Security Bureau as a forensic doctor, but I have always been worried about this matter. I took advantage of my work to often go in and out of the "Shihao Hotel" to investigate the truth about Yutong's suicide two years ago, but all the employees there either said that they had forgotten or had been replaced, so they never found any clues. Officer Liu looked into the distance affectionately and said softly.

"Then why did you suddenly travel to Chengde alone this time, it should be more than just that you want to come and relax, right?" Peng Ligang asked questioningly.

"Of course not, although the forensic doctor is not an official, there are many things that happen every day. I came here after receiving a call from a mysterious person, who said that the real murderer of Yutong would of course die on this trip, and that I must come. Officer Liu said.

"Mystery man? Have you checked the source of the call? Peng Ligang suddenly felt that things had become strange.

"I checked, it was from a pay phone, and the mysterious man seemed to be using a voice changer, and I couldn't tell if it was a man or a woman. For the sake of prudence, I took a leave of absence, and as a police officer, of course, I can't ignore such a thing, although I also want to take revenge. Officer Liu was a little disappointed and walked back to the room from the balcony.

"It seems that the murderer must be the mysterious person, he must be someone in the tour group." Peng Ligang said.

"Perhaps, I'll go back to my room first." Officer Liu opened the door and walked out.

Peng Ligang also walked out, the corridor was empty, and everyone had already returned to their rooms. Peng Ligang was about to go back to the room when the door of Fang Xinhui's room suddenly opened. Fang Xinhui held a camera in her hand and wore a sportswear, as if she was ready to go out. Peng Ligang looked up and suddenly asked, "Can you show me your camera?" “

Fang Xinhui hesitated, but still handed the camera to Peng Ligang. There are a lot of night scenes in the camera, but they were actually taken last night, and it seems that Fang Xinhui is not lying. It's just that the night scene looks a little blurry, and it seems to be a little different from the scenery taken during the day.

Maybe it's because of the night, so some buildings were not photographed. Peng Ligang returned the camera to Fang Xinhui and said to her: "You can't go out now, you can't wait until tomorrow, you are still staying in the room honestly." ”

After speaking, Peng Ligang continued to think and walked towards his room. The door to the room was open, and Peng Ligang walked in.

The waiter's aunt was making the bed, watched Peng Ligang walk in, and said to him, "Mr. Peng, you went to the wrong room, your room is on the opposite side." “

Peng Ligang glanced at the house, then retreated to the door and looked again, there was no house number on the door, and all the doors were the same, no wonder Peng Ligang would go wrong. Peng Ligang smiled and said sorry, and was about to turn around and leave, when he suddenly saw the blood-stained sheets being thrown on the ground, and the waiter was laying out new ones.

Peng Ligang's mind flashed, all the complicated things were linked together, and Peng Ligang suddenly understood everything. Rushed out of the room in a hurry and ran towards Lin Liwen's room.
