When it was dark, Ling Guodong told us that the preliminary investigation of the scene had been completed, and the footprints that were not extracted in the room showed that no one had entered that night, and the chairs in the room had been moved, which were originally placed on the writing desk, but finally appeared in the middle of the room.

There are two chairs, one is still in the middle of the room, and the other is the one that Su Fengmei sat on after her death, as for why it was placed like this, it is not clear.

"Did you find this room particularly cold inside?" Ling Guodong shuddered when he said this.

I also felt it from entering this room, although it started to rain last night, the temperature in this room was not so cold, but I didn't care, Yun Duruo asked Ling Guodong to continue.

"By the way, has Su Fengmei's time of death been confirmed?" Ling Guodong asked me rhetorically.

Su Fengmei's body has been sent back to the bureau, Chu Tianqi followed back to do a preliminary autopsy, he called and said that according to the liver temperature of the corpse, Su Fengmei's death time was between eleven o'clock last night and two o'clock in the morning.

Ling Guodong frowned deeply after hearing this, and said to me and Yun Duruo, it would be very strange, I had surveyed that the iron gate had no traces of being damaged and forcibly opened, and the nurse Geng Lin said that it was nine o'clock in the evening when she went to find Su Fengmei with her documents, and Su Fengmei was still alive at that time, if the murderer wanted to kill Su Fengmei, entering the iron gate would be heard by Geng Lin.

During the period from Geng Lin's call to the police, the iron gate was not opened, which means that the murderer did not leave, but it rained last night at about eight o'clock, and if the murderer went in before the iron gate was closed, he would definitely leave footprints, but he did not find it at the scene.

"Or maybe the killer went in before eight o'clock?" Yun Duruo asked with a stern expression.

"Then it doesn't make sense, Geng Lin found that the iron gate was closed at half past nine, and Su Fengmei's death time was from twelve o'clock to two o'clock in the morning, even if the murderer went in early and left no footprints, but after the murder, how did he leave, the iron gate was closed at that time." Ling Guodong shook his head and replied in surprise.

"Windows!" I pointed to the position where Su Fengmei was sitting just now. "Could it be that he left through the window after the murder?"

"In the garden below the window, we only found Geng Lin's footprints, nothing else, and her footprints were not under the window, she was standing on the edge of the garden and looking at the situation inside the window." Ling Guodong still shook his head and sighed. "I'm sure no one has ever left this room through a window."

"How did the murderer get out of here?" Yun Duruo and I both looked at each other after hearing this, and the murderer seemed to come and go like a ghost and disappeared at all, Yun Duruo asked in surprise.

"That's not something I'm going to think about." Ling Guodong spread his hands and replied helplessly to Yun Duruo. "It's going to be hard work on how to leave, so you have to think about it."

"Others? What else did you find? I asked Ling Guodong.

"Oh, yes, one more thing I forgot." After Ling Guodong finished speaking, he took out a piece of paper and handed it to us.

He told us that Su Fengmei has the habit of cleaning up the garbage every morning, but the trash can in the room is clean, Su Fengmei died last night, she can't take out the garbage, the only possibility is that the murderer took the garbage.

The people in the forensic department found a piece of shredded paper in the trash can, and there was no text left on it, but the same paper was found in Su Fengmei's drawer, and there was a deep mark on it, Su Fengmei should have written it on the paper, and it was written repeatedly so that it would be left.

Ling Guodong asked people to restore what Su Fengmei wrote according to the imprint.

Yun Duruo and I only saw three words on the paper that Ling Guodong handed us.

Mu Hanzhi!

Yun Duruo and I were stunned when we saw this name, it seemed that this name had become a curse, and anyone who was involved with this name would never recover.

On the paper, I found that there was a long string of exclamation marks written on the back of Mu Hanzhi's name, but there was a longer row of question marks below, and it could be seen that Su Fengmei was in a very confused mood when she wrote this name, she should know Mu Hanzhi very well, I can understand the exclamation mark at the back, but what does the question mark mean?

Yun Duruo wanted to find Geng Lin, who was on duty last night, to learn more about the situation, I was going to rush back to the bureau to do a detailed autopsy on Su Fengmei, but Yun Duruo said that she was afraid that the authorities would let me go with me.

The crimson corners of Geng Lin's eyes should be sad for Su Fengmei's death, I have already read Su Fengmei's file, she has been working in an orphanage at the age of sixty this year, kindness, gentleness and amiability are the most evaluations of her, she has dedicated her love to orphans all her life, and she is a very respected person.

Geng Lin described Su Fengmei to us is the same, she is very sad and doesn't understand, how could someone like Su Fengmei be killed, Yun Duruo handed over a tissue to comfort her, we found a place to sit down, Yun Duruo asked Geng Lin very seriously, when she was on duty last night, was there anything special or abnormal.

"I went out to check last night, and just walked downstairs, I vaguely heard someone singing?!" Geng Lin was also a little puzzled when she said this. "It's not like singing, it's like, it's like it's ......"

"Peking Opera?" I saw that Geng Lin had been trying hard to recall the voice she heard, but she couldn't describe it, so she subconsciously asked.

"That's right! It's Peking Opera! I'll just say how weird it feels. Geng Lin thought about it for a while, and said with certainty. But I've never heard the dean sing Peking Opera. ”

"And then?" Yun Duruo asked eagerly.

"At that time, I also wondered how the dean could sing in the middle of the night, so I wanted to go and see it." Geng Lin replied intently. "But when I got to the iron gate, I didn't hear anything, and I wondered if I had heard it wrong."

"Do you remember what time it was?" I asked seriously.

"It was half past twelve in the evening." Geng Lin replied in the affirmative.

I looked at Yun Duruo thoughtfully, Geng Lin should have heard it right, what she heard should be "Mandarin Duck Tomb", and this song has a special meaning for Su Fengmei, the murderer relied on this voice to lead Su Fengmei to open the door, judging from Su Fengmei's cause of death, the murderer is likely to break her cervical vertebrae after Su Fengmei opened the door, which is why Geng Lin's voice did not appear again after going to see the iron door.

"Anything else?" Yun Duruo continued to ask.

"And ...... There's one more thing I'm supposed to be dazzled, and I'm not so sure. Geng Lin said again and again.

"Tell me what to do first." I calmly let Geng Lin continue.

Geng Lin said that after she came back from the ward round in the middle of the night, it was about one o'clock in the morning, the rain was very heavy and accompanied by thunder and lightning, when passing by Su Fengmei's room, a lightning bolt illuminated the small building, Su Fengmei's window was blocked by a curtain, there was no light inside, Su Fengmei should have slept at that time, but Geng Lin saw the shadows of three people coming out of the curtains under the lightning.

"Three people?!" Yun Duruo's brows furrowed even deeper when he heard this.

"Yes, I also felt so strange at the time, the dean had been living alone all the time, and it was still night that there could be no one else in her room." Geng Lin nodded and continued to reminisce. "I was worried that something would happen, so I wanted to go over and see, and then there was another flash of lightning, and the shadow that came out from behind the curtain turned into a man."

Yun Duruo and I listened in the clouds, and we didn't understand what Geng Lin saw at all.

"And then?"

"Later, I walked to the place where the iron gate was, and found that the iron door was locked, thinking that it was impossible for anyone to enter at that time, and I was still a little puzzled, but when I saw the dean appear by the window, I thought that there was nothing wrong, maybe it was too rainy, and I was dazzled, and then I went back to the duty room." The more Geng Lin spoke, the more strange it was that there was deep blame in his voice. "The light in the dean's room has been on since that time, and the dean is sitting by the window like that, and I can see it from the window of the duty room, and I didn't think it was strange at first, but when it was dawn, I found that the dean had been motionless and kept the same posture......"

Geng Lin cried bitterly when she said this, Yun Duruo and I didn't know how to comfort her, according to Geng Lin's description, Su Fengmei was killed after opening the door, but Su Fengmei appeared by the window at one o'clock in the morning, and in the half hour after Su Fengmei's death, what did the murderer do in the room?

After Geng Lin calmed down, Yun Duruo asked her very softly.

"On the day Su Fengmei was killed, was there anything particularly unusual about her, or did she see anyone?"

"There's something unusual about the dean, but not from last night, but from a few months ago." Geng Lin wiped the tears from the corners of her eyes and replied seriously. "But yesterday the Dean was much more flustered than before."

"You can be more detailed, why was Su Fengmei so flustered yesterday?" I comforted Geng Lin with a pleasant face.

Geng Lin told us that Su Fengmei has been worried about this period of time, as if she has something on her mind, she seems to be a different person from before, always with a solemn face and often distracted, yesterday Geng Lin went to give Su Fengmei the newspaper of the day, and it was fine at first, but after reading it for a while, Su Fengmei was very frightened. Transcript:.

I asked Geng Lin if the newspaper was still there, Geng Lin took it out from the drawer next to him, Yun Duruo and I looked through the newspaper carefully, there must have been something on it that stimulated Su Fengmei, until Yun Duruo put a page of news in front of me.

The above is the news about Liu Yuewu falling to his death!

Why was Su Fengmei so shocked when she saw the news of Liu Yuewu's death?

I looked at Yun Duruo, whose face was full of doubt, and shook my head.

"Su Fengmei is not frightened by Liu Yuewu's death, the common point between her and Liu Yuewu is Mu Hanzhi, Su Fengmei is frightened by the person who pushed Liu Yuewu downstairs, and the source of her fear is Mu Hanzhi."

"But there is nothing about Mu Hanzhi in the report, how does she know?" Yun Duruo asked puzzled.

My eyes looked at Geng Lin, it seems that Su Fengmei knows that Mu Hanzhi has far more things than us, which is why Geng Lin said that Su Fengmei has been worried recently
