After leaving the hospital, Ma Lu asked Mu Chun in the police car, "Brother Zhang has already told me what happened here in Yuchuan a few days ago, and Dr. Mu Chun was the first person to discover Deng Lin, my colleague has also learned about the situation from you before, I don't know what Dr. Mu Chun thinks about this matter, I just heard you say to Zhao Xue, let her ask the reason for her daughter's suicide, is Dr. Mu Chun convinced that Deng Lin committed suicide?" ”

Mu Chun understood the question of the road. Mu Chun also answered Ma Lu very clearly, "There are many doubts. ”

"Suspicious?" Ma Lu wondered.

So Mu Chun suggested that Sumikawa Medical College was nearby, so why not go again together.

Ma Lu said he was looking into something.

Mu Chun asked, "Is it a matter of express delivery?" ”

Ma Lu was surprised and asked, "How did the doctor find out that there was a problem with the delivery?" ”

"The first is time, it happened that after Deng Lin left the police station that morning, she suddenly called back to the police station and said that she had withdrawn all the previous charges, and there was no voyeurism and no underwear theft, which was very incredible; Second, who sent the express? There was a problem with this matter at the beginning, during the winter vacation, it was absolutely impossible to send the express to the 212 dormitory, the university's express delivery is generally placed somewhere for everyone to pick it up, at the door of the cafeteria, downstairs in the dormitory, a little better There is a special smart box to store the express, but most of them have to go to the designated place to pick up the express delivery.

How was this courier delivered to Deng Lin? When I first went to the third dormitory building, I found a shelf in the dormitory room, and there were two couriers on the shelf, which should have not been picked up during the winter vacation. ”

Ma Lu immediately said after hearing this: "Indeed, express delivery is a big problem, I confirmed with the two girls who called the police before that these underwear found in Deng Lin's dormitory were indeed lost by them before." ”

"Well, then we can deduce that Deng Lin must be related to these missing underwear, and because these underwear suddenly appeared, she will withdraw the charges against Zhou Gang."

Halfway through Mu Chun's words, Zhang Hai snapped his fingers, and continued: "Zhou Gang is naturally not suspicious. ”

"It can be said that it is not complete, because Zhou Gang is indeed holding Deng Lin's underwear, which is also true." Mu Chun then finished the sentence just now.

"To be honest, Doctor Mu Chun, I originally thought it was a little thing of a girl's hypocrisy, and I even secretly thought about it, do you know that a group of female drivers want the police to go over and issue a ticket because they like a traffic policeman on Lingchuan Road?"

Zhang Hai grinned after speaking, revealing a weird smile that was completely different from his usual seriousness, honesty and reliability.

"What do you mean?" Ma Lu didn't understand at all, so he asked curiously.

Zhang Hai said with a smile: "I thought that little girl had a crush on us Liu Yiming, so I called the police once or twice, and asked us to go to the dormitory to protect her, I thought she was just making Miss Temper." ”

"I see." Ma Lu laughed heartily, "Liu Yiming seems to be more popular with girls than when he was in the police academy, probably more and more responsible, and his temperament is getting better and better." ”

"It's not impossible." Mu Chun said, "Maybe it was like that from the beginning. Let's get down to business first, what is certain is that the theft of underwear must be related to Deng Lin, she should have taken the underwear of the other two girls and threw away the underwear, but just like Zhou Gang picked up the underwear, someone did pick them up. ”

"How could you just pick it up?" Both Zhang Hai and Ma Lu have such questions.

"This is the story of waiting for the rabbit, it seems the most unlikely, but in fact it is very likely, if what Zhou Gang said is true, it can be assumed that he is used to passing downstairs in the third dormitory at that time, as for why he wants to take that path, the reason can also be very simple, he just likes dark places, that is, he likes to listen to the sound of girls talking in the dormitory building on the first floor, and even sneaks a few glances at the girls in the dormitory from the window, there is no other reason in particular, this is the only reason, a strange hobby, not as serious as voyeurism. ”

"Zhou Gang is a patient of Dr. Mu Chun, no wonder Dr. Mu Chun can think of this." Zhang Hai said.

Mu Chun immediately agreed with Zhang Hai's statement, "Yes, indeed, if it weren't for Zhou Gang who happened to be my patient, and he told me about some of his hobbies, I might not have thought of it, after all, this trail is really not a road that normal people would use for walking." ”

Speaking of which, the three of them had already arrived at the gate of Sumikawa Medical College, and this time, Zhang Hai parked the car outside the south gate again.

When the three of them walked into the south gate, Liu Dong came out again to say hello, and then asked, "Comrade police came to handle the case again, is that girl okay?" ”

"You're the security guard here?" Ma Lu asked.

Liu Dong nodded again and again, "Yes, yes, I am." ”

"How many years have you been working here?" Ma Lu took out his notebook and began to record.

"It's been almost thirty years." Liu Dong said.

"Thirty years? Always working as a security guard here? Ma Lu frowned, and Mu Chun also felt a little strange, so he turned to look at Liu Dong.

'Liu Dong', this name suddenly caught Mu Chun's attention.

"Has anything strange happened lately?" Ma Lu asked again.

"No, everything has been normal lately, I've got surveillance here, nothing has happened except for what happened to the girl upstairs two days ago." Liu Dong spoke very slowly, and Mu Chun found that his expression was slightly different from two days ago, and it seemed that the whole person was much more relaxed.

"By the way, do you have the surveillance records from two days ago, January 26th?" Ma Lu continued to ask, and due to the cold weather, Ma Lu's writing hand looked red.

'January 26, Liu Dong'

'The dormitory building where the accident happened, thirty years ago. ’

Suddenly, a biting chill made Mu Chun suddenly feel terrified.

It was as if he had seen the scene of thirty years ago unfolding in this abandoned dormitory building.

Thirty years ago, on January 26, just before the Lunar New Year, a girl slit her wrist with a scalpel in her dormitory.

The window of this dormitory building is directly facing the dormitory building No. 212 where Deng Lin is located.

The name of the girl who died was Liu Min.

Mu Chun turned around and walked towards the dormitory building that was no longer in use, the sound of the road behind him became more and more blurred, and he walked very slowly, until Liu Dong shouted behind him: "What are you doing, you can't go there." ”

Ma Lu and Zhang Hai turned around, only to find that Mu Chun had walked to the dilapidated fence outside the dormitory building.

"Don't go there, you can't go in there." Liu Dong staggered behind Mu Chun and patted him on the shoulder.
