I said nonchalantly

"I always thought you had an alibi, so I didn't think about it, but since your alibi is fake, it reminds me of something."

"What's the matter?" Zhang Kexin became Ke Hezi's spokesman at this time, and asked for her.

"As Jiang Junqian said, Roy is a foreigner who is very bad at Chinese, there are many words he can't write, and if he wants to write down the murderer's name before he dies, he can only use English, or pinyin."

"So what? What exactly are you trying to say? Zhang Kexin asked impatiently

"I want to say, the pinyin of the word Ke is Ke, so is it possible that the death message that Roy wants to leave is Ke?"

When Ke Hezi heard this, he was rightly furious

"Dead fatty, don't talk nonsense!"

Zhang Kexin also echoed

"Yes, Song Yang, don't talk nonsense if you don't have evidence."

I don't care what Ke Hezi says, because I don't know her very well, but Zhang Kexin asked me again and again, and now even the title has changed, and my good temper is over, I stood up, moved my shoulder, and said angrily

"We previously speculated that the killer was someone Roy knew, and she didn't have an alibi to be in touch with K, so I suspect she should be."

Zhang Kexin said coldly

"We just have to go to the gate and check the surveillance to see what time she leaves and what time she returns."

"I'm going to teach you a simple method, if she's a murderer, let's say she leaves the gate at 2:40, then evades the surveillance, climbs over the wall to enter the school, kills Roy and then climbs over the wall and goes out, and then comes back from the gate after 3 o'clock, so that it looks like she's not at the school at all between 2:40 and 3:00." I'll admit that I said this in utter anger and nonsense, but I was really annoyed and reckless.

"Dead fatty! You! ”

"Your imagination is so rich, go write a novel! Are you an idiot? Zhang Kexin's words completely ignited my anger, and I said with a slight threat

"Are you stunned by this woman? I'm just saying what I think, you dare to talk to me like that, do you want to die? ”

Zhang Kexin was not afraid, leaned his face forward, and said sharply

"Do you have what it takes?"

Guo Hongyi and Su Yongsheng were afraid that the two of us would really make a move, so they hurriedly crossed between us

"Are you two really crazy? It's all a buddy in the dormitory, do you really want to do it? ”

Guo Hongyi made me calm again, after all, the man in front of me has to live with me for four years, I don't want to make the relationship too embarrassing, Zhang Kexin is more mature and stable than me, and naturally I won't do it, after the impulse has passed, the two of us will no longer be entangled too much.

I turned my head to Guo Hongyi and said

"Let's each do what we're good at, I'll solve the secret room technique, you go and ask for some information, and see if there are any other international students who have contact with Roy, and there is K in his name."

The implication is that the murderer may be someone other than Ke Hezi, and when I say this, it is equivalent to being subdued in disguise, Guo Hongyi breathed a sigh of relief, smiled and said to Zhang Kexin

"Look, Yang'er didn't mean that." He turned to me again

"But, Yang'er, isn't it a new job to get information? I'd better go with you to the international student apartment to find clues. ”

I said angrily

"That guy only wants to do one thing now, what other information can he get, you go."

"Huh? What's the matter? Guo Hongyi glanced at Zhang Kexin and asked curiously.

I picked up my down jacket and walked out the door without looking back, and said angrily

"Of course, he wants to follow the route of Ke Hazi last night and ask if anyone has seen her, so as to prove her innocence."

After walking out of the teaching building, I scolded Zhang Kexin for being heavy on sex and light on friends, not righteous enough, and turned his face to me for a woman I only met last night, and after venting my emotions, I forced myself to calm down, and analyzed the case while walking towards the international student apartment

"Now there are four people who have no alibi and can make Roy open the door at night: Ke Hezi, Qu Lian, Jiang Junqian, Xia Nanxing, among them, only Ke Hezi and Qu Lian can be contacted by K, if Zhang Kexin didn't have an emotional relationship with me, with his ability, he can definitely find more connections between these two people and Roy, and now the only one he can rely on is Guo Hongyi, but what is that unnatural feeling just now? Hurry up and remember! ”

Thinking about it, I had already arrived at the door of the international student apartment, and Officer Hu had already greeted me before, so I entered Roy's dormitory without any hindrance.

At this time, Roy's body had been removed, and the ground was also covered with circles and lines drawn by the police of the Identification Section, Officer Hu asked when he saw me come in

"Why are you alone? What about your partner? ”

I casually snorted and said

"Oh, they've gone somewhere else to find out."

Officer Hu said with some dissatisfaction

"Hey, I don't know if it's because people are doing too much bad things now, and it's not as easy for the police to ask questions as ordinary people, but it's good that you're here, come and see this secret room, do you have any ideas? I'm at a loss right now. ”

Hearing Officer Hu say this, I was a little proud and thought to myself

"That's it, I'm the core of the detective team, as long as I am, the case can be solved."

The second time I entered the dormitory, I felt much calmer, and with Roy's body removed, I was able to observe the room more intently: the curtains had been pulled open by the police, and from the markings they had made, the windows were indeed locked, and the whole room looked like a secret room.

I asked, looking at the row of clear glass at the top right of the door

"Officer Hu, is it possible that the murderer took that piece of glass off, threw the key in, and glued the glass back on?"

Officer Hu shook his head and said

"I thought of this at first, but after we checked it, we confirmed that the glass glue on it had been applied for at least 2 or 3 years, not new, so we ruled out this possibility."

"It's not that simple."

I try to think like Zhang Fan, who always learns from Sherlock Holmes: "Put aside all the impossible, and what remains, no matter how unbelievable, is the truth." ”

"There's only one door and glass here, and if you haven't touched either of them, then it's probably the window."

The situation on the other side of the window is much more complicated, with a closed window, a bed, a bedside table about 60 cm high, a hanger about 180 cm, a study desk, a computer, and a printer.

This scene reminds me of a scene where one end of the rope holds the key, and then the rope is placed on top of these things one at a time to form a track, and the murderer pulls the other end of the rope outside, and the key enters the room through the crack in the door.

"No, if the key is really tied to one end of the rope, if you go in, how do you separate the rope from the key?"

Thinking of this, I scratched my head, and naturally took out the phone to get an answer from Zhang Fan, but the moment I was about to dial the phone, I recalled Wang Jing's sentence "Obviously your teacher told you the answer" Although I knew that her words were a joke, but it still stabbed my self-esteem, although I also knew that murder was not a matter of anger, but I still wanted to prove myself, put the phone back in my pocket, and planned to solve the case alone.

"I'm the core of the TLH detective team, I'm the core of the TLH detective team..."I hypnotized myself repeatedly, and it was easy to make up my mind, but if I really wanted to solve the problem, it was not so simple.

"How the hell did the killer get the rope to separate from the key, and was that crack in the door really enough to let the key in? In other words, it was simply wrong, the murderer used other methods to create the secret room. ”

"Are you wondering how the killer got out?" Officer Hu interrupted my train of thought, and I said as a matter of course

"This is natural, how can the murderer be caught without revealing the mystery of the secret room."

Officer Hu had a different opinion, and said in a tone like a teacher instructing students

"I find that you will always fall into a strange circle, every time you solve a case, it seems that you are testing your intelligence with the murderer, but in fact, the key to solving the case is to find the murderer, not to solve the puzzle."

I asked, puzzled

"Officer Hu, what do you want to say?"

Officer Hu continued to speak earnestly

"Generally speaking, we have to find out the murderer's method of creating the secret room, in order to determine whether the case is suicide or homicide, but in this case, the deceased was stabbed twice, ruling out the possibility of suicide, so it is certain that the secret room was forged by the murderer, since we have determined this, then the murderer's method of creating the secret room is no longer important, what matters is who the murderer is."

Officer Hu's words are like an enlightenment, after Officer Hu's guidance, I also suddenly realized that Officer Hu is right, solving the case is to find the murderer, not to prove that I am smarter than him, and this case, judging from the current situation, even if the murderer's methods are cracked, he may not know who he is, it is better to lock the target according to the clues, find the decisive evidence, catch the murderer, and let him tell him how to create a secret room.

I said approvingly

"Officer Hu, you're really right."

Officer Hu said with a wry smile

"After all, our starting points are different, solving cases is not your main business, it can even be said to be a hobby, and I am a policeman, my responsibility is to catch the murderer, not let him go unpunished, and redress the victims."

I looked at Officer Hu blankly, deeply moved by what he said, he seemed to be an easy-going uncle on the surface, but deep down he had a strong sense of responsibility and mission.

According to Wang Jing, Zhang Fan is the teacher who taught me reasoning, and Officer Hu is the teacher who taught me to solve the case, I nodded firmly, saying that I will never disappoint Officer Hu, and Officer Hu also smiled and patted me on the shoulder to cheer me on.

Since I can't figure out how to create a secret room for the time being, let's see if there are any clues, I asked

"Officer Hu, is there anything strange?"

Officer Hu's eyes became deep, and he said

"Judging from the traces of blood on the deceased's body and on the ground, the deceased tried to resist after being stabbed for the first time, and then was stabbed by the murderer for the second time, and then completely lost the ability to resist and fell to the ground, leaving K and dying."

I asked, confused

"It's... What's the strange? ”

Officer Hu explained

"According to my years of experience in handling cases, if a man attacks the victim with a knife, the victim's first reaction after being stabbed is definitely to run away, but the deceased in this case has no intention of running away, in other words, he believes that even if he is stabbed, he still has the ability to subdue the murderer."

"And what does that mean?" I asked

"It shows that either the murderer is a disabled person, or a person with little strength, such as a child, an old man, or a woman, but after our investigation, in China, the deceased does not know any disabled people, children, or the elderly."

Unexpectedly, Officer Hu usually looked confused, analyzed the case, and really said that Officer Hu's words were like a guiding light, illuminating the direction for me, and following Officer Hu's words

"The murder weapon is the fruit knife in the deceased's room, it can be seen that the murderer is a temporary murderer, we said before, Roy can still let the murderer in so late, it must be an acquaintance, so the murderer is only a woman who may be known to Roy."

"Hmm." Officer Hu nodded and said, "That's all I can analyze now, let's work together to find the murderer." ”

I nodded, followed Officer Hu's train of thought, and re-analyzed the case

"The murderer is a woman known by Roy, and the only known ones are Bai Zhi, Ke Hezi, Qu Lian, and then count one Wang Jing, among which Bai Zhi and Wang Jing have a perfect alibi, so it can only be Ke Hezi and Qu Lian, which seems to confirm my previous conjecture, but think about it calmly, just because of the relationship between Qu Lian and King, it seems a bit far-fetched to say that she has a connection with K, Ke Hezi seems to be more in line with K's death message, but, what about the motive? What reason does a rich second generation have to kill an international student? ”

Thinking of this, I felt a little sorry for Zhang Kexin

"How can I ignore this, I said very abruptly that Ke Hezi was the murderer, and I quarreled with Zhang Kexin, hey... Do you want to apologize to him, but, sorry three words, is it so easy to say? ”

After another hour, I said hello to Officer Hu

"Hey, Officer Hu, I know all the clues here, I'll go to my friend's side to see if they find anything, if there are any clues here, call me and tell me."

After Officer Hu agreed, I left the student dormitory and dialed Guo Hongyi's phone

"Hey, Brother Guo, it's almost over my side, but what about you? Yes? You're back at the hotel now, okay, I'll go back to you now. ”

After putting away the phone, I was about to walk towards the school gate, and saw Wang Yuesha walking in my direction, meeting on a narrow road, I couldn't turn around and leave at this time, I just hoped that she could be like me, pretending not to see each other, just pass by, but Wang Yuesha seemed to be born to make me unhappy, blocked my way, and said coldly

"Sure enough, you are a man who can attract blood."
