Fire to the Abyss

A member of the detective agency died of cyanide poisoning on Christmas Eve. The discoverer was the current president. It was supposed to be a sensational news, but a week later, the police announced that it was most likely an accident.

The reason is that on the afternoon of the 25th, Li Xueen was urgently called by her instructor to the laboratory for an experiment. Everyone saw her put a can of xylitol on the laboratory bench, and potassium cyanide was used in the experiment that day.The police found cyanide in her box of xylitol. As a precaution, other belongings were also checked, and there was no poison residue.

The only strange thing is that no xylitol was found at the scene or in her stomach.

However, after many investigations, Li Xueen's interpersonal relationship was simple, and there was no enemy who would kill her, and there was no sign of outsiders committing crimes. The most unusual thing that day was that she went to see Xia Lin.So Xia Lin was interrogated in turn that night, and didn't leave the Criminal Investigation Detachment until twelve o'clock in the evening.

Apparently, the police also thought it was illogical to be killed by the other party if it failed to show love. No xylitol was found in the stomach, and it was thought that it was thrown into a trash can at will.In order not to waste public resources, the case was quickly closed.

Behind all the hustle and bustle on Christmas Eve, a fresh life quietly disappeared in the deserted old playground.Due to the tinge of accidents, apart from the fact that the school held laboratory safety lectures throughout the school, this incident did not cause much sensation, and it only occupied a small section of the newspaper, becoming a topic of discussion after dinner. , and was replaced by fresher and more bizarre events in a very short period of time.Except for the witnesses and some people in the detective agency, no one is worried about it anymore.

Facts have proved that it is not a good idea to have a long talk on the roof in winter. Xia Lin was so cold that her hands and feet were almost numb, and only the woolen scarf around her neck was still doing her best to retain heat.He wished he could wrap his whole body in it.

"Li Xueen has a habit, I think you all know it," Xia Lin's voice trembled, "no matter what she eats, she will immediately eat a few xylitol slow flavor, she said she doesn't like other things The taste left in her mouth. When we met at the cafe that day, she ordered a cup of flat white coffee. Although I didn’t see it with my own eyes, I’m sure she would eat xylitol immediately after drinking the coffee. The police speculated that the time of death was 06 From one o'clock to ten o'clock, it only takes a few seconds for cyanide poisoning to attack. It is impossible for Li Xueen to drink a cup of coffee until after nine o'clock, and then go to the old playground to eat the poisonous xylitol - so when I met her in the cafe , Xylitol should not be poisoned yet, it is impossible to get the poison from the laboratory in the afternoon, but after I separated from me, that is, after 30:[-]. Therefore, this is absolutely impossible to be an accident. "

Liu Xiran pondered for a moment, then nodded: "I do know about Xue En's habit, but why do you suspect that the murderer is a member of the club? And you didn't tell the police about this suspicion?"

Xia Lin didn't answer but asked instead: "By the way, do you have any basis for suspecting that this was not an accident?"

"Ah?" Liu Xiran gave Xia Lin a silly look, and then said blankly, "No, let's intuit it."

Xia Lin glanced at her helplessly: "I seriously doubt that telling you this is useless at all, you two are not smart enough to be my partner"

Liu Xiran jumped up again and gave Xia Lin a slap: "Hurry up and say, I'll kill you!"

Apparently succumbing to Liu Xiran's lust, Xia Lin said in a bad tone: "I said it when I made the statement, but the police uncle said that I didn't see her eat xylitol after drinking coffee. It's a human habit. It's not absolute, seeing is not believing. After I called the police, I checked Li Xueen's mobile phone, and the last call log was me, and I didn't receive any text messages. Social software is also full of group messages. See you after she leaves the coffee shop The person in question is very likely to be the murderer, but no trace can be found through ordinary contact channels, but it does not rule out that she made a verbal appointment with him in advance, but if she didn't forcefully kiss me in the cafe that day, I might not lose it. Now she is leaving alone, so the possibility of a verbal appointment is unlikely..."

Liu Xiran immediately grasped the key points of the words: "What? You said she kissed you forcibly?" Zhao Yang quickly covered Liu Xiran's trouble-making mouth.

Xia Lin selectively ignored Liu Xiran, who was dancing around, and continued: "So I thought of a very strange thing when I met Li Xueen that day. Her phone turned on, and I saw a very abstract icon push, I didn't see the rest clearly, but there were the words 'society activities' in it. Li Xueen reacted strangely when she saw this post, showing a very weird expression. I agreed to associate with her, and then she said that I had a reason to associate with her, so she pecked me so confidently.

"I tried to start with this software to see if I could find traces of her contacting others. Later, I searched for a long time before I found that software, which was the brain-dead game 'Dead Movement'. The push was sent by a friend. News. I guess the murderer contacted her by using the social function of this game, and after meeting, the murderer poisoned her xylitol..."

Liu Xiran interrupted again: "Wait, wait, so, because the tweet mentioned the club, and it seems to be related to you, the only social circle you share with Xue En is the detective agency, so the murderer is People in the club. Since the murderer contacted her through the game, wouldn’t it be enough to just look at the chat records on everyone’s game? Why do you need to spend so much time playing team battles?”

Xia Lin gave Zhao Yang a look, and Zhao Yang blinked to express his understanding, and explained: "The murderer will definitely delete the chat history in order to eliminate the traces. I don't know if it can be restored through technical means. So Xia Lin and I made After doing an experiment, I deleted the chat history, and asked the master in the department to help me read it, but the master said that this game does not have the function of storing chat records. Even if the murderer does not delete it, we will not be able to find any traces. "

Xia Lin added: "So I plan to let everyone download the game and look for traces from it. By the way, you saw this game on Xu Luo's phone that day, which accelerated our plan. I was never in front of Xu Luo. Speaking of this game, I was also surprised that he played this game, which is one of the reasons why I doubt him. Since the murderer can use the social function of this game, then I can also use it. This so-called team battle is I prepared it especially for the murderer."

Liu Xiran hastily intervened and said, "I, I, I know, so the division of members into three groups was also arranged on purpose by you. You must have someone who is suspicious, tell me."

Xia Lin smiled: "It seems that you are not as stupid as I imagined. First of all, of course, start with the alibi. The two girls in the third group are poisoned patients in Moments. They have been posting and watching performances in Moments on Christmas. The show lasted until twelve o'clock. The other one is addicted to online games, and the owner of the Internet cafe knows him very well, so you can find out just by asking. After I separated from Li Xueen, I went to eat hot pot with Zhao Yang and the others in the dormitory , until I found the body when I came back. I also knew your alibi just now, so there are only three people left: Xu Luo, Qin Yuhang, and Wei Ziyi. All three of them have alibi, which happens to be a little strange place.

"Let's talk about Qin Yuhang first. She is very beautiful, and she is very considerate in the club, especially to me. She was a freshman in the Department of Fine Arts and joined the club for three months. Li Xueen was a senior in the Department of Chemistry and joined the club for at least three years. Qin Yuhang joined the club for at least three years. At that time, Li Xueen was preparing for the postgraduate entrance examination, and the two of them should have only met a few times, and they behaved strangely to each other. At first glance, these two people have no intersection, but they should have known each other for a long time. I found such a photo in her album."

Xia Lin handed the mobile phone to Liu Xiran. On the screen of the mobile phone, a girl in a white dress stood in the middle of the road, with a youthful smile on her face, holding a rabbit doll in her hand. The background looked like Chengda’s dormitory building .

Liu Xiran didn't take it seriously: "Isn't this Qin Yuhang, what can you tell?"

Xia Lin pointed to the corner of the screen: "What do you think this is?"

Liu Xiran zoomed in on the photo, scanned the phone screen with wide eyes, and exclaimed incoherently: "This back! Blue hair, sister Xue En's hair! This blue must be her!"

Xia Lin reached out her paw and touched her head: "That's right."

Liu Xiran suddenly thought of something, and unconsciously clenched the phone tightly: "Wait, I remember, when Sister Xue En dyed this color, it seemed to be in her junior year, and then changed to brown or gold, Qin Yuhang He probably hasn't entered school yet. But, that doesn't mean anything, maybe Qin Yuhang Laicheng took this photo, and sister Xue En just happened to be in the picture, it's just a coincidence."

Xia Lin took out the phone from Liu Xiran's hand: "Of course this possibility is not ruled out, but when you look at the photos, can you pay more attention to the details? The rabbit in her arms is exactly the same as the one hanging on Li Xueen's bag. It was still on until the day of the accident. It’s so obvious that you didn’t see it, are you blind?”

Liu Xiran muttered softly, "He didn't date me again."

"Look at the time watermark in the corner. It was June last year. At that time, Qin Yuhang was indeed not a freshman, so I said that they had known each other for a long time, but when they met again later, they pretended not to know each other. I had to think wrong. That day Qin Yuhang asked me to watch the performance, but I refused. Later, she went with her roommates. I inquired about it, and because there were too many people, several people got separated. In short, she did not have a clear alibi, and she and Something must have happened between Li Xueen, and this may be her motive for killing."

Zhao Yang nodded: "Yes, I also vaguely feel that the two of them are not like the first time they met. Sister Xue En seems to always look a little dodgy when she looks at Qin Yuhang."

Xia Lin went on to say: "Let's talk about the second suspect, Wei Ziyi. Li Xueen's direct junior in the Department of Chemistry, Li Xueen was also tricked into this Sunset Club by Li Xueen. The locals are often not in the dormitory. I pretended to ask casually. How did he spend Christmas as a single dog? He reported his whereabouts as if he was reciting lines. He returned home after finishing the experiment in the afternoon. There was no one at home. He cooked alone and watched TV. He also gave me the variety show he was watching. I told it once—I can guarantee that it was the most he talked to me. He said that his favorite artist AGE was on the show that day. Later, I changed the wallpaper of my mobile phone to AGE’s life photos and showed him, and asked him Well, he actually said, 'Very beautiful, your girlfriend?', I think that is suspicious enough, who would have prepared an alibi in advance? I think it is not the murderer but also someone connected.

"Wei Ziyi is low-key, has a low sense of existence, and has few friends. Even if he sneaks back to the school secretly, no one will notice. He was also present when Li Xueen was doing the experiment in the afternoon. He can definitely come into contact with cyanide. Remember the brand of Li Xueen's xylitol, buy another one that is exactly the same, apply poison, and trick Li Xueen out to find a chance to replace it. The operation is simple, convenient and fast, and there is no one more suitable to be a murderer than him. As for the motive... "

Liu Xiran suddenly cleared his throat, deliberately lowered his voice and said, "I, Holmoran, may know."

She paused for a moment, and Zhao Yang asked cooperatively, "Da Ran, what do you see?"

Only then did Liu Xiran put on a posture and said slowly: "Well, with a woman's sixth sense, I think Wei Ziyi likes Sister Xue En, but he can't get it, so this may be love killing."

Xia Lin lifted her chin and looked at her: "Are you finished?"

Liu Xiran nodded obediently.
