"Nope! I didn't kill anyone! Park Eun-sun's chest rose and fell violently, "This is clearly someone who wants to blame me!" In order to clear the suspicion of murder, after Park Eun-sun was taken to the police station, she recounted the dinner with Jang C at the café in 1510: "After parking in front of the café, I also brought a pair of big sunglasses to avoid people's eyes. That bottle of French dry red wine was brought from home. The time when the two of us walked into the café happened to be half past nine, and as soon as we sat down, Director Zhang said with a spring breeze on his face, baby, what to eat. I replied nonchalantly to eat you. Director Zhang laughed and said that I really ate you in my life. (The melodious piano music in the café sets off the ambiguity, the half-red candle of the goblet on the coffee table slowly flows with thick candle tears, and the Valois milk coffee in front of it is filled with a rich fragrance.) Director Zhang looked at me stupidly, his eyes fell on my plump and fair breasts, I like men to look at me like this, the more he looks at me like this, the more I feel proud to be a woman, so I give him a teasing smile. He could see God. It wasn't until the waiter prompted Mr. to order something that Director Zhang withdrew his gaze from me. We casually ordered two steaks and roast beef. Director Zhang looked very excited, he took my hand and said, "Baby, I have a big surprise to tell you." I said, you just want to tell me that I am the winner of the Newcomer Award at the next TV Festival. Director Zhang smiled, his mouth was like a cracked walnut, and he innocently rubbed some orange juice with his fingers and wrote on the white tablecloth. I said what are you doing? He pointed to the table and showed me, it was "Iloveyou", I smiled and said, come on, you, it's so vulgar, it's this age. Who knew that he patted his chest unconvinced, and said very seriously, baby, am I really old? Just then, the waiter served. ”

"How many times has the waiter been here? How long did you stay? Have you both eaten the dish? Cha Min asked.

"Just once, he left immediately after serving the food, and in less than 1 minute before and after, we both ate the dishes." Park Eun-sun recalled: "I was eating steak, he took out the divorce certificate from his pocket and slapped it on the table, saying, baby, I fulfilled my promise, I am divorced, marry me, I will make your star journey more brilliant." I thought he was joking with me, saying, you don't come to this set, and you got a fake divorce certificate to fool me. Who knew that he actually swore a poisonous oath, saying that if this certificate was fake, all the eighteen generations of my Zhang family were turtle grandsons. I looked at his serious expression, frightened, I didn't expect him to take what I said on a whim seriously, just when I was in a dilemma, my mobile phone rang, the signal of the seat in the café was not very good, I rushed to the balcony to answer the phone as if I had been amnesty. As soon as I stepped out of the balcony, a black shadow jumped out of the balcony and grabbed my wrist. I fixed my mind that the man was Gu Zizhe. He wanted to come and hug me, and I said you let go, and if you don't let go, I'll call someone. He gritted his teeth and said, I finally caught you, you shouted, aren't you just with that old man? I already knew that you had a bad affair with that old man, didn't you hook up with that old man just to play the heroine? I glared and said, what are you talking nonsense, you. He still grabbed my wrist and said more vigorously like a firecracker, he said, don't think I don't know, you are hooking up with a more powerful backer now, and the producer Kim Jae-won Rong has set his sights on you. You wanted to dump that old man, and for you, he was no longer useful. But that old man actually proposed to you just now, you played with fire, and you still don't take me seriously...... Gu Zizhe said, Director Zhang stood behind him silently, and when Gu Zizhe turned around, his face turned blue with fright. After that, they both held back and did not speak, like bulls with two horns, with fire in their eyes. ”

"How did you feel?" Che Min asked.

"Cool!" Park Eun-sun lifted Erlang's legs, raised his eyebrows, and showed a smug and satisfied expression, "I like men to fight for me, and I like men to fight for me in front of me." ”

"And then?"

Director Zhang's eyes were so red that he asked me, it turned out that he didn't agree to my marriage proposal because of this stinky boy? I was busy saying no. Zhang directed Gu Zizhe and yelled at Gu Zizhe that I am going to kill you, this shit, and picked up a pot of flowers on the balcony and threw it at him. Gu Zizhe flashed quickly, and the flower fell down with a "bang". Everyone in the crew knows Director Zhang's temper, and he can do anything on impulse. Gu Zizhe was probably afraid that things would make a big fuss, so he left stupidly. Director Zhang and I stood on the balcony for a moment, I comforted him a few words, and then we sat back at the dining table. It's about 10:05. After Gu Zizhe made such a fuss, both of us were not in a good mood, bowed their heads and ate separately, and did not speak. Afterward...... Later, Director Zhang covered his chest and said that he was uncomfortable, and he broke out in a cold sweat, and then something happened......" Cha Min listened to Park Eun-sun's narration and pondered: In which link did the poisoning appear?

Outside the window, the night is deep, the stars are heavy, and the hustle and bustle of the city is blended into the thick inky night. Ko Se-yeon interrogated the waiter who had been in contact with Park Jung-cheol and Jang C overnight, and his suspicion was ruled out.

Che Min and Gao Shiyan returned to the criminal investigation office to discuss the case, Gao Shiyan fiddled with a matchbox-like black box hidden in the cushion recovered from the scene and was stunned, frowning and asking Che Min: "What is this?" ”

"Let's talk about the results of the handwriting examination first." Cha Min shrugged with a wry smile.

"Yes. The note was indeed written by C. Moreover, in Zhang C's pocket, some nail chips were also found, whose nail is it? Why is it in his pocket? Gao Shiyan frowned thoughtfully, "Alas, then again, a big director was fascinated by a woman, and even his life was put into it." We women are really not easy to mess with. Gao Shiyan frowned and sighed. At this moment, I saw the forensic doctor standing behind her quietly, and suddenly slapped Gao Shiyan's shoulder with a "snap", which frightened Gao Shiyan into a spirit, turned her head, and saw the forensic doctor's apricot eyes round, and shouted: "That's right." It's really hard to mess with, say me! ”

"Oh, it's not you, spare me, sister." Gao Shiyan is well versed in Han Caiyan's hot and straightforward temper, clasped her hands into fists, shrunk her shoulders, and made a little monkey spirit begging for mercy. Han Caiyan was amused by Gao Shiyan's cute expression, laughed out loud, and said, "I'm here to deliver the autopsy report, I have a chance to clean you up, I'm not in a hurry yet." ”

"Well, let's talk about the results of the autopsy first." Che Min said.

"I extracted Zhang C's gastric juice analysis, and Zhang C died of high concentrations of cardiac glycoside poisoning. The symptoms of cardiac glycoside poisoning are similar to heart attacks, with uncomfortable pressure in the chest, swelling or cramping, as well as dizziness, cold sweats, and shortness of breath. This is similar to the situation described by Park Eun-sun. Judging from the contents of the stomach, Zhang C had eaten mutton, beef, mushrooms, orange juice, and wine before his death. Cardiac glycosides are extracted from orange juice, which indicates that the poison is in the orange juice. And judging from the degree of decay and digestion of the stomach melt, Zhang C died less than ten minutes after eating these things. This reaffirms my assumption about the time of his death: between 10 and 10:40. A cold wind blew, and Han Caiyan sneezed loudly.

"Ahh Che Min took off his coat and put it on Han Caiyan, "The toxicity of cardiac glycosides is classified as Class 6 in the United States, which is a highly toxic substance similar to XXX and potassium cyanate. High concentrations of cardiac glycosides can cause death within 15 minutes. Since the poison comes from the mouth, the problem must be in the food, especially the bottle of orange juice. ”

"Ahem," Han Caiyan has always been straightforward, but now she wrinkled her eyebrows into a figure of eight, sighed faintly, and said: "Coffee, orange juice, mutton, beef, and everything brought back from the scene, as long as it can be eaten, I have tested it, and the cardiac glycosides have all tested negative." ”

"Ahh Gao Shiyan exaggerated her mouth into an "O" shape, and said in surprise, "This is strange, why is the orange juice in Zhang C poisonous, but the orange juice on the table is not?" ”

"Yes!" Che Min slapped his desk, "This is the incredible suspicion in the case." What is certain is that Zhang C was poisoned by eating food containing cardiac glycosides, and no matter what kind of food the murderer poisoned, he could achieve his goal. However, why were cardiac glycosides not found in the food retrieved from the scene? How did the murderer erase the evidence of the crime? ”

"Could it be that the murderer didn't put the poison in the food at all?" Gao Shiyan asked thoughtfully.

"Ah, you mean, Zhang Cji took the poison directly?" Cha Min said along Gao Shiyan's train of thought.

"Suicide?" Han Caiyan slammed her desk excitedly, "What reason does he have to commit suicide?" And committed suicide in front of Park Eun-sun, blamed her, and had to pull a cushion when he died? ”

"No, no, no," Cha Min said, shaking her head, "and it can't be concluded as suicide yet." Then Cha Min took out a blank piece of paper from his desk, wrote down the three names "Park Eun-sun, Jang C, and Goo Ji-cheol", and said, "Aside from the suspicion just now, these three people have the motive and timing to commit the crime. Solving a case often requires divergent thinking, and if we can't break through from the key points, we can be shortlisted from the edge. Human beings are animals governed by the will, so analyzing the criminal mind is a good way to see through the truth. ”

"Hey, what do you want to say?" Han Caiyan was confused.

Cha Min smiled, pointed her finger at "Park Eun-sun", and said: "From the analysis of her words, she doesn't love these two men at all, and the reason why she seduces Jang C is to take advantage of his power, as for Gu Zi-cheol, it is out of a kind of woman's vanity, or a cynical attitude, playing with men's feelings, and using men as a stepping stone for her to achieve her goals, so she naturally will not be willing to commit to any man." And Zhang C's divorce scared her, so in order to get rid of Zhang C's entanglement, she poisoned him. Then Che Min pointed his finger at "Zhang C" and said,

He actually hated Park Eun-sun, hated her for using the power in his hands, and hated her for playing with his feelings. At the same time, Zhang C also loves this woman, and he is reluctant to let other men get her. Therefore, he even did not hesitate to poison himself at the cost of his life and blame Park Eun-sun. As for why Gu Zizhe was poisoned, I don't need to explain. Che Min frowned, figuring out the psychology of the three parties.

"Ahh Han Caiyan's eyes flashed, "As soon as you say that, they all become suspects?" ”

"Yes." Che Min's eyes swept over the desk, his eyes fixed on the small box recovered from the scene, and suddenly realized, "This is a very premeditated poisoning." Che Min suddenly changed his words and asked, "If you are the person concerned, if you receive a mobile phone and the signal at the café is not good, what will you do?" ”

"I'm going to pick it up somewhere else. Just take a few steps. Forensic doctor Han Chae-yeon blurted out.

"Yes." Cha Min nodded, "Park Eun-sun did the same." She went to the balcony to pick up the mobile phone, and the signal on the café was not very good, it was not accidental, it was this small box that was causing trouble. This small box is called a cell phone signal blocker. ”

"Ahh The forensic doctor suddenly realized, "You mean, Zhang C deliberately hid this thing in the seat, and then secretly ordered someone to call Park Eun-sun's mobile phone, in order to break her up!" ”

"No!" Cha Min shook his head and said, "Someone is deliberately hiding this thing in order to distract someone." ”

The words "someone", "deliberately" and "someone" are the key words.

"Someone" - who is it?

"Deliberately" to separate one of them, but who is "someone"? Unraveling these three questions brings us closer to the truth. Cha Min went through the question twice in his mind: Why, one person present? Naturally, it is for poisoning not to be detected.

Then there will be two conclusions: First, the poisoning happened in the café and it was a certain moment when Park Eun-sun or Jang C left their seats. Second, since the poisoning occurred at a certain moment when someone left their seat, but no source of poison was detected at the table, then the murderer must have used some method to erase the traces of the poison after the poisoning, and since the erasure of the traces occurred after the poisoning, and the onset of cardiac glycosides was instantaneous (this is similar to qi

ghuajia), then Zhang C, who has been poisoned, has no ability to erase the traces of poisoning, thus ruling out the possibility of suicide. So, who is the murderer? (It's possible that Park Eun-sun lied.) What methods were used to erase the traces of sin? Cha Min told Ko Se-yeon and Han Chae-yeon about her thoughts.

Gao Shiyan fiddled with the office to catch the objects retrieved from the scene, and suddenly found that her eyes lit up like a new world, and she screamed, and handed the wine cork to Che Min, who looked at it carefully, and there was a slightly concave hole on the end of the cork full of micropores, which was very different from what she naturally generated. On the reverse side, there is a slightly raised hole, the two can be connected into a line, those two small holes, like the entrance and exit of a gunshot, the line, just like - Che Min suddenly remembered a scene from a certain movie - the flamboyant bar girl took advantage of the customer's inattention, pierced the syringe barrel into the wine cork, and quickly injected poison. Yes! Could it be that this is the method used to poison the poison? Just when Che Min was thinking about it, Gao Shiyan called out to Che Min: "What do you want?" So distracted. I'm going to tell you another point of doubt about the case. ”

"What's the doubt?" Cha Min came back to his senses.

"You see, the two coffee cups brought back from the scene have the fingerprints of Park Eun-sun and Jang C, and the two cups have another person's fingerprints on them. Although I don't know who this person is, it also makes people feel strange: Park Eun-sun and Jang C each drink their own coffee, but why do fingerprints appear on each other's coffee cups? And who touched their coffee and left their fingerprints on their coffee cups? What is the purpose? Gao Shiyan asked with a frown.

"There are so many suspicious points in this case!" Forensic doctor Han Chae-yeon said.

Che Min smiled weirdly and said, "Visit the insiders, and break them all!" ”
