"Ouyang, based on the signs of poisoning you provided, I preliminarily judged that the victim was poisoned by a fungus called the Deadly White Poison Umbrella."

I stared at this line of WeChat messages and replied: "From the first day of the victim's vomiting and diarrhea, to the second day's 'false recovery', and finally the death of severe liver failure, it is indeed consistent with the poisoning symptoms of the deadly white poison umbrella." But there is a bit of a counterintuitive, if the victim is poisoned by a lethal white poison umbrella, then she must ingest more than 50 grams of deadly white poison umbrella. With such a large dose, it must be taken as an ordinary edible fungus for the deadly white poison umbrella. However, according to my investigation, the deceased's diet three days ago was all takeaway ordered with circus members, and there were no mushrooms or mushrooms in the takeaway they ordered. Because these three days were rehearsals, the victim did not go out to eat alone, which can be confirmed by her boyfriend and girlfriends. ”

The message sounded, and there was a new reply: "Perhaps through professional concentration technology, the poisoner made the deadly white poison umbrella into powder or reagent, but this is purely my conjecture." ”

"Is there such a concentrating technology in today's technology?"

"It's easy to do."

"Thank you! You helped me find a big breakthrough. ”

The person I spoke to on WeChat was a professor at the China Academy of Chinese Medical Sciences.

As I said before, I don't have more than 30 contacts on WeChat, and 26 of them are not ordinary people. They are all experts in various scientific fields in China, and it can be said that they are my WeChat think tank. Perhaps it is a coincidence that 26 is an important breakthrough in numerical reasoning, and its addition or subtraction of 1 is the cube of 3 or the square of 5, and the appearance of almost 26 means a quick solution to a problem. Therefore, when I encounter some professional problems in the investigation, I will come to them for advice, and the answers they give can often make me break through in the mystery.

The answer given to me by the professor made me simplify the modus operandi of the poisoner, and now I will sort it out. In the first step, the poisoner kills Uncle Mao, the clown; The second step is to register as a clown actor in the Wonder Entertainment Company, and successfully infiltrate the Hongyang Circus with low salary and self-recommendation; The third step is to approach Yang Shiruo during the rehearsal and use a concentrated lethal white poison umbrella poison to mix it into Yang Shiruo's food or drinking water, and eventually cause her death. As for why the killer clown didn't leave the circus immediately after the successful poisoning, I think this is the self-confidence of professional killers and the mentality of playing the game of death.

The question of how to administer poison is solved, but the two more important questions are, who administers the poison? Why poison? But I was confused.

Looking at the calendar, it will be the Chinese New Year's Eve in less than a week, but my mood at this time does not feel warm or festive because the year has come. On the contrary, because of this bizarre case, sometimes excited, sometimes frustrated. Excited, because of bizarre and weird, frustrated, because I can't figure it out.

In the past two days, I have been going back and forth between the criminal investigation team, the circus and my home, and I feel a little exhausted, but there is not much progress in the case. Even if suspicious footprints are found at the scene of the crime in the big bamboo forest, it is difficult to identify the owner of the footprints.

I once proposed to compare this footprint with the footprints left by the 'Demon Slayer' on the outer wall of the criminal investigation team, but it was denied by Wang Pengdiao, a footprint expert, because the footprints on the wall were not left by normal walking, and the various stress points on the footprints were completely abnormal, even if the footprints on the scene of the big bamboo forest and the footprints on the wall were left by the same person, it would not be possible to make a correct judgment.

As soon as the man was depressed, he increased his cigarettes and alcohol. In the evening, I asked Lao Lu and Tang Zhenguo to go to the vegetable farmer's fragrant skewer restaurant to drink.

The red oil is rolling, and the bamboo skewers have been bundled. After three rounds of this wine, Lao Lu's words gradually increased, and I saw him blushing, squinting and saying: "As soon as the pass arrives this year, the big and small banquets run one after another, either on the way to the banquet or on the way to the banquet." These days feel like being soaked in a wine jar, but these successive big cases can't be solved, and the wine soaked in the wine jar is also bitter wine, and it's not interesting to drink. ”

I took a sip of wine and said, "Old Lu, since the last Bell Tower murder case, I have felt uneasy, and I feel that behind this case, there is always some special force pulling behind. The killing of the prisoners detained in the bureau was obviously committed by a criminal gang, which is entrenched in Wanzhou, and I think you have had a bad year. ”

"Hey, go and go, which pot is not opened. Today, we will drink and say goodbye (chat) and gossip, and stop talking about work. ”

I smiled and said, "Okay, drink and gossip." Speaking of gossip, I really have one here, and I found out that Xiao Xia's kid is in love. ”

As soon as I said this, Lao Lu put the wine glass on the table and said loudly: "Don't mention this, I'll be angry when I mention this, and today I asked him to reflect on this matter, do you know who his girlfriend is?" It was the junior who died Qin Wenyuan used to raise, Lu Meilin. I asked him to investigate Lu Meilin, this kid is good, he has a deal with the subject of the investigation, don't you say he's fooling around? ”

I took a bite of the beef and said, "Don't fool around, don't fool around, don't you see that the killer is also in love with his assassination target?" ”

Lao Lu drank all the wine in the cup in one gulp and said, "Red face and bad water." Xiao Xia, this kid will be planted in the hands of that woman sooner or later. ”

Whether it's a red face or a red face, I just broke it out during the banquet, and then laughed it off, as for whether Xiao Xia and the woman's future road is a disaster or a blessing, who can say clearly?

At this time, Tang Zhenguo, who had been drinking and looking at his mobile phone, suddenly said: "This Feng Xiaoke really looks like Yang Shiruo." ”

I wrapped a mouthful of leeks in my mouth and said, "Who is Feng Xiaoke?" ”

Tang Zhenguo said: "Feng Xiaoke is the third daughter of the great writer Feng Yu. ”

Lao Lu said: "Oh, I know, Feng Yucai, who lived in seclusion in Wanzhou, passed away, saying that he left an inheritance of two billion, and most of his three children are going to stage the old bridge of the battle for the inheritance of the wealthy family." ”

I said, "Yes! Show me the picture of Feng Xiaoke. ”

Tang Zhenguo handed me the phone, and I looked at the pictures on the phone. Indeed, it is too similar to Yang Shiruo, almost identical. So I quipped, "Hey, hey." This Yang Shiruo is actually the abandoned baby of a wealthy family, she is Feng Xiaoke's twin sister, the fourth child of the great writer Feng Yu. ”

Tang Zhenguo stared at me with big eyes and asked with a look of surprise: "Ah! It's true? ”

"Fake!"

Lao Lu raised the corners of his lips disdainfully, stuffed a mouthful of pickled pepper beef into his mouth and said, "You have watched too many bloody dramas!" ”

In fact, I never watch bloody dramas, just drink and break a sentence. However, there are some things that cannot be said nonsense, and it is likely that they will become 'prophecy'.

The next morning, I received a call from Lao Lu, who hurriedly said: "The eldest son of the great writer Feng Yu died in Feng Yu's villa last night. ”

Lao Lu led the team to the scene of the crime early in the morning, and Xiao Xia was still ordered to come to pick me up and Tang Zhenguo, and the destination was Dayakou Forest Park.

Dayakou is 22 kilometers away from Wanzhou urban area, 60 kilometers away from Kaizhou urban area, spanning Wanzhou and Kaizhou boundaries, with an altitude of 1308 meters, which is the second highest peak on the north bank of Wanzhou District. The forest area is endless, the cliffs are steep and deep, the strange peaks are towering and green, the clouds and smoke float, the mountain springs are luscious, and the forests are luxuriant. The total area of the forest park is 350 hectares. The forests are dominated by Masson pine, cedar, metasequoia, marsh pine, torch pine, silver sugar maple and cedar. The average annual temperature is 15 degrees, and the frost-free period is 240 days. Summer is a cool summer resort, and winter is a good place to enjoy the snow in the snow forest. But at this moment, it is shrouded in a shadow of death.

At 11 o'clock in the morning, we arrived at Feng Yu's villa before his death, and as soon as we got off the car, we saw a plaque with a border hanging on the gate of the exquisite fence, which was engraved with two big characters of 'Feng Zhuang', which was strong and shining.

At this time, in front of 'Fengzhuang', except for two private cars, the rest were police cars, and the police cars pressed the ground mottled and ugly.

Across the fence, there is a small courtyard with a pavilion, and there is still some residual snow on the branches of the small courtyard, I think if it snowed heavily last night, this small courtyard must have some artistic conception, but after thinking about it, if it snows heavily, it is estimated that it will also bring a lot of inconvenience to the detection. Walking through the road in the middle of the small courtyard, I found some footprints, so I asked Tang Zhenguo to bypass these footprints and not to destroy them. When I entered the villa, I had no intention of admiring the antique atmosphere of the villa anymore, because a male corpse was lying in the center of the hall.

The investigation of the crime scene had long since ended, and Lao Lu stood next to a large vase with a phoenix printed on it and said, "The deceased died about 10 hours ago. His name is Feng Chicheng, 175 cm tall, 37 years old, Feng Yu's eldest son, American nationality, only returned to China a month ago, it is estimated that it is because Old Man Feng is dying, and he returned to China to prepare for the future. ”

"How did you find the dead?"

"The housekeeper of the villa called the police."

"Where's the butler?"

"In the police car outside, Xiao Liu was making a scene record."

I nodded, put on my gloves and looked around the corpse.

The fatal wound of the deceased was in the back of the head, there was a wound about two centimeters long, and the blood had coagulated, but it could be seen that the cut of the wound was very neat, and it should have been a person who used a sharp dagger from behind the deceased to stab the deceased into the back of the head with a very fast hand and then pulled it out.

I looked up and asked, "Have you found the murder weapon?" ”

Lao Lu shook his head.

I said, "Have the footprints outside been surveyed?" ”

Lao Lu shook his head again: "There are no suspicious footprints in the courtyard outside except for the footprints of the deceased and the housekeeper. And you can also see in the house, the deceased was wearing shoe covers, so the murderer may also be wearing shoe covers. ”

It seems that the murderer's modus operandi is very cautious, and he can only return to the corpse to see if he can find some clues from the corpse. The blood flowing from the wound was not disturbed, and there were no blood stains on the hands of the deceased, indicating that the deceased did not struggle and was fatally hit by a blow. Looking around the corpse, there are some splatters of blood, which is strange, if the murderer applies a knife from behind the deceased, then the splattered blood droplets should stick to the murderer, but not to the surroundings.

I stood up and asked Tang Zhenguo behind me, "If you are given a sharp dagger, can you pierce the back of a person's head with a single blow in the form of a flying knife?" ”

Tang Zhenguo said: "I once stabbed an adult bull in the forehead 10 meters away, and the bull was killed instantly. ”

I nodded and said to Lao Lu: "In this way, Feng Chicheng was killed by a flying knife. ”
