Li Mu was a little surprised, but also felt lucky.
Many times, if there is no evidence, then look for some abnormal events. Abnormal events are often where the evidence lies.
"Walk!"
Li Mu said that when he arrived in a courtyard, he saw a maid lying on the ground, dead. On the table next to her, there was a bowl with soup in it.
"But he was poisoned!" Li Mu asked.
"No!" Qian Xiucai said. He took out the silver needle and pierced Xiaocui's body. The result was that the silver needle did not turn black. He also pierced it into the soup, but it still did not turn black.
Qian Xiucai said: "Xiao Cui was not poisoned, but died of acute illness!"
Acute disease is heart disease.
Li Mu shook his head and said: "Some poisons cannot be detected with a silver needle!"
First, the silver needle test for poison has certain accuracy.
After all, in this era, the main poison was arsenic. If poisoned by arsenic, the silver needle would turn black.
But from another perspective, it is inaccurate.
For example, the arsenic in this era is impure and contains sulfide, and a silver needle will turn black when placed in it. But if the arsenic is pure enough, the silver needle will not turn black if placed in it. There are also some foods that contain sulfides.
If a silver needle is inserted into it, it will turn black. For example, if a silver needle is inserted into an egg yolk, it will turn black.
There are also many toxins, and the silver needle will not turn black if you put it in it.
"Actually, to check whether it is poisonous or not, it is best to use a white mouse. If you don't have a white mouse, a puppy will do!" said Li Mu.
After a while, a puppy was brought in and the remaining soup was fed to the puppy.
After a while, the puppy foamed at the mouth and fell to the ground.
Li Mu stepped forward and inspected Xiaocui's body. His body was still hot and he had not died for a long time. He stepped forward and smelled the smell in the bowl and said, "This is ricin!"
"Now that the case has reached this point, everything is actually clear!"
Li Mu said: "Gather everyone in the Qian family and go to the living room for a while. Secretary Wang is taking notes!"
"Yes, sir!"
After a while, dozens of people from the Qian family gathered together.
The Qian family is a big family, with three sons and two daughters. The eldest son, Qian Ming, is an official in another place; the second son, Qian Lai, is doing business in another place; the third son, Qian Zao, is also Qian Xiucai. The third son successively
He married a wife and had children. He also had two daughters who got married one after another. The daughters who got married seemed to get water after pouring it out, so it’s okay not to talk about it!
Qian Juren, named Qian Sun, is over fifty years old. He has an old wife and three concubines at home.
In addition, there are maids, slaves, etc., about twenty-eight people.
Looking at the Qian family, Li Mu kept observing. In his eyes, anyone could be a criminal.
The Qian family had already gathered together. Li Mu looked up and down and said nothing for a long time. Everyone was worried and didn't know what the elder was going to say.
"I, Li Mu, used to be a detective, but today I am a county magistrate. I don't seek a prosperous official career, but seek peace in the world! Now that the case has come to an end, the murderer has been revealed!" Li Mu said, "I am now deciding the case. You guys
Is it acceptable?"
"My lord has decided the case, so I'm naturally convinced!"
Everyone said in unison.
Li Mu was very satisfied. In today's era, there are no so-called unruly people, and the number of unruly people is also very small.
"Qian Juren died. The cause of death was initially determined to be robbery and homicide. However, after the initial identification, I found that it was a disguise. Because it was just theft, there was no need to kill. Various traces inside also proved that Qian Juren was murdered.
Killing is a vendetta! As for the cause of death, the initial cause of death was poisoning, that is, death from arsenic poisoning; but later it was determined that the death was due to a broken throat; and the final identification revealed that the real cause of death was death from ricin poisoning!"
Qian Xiucai said: "Sir, what is ricin?"
Li Mu said leisurely: "Ricin is a medicinal material that can be used to treat diseases. However, the medicine is three-thirds poisonous. The toxicity is more severe than arsenic. It is colorless and odorless. After poisoning, the toxicity explodes quickly and there is almost no cure. After poisoning
Testing showed no sign of poisoning at all!"
"It's just like most wealthy people use silver bowls or use silver needles before eating to test whether the food is poisonous... You can put ricin in it, but the silver needle can't detect it!"
The crowd was in an uproar.
"Recently, Xiaocui has been taking medicine abnormally. The medicine is mainly used to treat sore throat and purgative stagnation. One of the medicines is castor seeds. Castor seeds alone have limited toxicity. They can be purified in large quantities, but they are highly toxic.
!" Li Mu said: "Originally, I came to Qian's house to ask why Xiaocui took medicine!"
"But now, Xiaocui is dead. She died of ricin poison. The soup she just drank contained ricin poison! Can you tell me why this is?"
Li Mu shouted, staring at everyone present.
Everyone has different expressions, some are fearful, some are terrified, some are frightened, some are uneasy, there are thousands of people with thousands of faces, and all kinds of expressions are on display.
Suddenly, Li Mu thought of "The Last Supper", and a few more suspects appeared.
Li Mu continued: "In the past six months, has anyone gotten sick or had a sore throat?"
The eldest daughter-in-law of the Qian family said: "In the past six months, only the third child has had a sore throat, and everyone knows about it!"
The second daughter-in-law of the Qian family said: "Everyone knows that Xiaocui is the third daughter-in-law!"
"If it's not the third child, then who is it?" The second lady said, "My parents happened to come to investigate the case. Xiao Cui is suspected, but Xiao Cui happened to be dead. Who is the third child if it's not the third child?"
The third lady said: "Third brother, the old man treats you well, why do you want to kill your father?"
Everyone is making accusations, and all the unfavorable evidence points to Qian Xiucai.
Qian Xiucai immediately turned pale and said with fear, "I didn't kill my father, didn't I?"
The fourth lady said: "If it's not you, then who is it? You are guilty of being a thief. If you are not guilty, why are your face pale and why are your hands trembling?"
Qian Xiucai said: "Sun Jiachen of the Sun family is the murderer of my father and so on, but I am not. Sun Jiachen has already confessed, but the Miss Sun family went to the county government and gave money, so you let him go, but you were wronged."
Me? I’m not convinced, I’m not convinced!”
“If you don’t accept it, you have to accept it!”
Li Mu sneered and said: "Miss Sun's family did come to the door to plead for mercy. I just said that I will not let a bad person go, nor will I wrongly accuse a good person, that's all. As for the evidence, if you want evidence, I will give it to you.
evidence!"
"Does anyone in the Qian family have a dog?" Li Mu asked.
The second lady said: "Yes, the Qian family has four dogs to look after the house and the courtyard!"
Li Mu said: "If a bandit enters the Qian family, the dog will be poisoned to death. Otherwise, the dog will bark and be exposed. But have the Qian family's dogs been drugged to death?"
The second lady said: "No, the four domestic dogs are fine!"
Li Mu said: "This also proves that it was not the work of outside thieves, but the work of internal thieves. Because dogs will not bark when they encounter internal thieves. Just this one is to wash away the grievances of the Sun family. And once again
It has been proved that the murderer was committed by someone within the Qian family. As for Xiao Cui’s death, it also proves this. Is what I said reasonable?”
Everyone said in unison, "Your Majesty, what you said makes sense!"
Secretary Wang wrote the nominations very quickly and accurately.
"The murderer who killed Qian Juren must be the Qian family?" Li Mu shouted: "You are the only suspect. As for the others, was it the second lady, the third lady, or the fourth lady? They had no motive for the murder, and they had no intention of committing the crime.
For all the reasons, you are the most suspicious!"
