Song Ci didn't speak, he knew that He Jin's inference had some truth, and the conventional inference was indeed the case, Qin Xiaoyue was suspicious, but it didn't mean that Zhao Wu was killed by him.

A few people returned to the yamen from the melon shop, and Song Ci and the three of them entered the house, and Wenwu said: "My lord, I don't know how much you know about this matter?" The prisoner Qin Xiaoyue, is she really a murderer?"

Song Ci shook her head, all the evidence pointed to Qin Xiaoyue, which was very unfavorable to her.

"Two head catchers, I believe that Qin Xiaoyue is innocent in this matter, but I don't, or I haven't found enough evidence to prove her innocence, and now there is no third-party witness, Qin Xiaoyue is indeed the most suspicious, by the way, Wen Cheng, you go and ask He Jin for Qin Xiaoyue's address, and Song wants to go to her house to ask her old mother."

"Yes!" Wen Cheng walked out.

Wenwu poured Song Ci a cup of tea, "My lord, why don't we just start with the autopsy?" Chances are, the case wasn't poisoning!"

Song Ci shook his head, "Wenwu catches the head, it's not the time for an autopsy, maybe there is no need for an autopsy, the truth we have to find now is how to prove that Qin Xiaoyue was not poisoned, by the way, you have all the arsenic and the water bowl!"

"Take it, my lord explains, how dare we not be serious?"

Wen Cheng quickly got the information and walked out, "My lord, this is Qin Xiaoyue's home address, let's go over now?"

"Right now, we're running out for time."

The three of them walked out of the door, walked along the address, about half an hour later, came to a dilapidated earthen house on the edge of the county seat, the wooden door was not locked, Song Ci pushed it open, and the first thing I saw was the old woman sitting in the middle of the yard crying, and there was a shroud next to her.

Hearing the movement, the old woman turned around and looked, as soon as she saw Song Ci and the others, she knelt on the ground suddenly, "Lord Detective, the little girl is wronged, she didn't kill anyone at all, why did the yamen lock her up and cut off her head?"

Song Ci hurriedly helped her up, "Old mother, let's get up and sit down and say, Song came here today to prove your daughter's innocence, but you have to tell me what she did on the day of the crime?"

The old woman wiped away her tears and said: "Raise the sentence, the old body is old and has a bad memory, I only remember that the little girl went to the street to sell vegetables early that morning, but at noon, I received a message from the yamen, saying that she had killed someone, and the sentence lord, how do you say that I can accept this old bone?"

"Old mother, don't worry, according to Song's inference, although Qin Xiaoyue went to the house of the deceased Zhao Wu, she did not necessarily kill someone, and it was not necessary that she died of illness."

The old woman felt hope, and knelt on the ground again, "Lord Tiren, as long as you can prove the innocence of the little girl, the old body is willing to scatter all the family property, just for her life, the only daughter is gone, how can you let the old body live?"

Wenwu interjected on the side, "Old man, what do you think of us adults, if he accepts your money, won't he become a person like He Jin?"

The old woman realized her mistake and hurriedly apologized, Song Ci looked at the shroud next to her and said, "Old mother, your daughter hasn't married yet, I think she is also in her twenties, so you didn't find a mother-in-law?"

What to look for? Before the accident, we were too poor, and people looked down on us, and after the accident, who could take care of this matter.

Song Ci sighed and looked at the house in front of him, which had fallen into disrepair and was about to collapse. The old woman said: "Since this incident, the old woman I feel that the sky is about to fall, I wanted to go to Lin'an to sue the royal court, but unfortunately the old woman is old, I am afraid that if I can't go to Lin'an, I will lose my life, and I won't even see the last side of the little girl at that time."

Song Ci understands, who can hope that a white-haired person will send black-haired people in?

Wenwu said: "Old man, rest assured, our lord is a prison officer personally appointed by the emperor, and with him, your daughter's grievances can also be clarified."

The old woman raised her head and looked at Song Ci in disbelief, "Lord Criminal, are you really appointed by the emperor?" God, God is gracious, the criminal officer must be the contemporary Bao Qingtian!"

Song Ci said: "The old mother has won the award, I'm ashamed, Song Mou took the position of criminal officer, and he hasn't solved a single case yet, so this contemporary Lord Bao can't help it."

Wen Chengdao: "Didn't the adults just be hand-picked? Why don't we start with this Zhendong County?"

Song Ci nodded, the four of them chatted a lot, and finally returned to walk on the road.

"Wencheng Wenwu, you soldiers are divided into two ways, immediately go to all the pharmacies in the county to ask, who has bought a large amount of arsenic recently, especially Qin Xiaoyue and Zhao Wu, he grows vegetables, I believe many people have seen it."

The two received the order and acted immediately, Song Ci walked along the street, saw an old farmer pick up a bowl of white water next to him and drank it, pounced, and spit it all out the next moment.

Song Ci walked over and asked, "Old man, is this white water not delicious, or is it ......?"

The old man said: "Old man, I'm old, I don't have a good memory, this water is just salted, I am going to wash the vegetables with salt water, so as to kill the insects on it, but I forgot, as soon as this salt water enters my mouth, I feel it, and I almost didn't drink it in one gulp."

Song Ci dreamed of enlightenment in his mind, and he had a bold speculation, but he didn't dare to guarantee it 100%.

"Old man, I don't know how many years you've been selling vegetables? I don't know how the income is?"

The old man said: "Hey, old man, I have been working for more than 20 years, and now I can't do it anymore when I am old, I plan to wait a few days and stop asking and let the children be responsible."

Song Ci stared at the brine on top of the vegetables, "This brine can really kill insects?" Wouldn't it be salty if someone bought it and cooked it at home?"

"Salty? Hehe, it's better to be salty than to use arsenic, now many vegetable farmers use arsenic to kill insects, anyway, they don't pour vegetable leaves, but vegetables, poison does not kill people, and the yamen does not hang up at all. ”

Arsenic? Vegetables?

Song Ci already had a very clear line in his mind about this matter, and he felt that this matter should not be so complicated.

Saying goodbye to the vegetable lane, Song Ci returned to the yamen, He Jin was playing with birds in the yard, and when he saw Song Ci, he reminded, "Song Tixing, two days have passed since the fifth day, I don't know, can you figure out this matter?"

Song Ci said: "Thank you He Zhixian for reminding me, Song now knows a rough idea, and Song promises here that after three days, he will definitely come up with a piece of evidence to prove Qin Xiaoyue's innocence."

He Jin raised his eyebrows, he felt that things were not simple, vaguely, he couldn't see through Song Ci, and he also felt that this person was very not simple.

"Shushi, at night, you quietly came to find out, Song Ci's two subordinates are not there, and this official thinks that they should have found some important clues."

"It's Lord Ho!" Shushi said: "What if-this Song Ci really finds some witnesses, what will happen then?"

He Jin said: "It's not simple, you just get the person, see how he solves the case."

Shushi ran out and ran errands.

At nightfall, Wen Cheng and the others entered the house, "My lord, we have already checked, there are more than ten pharmacies in the county, and dozens of copies of arsenic have been sold, and the buyer can't check the goods." ”

Song Ci said: "Mainly Zhao Wu and Qin Xiaoyue, have you asked, have they bought it?"

"It's... My lord, only Zhao Wu has bought it, but in addition to him, there are many other people who have bought it, mainly for vegetables. ”

Song Ci already knew that this matter would soon come to light, "Wen Cheng, have you asked what the price of these arsenic is?" Can ordinary people afford to spend?"
