Gulou Hutong is located in the northwest of the outer city. The location is relatively remote. In addition, the terrain is high and uneven. Therefore, there are not many residents, mainly local settlements. Last year, a part of Hebei victims with small family properties moved into Hebei.

In such places, the law and order will naturally not be very good, and everyone is used to sweeping the snow at the door, and rarely pays attention to irrelevant others.

Therefore, last spring, there was a tragedy in which an old man who lived alone drowned in his own water tank and was not discovered until midsummer.

And the reason why this case was reported early in the morning was because someone wrote the six **** words of ‘self-inflicted iniquity’ on the door of the murder scene.

"My lord, because I didn't know in advance that you were going to deal with the case personally, after checking the scene, I ordered someone to carry the body... my lord?"

While leading the way, Master Qi gave a detailed introduction to the situation, but when he waited in the courtyard, he looked back, but Sun Shaozong was nowhere to be seen.

He turned back in a hurry, and saw Sun Shaozong outside, staring at the blood on the door panel.

"grown ups."

Master Qi hurriedly explained: "I have carefully observed that these blood characters were written with non-dominant hands. It is necessary to find out the real culprit with the handwriting. I am afraid that it is not easy to determine the only thing that can be determined right now. The murderer has a certain degree of calligraphy skills."

These words coincided with Sun Shaozong's previous speculation.

Sun Shaozong nodded, but he still looked carefully, and then followed Master Qi into the yard.

As soon as I entered the gate, I saw three corpses lying beneath the tattered western wall, one of which was covered with white cloth, and the other two were unobstructed.

The reason for this difference is naturally that the three identities are officials’ children, even if Ma Yingjue is dead, his treatment is different from the two young servants.

However, at first glance, there seems to be little similarity between the two little servants and the portraits painted by Ma Chunfeng during his lifetime.

This is mainly because the two corpses were both poisoned and died. Their complexions were dark and blue, their facial features were distorted, and a considerable degree of swelling. It may be an exaggeration to say that they were completely unrecognizable, but ordinary people want to distinguish their original appearance. It is extremely difficult.

Only by being proficient in on-site exploration and knowing how to restore the basic appearance of the deceased’s old criminal names with the facial contour and the local spacing ratio of the facial features can we see the connection between the two.

From this it can be seen that the professional level of Master Qi is still quite good.

"grown ups."

Master Qi led the crowd to the corpse, first lifted the white cloth, pointed to the wide-eyed, open-mouthed young deceased on the stretcher, and introduced: "This is Master Ma. When examining his corpse, , Found that the boots were marked with the words "Changlong Old Brand" and the date of shipment. Only then did he trace his identity."

As he said, he bent over and carefully peeled off Ma Yingjue's neckline, pointed to the blue-purple fingerprint on it, and said: "According to the investigation, Ma Gongzi should have died of suffocation caused by choking his throat."

"Because when we arrived, his body was still tied to an imperial chair, and a soft cloth was stuffed in his throat, so there was no trace of struggle."

"Based on the characteristics of the body's surface, it is speculated that the time of his death should be between yesterday afternoon and evening."

Having said this, Master Qi turned his head and pointed at the two young men who were poisoned to death: "The fingerprints of these two people have also been compared in the next. They do not match the marks on the Ma Gongzi's neck, and can basically be ruled out. After the two of them killed someone, there was a possibility that they would be poisoned to death."

When investigating cases these years, fingerprints were not neglected, but the means of extracting fingerprints were limited. Unless it is the case where the fingerprints are clearly printed on the neck of the corpse, it is difficult to make a careful comparison.

Master Qi obviously wanted to show off his skills in front of Sun Shaozong. After analyzing the fingerprints, he began to analyze the cause of death of the two young men.

"There are three cups on the square table inside. Two of the cups seem to have some tiny white powder stuck to the bottom, but there is no similar residue in the jug. Therefore, it is inferred that the poison should have been applied to the cup in advance. of."

Having said that, Master Qi gave in and said, "Sir, do you want to go in and take a look?"

"No need for now."

Surprisingly, Sun Shaozong shook his head and said confidently: "If my inference just now is not wrong, it shouldn't be difficult to find the murderer."

"Not difficult?!"

Master Qi was taken aback. The murderer seemed to leave his fingerprints carelessly, but he did not reveal much information.

Therefore, Master Qi analyzed all the details of the scene, and could not find many clues about the murderer, and Sun Shaozong just arrived at the scene, how could it be...

Could it be that he deliberately talked big in front of him?

Thinking of this possibility, Master Qi couldn't help but question: "But I don't know where the adults are going to start and catch the real culprit?"

"This is Qiu Yunfei, Zhao Wuwei!"

"The next official [villain] is here."

"You immediately go to the government office to gather people and search all shops selling pen, ink, paper and inkstone, centered on Gulou Hutong, and ask if they have regular customers yesterday. They used the cheapest inferior pen, ink and paper, but suddenly they bought high-end goods!"

Qiu Yunfei and Zhao Wuwei agreed and took their orders.

Shiye Qi frowned beside him, hesitated and couldn't help but questioned: "My lord, do you think the murderer bought a new brush to write those words?"

Seeing that although he was in control, he still couldn't help showing the expression of "Are you kidding me?"

Sun Shaozong took the note from his sleeve and handed it to Master Qi: "This is the blackmail letter sent to the Ma family by the murderer on the 25th night."

After Master Qi took a few glances, he explained: "It is obvious from this note that there are signs of bifurcation on the tip of the pen, which shows that an old brush is used."

"Furthermore, based on paper and ink analysis, the quality of this brush will not be as strong as that."

"The door panel is rotten and mottled, and the surface is extremely rough. The writing difficulty should be more difficult than that of inferior rough paper. But this official has only carefully observed it. The messy traces are obviously less than the former, and there is almost no hair removal."

"This is obviously a new pen, and it's a new pen of excellent quality!"

"Considering the murderer's calligraphy skills and the long-term use of the four treasures of the study of inferior quality, it is reasonable to have a strong and urgent desire for these things."

Master Qi held the note and listened to Sun Shaozong's analysis of this wave, he couldn't help but sigh that his observation was meticulous, but...

"My lord, even if this is the case, you can't conclude that he bought the Four Treasures of the Study in a familiar store, right?" Master Qi questioned: "If he randomly chooses an irrelevant store, wouldn't we be in vain? "

Sun Shaozong smiled and said, "The reason why I judged this way is still from those six blood words."

As he said, he turned around and pointed at the door, and asked: "When you saw the six blood characters, what was your first impression?"

"Arrogant!"

Master Qi blurted out: "The murderer is clearly provoking the government!"

"That's right~lightnovelpub.net~ Sun Shaozong nodded and said: "If you don't have these six characters, you might have to wait until the corpse is highly decomposed before being discovered by your neighbors. By then, there will be much less useful information. "

"But the murderer chose, and took the risk to write six blood words on the door, so that the government can immediately know that three people died here, three people who deserved the crime!"

"This is both arrogant and ostentatious!"

"Such an arrogant person who likes to show off has been depressed for a long time; he has a proud hand of calligraphy, but he can only afford the cheapest pen, ink, paper and inkstone!"

"Perhaps sometimes he is still shy in his pocket and can't afford to buy stationery. Even if the store hasn't ridiculed him for this, he might still accumulate a lot of resentment in his heart."

"When he suddenly got a big unexpected windfall and couldn't wait to retaliate against his previous life, do you think he would choose Jinyi Night Walk and go to an unfamiliar shop on purpose?"

"So my inference should be about 70% certain!"
