Gulou Hutong is located in the northwest of the outer city, the location is relatively remote, coupled with the terrain is high and uneven, so there are not many residents, basically to the local dilapidated settlement, last year and moved in a part of the small property of Hebei disaster victims.

In such a place, the law and order are naturally not very good, and everyone is used to sweeping the snow in front of their doors, and rarely pays attention to irrelevant bystanders.

Therefore, last spring, there was a tragedy in which an elderly man who lived alone drowned in his water tank and was not found until the middle of summer.

And the reason why this case was reported early in the morning was because someone wrote on the door of the murder scene the six bloody words 'self-inflicted evil cannot live'.

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

While leading the way in front, Master Qi introduced the situation in some detail, but when he arrived in the courtyard and looked back, he saw Sun Shaozong's figure.

He hurriedly turned back again, and saw Sun Shaozong outside, staring at the blood words on the door panel with burning eyes.

"Your Excellency."

Master Qi hurriedly explained: "I have carefully observed that these blood characters are written down with non-dominant hands, and it is not easy to find out the real murderer by handwriting - the only thing that can be determined at the moment is that the murderer has a certain book background." ”

These words coincided with Sun Shaozong's previous speculation.

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

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

The reason for this difference is naturally the identity of the three - as the son of an official eunuch, even if Ma Yingjue is dead, the treatment is different from that of the two little guys.

However, at first glance, the portraits drawn by the two little servants and Ma Chunfeng before his death do not seem to have much similarity.

This is mainly because the two corpses were poisoned and died, their faces were black and blue, their facial features were hideous and distorted, and there was a considerable degree of edema, it may be an exaggeration to say that they were unrecognizable, but it was extremely difficult for ordinary people to distinguish their original appearance.

Only by being proficient in on-site exploration and knowing how to use the facial contours and the proportion of local spacing of facial features to restore the basic appearance of the deceased can we see the relationship between the two.

It can be seen from this that Master Qi's professional level is still quite good.

"Your Excellency."

Master Qi led everyone to the corpse, first lifted the white cloth, pointed to the young deceased on the stretcher, whose eyes were wide and his mouth was about to breathe, and introduced: "This is Ma Gongzi - when I checked his corpse, I found that the boots were marked with the words Changlong Lao, as well as the date of shipment, so I found out his identity." ”

As he spoke, he bent down and carefully peeled off Ma Yingjue's neckline, pointed to the blue and purple fingerprints on it, and said, "According to the inquest, Ma Gongzi should have died of suffocation caused by choking." ”

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

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

Speaking of this, Master Qi turned his head and pointed to the two little guys who were poisoned: "The fingerprints of these two people have also been compared below, and they do not match the marks on Ma Gongzi's neck, which can basically rule out the possibility that the two of them were poisoned again after killing someone." ”

In the early years of investigation, it was not that fingerprints were not taken lightly, but the means of extracting fingerprints were limited, and it was difficult to make a careful comparison unless the fingerprints were clearly printed on the neck of the corpse as it is now.

Master Qi obviously had a heart and wanted to show his skills in front of Sun Shaozong, and as soon as he finished analyzing the fingerprints, he began to analyze the cause of death of the two little guys.

"There were three glasses on the square table inside, and the bottom of two of the quilts seemed to have some tiny white powder sticking to them, but there was no similar residue in the flask, so it is inferred that the poison should have been smeared on the glasses beforehand."

Speaking of this, Master Qi stepped in and said, "Do you want to go in and take a look?" ”

"For now, it must be."

Who knew that Sun Shaozong shook his head and said firmly: "If my inference is not wrong, it should not be difficult to find out the murderer." ”

"Isn't it difficult?!"

Master Qi was taken aback, the murderer seemed to have carelessly left fingerprints, but in fact he did not leak too much information.

Therefore, Master Qi analyzed all the details of the scene, and failed to come up with many clues about the murderer, and this Sun Shaozong had just arrived at the scene, how could it be ......

Didn't he deliberately say big things 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 arrest the real culprit?" ”

"Is this - Qiu Yunfei, Zhao Wuxing!"

"Xiaguan [villain] is here."

"You immediately go to the government office to gather people, take the Gulou Hutong as the center, search all the shops that sell pen, ink, paper and inkstone, and ask them if they have any regular customers yesterday, who have been using the cheapest inferior pen, ink and paper, but suddenly bought high-end goods!"

Qiu Yunfei and Zhao Wuxing agreed and took the order.

Master Qi was beside him, but he frowned, hesitated, and couldn't help but question: "My lord, do you think that the murderer bought a new brush separately in order to write those words?" ”

Seeing that although he was in control, he still couldn't help showing an expression of 'are you kidding me'.

Sun Shaozong took out the note from his sleeve and handed it to Master Qi: "This is the extortion letter sent to the Ma family on the twenty-fifth night of the murderer. ”

After Master Qi took a few looks, he explained: "It can be clearly seen on this note that there are signs of curly hair bifurcation on the tip of the pen, which shows that it is an old brush. ”

"Moreover, according to the analysis of paper and ink, the quality of this brush will not be strong there."

"The door panel is rotten and mottled, and the surface is extremely rough, and it should be more difficult to write than the inferior coarse paper—but this official has only carefully observed that there are significantly fewer traces of messiness than the former, and there is almost no hair loss."

"It's clearly a new pen, and it's a very good quality new pen!"

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

Master Qi pinched the note, and after listening to Sun Shaozong's analysis of this wave, he couldn't help but sigh that he was really meticulous in his observations, but he was just ......

"My lord, even if that's the case, you can't be sure that he bought the Four Treasures of the Study in a familiar shop, right?" Master Qi questioned: "If he chooses an irrelevant shop at random, wouldn't it be in vain for us?" ”

Sun Shaozong said with a smile: "The reason why I judge like this is because of those six blood words. ”

As he spoke, he turned around and pointed to the gate and asked, "What was your first impression when you saw those six blood characters?" ”

"Arrogant!"

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

"That's right."

Sun Shaozong nodded and said: "If it weren't for these six words, maybe it would not be discovered by the neighbors until the body was highly decomposed, and there would naturally be a lot less useful information at that time." ”

"But the murderer chose to take the risk of writing six blood words on the door, so that the government would know that three people had died and three people deserved it!"

"This is both arrogance and show-off!"

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

"Maybe sometimes he will be too shy to pay for stationery - even if the store doesn't sneer at it, he'll probably have a lot of resentment in his heart."

"When he suddenly got a big windfall and couldn't wait to take revenge on his previous life, do you think he would choose to go night in brocade clothes and go to an unfamiliar shop?"

"So my inference should be about seventy percent sure!"
