Gu Yunfei came back and asked, "Tell me quickly, what are you doing when you go to Mingshu Villa to find his female servant, Aunt Lin?" Why don't you talk to Ming Shu first? ”

Luo Fei said assertively: "You follow my steps, don't ask too much." ”

Gu Yunfei couldn't ask the answer she wanted from his mouth, and said knowingly: "How come I, the official policeman, am not as smart as you, who is not a detective?" I still have to be led by the nose by you. ”

Luo Fei said: "I said, I will help you solve the case, and then you will wait to accept the reward and promotion, as well as the reputation you want." ”

Luo Fei's car stopped outside the wall of Mingshu's villa, jumped out of the car and learned a few cuckoo calls, and after waiting for a while, Mingshu's maiden, Aunt Lin, opened the door, poked her head out, and beckoned them in.

Gu Yunfei pulled Luo Fei aside and asked, "Oh my God, you and that female servant still have a code." Confess, what's the situation? ”

Luo Fei said: "You see, Aunt Lin heard the cuckoo call, so she opened the door for me." ”

Gu Yunfei said: "It seems that you are usually very close. ”

Luo Fei said: "Of course, after all, she is the closest to the biggest suspect Ming Shu." ”

Gu Yunfei said: "I think it's a female employee who thinks you don't look ugly, I like you, right?" ”

Luo Fei said: "No. You'll find out what she likes about me later. Because I have something she likes, I give it to her, and she does what I command. ”

Aunt Lin, the female servant, waited for them to enter the door, and pulled Luo Fei aside, for fear that Gu Yunfei would hear something.

The female servant, Aunt Lin, handed a handbag to Luo Fei and instructed: "You must return it as soon as possible, otherwise, the man asked where the dress went, and I couldn't explain."

Luo Fei gave her an affirmative look and then shoved a few dollars into her hand.

Gu Yunfei pursed her lips and looked at them with disdain.

After the transaction was completed, Luo Fei proudly handed Gu Yunfei a look, signaling that they could go.

On the way back, Gu Yunfei kept chattering and asking Luo Fei questions.

Gu Yunfei asked, "Tell me the truth, what kind of transaction did you make with Aunt Lin?" ”

Luo Fei said: "The clothes of Ming Shu that I bought from Aunt Lin for US dollars, the clothes that Guan Na wore on the day she died." ”

Gu Yunfei was curious: "What do you want his clothes for?" ”

Luo Fei said: "We live in modern times, so we have to learn to solve cases with the help of modern scientific instruments and knowledge, and we know the trace physical evidence, right?" ”

Gu Yunfei said: "Of course, I know that the history of the application of trace physical evidence to solving the case is not too long, with the help of physics, chemistry and instrumental analysis and other methods, through qualitative and quantitative analysis of the composition and structure of the relevant substances, the types of samples, the composition of the samples and the suspected samples are detected and analyzed, and then the results are used to solve the case, and the United States is the first to use trace physical evidence to detect homicide." ”

Luo Fei said: "The knowledge of books is very familiar to memorization, but it will not be applied to the reality of life." ”

Gu Yunfei said: "What do you want?" ”

Luo Fei said: "Ming Shu's dress is analyzed by high-end instruments, such as a microscope, and it may be seen that a certain part of the clothes is stained with ink. ”

Gu Yunfei said: "Isn't it seen with the naked eye after being stained with ink?" ”

"Can I see the ink-stained parts that have been washed?" Luo Fei said, "Yesterday I had a phone call with Aunt Lin and asked Ming Shu what clothes she wore on a business trip to the UK that day, and she mentioned that Ming Shu never washed his own clothes, but he washed the clothes he wore to the UK himself." It made me suspect that there must be something on it that needed to be washed off myself so that no one else would find out. He is a rich man, and there are people in the house, is it necessary to wash his own clothes? So I made an appointment with Aunt Lin to pick up the clothes today, and I want to see what Ming Shu washed off. ”

Gu Yunfei picked up the paper bag and opened it to look at it, it was a high-end cotton black jacket, she especially looked at the sleeves and collar, and found that the cuffs had been heavily scrubbed.

Gu Yunfei said: "Could it be that there is ink on the cuffs?" Some of the whiskers from the scrubbing of this place are whitish. The clothes have been scrubbed, what else can we detect! ”

Luo Fei said: "When the time comes, focus on the cuffs." Even if it has been washed, there will definitely be ink residue in the fabric. ”

Gu Yunfei said: "Who are you going to ask for help with your testing?" We have to find a good microscopy expert to be able to help us. ”

Luo Fei said: "When I was studying in the UK, I knew a doctor who was a world-famous microscopist who helped the police in many countries to find trace substances on the suspect items with the help of microscopes, and helped them solve impossible cases. I'm going to send him the clothes in the hope that he can help us. ”

At this time, Gu Yunfei received a strange phone call, it was a woman with a small and gentle voice, asking her if she was Officer Gu Yunfei.

Gu Yunfei repeatedly said that it was her, and the strange woman asked her to meet at 6 o'clock tonight in the pavilion in the middle of the fish pond in Zhongshan Park, and she could only go to the appointment alone, and she wanted to tell her the story of Yang Biao.

Gu Yunfei glanced at Luo Fei, and Luo Fei gave her a positive look.

Gu Yunfei readily agreed to the strange woman's request.

Luo Fei looked at his watch and said, "It's only 2 o'clock, you go back to the police station and show me Kuanna's relic mobile phone." ”

"Kuanna's father took it away, and he insisted on asking for her mobile phone to keep it as a memory, and I, as a distant relative of Kuang's father, gave it to him as an exception."

"Do you have her father's contact information?"

"I have his father's cell phone number."

"Call him now and ask him if he has touched his phone."

Gu Yunfei called Kuang's father, he hadn't returned to his hometown yet, and now he was living in the Sifang Hotel on the outskirts with Kuang Na's ashes, waiting for the police to solve the case and find the murderer, so that he could return to his hometown with peace of mind. As for Kuanna's relics, he didn't touch them.
