No trace of espionage

"Mr. Lin, what happened to Mr. Tian?" Professor Du asked without answering.

"This..." Lin Chuang pondered, wondering whether he should tell him the truth.

"Oh, I see, I shouldn't have asked, I shouldn't have asked. In fact, everyone who lives here almost knows that something happened to him. A large group of people came and went in and out of his courtyard in the morning. The chief of your bureau I personally came forward, it seems that Teacher Tian..., oh." Professor Du sighed.

Hearing his tone, I was very sorry.

"To be honest, something happened to Mr. Tian." Speaking of this, there is no need to hide it.

"I hope Director Lin can solve the case as soon as possible. Mr. Tian is really a good person, a rare young talent."

"Lin must try his best."

"I didn't hear any movement over there last night. It was only this morning that I heard footsteps over there, looking very anxious."

"About what time?"

"Six or seven, I'm not sure."

"Who else is in your family?"

"Except for our old couple, it's Sisters of Lotus."

Professor Du pointed to the maid and said.

"Do you have any children?"

"Yes, one son and one daughter are very competitive. The son went to the United States to study abroad and is also a medical student. The daughter is married and went to Hong Kong before the Songhu Battle. Her husband is teaching at the University of Hong Kong."

"Oh." Lin Chuang nodded, feeling a little disappointed.

"Professor Du, do you have a ladder at home? The kind of narrow ladder that can go up to the roof?" Lin Chuang asked again.

"Have."

"Can you take a look?"

"Of course, Director Lin, please come with the little old man."

As Professor Du said, he stood up and walked to the East Wing. Aunt Lian opened the door and saw a wooden ladder

From a distance, it looks exactly the same as Tian Chuncai's ladder, except that Du's ladder is more elegant, with a layer of tung oil on it, making it look very shiny.

Lin Chuang approached and took a closer look, and couldn't help but be overjoyed, because he found that there were marks on the ladder!
There are footprints and handprints!And it's messy.

He turned around and looked at Li Shiqun, without saying a word, he just pointed to the footprints and handprints on the ladder with his finger.

Li Shiqun took a closer look, and his eyes were also bright.

"Professor Du, when did you use this ladder?" Lin Chuang asked.

"Used it, the day before yesterday."

"You? Can you climb a ladder?" Lin Chuang asked suspiciously.

"No, no, the little old man is old, how can he get on the ladder? Last year, there was a place on the roof where rain seeped in. Isn't it the rainy season soon? The little old man wanted to repair it in advance to prevent rain from seeping again, so, just Ask the people from the school's logistics office to repair the roof."

Lin Chuang said: "Professor Du, I will take this ladder to the next courtyard first, and I will return it after the case is over, is that okay?"

"Of course." Old man Du readily agreed.

Mao Yiming didn't wait for Lin Chuang to scold him this time, and immediately had someone carefully lift the ladder out.

Lin Chuang glanced again, but found nothing like a long-handled murder weapon.

"Excuse me, farewell!"

Lin Chuangchong cupped his hands to Professor Du and left.

Old man Du was very enthusiastic and kept sending Lin Chuang to the gate.

What he learned from Court No. 4 gave Lin Chuang the hope of solving the case, although in Lin Chuang's view, the possibility of old man Du committing the crime was unlikely.An old man who is very honest on the surface but actually very "motivated" in his heart will kill people?
But it cannot be ruled out that he is an underground party, and it cannot be ruled out that he participated in the murder.

Even so, Lin Chuang never asked about the ladder.

He believed that Mao Yiming would definitely find out who the maintenance worker was and whether the footprints and handprints on the ladder matched.If none of these can be done, then Lin Chuang will definitely scold him.

……

Then, Lin Chuang investigated the other three houses in the order of 5, 6, and 2. The results were basically similar to the situation of old man Du’s house. It seems that there is no possibility of committing a crime.

Of course, the ladders were also checked, they were all covered in dust and had never been used.

There is the last one left, which is the No. 1 courtyard in the west.

At the door, Li Shiqun introduced as usual: "The home of Wu Zhizhong, professor and director of surgery, Wu Miaoyun is his daughter."

"Ah?" Lin Chuang didn't care about getting angry anymore, and looked at Li Shiqun in surprise.

Li Shiqun nodded, spread his hands, and said nothing.

After Lin Chuanglue thought about it, he understood why Li Shiqun didn't tell him earlier, why he didn't take this place as a key investigation.

No one informed Lin Chuang in advance, because Li Shiqun didn't want him to know these things, and meant to keep them secret.

The reason for not focusing on this place for investigation is because of Hu Fengzhi's presence.

"Then, should we still check?" Lin Chuang asked.

"Investigate, of course we must investigate, even if it is for someone's sake, we must investigate." Li Shiqun replied.

Lin Chuang nodded.

The person Li Shiqun mentioned was Hu Fengzhi.

In other words, it's good to pretend.

Otherwise, all the other families have checked, but this one has not. What does that mean?
"Is there any problem with Wu Zhizhong?" Lin Chuang asked.

"I checked it out a long time ago. He is an introverted, honest and pedantic person. Except for teaching and seeing a doctor, he never participates in other activities, and even rarely participates in gatherings of colleagues and banquets for students and parents. He is very particular about etiquette. I always feel that the current social atmosphere is not good, and I especially respect and miss the feudal system." Li Shiqun introduced.

Hearing this, Lin Chuang didn't rush to knock on the door, but walked a few steps to the west and left the gate of Wu's house.

Li Shiqun followed.

"The old and the young?" Lin Chuang asked.

"Yes, you are very wise. In fact, he is a rich Manchu family. His surname is Fucha. He fled to Japan on the eve of the [-] Revolution. He said he was studying, but he was actually avoiding disaster. After returning to China, he changed his surname to Wu."

Lin Chuang is full of vigilance for those returning from studying in Japan.

I feel that these people, few of them are patriots, and many of them act as "leading parties".

"Where is his wife? Is it Chinese or Japanese?"

"Chinese. After returning to China, she married a local from Shanghai. She fell ill and died shortly after giving birth to Wu Miaoyun."

"No more strings?"

"Honest man, it's too rigid. He has a deep relationship with his wife, and he doesn't want to marry again. Many people have persuaded him, and he has been relaxed, but he has to wait until Wu Miaoyun gets married before considering the remarriage."

"So, father and daughter depended on each other for life, pampered Wu Miaoyun very much, and developed Wu Miaoyun's rebellious character?"

"It's right and wrong. Wu Zhizhong loves his daughter very much, but he is not used to her. In terms of personality alone, Wu Miaoyun is bold and generous, not at all graceful and restrained like our Han girls. Therefore, I think Wu Miaoyun's personality is not It was acquired, but brought from her bones."

Lin Chuang said: "Perhaps it is her character that Hu Fengzhi is fascinated by?"

"do not know."

"Since Wu Zhizhong is so rigid, how can Hu Fengzhi enter the Wu family's door? Why don't you call him out?"

"That's right, Wu Zhizhong thinks that free love between men and women is ruining the style of the family. So, it's not that Hu Fengzhi has never been here in the past, but he couldn't enter the door every time. However, since Wu Miaoyun came back, Wu Zhizhong has changed..."
