The next morning, Zhou Erya slowly and methodically used Guanghe bean curd, olive vegetables, and meat to loosen the white porridge with conpoy, and after eating, he looked at the recent newspaper, and was not in a hurry to go out at all, but Han Yu was anxious like an ant on a hot pot, pacing all over the house.

"I said, young master, didn't you say that you were going to see some principal today? What time is it, and you still haven't left? Han Yu kept looking at the time, and had no intention of doing anything else.

Zhou Erya drank black tea, flipped through the newspaper, and said unhurriedly: "It's only eight o'clock, do you think it's school so early?" What's more, the principal I'm going to visit retired last year. ”

Han Yu was stunned, he was dizzy by Gu Xueli's hair yesterday, and he didn't figure out what the principal was, thinking that he was the current principal.

If it's an ordinary reception, eight o'clock is indeed a bit early.

After a while, Han Yu couldn't help it: "Half past eight, can you go?" ”

He doesn't understand the schedule of those upper-class people, anyway, he sees that Zhou Erya is leisurely reading books and newspapers in the morning, and probably those people are like this.

"Don't worry, Murong hasn't arrived yet." Zhou Erya believes that on today's occasion, Murong will definitely not be absent.

Sure enough, as soon as his words fell, Adjutant Cai walked in happily: "Young Master, Miss Murong is here." ”

Zhou Erya put down the teacup, stood up, and nodded to Han Yu: "You can go." ”

As he spoke, he put on his coat and waited for Murong to come in, and without saying anything nonsense, he asked Adjutant Cai to drive to a mansion on Julaida Road.

Xiafei Road is not far from Julaida Road, which also belongs to the French Concession, but the environment here is more secluded than Xiafei Road, and the cultural circles have heads and faces, often buying property here, attracting many wealthy businessmen and even underworld figures to follow the trend here and raise land prices.

However, what Zhou Erya visited today is really a master in the field of culture and education.

Qian Yuanyi was a person in the former Qing Dynasty, who went abroad to study when Gengzi paid the indemnity, and has been engaged in education since he came back. Before World War I, she was the president of Shanghai Boyne University, the predecessor of the women's university.

He retired last year and lived in the Julai Daluqian Mansion, entertaining himself with calligraphy and painting, and he was also a well-known person at sea.

Ordinary people may not be able to make an appointment to see him.

As soon as Zhou Erya signed up, she was immediately welcomed in.

"It's still easy to use the name of the Overseer's son......," Han Yu sighed.

Even if he is a master of the education industry with two sleeves and a hard head, he has to give face to the Shanghai Overseers.

"It's not."

Zhou Erya shook his head, he didn't mind Han Yu's teasing, anyway, he always felt that it was convenient to come, and he would not be inferior or proud because of his identity.

"I'm reporting the name of the Eryu Detective Agency this time." Zhou Erya said with a smile.

Han Yu was stunned: "He is willing to meet someone from the detective agency?" ”

In Han Yu's impression, this kind of bigwig is not such a good-tempered character, and a detective agency came to the door rashly, and people said they would see each other?

"When I asked Adjutant Cai to make an appointment, he said that we were investigating the murder case at the Women's University, and the other party agreed to meet."

Zhou Erya's tone was calm.

"That's it?"

Han Yu felt that something was wrong.

Although Qian Yuanyi served as the president of Boyne University, he had an old-fashioned personality, and after Boyne was changed to a women's university, he resigned as president and went to work in the Ministry of Education in Beiping.

Speaking of which...... He really had nothing to do with the murder at the women's college, and there was no need to care about it.

So...... may have heard that the Eryu Detective Agency was opened by the Overseer's son, so he gave enough face.

After all, from the opening of the Eryu Detective Agency to the cracking of several strange cases, its reputation is just outside, and the people at the top are thinking of ways to stuff some money when they have nothing to do.

With doubts, Han Yu and Murong who had not spoken much and only quietly followed them into the study room of the Qian Mansion.

Qian Yuanyi was sitting on the Taishi chair, with a blank piece of paper in front of him, holding a brush in his right hand, not knowing whether to write or paint, but he never put pen to paper for a long time.

At first glance, Murong found a few ink stains on the white paper, which seemed to be a long-term book.

- Principal Qian's mood doesn't seem to be very good.

"Hello principal, I'm a junior at Women's University, Murong." Murong remembered the principal.

When she first entered the school, she also invited him to read the school motto and school rules for everyone, I don't know if the principal still remembers her.

"Murong classmate, why are you with them?" Principal Qian obviously remembered this excellent student - after all, her family situation was one of the best among the students, not to mention that he also had a friendship with the Mu family.

"Principal Qian, she is the client." Zhou Erya stepped forward to say hello, and said straight to the point, "It's been in the newspaper these days, you should have seen the news of Miss Bai Fei's death, I don't know how to feel in your heart?" ”

This way of asking questions was not polite at all, Han Yu's eyes widened, and he didn't know how Qian Yuanyi would react.

Principal Qian just smiled bitterly, but was not angry, he threw the pen casually, and looked at Zhou Erya with blazing eyes.

"I've wondered countless times what kind of person it would be to torture me with this question."

His tone was heavy, trembling with a little excitement.

"But I never thought it would be such a young detective."

After so many years of inner torment, there is finally a channel for catharsis. Principal Qian didn't care about Zhou Erya's attitude at all, and even admired his straightforwardness.

Han Yu was even more confused, and realized more and more that it was because of his identity as the son of the Overseer that Principal Qian was so polite.

"It was I who entrusted Mr. Zhou to investigate the death of Bai Fei at the Women's University, and he found here."

Murong Tan said frankly.

Zhou Erya was quietly watching Principal Qian, and Principal Qian was also looking at him silently.

The eyes of the two silently collided in the air, but without any sparks, like sea water meeting sea water, devouring each other.

This big man in the cultural and educational circles has long been old, but his silver hair is not messy at all, and his back is straight, but there is a decadence in his expression that should not belong to him.

"The women's university is the original Boyne University. It's been more than a decade since I stepped down as president of Boyne University, why should I be approached for this case? ”

Principal Qian responded carefully, with a contemplative demeanor, as if he was arguing, but as if he was talking to himself.

"Of course you know why." Zhou Erya looked into his eyes and said word by word, "Because the murderer who killed this young girl is you!" ”

What the?!

Han Yu, who was on the side, was taken aback, and couldn't believe his ears.

What is Zhou Erya talking about?

Anyway, this old man has nothing to do with this case, right?

Not to mention that there was no time to commit the crime at all, and the two had nothing to do with each other, the old man didn't even know this girl, so how could he have the motive for killing?

In the face of such accusations, what can this respected senior do if he suddenly becomes angry? Han Yu was anxious and embarrassed for Zhou Erya.

Compared to Han Yu's nervousness, Murong silently retreated outside the door, not knowing if he couldn't bear to watch the teacher face such accusations, or if he didn't want to see the teacher embarrassed in front of the students.

However, Principal Qian's expression was gloomy, and he didn't get angry as Han Yu imagined, but just whispered in a low voice:

"No...... It's not me ......."

There was deep pain and guilt in his tone.

"I know it's not Bai Fei that you want to kill."

Zhou Erya's tone was calm, but she was pressing step by step.

"What you want to kill is only twenty-year-old Qi Zhongmin."

Hearing this name, Principal Qian finally couldn't sit still, and stood up on the ground, and the Taishi chair slid backwards for a long time, making an unpleasant creaking sound on the terrazzo floor.

"You...... You got it? His voice trembled, almost unsteady, and it seemed that the name Qi Zhongmin had made him unable to calm down to this day.

Zhou Erya nodded and said lightly: "Although I don't know the details, I probably guessed it, I just wanted to invite Principal Qian to you today, and finally confirm it." ”

Principal Qian waved his hand decadently, his lips were open, but he couldn't say a word for a while.

"What the hell is going on?"

Han Yu was so shocked that he could only ask Zhou Erya in a low voice.

Zhou Erya looked at Principal Qian and saw that he didn't speak, so he sighed and spoke: "Since Principal Qian can't say it in person, let me take a look at this murder case that has been separated by twenty years." ”

The motive and killing intent both originated twenty years ago.

The final completion was twenty years later.

"Twenty years ago, Boyne University was not established for a long time, but because of President Qian's efforts, it has become a well-known university in China, which can be compared with Fudan and Jiaotong University, even if it is not much better than Beijing Normal University and Tsinghua University in the north."

This is the pride of Principal Qian's life, hearing Zhou Erya mention this glory, and even showing a look of relief on his face, the previous depression gradually disappeared and was replaced by emotion.

At the end of the Qing Dynasty and the beginning of the Republic of China, universities were established in various places, and the most famous universities in the north were Beijing Normal University Hall and Tsinghua University, and in Shanghai, Boyne University, which President Qian co-founded, was also extremely successful.

"However, the good times don't last long, and in the troubled times, it is not so easy to quietly do learning and education."

With Zhou Erya's narration, Principal Qian's body shrank and sat back in his chair, his eyes flickering again, and he was even more emotional.

At the beginning of the century, when the Republic of China was first established, the country was in ruins, and various trends of thought were constantly spreading and preaching. The university student group is exposed to the latest ideas, and they are also a group of people who stand at the forefront of the trend.

At that time, the country was weak, and after the establishment of the Republic of China, it failed to improve, the Beiyang warlords confronted the southern revolutionaries, the local overseers fought for independence, and foreign forces took the opportunity to invade and plunder, and the people were still living in dire straits.

At this time, many young people joined the student movement, fighting and protesting for the salvation of the country.

Principal Qian didn't like this.

Again and again, he announced a ban at school assemblies, asking students at Boyne to refrain from political involvement and concentrate on their studies, with more severe tone and stricter measures.

He even expelled two activists - also his beloved students, but the country is suffering so much, how can the youth sit idly by? No matter how strict the discipline is, it cannot stop the enthusiasm and courage of young people.

Qi Zhongmin is a student who has a special headache for Principal Qian.

He was witty, courageous, passionate, and knew how to fight.

Principal Qian talked to him several times, but Qi Zhongmin was always able to cover up the past in clever ways, and he couldn't afford a head-on conflict, and the principal couldn't do anything about him.

He then used the school radio station to give a speech to his classmates. Principal Qian stopped him several times, but he couldn't find a suitable school rule to stop it.

At that time, the situation was tense, and the students also secretly planned and organized, wanting to lead the students of Shanghai to hold a big parade - this news was learned by Principal Qian in advance, he panicked, knowing that the source must be Qi Zhongmin, so he went to dissuade him in person, and persuaded him for a long time, but Qi Zhongmin was unmoved.

"From that moment on, you were killed."

Zhou Erya connected the school history materials with Qi Zhongmin's file, finished speaking in one breath, and looked at Principal Qian.

Principal Qian's expression was very exciting, reliving this piece of history that he wanted to bury, his hands were already clenched.

"You want to kill this student, so that you can be a hundred, so that other students can study in peace."

The idea may be ridiculous, but judging by the pained expression on Principal Qian's face, it is very likely to be true.

Han Yu was already dumbfounded.

Someone as upright as him could not understand such a motive?

Han Yu guessed wildly that the gunman who killed Qi Zhongmin was found by the principal? But I don't think it makes sense, it's weird!

Zhou Erya's subsequent analysis and deduction solved Han Yu's doubts.

"But you don't have the idea of killing people directly, and as an educator, as a cultural person, you certainly can't do such a thing. You think deeply, hoping that Qi Zhongmin will die in an accident. ”

"Every night, he goes back to the radio station to broadcast......"

So that's it!

Han Yu exclaimed in surprise, and suddenly realized: "Principal Qian deliberately rebuilt the stairs at the entrance of the radio station, making it crooked, and it is very easy to fall in the dark—and there is a sharp fence on the opposite side, which is a killing machine!" ”

He was creepy, and he never thought in this direction.

INTERVIEWER What kind of school can do such a thing?

Principal Qian buried his head in his chest and put his hands in his gray hair, so ashamed that he couldn't say a word.

"You're right."

Zhou Erya nodded to Han Yu and approved: "This is a murder trap, maybe once or twice, Qi Zhongmin can escape, but as long as there is an accident, as long as there is a small negligence in the night, it can kill him." ”

Whoever walks down that staircase will feel particularly awkward, if a little water is sprinkled on a slippery day or other factors, it is easy to fall, and that inclination, coupled with the ungripping escalator guardrail, will not stop at all, and will almost, surely fall straight downstairs.

Downstairs, it's a sharp fence like a monster's teeth!

Qi Zhongmin was supposed to die in an accident.

It's just that I don't know whether to say it's lucky or unlucky, before he had an accident, he encountered a love killing.

For Principal Qian, it must have been a sigh of relief, at least ...... He escaped the condemnation of his conscience.

"So, it's not a staircase, it's a murder weapon?"

Han Yu vaguely guessed yesterday - when Zhou Erya investigated the death twenty years ago and asked him to measure the stairs, he didn't think about it in this direction, but he didn't think it was ridiculous, he didn't expect Zhou Erya to really question Principal Qian with this.

And Principal Qian's attitude is even more chilling.

He sat quietly in the chair, patiently listening to Zhou Erya's speculation, without a word of rebuttal.

Even, Principal Qian's face often showed a look of pain.
