By the time Prince Young and Watson returned to Baker Street, it was past three o'clock in the morning. As soon as he returned home, Wang Ziyang did not speak, but lay straight on the bed and rested. Seeing this, Watson didn't say anything more, but like Wang Ziyang, he fell over and rested.

When it was nine o'clock in the morning, when Inspector Lestrade knocked on the door of Baker Street, the prince bounced up from the bed with a "whoosh", quickly dressed and opened the door for Inspector Lestrade.

As soon as he opened the door, Inspector Lestrade walked in with a large pile of information.

"These are the suspects I have summarized according to your request, there are about a dozen, you can take a look.

In addition, at the bottom is the recent movements of the two deceased this time. ”

Before Inspector Lestrade could finish speaking, Wang Ziyang had already picked up the list of suspects and checked their information.

After browsing through it, Wang Ziyang narrowed it down to four, but he wasn't sure who Jack was among the four.

"Detective, let's divide into four ways, keep an eye on these four people. Don't startle the snake first, once they are ready to commit a crime, immediately pull out a gun to stop it, and catch the current one. With that, Wang Ziyang took out two copies from the four suspects and said:

"These two are the most likely ones in my opinion, and I and Watson will be in charge of one of them, you and I will be in a group, and that Anderson will be in a group with Watson, and the other two you will send a few clever people to keep an eye on it. Remember, don't have too many people, too many are easy to find. ”

As he spoke, Wang Ziyang placed the two documents on the table.

"I'll follow you after this Aaron Kominski, and Watson and the others will follow Jacob Levy.

Kominsky's home was close to where the crime was committed, and it was only natural that he himself was a tailor who was good at using knives. Most interestingly, he was also an intermittent psychopath, a member of the London Jewish community, having fled from Poland in recent years to escape the persecution of Jews in Tsarist Russia.

Kominsky had been sexually assaulted by homosexuals and had been beaten by his mother since he was a child, so he had an inexplicable hatred for women, once used a knife to kill his two sisters, and according to his neighbors, he often cursed women, which was likely to lead him to extreme revenge against society and women. ”

With that, Prince Young handed over Kominsky's information to Inspector Lestrade, and then picked up Jacob Levy's information.

"This man was a butcher by profession and had a lot of experience with knives, and likewise he was a Jew and fit many characteristics. Levi's home address and butcher's shop are near Whitechapel, and the murder site is very close. Since he is a butcher, there is no suspicion that there is some blood on his body, and he can use his position to dispose of the organs taken from the victim's body at the butcher's shop before returning home.

According to Levi's wife's information, Levi has recently suffered from severe mental problems, his business has failed, and he spends his days wandering the streets without doing his job. And from what I have observed, he seems to have a venereal disease, and it is likely that he got it from the prostitutes near Whitechapel, so he is going to take revenge on society, against these prostitutes. ”

As he spoke, Wang Ziyang handed Levi's message to Watson on the other side.

"That's what I think is the most likely person to be the murderer, and these two were also spotted near Whitechapel in the early hours of this morning. ”

As he spoke, Wang Ziyang picked up the deceased's movement trajectory under the suspect's profile.

"Okay, I'll go and set it up right away, and I'll get done in the afternoon, and I'll get back here with Anderson, and we'll split up and keep an eye on these two. Inspector Lestrade said as he stood up and was about to leave.

"What's going on?" but Wang Ziyang frowned at this moment.

"What's wrong?" Watson looked at Prince Young, and Inspector Lestrade stopped.

"According to the information, the deceased Elizabeth had gone to a fruit shop with a strange man to buy grapes on the night of her death. You know, grapes are an extremely expensive fruit, and Elizabeth's financial conditions are absolutely unaffordable, and the two main suspects want to buy a bag of grapes, and it will cost a lot of money. The question is back, why are they pretending to be nobles?"

"It's also possible that there are two murderers, one goes to kill people, and the other helps them. Inspector Lestrade said.

Wang Ziyang just waved his hand and said:

"It's okay, the murderer shouldn't be able to run between these four people, and it's not too late to think about this problem when Jack is arrested, it's possible that there are just rich people who have found these prostitutes, and Jack is not necessarily killed on the condition that he was found by a rich man. ”

"Okay, you keep thinking, I'll go first. With that, Inspector Lestrade opened the door and left.

After Inspector Lestrade left, Wang Ziyan also took the coat from the coat rack and draped it over his body, tied his scarf, and put his hat on.

"Where are you going?" asked Watson, puzzled.

"I saw a suspect in the early hours of this morning, although he is not very suspicious, but it is better to rule it out and confirm it. Wang Ziyang replied.

"I'm going with you, where am I going?"

Wang Ziyang looked back at Watson and said:

"University of London. ”

As soon as the scene turned, the duo still came to the main entrance of the University of London, and after showing the police ID card given by Lestrade, the security guard at the door also consciously cooperated with the work of the two.

"Do you have a Professor James here who is about forty or fifty years old, wearing an old-fashioned suit and wearing a ring on both his left and right hands?"

"Oh, you're looking for Professor James from the math department, he's probably still in class, so you can go to their math office and wait a minute. ”

"Okay, may I ask if he was at school last night and what time did he stay?"

"He, he came back to school at nine o'clock last night and stayed in the office until ten o'clock before leaving. ”

"Okay, thank you for your cooperation. After Wang Ziyang finished speaking, he took Watson to the office that the doorman pointed to.

The office is very large, and judging by the number of desks, there should be five teachers here, and now there is only one old man about sixty years old in the office.

When he saw the two come in, the old man thought that the students had come to visit, until the two showed their police ID cards.

"Excuse me, is Professor James based here?" Wang Ziyang asked.

"yes, what's wrong? It can't be Professor James who did something, he's fine, shouldn't be. The old man hurriedly said.

"No, no, we just wanted to come to Professor James to find out the situation, could you please show us what Professor James is working at that desk?"

As soon as he heard that James had done nothing, the old man relaxed, pointed to the table opposite him, and said:

"That's James's table, James is a very kind man, very knowledgeable, a rare mathematical genius. ”

Hearing this, Wang Ziyang walked straight to James's table and looked at it.

"The material of the white paper is good, the pen is also high-end, and the ink exudes a fragrance, and it seems that Mr. James is in good financial condition.

The desktop is very neat, and all kinds of items are also placed very neatly, so he should be a meticulous person who is suitable for learning. While thinking, Wang Ziyang casually flipped through a notebook on the table, which was full of mathematical formulas, which gave Wang Ziyang a headache.

"It's not what a police officer should do if he casually looks through other people's things. ”

At this moment, a voice came from the door, and when he heard this, Wang Ziyang put the note back and turned around. It was none other than Professor James.

"What wind brought you two to me?"

As he spoke, Professor James walked over to his desk and placed the lesson plan in his hand on the table.

"It's nothing, I just think you're funny. Wang Ziyang said to Professor James.

"No need, it's not a good thing for a detective to be interested in me, so now may I ask Mr. Detective, has my suspicion been ruled out?" James said as he sat in his seat and looked at Wang Ziyang.

"What suspicion, James, what have you done?" asked the old man across the table, a little surprised.

"According to the janitor's testimony, you have an alibi, which means you didn't do it. ”

"It's alright, Professor Stephen, I'm just passing through, and it has nothing to do with me. After James finished speaking to the old man, he turned to Wang Ziyang and said:

"Since I'm not suspicious, is there anything else you want to ask?"

"It's all right, farewell. ”

"If you go slowly, you won't send it. ”

After Wang Ziyang and Watson walked out of the office, Watson asked angrily:

"Why is he a little arrogant, do you really think we can't take him?"

"It's okay, no matter who it is, it will be unhappy to be wronged, and besides, he really has no suspicion, we really can't move him, don't forget, we're just detectives as he said, and the police ID card was given to us temporarily by Inspector Lestrade, so we don't have the right to arrest people. Let's go back and wait for Inspector Lestrade and them. ”

With that, the two left the University of London.

In the afternoon, Inspector Lestrade took Anderson to 221B Baker Street, and at the same time, he also brought two revolvers, which he gave to Prince Young and Watson for self-defense.

Wang Ziyang plans to go to Kominsky's tailor shop to make a dress and find out the details of Kominsky.

When the two of them approached Kominsky's tailor shop, they found that a postman was also with them on their way to Kominsky's tailor shop.

Inspector Lestrade immediately stopped the postman, and after showing his detective card, he said that he had come to investigate the case of Jack the Ripper, and the postman had to hand over the letter to the detective.

The detective opened the letter, and it only read:

"Old time, Whitechapel is waiting for you. "Signature - old friend.

"What does that mean?" asked Inspector Lestrade.

"I don't know, but at least it proves that Kominsky has something to do with this matter, in short, let's restore the letter first, hand it to Kominsky, and see what happens next. Wang Ziyang replied.

"But how is this handwriting so familiar?" Wang Ziyang muttered quietly.
