Although there are many residents in this neighborhood, they are all from the middle and lower classes of the city who can hardly afford a carriage.

From finding a person to finding a carriage, the job suddenly became much easier.

It didn't take long for Lestrade's order to be issued.

The Scotland Yard patrol officer responsible for searching the neighborhood brought back the results:

"We found a total of 8 carriages."

"These are all vehicles that were intercepted from the road after we blocked off the block - according to them, they just happened to pass by this block and had no idea what was going on here."

"Officer Lestrade, as you command:"

"We have brought these carriages and their owners here together, and I invite you to take a look."

"good!"

Lestrade nodded with satisfaction.

He looked at the carriages that were gathering in front of him under the surveillance of the police, as well as the nervous and bewildered carriage owners and drivers.

Then he turned to Lin Xinyi and cast an expectant look.

Lin Xinyi naturally took over the command and continued to ask the patrol officer in charge:

"Are these carriages covered with Persian carpets?"

"Well..." the police officer thought for a while: "They all seem to have carpets, but we didn't pay attention to distinguish whether they were Persian carpets or not."

"Okay." Lin Xinyi continued to ask: "How many of these eight vehicles can only find one 'occupant'?"

A gentleman who owns a carriage usually doesn't drive it himself, so he has to hire a driver.

So if you find a carriage, theoretically you should find at least 2 corresponding passengers.

The patrol officer's answer was:

"There are no passengers in these eight carriages, and only the driver can be found."

"Some of them said they were drinking alone outside at night and were getting ready to drive back. Some said they were driving to the bar to pick up a job and hadn't picked up the customers yet."

"Anyway, they were the only ones in the car - and none of them had a solid enough alibi."

"I understand." Lin Xin nodded:

The Jack the Ripper they saw in the "opening CG" was only one person.

This may be the game designer hinting to the players that the mission target "Jack the Ripper" refers to a specific person, rather than an organization or a gang.

And think from the experience and logic of reality:

Serial killers like Jack the Ripper usually commit their crimes alone, and there are few records of gang crimes.

Because perverts like this like to dig out intestines and dig out internal organs...

It is really difficult to find like-minded accomplices who can commit crimes with them.

Originally, Lin Xinyi wanted to further narrow down the focus of the investigation based on the number of passengers on the carriage.

Unexpectedly, there was only one driver on each of these eight carriages.

"I'm afraid this is not a simple coincidence..."

"It's a puzzle that the game deliberately created for me, an 8-choose-1 puzzle."

Lin Xinyi was even more certain that he had correctly guessed the question maker's thoughts and found the right direction to solve the problem.

Then he calmly ordered the police officer:

"Bring all those car owners here -"

"I want to have a good chat with them."

The passengers of the eight carriages, as well as the carriage drivers, were quickly invited to come forward by the patrol police.

Confusion was written on all their faces.

No one looks like a bad person.

Lin Xinyi did not ask any questions, but looked at them carefully:

The faces of these people were all clean, and there were no suspicious stains on their hands or clothes. They did not look like murderers who had just killed someone at night.

"Master Lin..."

When I saw Lin Xinyi, he didn't show off his strength like a master, nor did he ask questions like a police detective.

Officer Lestrade couldn't help but asked with some concern:

"Didn't Ms. Elizabeth's ghost tell you which of these eight people was the murderer?"

"..." Master Lin's face darkened: "No."

"We have to solve this problem ourselves."

"This..." Officer Lestrade became increasingly worried: "Now the suspects are here."

"But after all, there are eight people here."

"How do we find Jack the Ripper among them?"

"besides..."

There was another sentence he hesitated to say.

That is...Is Jack the Ripper really among these 8 people?

Is what the master just asked from the dead person accurate?

In fact, Lin Xinyi himself was not sure about this.

If he were writing an autopsy report for Ms. Elizabeth in reality, he would only write this:

"Two strands of silk and three strands of wool were extracted from the skirt of the deceased. It is speculated that he had come into contact with textiles containing silk and wool components during his lifetime."

This is the only way the report can be written.

Even if it is stated as "speculation", it must still be written vaguely as "textile made of silk or wool".

It must not be written as specific items such as "carpet" or "sheet".

Because no one can guarantee that this "silk-wool fabric" must be a carpet - it can only be said that it is more likely to be a carpet.

Writing this way contains elements of reasoning and guessing, which is neither scientific nor rigorous enough.

But because this is a game world, and there is no other way to pass the level.

Lin Xinyi could only boldly use his imagination and guess the truth based on the few clues he had.

He was also not sure that his reasoning, which he could barely establish by trying to figure out the mind of the person who asked the question, was 100% correct.

but...

"I can't be 100% sure that the murderer is among these eight people."

"But if Jack the Ripper is really among these eight people... I have a way to find the real murderer among them!"

A confident smile appeared on Lin Xinyi's lips.

"oh?"

Officer Lestrade widened his eyes curiously:

"Master, what other 'magic' do you have that you don't use?"

He seemed to live like a servant, calling "master" whenever anything happened.

But this time "master Lin" did not disappoint him:

"Magic..."

"In this day and age, that's right!"

Master Lin smiled slightly and slowly read out an unfamiliar and difficult word:

"Luminol."

"Officer Lestrade, have you heard that?"

"Luminol?"

Lestrade chewed this extremely unfamiliar word carefully.

The police officers also looked at each other in confusion.

Everyone was silent for a while, and then someone asked cautiously: "What kind of spell is this?"

"..."

Master Lin's face darkened:

"No, this is an energetic organic compound."

"If 'luminol' sounds hard to understand."
