Nan Ke was curious: "Ark, what criteria do you use to divide that specific group of people?" ”

"Remember that I deduced that Jack the Ripper was a rich man with a private carriage, and you see these celebrities in this Phantom Opera House, they are not only here to see a play, but also a manifestation of status. Since the Ripper had a private carriage, he would definitely choose a private room that corresponds to his identity, rather than sitting in an ordinary area like the general public to watch. ”

"I see, then we just need to search the private room."

"That's right. I just took a general look, and there are only about 40 private rooms, and there should be no more than 100 people among them, so it must not be difficult to search. ”

Nanke couldn't wait: "Okay, then let's get started." ”

But Nan Ke encountered difficulties at the beginning, the private room, as the name suggests, has a private space, outsiders are not easy to enter, even if they enter, it will alarm the people inside, if such a room will definitely cause a lot of commotion, and this is not in line with their secret search principle.

Nan Ke scratched his head: "I have to think of a way to enter the private room to observe them without arousing their suspicion." ”

"Isn't that the way to do it?"

Fang Zhou pointed to a waiter with a plate and said, "Just repeat the old technique." ”

They went to find the waiter, this time under the pretext that they were a private investigator, and according to the clues, they found out that there was a suspect hiding in the private room of the theater, and they needed to enter the private room without arousing suspicion, so they needed the help of the waiter.

At first, the waiter was naturally very reluctant, but as the ark took out a thick stack of star elements and placed them on his plate, he changed his mind.

Sure enough, in any environment, even in the game, money is very useful.

......

The waiter took the money and secretly took Fang Zhou and Nan Ke into the dressing room, changed into two sets of waiter uniforms, and then they entered the private rooms in turn with drinks under the pretext of delivering drinks.

Of course, these drinks were purchased by the Ark at its own expense. But in order to get to the bottom of the case, this is all due diligence.

......

After entering the private room, when the waiter delivered the drink to the customers in the room, the Ark was observing whether the information of the people in the box matched the close-up speculation of Jack the Ripper:

Male, age, between 30 and 45 years old, height: between 1.67 and 1.72 meters, with scars from the Ark wound on his leg and lesions or scars on his left abdomen.

It took them nearly an hour to talk about the more than 30 private rooms to see them one by one, and in each of these private rooms, there are men, and those who meet the height and age are probably one out of every three people who meet the standards.

After turning around, they found that there were as many as 30 people who met their initial standard goal.

They also need a different approach to further narrow down the suspects.

In the past, when I went into the private room to deliver drinks, it was just a screening of their age and height, which were two external conditions that were easier to observe. And there are two other conditions, which they do not use: one is that there is an injury or disease in the abdomen of the leg, and the other is left-handedness.

These two aspects are not easy to observe, and some special means are required.

......

After that, several people discussed, and after adding a sum of money to the waiter again, he agreed to continue to cooperate.

They went into the kitchen again, prepared dozens of glasses of wine, and then carried them to the thirty target rooms in turn.

They chose wine for a reason, and if it was something like a fruit snack, the maids who accompanied them might feed it, so that they would not be able to use their hands at all, and would not be able to observe their usual hands.

And if it's juice or something. They may have the maid serve to drink through a straw and will not use their hands.

But wine should not be drunk through a straw, which is the most ceremonial thing, and the aristocracy has always attached great importance to ceremonial matters.

But what the Ark didn't know was that even if they wanted to, they couldn't drink it with a straw, because the straw had just been invented by the Americans in the same year, in 1888.

Although straws have been invented at the moment, it will be some time before they become popular.

......

Different from the water delivery just now, this time the waiter put down the wine and said according to Fang Zhouding's words: "Honorable sir, this is the latest wine ordered by our boss, it has not been officially sold, you are the most honored guest in our boss's heart, so the boss specially instructed me to bring it to you and let you taste it before everyone... He wants to know your opinion at the first time. ”

People are vain, these celebrities are no exception, their vanity is even stronger than ordinary people, under the waiter's fanciful touting, they are full of vanity, and they will not refuse, but will take the wine glass to taste it, and then make a fake evaluation, although this is just some ordinary wine, but it still makes these nobles taste a different taste.

The waiter, on the other hand, pretended to be careful about the record, but in fact he didn't remember anything.

......

But it didn't matter, when they took the glass, it was what the Ark wanted.

When people pick up things, they will subconsciously use their dominant hands to pick them up, especially things like wine glasses.

And by the action of catching the wine glass, you can tell whether they are right-handed or left-handed.

After some investigation, the ark discovered that only two of the thirty men had their left hand.

Nanke: "Okay, now there are only two people left, but how do we find out who is the real Jack the Ripper from those two people?" ”

But Fang Zhou waved his hand: "It's not two people, it's three people." ”

Nan Ke was puzzled: "No, I remember very clearly, just now there were indeed only two people who took the wine glass with their left hands. ”

"It's true that there are two people who use wine glasses in their left hands, but when I was in private room 19, I noticed that when the person in the private room took the wine glass, he first moved his left hand slightly, and then took the wine glass with his right hand."

"You're saying he's deliberately hiding the message that he's left-handed?"

Fang Zhou nodded: "I think so. ”

"Is he Jack the Ripper?"

"Not necessarily, when the theater is over, we can test them again, and then we should be able to tell who the real Jack the Ripper is."

On the other side, the waiter who assisted them had already run away with a sum of money from the Ark, after all, the nobles he had just deceived were easy to settle accounts here.

And he took the money given by the ark to go to the United States, and he could live a very good life.
