The door at the main entrance of the mountain temple was very heavy, and Lin Lei did not touch it directly with his hands, but looked at it with his eyes. Pen, fun, pavilion www. biquge。 info

The most taboo thing in the on-site investigation of a criminal case is to touch it randomly, and of course Lin Lei would not make such a low-level mistake.

Lu Yun was still cautious in taking pictures, and the result of Lin Lei's final inspection was that there was nothing abnormal about this door, it was locked from the inside.

The investigation in the first step unmistakably showed that the main entrance and side doors of the mountain temple were locked from the inside, and Lin Lei had personally inspected them, and there was no "false appearance" or "fishing line mechanism......

"It's really a secret room killing!" Lu Yun frowned, "Lin Lei, this is too evil, isn't it, a once-in-a-century secret room murder, why was it encountered by us?"

Lin Lei smiled bitterly and shook his head: "Who knows?

Lu Yun immediately glanced at Lin Lei: "Hehe, hehehehe......"

"Before the Gunma Prefectural Police come here, we have a few more places to investigate. Lin Lei frowned slightly, "After all, the bedroom where Master Foolish Hatred died, not a secret room, but the entire mountain temple is a secret room." In this case, there are many possibilities, such as—"

Lin Lei didn't continue, but Lu Yun answered: "For example, 'falling from the sky'?"

Lin Lei glanced at Lu Yun appreciatively, and asked with a smile, "You also noticed?"

Lu Yun nodded and said, "Hmm." In order to determine that the temple is a secret room, it is necessary to rule out the possibility of climbing out of the wall. And, if I'm not mistaken, one of the five college students was a pole vaulter. The three-meter-high fence may seem high, but for pole vaulters, it's nothing at all. ”

Lin Lei's eyes looked at the ground near the wall: "Let's go, let's see if there are any traces on the ground." ”

"Hmm. Lu Yun followed behind Lin Lei, still holding up her mobile phone to take pictures.

There are no footprints in the entire courtyard, this puzzle has been solved by Lin Lei - in fact, it is not a puzzle, and Lu Yun also knows it.

Heavy rain.

Yes, yesterday it rained heavily for a day and completely washed away the footprints.

Last night's heavy rain stopped at twenty-two o'clock, and combined with Lin Lei's preliminary judgment of the time of the death of Master Foolishness, it can be inferred that the murderer did not leave no footprints, but that the footprints were washed away by the heavy rain.

Of course, the murderer can enter the Yamanakaji Temple normally through the gate, but it will be very troublesome to get out.

Set up such a secret room, and then how to get out?

Circumvention is a possibility.

The walls of Yamanakaji Temple are more than three meters high, and this is not an ordinary wall, and it is absolutely impossible to climb over such a high wall without leaving any traces.

There is also a possibility, which is what Lu Yun said about "pole vaulting".

But with the help of tools, such as bamboo poles, it is possible to "jump" out without touching the fence.

The men's pole vault world record is a little over 6 meters, and the fence is only 3 meters, which is obviously not a difficult task for professional athletes at all.

There is also a problem with this, and that is traces.

In the case of pole vaulting, in this kind of soft ground, the pole will definitely leave a small hole in the ground with the last jump.

This small pit is not as easy to wash away as footprints, and most of them will leave clues.

Lin Lei is now looking for this kind of clue.

First, are there any traces of climbing the fence?

Second, on the ground near the wall, are there any "small pits" left by "pole vaulting".

In the case of "pole vault", the murderer is obviously Shiho Tanabe. Only as a pole vaulter can he complete this murder modus operandi in a closed room.

Even if an ordinary person was given a bamboo pole and told to jump over a three-meter-high fence, it would be almost impossible. Pole vaulting has a very complex technical essentials, and you can't even complete the take-off without professional training......

Lin Lei inspected the wall and the ground near the wall meter by meter, and Lu Yun kept following behind him to take pictures.

It wasn't until the entire courtyard wall and the ground near the fence were examined that there were no signs of climbing, and there were no small pits like the pole vaults.

There are many places on the fence with cobwebs or creepers and other plants, and if there are traces of climbing, you can see it at a glance.

"It didn't come out of the wall-" Lin Lei's brows furrowed more and more, obviously this case was rapidly approaching the "murder in a closed room".

Lu Yun frowned slightly, and said in a low voice: "Let's go outside and see, are there any traces outside the wall?"

"Well, the outside is also important, let's go!"

Lin Lei nodded, and the two walked out of the mountain temple through the side door.

However, when Lin Lei turned around along the outer wall and returned to the original point, he found that there were no traces of the outer wall and the surrounding area......

That's weird......

The murder case of Master Foolish Anger in the Mountain Temple is really a case of murder in a closed room!

Lin Lei took out a little bit of eight water bays from his pocket, lit it, and quietly pondered various possibilities.

"Lin Lei, I think the murderer must have used some kind of trick to erase the traces of how he got out of the mountain temple. Lu Yun said what she thought in her heart.

Lin Lei rubbed his temples and was noncommittal: "The police from Gunma County will be here soon, let's go back and talk about the analysis of the case." Now you go back to Yamanakaji Temple and take a video of the places you didn't shoot just now - remember to leave no dead ends, and record everything into a video. ”

Lu Yun nodded: "I know." ”

Lu Yun entered the Yamanaka Temple through the side door again and began to record a video.

It's the only path outside Yamanakaji. Lin Lei frowned, took out a point of eight fond, and lit it ......

This case is very obvious from the current situation, it is the so-called "murder in a closed room".

Is there murder in the secret room?

It is a rare occurrence in a hundred years in China, but I didn't expect to encounter two cases in a row when I went abroad.

In general, there are three types of secret room killings.

The first is the Psychological Chamber.

The previous murder in the locked room on the cruise ship "Daystar" was just a small ruse -- in terms of the method of murder in the closed room, that case belonged to the "psychological secret room".

As long as the puzzle solver is open-minded and not swayed by "habitual thinking", then the truth is often very simple.

The second is the on-site arrangement.

As the name suggests, that is, the informant at the scene of the murder or the person who followed the informant took advantage of the fact that everyone was not paying attention to the ghost trick of the secret room at the scene.

For example, if there is a small mechanism on the door lock, it can be recycled when people are not paying attention.

Or in some other way, to deceive the crowd......

Anyway, the secret room scene will definitely leave evidence and the key to solving the mystery, and the murderer will dispose of these at the scene to complete a so-called "secret room".

This situation is common in detective novels, but it doesn't work for Lin Lei.

From the time he didn't get close to the temple in the mountains, Lin Lei realized that something might be wrong inside the temple

The person who knocked on the door was Lin Lei, and it was Lin Lei who pushed the door.

Those five said that they hadn't touched the door lock at all before Lin Lei knocked on the door and pushed the door, how could they possibly complete the on-site arrangement?

The third possibility in a closed room homicide is that the killer used some bizarre modus operandi.

For example, the most common "fishing line" secret room murder in this anime Conan is a strange technique.

Usually, the use of bizarre methods to complete the murder of a locked room rarely appears in reality.

Especially in China, there have been so many murders in the past few decades, and there are almost no strange secret room murders.

But in Ben, it's a different story.

It is said that this is a globally recognized kingdom of reasoning, and many people are keen on mystery novels and mystery film and television dramas. Under this long-term subtlety, there have been many "closed room murder cases" with amazing methods.

Now this case is likely to be the murderer's strange method of arranging the entire temple into a secret room.

What is the method?

Lin Lei took a deep puff of his cigarette and fell silent.

At this moment, Lin Lei heard footsteps.

There was more than one person's footsteps, at least seven or eight people!

Lin Lei turned his head to look at the only mountain trail, and sure enough, a team of policemen appeared in Lin Lei's sight.

The policemen came to Lin Lei, and a criminal policeman in his thirties led by him asked sharply, "Who are you?!"

Lin Lei glanced at the officer, and saw that he was of medium height, with a big back, and was wearing a blue police uniform, indicating that the lower part of the badge of the police rank was yellow, plus a bar on the left and right.

Lin Lei was very familiar with this police rank, and immediately knew that this officer's police rank was made up by the police department.

It is said that the police rank of this police is more cumbersome, and the police rank of Twilight Thirteen, who often appears in the Conan anime, is the police department, and Miwako Sato is the police department.

To put it simply, the police department can be understood as the deputy police department, and the position is the position of the beautiful police officer Sato in Conan.

This rank is not very small, if you have to use Huaxia's standards, it is probably similar to Huaxia's low-level superintendent rank. In terms of administrative functions, it is roughly equivalent to the instructors and instructors of the Huaxia county-level public security bureau.

Since the deputy police officer said, "Who are you?" as soon as he opened his mouth, it means that he has already asked the five college students -- it seems that he does not think that Lin Lei is an ordinary Chinese person......

Or, it is also possible that Lin Lei is the murderer.

Otherwise, why do you leave everyone else apart and just stay at the scene of the murder by yourself?

Lin Lei smiled slightly, took out his ID from his pocket, and handed it to the police officer who interrogated: "My name is Lin Lei, and I am an ICPO agent. ”

"ICPO?-!" the officer exclaimed, his eyes widening.

He immediately took Lin Lei's certificate, read it carefully, and then handed it back to Lin Lei, and his tone was very respectful: "Officer Lin, I'm Yoichi Miki, a county police officer of Gunma County, please take care of me when we meet for the first time." ”

After knowing that Lin Lei was an Interpol policeman, Officer Miki's attitude was very humble. And the ordinary policemen behind Miki were even more round-eyed, looking at Lin Lei incredulously.

The rank of these ordinary police officers is very low, usually patrols and the like, with their rank, they may have never seen ICPO police!

Lin Lei smiled slightly, glanced at Officer Miki meaningfully, and said lightly: "Well, I was originally invited by the Tokyo Metropolitan Police Department to come and assist them in arresting them-well, it's inconvenient to tell Officer Miki the specific facts of the case......"

"Ahh......h

Lin Lei wanted to reply to him, "What do you understand", but in the end, he thought about it and just continued to smile faintly.

As we all know, the country is divided into 1 prefecture (Tokyo), 1 province (Hokkaido: Hokkaido), 2 prefectures (Osaka Prefecture, Kyoto Prefecture: Kyoto), and 43 prefectures (similar to the miniature version of the province of Kako).

The Tokyo Metropolitan Police Department is the highest police agency in Japan, and it is about the same as the Ministry of Public Security in China.

Of course, in addition to managing all police in the country, the Tokyo Metropolitan Police Department is also responsible for the security of Tokyo itself.

To put it simply, the Tokyo Metropolitan Police Department is equal to the Huaxia Ministry of Public Security and the Imperial Public Security Bureau - well, that's it.

Gunma Prefecture is only one of the 43 prefectures in the original area, and the administrative level is relatively low.

How could Officer Miki of the Gunma Prefectural Police Department not be shocked when he heard that Lin Lei was actually an ICPO agent invited by the "top-level" Tokyo Metropolitan Police Department to assist in the arrest of criminals?

In fact, Lin Lei did not talk nonsense, after the "Daystar cruise ship incident", the Tokyo Metropolitan Police Department did issue a notice to the Interpol Pacific Rim Division to assist in the investigation......

Even the FBI of the United States has issued more than 2,000 pages of investigation notices, and Lin Lei's identity is very powerful.

Moreover, Lin Lei came to say that it was an order personally given by the superior Superintendent Su Ke. If, procedurally speaking, Lin Lei appeared anywhere in the book and investigated any person, it was a problem.

"Officer Lin, are you assisting us in protecting the scene?" Officer Miki said to Lin Lei with a smile.

Since Lin Lei is a police officer of the ICPO, it is absolutely impossible for him to be a murderer, and Lin Lei has nothing to do with the Master of Foolishness. The only explanation that Lin Lei left at the scene was that the "Brotherhood International" assisted in protecting the site.

Lin Lei bowed slightly: "Officer Miki is really a smart person, it is true." ”

After a pause, Lin Lei continued: "Check the surveillance of the Cloud House Hot Spring Hotel later, if no new suspects appear, I suspect that the murderer is among the five Ota University students......"

Although Officer Miki is kind and polite to Lin Lei on the surface, he is also a person with brains - whether what Lin Lei said makes sense or not, he still needs to investigate it himself.

Therefore, Officer Miki did not answer Lin Lei's words, but said to Lin Lei: "Officer Lin, the matter of the on-site investigation will be handed over to our Gunma County Police." You can wait at the hostel, I will ask you if there is a need. ”

At this moment, Lu Yun also came out of the side door of the Mountain Temple......
