While thinking, I have returned to the upstairs, as soon as I entered the door, I saw Meng Rong and Lao Dao were waiting for me at the entrance, Meng Rong leaned against the wall, she took a tissue and wiped her tears, as soon as I entered, she peeked at me, and saw that I was also looking at her, so she lowered her head and sobbed softly.

I wasn't in the mood to pay attention to her performance, the old knife asked me how I was, I raised my hand to stop him from talking, and I first went to carefully check the windows of each room in Lin Sen's house, and also observed the walls in the room.

I told Lao Dao that I had gone down in vain, and I didn't see any suspicious people coming down from the stairs.

The old knife will naturally guess that I am not without new discoveries at all, and he only needs to think a little to understand why I am silent.

Then the two of us sent Meng Rong downstairs, took a taxi on the street, and let Meng Rong go home first.

Meng Rong was naturally reluctant, but Lao Dao had already said in advance that she could not participate in the specific investigation, and it was already an exception to let her follow to the scene of Lin Sen's house, not to mention, I said that we have now completed the on-site investigation at Lin Sen's house, so she has no reason to follow us anymore.

Before sending her to the bus, I handed Meng Rong a business card and told her to call me if she made any new discoveries.

Taxi away.

The old knife snorted and said, "You can tell me now, what did you find?" ”

I nodded, and at the same time walked towards the building where Lin Sen's family lived: "Let's go back to the scene and talk as we go." ”

I told Lao Dao that I chased downstairs just now, and I didn't see anyone coming out of the building, but behind the building, I saw someone driving Fang Zhe's car away, and suddenly I felt that something was wrong, and looked up at the building, but saw that Lin Sen's house was connected to the window of the bathroom in the living room, close to a downpipe.

Then I went upstairs and took a closer look at the torn seal on the bathroom window of Lin Sen's house, which had been ripped open from the inside out. As for the door, when we came in, I kept an eye on it and quietly painted it with an oil-based pen on the doorknob.

The door was indeed opened from the inside, and when Meng Rong was sent away just now, I deliberately handed her my business card, in order to see if there were any traces of an oil-based pen on her hand.

The old knife said: "Then there must be one?" ”

I nodded.

The old knife also nodded and said, "When you checked the door and bathroom window, Meng Rong showed a nervous look, and when she saw me looking at her, she pretended to be calm. That's when I was suspicious. Now, combined with your judgment, I suddenly figured out a strange thing. ”

I pretended not to understand: "What's weird? ”

The old knife narrowed his eyes, and the corners of his mouth smiled: "The mystery of the secret room." ”

"However, I saw that your kid was walking around the house just now, I'm afraid you've already found the answer to the mystery, right?" The old knife continued.

We entered Lin Sen's house again, and I opened the locker in the bathroom connected to the living room directly in front of the old knife, and then made a "it's your turn" gesture to him.

When the old knife saw me like this, he naturally understood. I saw him knocking on several inner partitions of the locker, listening for a while, and then finding the right place, a partition was found by the old knife to the mechanism, unloaded, inside, is a narrow secret room of only one and a half square meters!

Although the secret room is empty, its existence has said it all.

The old knife pointed to the secret room: "I thought it was strange at the time, this bathroom is repaired on the edge of the living room, and the wall in the middle is not a load-bearing wall, why is it so thick?" And the humidity in the bathroom is very high, and most people will not repair a locker in the bathroom...... Sure enough, it's weird. ”

Now, Lin Sen's secret room suicide case has been cracked by us.

Someone must have killed Lin Sen, and then made that terrible appearance, and the murderer himself locked all the doors and windows of the entire room, creating the illusion of a secret room. Then he hid in this secret room, waited for the police to leave, and then went out of the bathroom window and climbed down the downpipe.

Lao Dao sneered: "Looking back, Meng Rong has been inducing us since she met us in the café and asked us to return to the scene to investigate. She opened the door herself, and then pretended to see someone running through it, attracting our attention so that the real killer could escape through the bathroom window. From this point of view, the death of Lin Sen and Fang Zhe, even if Meng Rong is not an accomplice, will definitely not be able to escape the involvement! ”

After a pause, Lao Dao's face suddenly stiffened again: "But there is another question here: how did Fang Zhe get into this room?" ”

We carefully checked before entering the house, and the police seal on the door was indeed torn open, but there was a doorman at the entrance of the community watching, and there was a 24-hour convenience store opposite, so it was very difficult and risky to bring in a body of Fang Zhe (or Fang Zhe who had been knocked unconscious). Anyway, if I were the murderer, I wouldn't have chosen this way.

I said, "But if you don't come in through the gate of the complex, then the only possibility of entering this room is through the bathroom window." ”

The old knife checked a few windows, shook his head and said that he had found no scratches on the rope, and no footprints, all of which had been wiped clean.

"No, no, no...... More than just these two possibilities – there must be another way! The old knife first said to himself, then suddenly stomped his foot and scolded: "Fuck, we all called Meng Rong this little girl!" ”

I asked the reason, and the old knife sneered: "Fang Zhe was not killed or stunned at all, he climbed up by himself!" Fang Zhe's death was not carefully premeditated, but an accident. A good one will be calculated! ”

When the old knife said this, I also reacted.

Lao Dao said: "Now it is certain that the person who is following us is Fang Zhe. And Meng Rong said that the car belonged to Fang Zhe, and she said it in a hurry. And do you remember, after we said that we were going to the scene to have a look, Meng Rong must have asked to go with us, and then ran to the toilet to let us wait for her? ”

I nodded: "That's right, she must have gone to call the murderer, and then tried to trick Fang Zhe into going to Lin Sen's house, and then hid in the toilet for so long, in fact, she was delaying time, so as to give the murderer a gap to kill Fang Zhe." But we still arrived quickly, the murderer didn't have time to escape, so Meng Rong deliberately banged on the door to remind the murderer inside to leave, and when we were about to check the bathroom, we said that we saw someone rushing out of the room, and we were stunned and forced to put on a good show, in order to lure us away and help the murderer escape. ”

Fang Zhe was actually able to be tricked into entering Lin Sen's house by himself, you know, this is a murder scene! I think that's right, the murderer must be someone Fang Zhe knows very well! It could even be one of his five friends!

Meng Rong was with us at the time, there was alibi evidence, Lin Sen was dead, naturally it was impossible, the rest were Luo Xing and Liu Yao!

Liu Yao is a woman, could it be Luo Xing?!

I told the old knife about this idea.

"Let's go, let's go find Luo Xing!"

Lao Dao immediately went downstairs with me, took out his mobile phone again, and dialed a number. I know that he must have called Li Yi to ask for the address of Luo Xing's current residence.

Sure enough, I heard Lao Dao say into the phone: "Hey, stinky fish, where did you settle Luo Xing, give me the address!" Don't blow it to me, 100,000 in a hurry...... What, you're heading over there now? Address, address! The alley where the blind man lived before? Isn't that place about to be demolished? Second floor, right? Okay, got it. ”

The old knife was about to hang up the phone, when he suddenly put the earpiece close to his ear again, and his footsteps stopped, his face was excited, and he yelled into the phone: "What's wrong?" What's going on over there? Stinky fish! Stinky Fish—"

I hurriedly asked him, what's wrong? The old knife had a calm face: "The stinky fish yelled on the other side of the phone, 'What the are you doing here!'" Then there was a cry of pain from the stinky fish, which seemed to have been attacked by someone, followed by the sound of the phone falling to the ground, and then, the stinky fish screamed again, and then there was a loud noise from the phone, and the call was cut off. The old knife finally made a judgment, "On the stinky fish's side, something must have happened!" ”

I was shocked: "Someone smashed the phone?" ”

The old knife said: "I don't know." But I have a bad premonition! Let's go! ”

I also knew that the matter was urgent, and the situation on the stinky fish's side must be extremely bad, and at that moment, Lao Dao and I almost fought the speed of a 100-meter race and ran downstairs.

When he got downstairs, Lao Dao's car found that someone had pierced the tire, and Lao Dao scolded again: ", it must be Meng Rong who doesn't worry about us, and when she comes back to the scene, she sees that our car is still there, she must know that we must have guessed something, so she punctured Lao Tzu's tire!" ”

The old knife scolded a few words, and his face became more and more ugly, almost iron-blue.

I also understand that things are going to be bad! Meng Rong waved this hand, intending to delay time. For whom is she going to cover and for whom is time delayed? Just think about it on your toes!

From this point of view, something big must have happened to Li Yi's side!

It also happened that at this time, a taxi passed by, but from the front window of the taxi, the red light carrying passengers was off. I waved my hand and shouted to stop, but the taxi ignored me, and drove straight away, seeing that I was about to miss, the old knife scolded my mother, and rushed to the middle of the street, and opened my hands to stop the taxi.

The taxi driver was caught off guard and slammed on the brakes, and a piercing friction sound sounded, and the wheels of the taxi dragged out four long brake marks on the ground, and the front cover of the car was only a few centimeters away from hitting the knee of the old knife!

", are you crazy? Looking for death?! The taxi driver poked his head out and cursed.

Lao Dao ignored the scolding of others, and only shouted at me: "Quick, get in the car!" ”

As he spoke, the old knife had already opened the passenger door and sat in. I didn't care about it so much, so I followed the example of an old knife, opened the back seat and sat in.

The original passenger of this taxi was a lady sitting in the back seat, dressed as an OL (female white-collar worker) in her thirties, who was frightened by the old knife's forced stopping, and her face was white, and after I got in the car, she was even more frightened, and subconsciously wanted to open the door and get off.

But she sat on the left, and according to the custom of the taxi industry in China, the door on that side is usually locked for safety.

Sure enough, the lady tugged on the car door a few times, but she still couldn't open it, and in a hurry, she actually whimpered and cried.

"Hey, what are you guys doing here? Don't see anyone in my car? "The taxi driver is a bald fat man of about forty, and he is also a little scared by the old knife and me at the moment, but he is finally calmer than the female passenger in the back seat, "You, don't mess around, we have walkie-talkies, and we can call the dispatch center ......to call the police at any time."

But seeing the old knife quickly took out a hundred-yuan bill from his pocket and handed it to the driver, the driver saw the old knife take out the money, and was a little stunned: "This, what is this for?" ”

The old knife accompanied the smiling face: "I'm sorry, buddy, the two of us really encountered a hundred thousand urgent things!" You take the money first, and when you get to the place, I'll give you another hundred. The old knife said, and stuffed the money into the driver's hand.

The driver looked at the money in his hand, his face was a little suspicious, and a little shaken, he looked at the crying female passenger in the back seat, and hesitated again: "But...... I already have a guest here. ”

"I'll get out of the car! I get off! I'm not going to ride anymore, you let me go down......" The OL almost screamed.

The taxi driver had no choice but to open the safety on the left door, and the woman got out of the car as if she had fled.

"Brothers, you really don't plan to do anything illegal, do you?" The bald fat driver is still a little wary.

"What are you kidding, do you think we both look like robbers?" I say.

"Mao'er Lane, Jinjiang 2nd Road." The old knife touched another hundred and slapped it on the front desk of the car, "Drive." ”

The driver's fat face twitched a few times, and finally gritted his teeth, reached out and grabbed the money, and said "Go." "Hit the gas.
