After discussing with the housekeeper for a while, Chang Wen and the housekeeper both feel that there is no way to start the next step of investigation, and they are in a desperate situation.

Who is this insider?

Chang Wen went to the earth investigation company. As soon as Wang Xiaoman saw him, he said with a smile: "little brother, you look sad. I know that you have encountered a problem again."

Chang Wen tells Wang Xiaoman: Lin Xiaozhen even knows that she and Dousha have different beds in the same room. She makes a shop on the floor every day. He seriously suspects that there is a ghost in the villa of Regal Garden. However, after checking for a long time, she finds nothing.

Wang Xiaoman also felt puzzled and said: "little brother, you and Dousha share different beds. This is the privacy of privacy. Normally, no one will know except you two. It's really amazing that this kind of secret thing has spread out."

Chang Wen sighed and said, "sister Wang, I really don't have any moves. I've come to ask you. Do you think there is a ghost in the villa of Regal Garden?"

"It's hard to say that, little brother. If you think about it carefully, have you ever told anyone about your different bed with Dousha?"

"Sister Wang, do you want me to tell someone about this? It's impossible. I... my wife and I have been married for three years, but I have never been in bed with my wife. Now, soymilk forces me to sleep with Dousha in the same room, but I still have to make a shop on the floor. If this kind of thing spreads, people will surely say that I am a loser among the losers. "

Wang Xiaoman thought about it and asked, "you have no face to tell it. Will Dousha reveal it unintentionally?"

Chang Wen affirms: "Dousha will never say it. Now dounai forces her to share a room with me. If she says it, once it comes to dounai's ears, it will cause great disaster. If dounai knows, she will sit in my bedroom with Dousha and supervise us to sleep in the same bed. Don't say, dounai can do anything."

"If you and Dousha don't talk about it, maybe there is a ghost in Regal Garden Villa. This ghost will come to your bedroom door at night to peep or listen to the corner. I think: your floor must be at the door. If you listen to the corner, you can tell from your voice that you two are not sleeping in the same bed."

"Then... Who would listen to the corner?"

"Little brother, I think if there is a ghost in Regal Garden Villa, then he will continue to listen to the corner and spy on the new situation, so as to report to Lin Xiaozhen at any time. In fact, as long as you secretly install a surveillance camera on the second floor, you can also catch the insider in the corner. "

"Ah! Why didn't I think of this move? Sister Wang, you have experience. Fortunately, I came here today to ask for advice. Otherwise, if I want to break my head, I can't come up with a good move. "

"Later, I'll let big head and thin monkey disguise themselves as employees of the power company and go to the Regal Garden Villa to check and repair the wiring. By the way, I'll install a surveillance camera so that you can watch the situation outside the door on your mobile phone," Wang said

In the afternoon of that day, big head and thin monkey dressed up as maintenance personnel of the power company, went to the Regal Garden Villa and pretended to repair the line. A surveillance camera was installed on the second floor, facing Chang Wen's bedroom door, and the monitoring range reached 180 degrees.

Big head operated on Chang Wen's mobile phone for a while and told him: "boss Chang, I set a time for you. From ten o'clock every night to six o'clock the next morning, as long as someone comes near your bedroom door, it will send out a drop by drop alarm. As long as you turn on your mobile phone, you can see the monitoring situation."

Chang Wen tried it, the lens is very clear.

"Big head, I didn't expect you to do this again."

"Ha ha... Boss Chang, as investigators like us, it's the most basic to understand the monitoring knowledge."

The monitoring probe installed in Regal Garden Villa is very hidden. It is installed on the ceiling lamp on the second floor. From the appearance, it looks like an ornament of the lamp itself.

On the night of the third day, Chang Wen was awakened by the alarm of his mobile phone. He quickly turned on his mobile phone and was surprised to find a black shadow at the door of his bedroom. Looking at the black shadow, it should be the cook.

The second floor is dark, and the camera in the surveillance is also vivid, but the waist of the bucket of the cook still exposed her.

The cook put her ear to the door of Changwen's bedroom, and seemed to be listening.

After about two minutes, the cook left Chang Wen's bedroom door and entered a guest room on the second floor.

There is also an empty room on the second floor, which has ready-made beds and furniture. This room is reserved for guests, so yangjiaopai cleans this room every day.

Chang Wen is a little surprised. What's the cook doing in this room in the middle of the night?

Does the cook want to sleep in the guest room on the second floor?

After about half an hour, the cook came out of the guest room, went downstairs and seemed to return to her bedroom.

Early the next morning, Chang Wen got up and went to the small garden. He knew that the housekeeper would exercise in the small garden every morning.

When the housekeeper saw Chang Wen coming, he asked with a smile, "boss Chang, why did you make an exception to exercise today?"

"Housekeeper, at one o'clock in the morning, the cook went to the second floor. She was at the door of my bedroom and put her ear on the door. She seemed to listen to the corner of the wall. After listening for about two minutes, she went into the guest room on the second floor. After another half an hour, the cook went downstairs."

The housekeeper was surprised and asked, "boss Chang, have you seen clearly?"

"Although it's dark on the second floor, I can still recognize the waist of the kitchen pail. Besides, I'm familiar with the way the kitchen pail walks. I'm sure that the black shadow is the kitchen pail, and I can't be wrong."

The housekeeper murmured suspiciously: "the cook went to the second floor to listen to the corner, and it was one o'clock in the morning. Is she an insider? Even if it's a ghost, you and Dousha fell asleep at that time. Does she want to listen to dreamtalk? Generally speaking, if you want to listen to the words in the corner, it should be when you and your wife are just sleeping. Maybe they will say something in secret. "

"The question is: why does the cook want to run to the second floor and put her ears on my door? This action is obviously listening to the corner of the wall, and why does the cook run to the guest room?"

"It's really beyond my expectation. I didn't expect that the cook should be an insider. If she is, she must know that you are sleeping on the floor through the conversation between you and Dousha."

Chang Wen looked at the kitchen. He saw that the cook was busy in the kitchen. Looking at her look, it seemed that she was not very happy. Her face was covered with clouds, just like the sky before the rainstorm.

Perhaps, she listened to the corner for a long time last night, and got nothing, so she was very disappointed.
