"Secret room." Jian Jing yawned, feeling sleepy. "Do you think this secret room belongs to an agency?"

Ji Feng said, "No." He has been in the industry for so many years, and has only encountered a few cases of murder by agencies. The production method is quite simple, but even so, there was one unsuccessful attempt.

It can be seen that the tricks of agencies to kill people are cool enough in novels, but the success rate in reality is very low.

Jian Jing said, "I thought so too, so at the beginning, I was thinking about whether this secret room could have been caused by an accident."

"No, the blame on Tan Hao must have been prepared long ago." Ji Feng remembered something and said hurriedly, "I checked his medical records. Three years ago, he was hospitalized for anaphylactic shock. Because of timely treatment, there were no sequelae, and it has never happened again since then."

Jian Jing asked, "What is the allergen?"

"I don't know, it should be something rare." He said, "I arranged for him to do a test, maybe I can know the reason why he was in a coma at the time."

"Did you mention this to anyone?"

Ji Feng smiled: "It's a coincidence. The deceased had arranged a physical examination for them. He was a high-risk group. He said that he mentioned this to other people at the time, but no one took it seriously."

"So, anyone could know that he is allergic to a certain substance." She yawned again, "What about the scene?"

"Wait until the allergy test comes out, then ask them to verify." The technical investigation department is also a place where overtime is common. The evidence for this case has been collected long ago. If they are asked to review it without solid evidence, they will be beaten by their colleagues.

Jian Jing nodded hastily, half-lidded: "Even so, I still insist on what I said just now. The secret room is not like this..."

Ji Feng: "Keeping you in suspense?"

"No--" She dragged out the tone, "

I'm sleepy." "Go to sleep for a while, I'll call you when we get there." Ji Feng shook his head, thinking, Teacher Jian's endurance is not very good. Fortunately, he is a policeman, otherwise he would not be able to hold on for several consecutive nights.

Jian Jing responded, resting her head on the soft pillow, and fell asleep in a short while.

Outside the car window, the night was deep.

Ji Feng turned down the air conditioner and slowed down the car.

The street lights in the distance emitted a soft warm light, illuminating the road ahead.

About twenty minutes later, she arrived at her home.

Ji Feng parked the car in the underground garage and drove to the parking space closest to the elevator. Then he called her: "Teacher Jian, we're home."

Jian Jing woke up in a daze, yawned loudly, and had sleepy eyes and physiological tears in the corners of her eyes: "We're here, so fast."

"Go back to sleep, I'll come again tomorrow afternoon." He said.

She nodded and unbuckled her seat belt.

He didn't pull it off.

"I'll do it." Ji Feng leaned over and touched the buckle, "It's not working well."

Jian Jing asked, "Are your wounds better?"

"They're all scabby. They'll be fine in a few days." He unbuckled his seat belt and smiled at her, "Don't worry."

"Who's worried?" She complained, "You're thick-skinned. I know you won't die. Let's go."

She opened the car door and drove away.

Ji Feng looked at her back until she disappeared, then turned the car around and left. I'm too

tired tonight, let's go home and take a nap.

The next day. Seven forty.

Ji Feng was awakened by the ringing of the phone, and when he picked it up, it was Lao Gao calling. He said that the prisoner arrested yesterday confessed, and he was going to arrest another accomplice this morning.

He had to get up with difficulty, wash up hastily, put on his clothes, and rush to report to the police station.

At eight thirty, we set off. After more than an hour of surveillance, the criminal was formally arrested at ten o'clock.

The interrogation began.

At eleven o'clock, I handed over my shift to my colleague and had lunch.

I was too sleepy after lunch, so I took a nap on the table. After sleeping for about fifteen minutes, I felt better immediately and wanted to work as soon as I opened my eyes. What

caught my eye was a pair of legs.

Shiny sandals, peach-colored manicure done by a beauty salon, and a hazy matte blue dress with slightly wrinkled fabric, like a stretched cloud.

Ji Feng looked her up and down and smiled: "Can we solve the case?"

"Who said that?" Jian Jing was surprised.

"You're not going to run around when you're dressed like this." He picked up his phone and looked at the unread messages on it. "The hospital's test report is out."

Jian Jing was shocked: "What is it?"

"Mold." He said, "Do you want to go to the technical department with me?"

If you are too attentive, you are either a thief or a thief. Jian Jing was skeptical: "Why are you taking me with you?" "

Of course you have a lot of face." Ji Feng said, "We only have two days, half of it has already passed, we have to seize the time."

Jian Jing snorted: "Do I have a lot of face?"

"Of course, I'm a famous writer." Ji Feng pulled up the reluctant writer, "Don't you want to visit the next department?" Jian

Jing reluctantly said: "Okay."

Ji Feng did not lie. As soon as he arrived at the Criminal Technology Department, he was immediately given the cold shoulder by his colleagues.

"You're here again?"

"I haven't done it yet."

"Go away."

God is angry and people are resentful.

But when everyone saw Jian Jing following him, they suddenly became much friendlier.

"Is this Teacher Jian?"

"I've heard of your name before."

"Welcome, welcome, my child is your fan, can I get an autograph?"

Taking this opportunity, Ji Feng took down the physical evidence of the June 15 case from the shelf, flipped through it, and found no obvious traces of mold.

He thought for a moment and said, "Teacher Jian, please sit for a while, I'll go get something."

Jian Jing looked down on Ji: "Selling friends for glory."

"What glory? I'm asking for clues."

He came and went in a hurry, and soon found the clothes that Tan Hao had changed in the place where he was detained. At that time, he was arrested in a bathrobe, and the clothes were still in the police station.

"Please help check this, it's urgent." Ji Feng lobbied everywhere.

Colleagues looked indifferent: "Which work is not urgent?"

"Please be kind to me for bringing a great writer with me." He tried his best to persuade them, and finally got their consent.

An older sister pushed her glasses and said meaningfully: "Remember to invite me to the wedding."

Jian Jing: "???"

Ji Feng remained calm: "My family's Yunyun's graduation banquet, I will definitely invite you."

"Get lost."

Ji Feng fled the scene.

Jian Jing was too lazy to argue with him, so she got in the car and gave orders: "Go to the crime scene."

"Think it through first?"

"Then I'll tell you my thoughts from beginning to end." Jian Jing organized her thoughts, "First of all, you have ruled out places like the ceiling, outside the window, and the ventilation duct. I think that using a machine to kill people or create a secret room is no longer realistic."

"Next, I will consider the simplest scenario. The deceased locked the door for some reason and accidentally created a secret room. But this doesn't fit the plan to frame Tan Hao. The other party must have planned it in advance to cause him to be unconscious and just woke up.

"Besides, there are two people who discovered the crime this time, and the deceased suffered a fatal injury on the back of the head. This ruled out the possibility that the deceased was still alive when they entered the room, and that another person killed him while someone called the police and left. Moreover, Tan Hao was in the room at the time, which meant that three people could testify against each other.

"In this case, the last possibility left, although the probability is very small and incredible, may be the real answer."

Jian Jing looked at him and raised her eyebrows: "Test you, what is the most earthy answer?"

"The murderer is in the room?" Ji Feng had guessed her thoughts before and immediately pointed out the doubts, "But since he planned to frame Tan Hao, it doesn't make sense for him to choose such an outrageous method at the most critical place-wait."

Jian Jing's tone rose slightly, and he said happily: "Yes, this was not the original plan. The person in charge went to call the deceased because of the arrival of a big customer. It was originally an accidental event."

"The murderer may have had two plans: First, she took on the role of the person in charge and played the role of the first person to discover the door but got no response. In this way, whether the door could be opened was entirely up to her, and the fake secret room could become a real secret room. Second, she calculated the time when Tan Hao woke up and let him open the door from the inside. He is the biggest suspect, and even if he said that the door was not locked when he opened it, the probability of being believed is very low."

Ji Feng said: "But the arrival of the person in charge ruined her plan."

"Yes, at 11 o'clock, she was still at the crime scene, but the person in charge suddenly came to knock on the door. In a hurry, she locked the door and played the recording to create the illusion that the deceased was still alive. However, although the person in charge left, she knew that he would be back soon and she could not leave.

"At this time, she could only take the risk to stay and create a chance for herself to escape. Do you remember that I sat on the sofa for a while that day, and then I found that the position of the sofa was wrong and it had been moved.

"The murderer deliberately moved the position of the sofa, so that when people coming in from outside see the deceased, their first reaction must be to go over and check. The sofa was lying there, and there was a coffee table on the other side, so he could only turn his back to the door."

After analyzing this, we have arrived at the scene.

The crime scene remained the same. The person in charge wanted to find out something, but was stopped by Ji Feng.

The two stood at the door of the luxury suite and tried to reconstruct the scene at that time.

Ji Feng stood next to the body and turned his head to look back. Because of the screen at the entrance, he could not see the movement at the door clearly. But he said, "There were two people coming in."

"There is something wrong with the security captain." Jian Jing walked back and forth, and the thin heels of her sandals made crisp footsteps on the smooth marble. "If she doesn't want to be seen by the person who discovered the deceased, she can only hide behind the curtain here."

The curtains of the suite are expensive velvet, covering the entire right wall of the living room. The material is thick and heavy. If you hide behind it without looking carefully, it is difficult to find it for a while.

She said, "Tan Hao just woke up from shock and was not in a clear state of mind. It's normal that he didn't notice anything. But there is a high probability that the security captain saw her coming out from behind the curtain."

"He must have lied. If he hadn't covered her up, she would have been the third person to find the body." Ji Feng confirmed her guess.

The distance from the curtain to the door was nearly ten meters. It was too risky to escape. Pretending to hear any movement and come out was undoubtedly a better cover. But the murderer did not become the third person. Instead, he was not notified until after the incident. This means that when she evacuated, the security guard did not hear any movement at all.

The feasibility is too low.

"Now it's a choice between two." Jian Jing said so, and she already had a preference in her heart.

The secretary and Manager Min both said that they only learned about the accident of the deceased after being notified by the person in charge, which was after 11:12. The treasurer came back at 11:15, the last one on the timeline.

In addition, according to the original plan of the murderer, she needed to pay attention to the situation in the house at all times in order to deal with it, and the actions of the treasurer did not meet the requirements.

The secretary and Manager Min, who had been staying in the lounge and the office, both met the conditions.

Considering Manager Min's action of diverting trouble, the latter is more suspicious.

The question is, "Where is the evidence?" Ji Feng asked, "What about the motive?"

Jian Jing thought for a while and said, "The security guard's confession is the key, we have to get the truth from him."
