i must be in hell

"The angle between the floor-to-ceiling windows on both sides is [-] degrees, the floor height is [-] meters, and the space is [-] square meters."

"The floor-to-ceiling windows can be opened and have guardrails."

After Yuan Fei left, the criminal police thoroughly investigated the office.From the spatial structure to every part of the interior, nothing is missing.

Ning Xiao looked around the office, and finally his eyes fell on the place where the deceased fell.The railing at that place had been damaged, and it was for this reason that the body of the deceased lost its ability to prevent him from falling from a high altitude.

Xu Shangyu was squatting on the ground, carefully observing the broken part of the railing.

"For the time being, there are no traces of man-made damage, and it looks like natural wear and tear. According to the posture in which the deceased fell, he should have leaned against the railing at that time. After the railing was damaged, he fell backwards and turned head down in mid-air. position, it will be fatal immediately."

"No." Ning Xiao denied: "If it is a normal backward leaning, at the height of the fifth floor, the head and cervical spine should touch the ground together when falling to the ground. But judging from the situation at the scene, the deceased is more The head landed on the ground. From this, it can be inferred that at the moment of the fall, the forward leaning force of his upper body was relatively strong."

"Center of gravity leaning forward?" Lu Fei asked aside: "Is that so?"

He stretched out his hand and made a gesture of reaching out.

"Isn't this half of the body leaning out of the window?" Lu Fei said: "No one would do this if they have nothing to do. Is it really suicide?"

Ning Xiao didn't answer, he took a few steps forward and stood where Zhou Yang fell.The height of the fifth floor, including the steps and the height of the hall on the first floor, is tens of meters away from the ground.Standing in this position, the cold wind blows in your face, and you can't help but feel dizzy when looking downstairs.Ning Xiao was a little afraid of heights, so he shook involuntarily, and Xu Shangyu who was beside him immediately gave him a hand.

"I'm fine." Ning Xiao waved his hand, and tried to lean forward and lean out the open window.

On the sidewalk tens of meters away, the red blood on the ground has not yet dried.Zhou Yang's body was covered with a white cloth and put aside, the smell of blood still seemed to linger in his nose.Standing at the position where a person's life was just taken away, Ning Xiao closed his eyes and tried to stick out his entire upper body.It wobbled, and in the next second, it seemed that it was about to fall from the sky.

A hand stretched out and held him tightly.

"What are you doing?" Xu Shangyu asked, and quickly pulled Ning Xiao out of the danger zone.

The two of them fell backward together, hitting the desk behind them hard.Xu Shangyu, who was cushioned behind Ning Xiao, let out a muffled snort, and slammed his back against the edge of the table with great force.

"team leader!"

"Ning Xiao!"

Lu Fei and Zhao Yun exclaimed.

"It's okay." Xu Shangyu pulled the man over and propped up his body with one hand.His back slammed against the corner of the table, and he gritted his teeth while staring at Ning Xiao.

"Is it fun? You almost fell off just now, do you know that!"

Being reprimanded, Ning Xiao didn't make a sound for a long while, but stared at the point where Zhou Yang fell, wondering what he was thinking.

"Xu Shangyu." After a long time, he said softly: "You know, today is sunny."

Xu Shangyu was taken aback.

"The weather is fine and the sun is abundant." Ning Xiao continued, "The light is very strong. The moment I stood here and leaned out, I closed my eyes."

"What does this mean?"

He stood up and looked at everyone with black eyes. "This shows that Zhou Yang didn't commit suicide at all."

The sun was so harsh that people couldn't help but close their eyes when standing in front of the window. The height of the fifth floor was unobstructed, facing the east directly, and the sunlight was very strong.At the moment of jumping, anyone will subconsciously close their eyes tightly.But Zhou Yang's eyes were wide open, and when he landed, his eyeballs were squeezed out due to excessive squeezing.

This shows that at the moment of the fall, he was caught off guard, and there was no time to close his eyes in a hurry.

He was totally unprepared for this fall, so there was absolutely no possibility of suicide!

Following Ning Xiao's words, the room fell silent instantly.Lu Fei couldn't help swallowing, and said hoarsely: "But Zhou Yang's secretary said that no one had been in this room before we came in. Zhou Yang was alone in the room all the time. If it wasn't suicide, what would it be. "

Zhao Yun asked: "Is it possible that it was purely an accident?"

Accident?Ning Xiao subconsciously denied this possibility.How could it be such a coincidence that someone accidentally fell when he and Zhang Weiwei were out, and it happened to fall in front of them.He had long been certain in his heart that this was definitely not an accident, but another move made by Heye.But suffering from no evidence, Ning Xiao could only hold back these words in his heart.After proving that it was not a suicide, how to prove that it was not an accident, but a murder in a secret room?

Yes, chamber murder.

At that time, Zhou Yang's office was locked from inside the house, and the only open window was still on the fifth floor.No second person can come in, and there is no trace of the second person ever going in or out.If this proves that this was not an accident, there is only one possibility - murder in a locked room.

For any detective, a locked room case is the most challenging and most arousing case.Even if he is just an ordinary reasoning writer, Ning Xiao has to admit that he has an extraordinary obsession with this secret room case.

However, if you are too attached to one thing, you will often ignore other aspects.Ning Xiao, who was concentrating on this case, probably wouldn't be able to notice He Ye's other actions.

This is probably already in He Ye's calculations.Even though he knew it was a bait, Ning Xiao couldn't help stepping on it.It's like teasing a cat with dog's tail grass. Even if the cat knows that this is a bad taste of human beings, it can't help stretching out its paws to scratch.That itchy feeling is really too difficult to control.

After this case, He Ye must have other actions.And the only way at present is to solve the case as soon as possible and pay attention to Heye's every move.

Don't worry, don't be impatient.

Ning Xiao took a deep breath and reminded himself in his heart.Pay attention to every detail, often the truth of the case is hidden in an inconspicuous detail.What is hidden here, what is there?

He opened his eyes wide, scanning every corner of the room with an X-ray-like vision.Desk, decoration, bonsai, bookshelf, office desk, bonsai, bookshelf…

Ning Xiao suddenly stopped scanning, his gaze stayed in a certain corner, motionless.He looked at the bookshelf less than a step away from where Zhou Yang fell, and looked at it quietly for a while.

I always feel that there is something wrong with this bookshelf.There were only a few books on the bookshelf, while other places in Zhou Yang's office were filled with simple decorations.But this bookshelf is so empty that it feels awkward.

"Lu Fei!"

Ning Xiao suddenly yelled. "Bring me a chair!"

"Yes, yes!" Lu Fei was taken aback by his excitement, but he still moved a chair to Ning Xiao's side.

Ning Xiao climbed onto the chair and could just see the top of the two-meter-high bookshelf.Because the top has not been cleaned for a long time, a layer of dust has accumulated.But near the edge, there is a clear difference between the dust.In the middle, leave a shallow circle.It was a trace of what was once placed and then removed.Ning Xiao's eyes lit up, and he looked at the bookshelf below the top.He gently moved a few books away, and sure enough, he found a clearer trace on the bottom plate of this bookshelf, the exact same prototype.

found it!

Ning Xiao was a little excited, turned around and wanted to share his discovery with others.But the moment he turned his head, he was blinded by the strong light coming from the floor-to-ceiling windows to the east.When he turned his head away involuntarily, when he opened his eyes again, he saw the small church across the street.

The cross on the top of the church shone dazzlingly in the midday sun, but some parts seemed to be covered, leaving a faint blackness.

Lu Fei and Zhao Yun stood below, watching Ning Xiao touch this for a while and touch that for no reason, and seemed to be dancing.If they didn't know the details of Ning Xiao, they would really think that he was a patient who escaped from the mental hospital.

Meanwhile, Xu Shangyu focused on observing the damaged railing, carefully paying attention to every detail of the railing.He reached out to explore the shelf supporting the bottom of the railing, and then inspected the broken bracket.In a daze, he seemed to have discovered something.

Xu Shangyu immediately looked up and looked for Ning Xiao.At the same time, Ning Xiao also jumped off the chair and looked at him.

"I found it!"

The two said almost in unison, Ning Xiao was taken aback for a moment, and then smiled.

"It seems that we have all discovered the clues left by the murderer, Officer Xu."

"What, what's going on?" Lu Fei and Zhao Yun were puzzled and asked, "What did you find? What are you looking for?"

Ning Xiao looked back at them and said:

"What we're looking for is a cat that took a human life."

……

"Hey, Zhang Weiwei, slow down!" Seeing the child running ahead, Yu Meng was panting after chasing after him. "Don't run! You haven't gone to the hospital for an examination, don't exercise vigorously!"

Yu Meng didn't think that the child would be so lively when he woke up, and his feet would be so lively that he would not even be able to catch up with him.

"I'm not sick! I'm fine!" Zhang Weiwei gritted his teeth while running in front.

Uncle Xu clearly asked him to protect Ning Xiao, but when things came to an end, he was not only fainted by fright, but also asked Ning Xiao to protect him instead.After knowing how she was fainted by fright, Zhang Weiwei kept holding back her breath.

Be good to the black cat. If he hadn't looked at the cat in a daze, he wouldn't have been almost hit by the corpse that fell from the sky.Isn't it just a corpse, Zhang Weiwei gritted his teeth and thought, my parents are both corpses, I'm afraid that you, a stranger's corpse, won't make it!I definitely didn't faint when I saw the corpse. I must have seen the black cat bewitched!

He thought angrily in his heart that he was going to come to this church to settle accounts with that black cat.

It was strange to say that after seeing it so many times, he couldn't remember the appearance of that black cat.Maybe it was too far away, maybe it was the memory confusion after being frightened, now he only remembers a hazy black shadow, and can't remember the appearance of the cat at all.What is going on, he must come to ask clearly!

Thinking of this, the little boy ran away without warning, leaving Yu Meng behind.

Just when Meng was still crossing the road across the street, Zhang Weiwei had already run to the door of the church.There is a small courtyard in front of the church, the gate is closed, and no one seems to be in it.Panting for breath, he stepped forward and knocked hard on the door.

Bang bang bang!

"Is anyone there! Is anyone there?" After several knocks, no one responded, just when he was about to give up in discouragement.

With a creak, the courtyard door was opened from the inside.

A figure landed on Zhang Weiwei's face, the child was startled, then swallowed and asked, "Uncle, I want to ask if you have a black cat here."

"Black cat?"

The man in priestly attire looked at him with a smile and repeated his words.It was clearly noon, but there seemed to be a chill on this person, which made Zhang Weiwei shiver involuntarily.

"Unfortunately, no."

The man's voice came in a low voice, like a stream beating on a pebble, which made people feel chilled.

"Although I've always wanted to have a cat, they never seemed to like me."

He chuckled: "This one too."
