The death of the male host, Ikemura Xun, set off a storm in Ikemura's house.

Ikemura's father, Toshimitsu Ikemura, his son Takazen Ikemura, and his future daughter-in-law, Sachiko Katsuragi, all hurried over when they heard the news, and together with Mrs. Ikemura Gongjiang, who had just come out of the study, blocked the door of the study.

"How could my dad/son die?!"

The families are not emotionally stable.

Seeing this posture, they all wanted to rush into the door and hold the body of the deceased to stage a father's love and filial piety.

Fortunately, Kogoro Mori showed his professionalism as a police officer.

He reluctantly blocked the door of the study and helped his daughter protect the scene:

"Don't get excited! Do not enter the crime scene. ”

"Trust me... My daughter is a police officer in the forensic section, and she will help everyone find out the truth! ”

"A police officer from the forensic section?"

Mrs. Ikemura's expression suddenly became a little subtle:

Because of Lin Xinyi's relationship with the management officer, the once inconspicuous soy sauce department of the identification class is now in the limelight.

She looked carefully at Maolilan's young and immature face, and the blue school uniform she hadn't had time to change out of after school, so she couldn't help asking:

"Isn't this kid still a high school student? How can he be a police officer in the forensic division? ”

"Haha..."Mori Kogoro's tone was a little smug.

Speaking of his daughter's achievements, he seems to be happier than talking about himself:

"My daughter Xiaolan is the famous 'beautiful girl forensic doctor' in the newspaper recently!"

"Lin Xinyi knows, right? That guy just saw that my daughter inherited my extraordinary reasoning ability, so he begged Xiaolan to be his student! ”

"This..."Mrs. Ikemura's face suddenly changed: "This Miss Maori is the personal disciple of the forest manager?" ”

There was an irrepressible shock in her voice.

Ikemura Takazen, Sachiko Katsuragi and others on the side also looked surprised, as if they had seen some big star.

"Hey, hey... That's an exaggerated reaction, isn't it? ”

Mr. Heiji Hattori, who is accustomed to enjoying the spotlight and cheers, but is now being snubbed by the audience, can't help but be a little surprised:

"A little girl who has just debuted has more treatment than me, it seems that my fame in Kanto is really not big enough!"

"But that's fine..."

"The more famous the opponent is, the more valuable it is to challenge."

Hattori Heiji was blocked from the scene, but his eyes were still full of fighting spirit:

"Miss Maori, even if you keep me out of the scene, I won't be defeated easily."

"Just the clues I just saw are enough for me to solve this mystery of murder in the secret room!"

His eyes were full of confidence.

Of course, it is not a good feeling to be forcibly asked out of the scene.

But this is like a waste stream of divorce, the worse he is suppressed by his opponent in the early stage, and the more he defeats his opponent in the later stage, the more pleasant the slap in the face will be.

Therefore, Hattori Heiji is holding back his strength fiercely at the moment, wanting to find out the truth before Mao Lilan.

"To achieve the secret room technique I deduced, you have to use a fishing line."

"And the deceased died in the last half hour, and most of the murderers have not had time to dispose of the tools used in the killing."

"So, just let me find this line..."

"I can prove my conjecture!"

"And the murderer, most likely, is the man!"

Hattori Heiji thought so, and his eyes became more and more determined.

He quietly left the scene and walked downstairs alone, to the place where the evidence was most likely hidden in his reasoning.

And noticing his departure, Conan couldn't help but be a little concerned in his heart:

"Looks like the guy called Hattori has picked up some clues."

"Although this guy's previous reasoning was a bit crotch-pulling, since he can be called 'Kansai's Hattori', I'm afraid he also has some strength."

"Xiaolan, she... Can you really win? ”

Maorilan herself had no interest in this so-called showdown, but Conan helped her get in a hurry.

However, as a member of the idle people at this moment, Conan can't help at all.

The only thing he could do was to cast his gaze hidden in the door and on Xiaolan.

At this time, Maolilan was already busy with the autopsy.

She moved the body of Isao Ikemura to the ground and placed it on the open ground.

This location is also relatively close to the door, so that the people waiting outside the door can clearly see the details on the corpse.

The medical examiner is required to take photographs at any time during the autopsy so that evidence can be left behind and certain signs of the corpse that may only be kept for a while.

And Maolilan doesn't have a camera now, and he is here alone, lacking a helper to help take pictures and record.

She simply asked Kogoro and the others who were waiting outside the door to be a witness, and let them watch her autopsy.

Everything is ready to go.

Maolilan straightened up her long hair that was a little in the way, put on a mask and gloves, but her eyes were still a little hesitant:

"Do you want to do a postmortem examination now..."

"Or... Wait a little longer, wait for Mr. Lin and them to come over? ”

As a new apprentice, although Mao Lilan has learned a lot of knowledge with talent and hard work, he is a half-baked person who has not been systematically studied after all.

Some traces that tend to be empirical, she learned and practiced at the same time, but she mastered them quickly.

But the post-mortem is a professional work that requires a certain medical foundation, and she really hasn't done it alone.

At this moment, without the guidance of Lin Shinichi and Asai Chengshi, two professional teachers, Mao Lilan couldn't help but feel a little weak.

"No... No time can be wasted. ”

"Mr. Lin said that the sooner the autopsy should be done, the better."

"It doesn't matter if my level is insufficient, when Mr. Lin comes, let him help check and fill in the gaps."

After some hesitation, Maolilan finally mustered up confidence.

Her gaze gradually became determined, and her movements became fluid and neat.

According to Lin Xinyijiao's corpse examination process, the first thing she determined was the overall condition of the corpse surface such as corpse stiffness and corpse spots.

And the preliminary examination results are the same as what the Hattori detective just said:

"The muscles are relaxed, there are no corpse zombie spots, and there is still residual warmth on the exposed face, hands and feet."

"The time of death will not exceed half an hour at most."

Judging the time of death is also a basic craft for detectives.

Heiji Hattori didn't make any mistakes in this regard.

Merely...

"There is a pinhole in the neck."

According to the standard process of inspecting from head to toe, Moriran quickly discovered what Hattori Heiji had just discovered.

But there are some things that Mr. Detective can't notice, but Mao Lilan, a half-baked forensic doctor, can notice:

"The location of this pinhole... Approximately two transverse fingers to the left of the thyroid cartilage. ”

"This location is very close to the carotid artery, maybe the poison needle is directly inserted into the carotid artery."

"If poison is injected from such a place..."

"The drug will enter the brain through the arterial blood circulation at the fastest speed, and then spread throughout the body."

Mao Lilan's expression suddenly became a little solemn.

She couldn't help but think of the pharmacokinetic knowledge that the "detective" Miss Shiho Miyano had popularized when she was solving the puffer fish poison needle murder case in the Japanese restaurant that day.

Administered from the arteries of the neck, the effect of the drug is the fastest and most rapid.

If tetrodotoxin, a powerful nerve agent, is used, it can make the deceased neuromuscular paralyzed and fall into suspended animation almost the moment the poison needle pierces the deceased's neck, and suffocates to death in a short time.

"Wait..."

Maoliran's cheeks suddenly turned extremely pale.

It was as if she had discovered some unacceptable cruel truth, so much so that she couldn't even hold back her body and trembled slightly.

"What's wrong, Sister Xiaolan?"

Conan, who had been watching from the sidelines, couldn't help but ask with some concern.

Maolilan's face turned pale, and he replied in a trembling voice:

"Mr. Ikemura's lips and fingertips are just starting to turn purple."

"Huh?" Everyone was slightly stunned:

"yes... So, what's wrong with that? ”

They all saw the change in the corpse that Maoriran was talking about, but they didn't understand what she was trying to say.

Even the great detective Conan didn't react for a while:

The lips and fingertips are bluish-purple and medically known as "cyanosis".

The red color of the blood is due to the presence of hemoglobin inside the red blood cells. When hemoglobin is sufficiently combined with oxygen to become oxyhemoglobin, its color is bright red; When it releases oxygen, which becomes deoxyhemoglobin, the color changes to a dark red.

When a person falls into a state of suffocation, the oxygen saturation in the blood decreases and the deoxyhemoglobin increases, and the "cyanosis" phenomenon of bluish and purple changes will appear in the parts with thinner skin, less pigment and richer capillaries.

Therefore, cyanosis of the lips and fingertips is a typical sign of death by asphyxiation.

This sign occurs in deaths from poisoning caused by many poisons that affect respiratory function.

Now that it has been determined that Ikemura died of poisoning, it seems that there is nothing strange about the discovery that he has signs of suffocation.

So, why is Xiaolan so shocked?

Conan was puzzled, but Maorilan suddenly came back to his senses.

She hurriedly reached out and pressed the deceased's dilated pupils, and found that the dilated pupils did not return to their original shape.

"It's over... It's too late. ”

"Mr. Isao Ikemura, he's really dead."

Maolilan's big eyes were full of pain and self-blame.

"Xiao, Xiaolan?" Looking at his daughter's pitiful appearance that almost collapsed, Maori Kogoro finally couldn't hold back and shouted: "What the hell is going on?" ”

Maolilan bit her lip tightly and said to herself:

"Cyanosis of the lips and fingers is usually in the middle of the asphyxia process, and the 'inspiratory dyspnea' that the person is not dead will begin to appear."

"And the color of the skin and mucous membranes changes with the color of the blood flow."

"But the lips and fingertips of the deceased have just become cyanosis..."

"In other words, when I started the autopsy just now, the blood in his body was still flowing."

"W-What?!"

Everyone was shocked, including Maori Kogoro, who is Xiaolan's father:

"Well, that's not saying... Mr. Ikemura, was he still alive just now? ”

"That's right... He was alive just now. ”

"It's just that the effect of the drug is too fast, and his nerves and muscles are instantly disabled, so he falls into a state of suspended animation."

"And now under the suffocation caused by the disability of the respiratory muscles, Mr. Ikemura is really dead."

There was pain in Maolilan's voice, and there were even tears rolling in his eyes.

She turned her head and looked at Mrs. Ikemura, who had changed face in the crowd, with this tearful gaze:

"Mrs. Ikemura, why did you kill your own husband?!"
