Just then, they suddenly heard an exclamation from the front end of the plane.

"Dead!" Such exclamations were heard.

"Stop, stop," Chiha's reaction was quick, and he immediately grabbed the hand that was hammering the ribs of the gray plain and the hand that was pinching the back of the neck at the same time, and gently stopped it. "Something seems to have happened up front."

……

When Chiba and Ash Yuan ran to the front of the plane, they saw the scene of crying and laughing - the corpse of the Makki was lying on the ground, and the next Shindo Tsu was desperately trying to prevent the passengers from approaching the Makki to check on her condition.

"Listen to me!" Shintang-chan explained. "She's been poisoned on the plane, but she didn't make it public so as not to frighten you, you can ask the purser!"

"She's right!" Finally, the purser, who slipped off the plane, ran over and said this. "Hurry up and evacuate! The nose may have caught fire, so please get out of here with me! ”

……

"The difference in arteriovenous oxygen levels is 2.7 percent," the doctor at New Chitose Airport said to the purser who was waiting for the examination reports from the two captains after completing the examination. "Combined with what you reported, we suspect cyanide poisoning."

Poor arteriovenous oxygen content means the difference between the oxygen content of arteries and veins, under normal circumstances, this data should be about 4% (arterial 16% venous 12%), and this number is as small as only 2.7%, which generally means that the patient's tissues are unable to draw nutrients from the arterial blood, which is the typical symptom of cyanide poisoning.

So, does the cyanide poisoning of the two captains have anything to do with the death of cyanide poisoning in the bush?

"Well, can I ask?" The purser finally hesitated a little and asked. "If it's the back of your own hands, is it possible to be poisoned?" (That's what the doctor on the plane reminded us of, and the purser now finally realizes what he's suspicious.) ）

"Behind your own hands?" The doctor was stunned for a moment before replying. "Unless there's poison on the back of your hand, it's unlikely."

"The back of the hand," the purser looked at one of his hands. "In other words, as long as the hand is poisoned, it is possible to poison the person who kissed the back of the hand?"

"Possibly," the doctor nodded. "You...... Do you know what? ”

"......" The purser hesitated, then nodded. It's possible. ”

……

After about twenty minutes, the police had arrived and began to take notes on everyone present. But at this moment......

"Mr. Policeman," said the doctor on the plane just after completing the transcript. "I want you to hear what I think about this case — I mean my thoughts on the method of murder."

"What do you mean?" The policeman who recorded the transcript was stunned and looked at him suspiciously. "Do you have any opinions?"

"We've checked, and both captains are showing mild symptoms of cyanide poisoning, and Miss Makiki happened to die of cyanide poisoning - it's obviously related, isn't it?"

"Do you know what's going on?" The policeman frowned.

"The purser said she had seen the two captains kissing the back of Miss Makishuri's hand – if there was cyanide on the back of the hand, that would explain the situation."

"And then?" The policeman immediately asked. "Did you find any signs?"

"We've found cyanide, in many places," the doctor said, glancing at the purser, who had already approached him. "The purser and the doctor here can also testify."

"Both captains have residual cyanide on their lips, and Miss Mushu has the tip of her tongue, lips, and nose, and the content of cyanide on her nose is very large." The purser nodded. "So we hope that you will immediately search for Natsuki Sakai, who is putting on her makeup, and search her foundation before she can destroy her evidence."

……

"Didn't I already say that? I don't know! Natsuki Sakai retorted with a frown. I had no idea what was going on! And don't you think you should ask Miss Agent instead of me? ”

"We have plenty of manpower, so we can ask questions one by one," the policeman said, holding a pen and unhurried. "And this is a homicide after all, so we definitely have to be as cautious as possible."

At the same time, outside.

"Haven't you found it yet?" Gray Yuan Ai stood around the corner, looking at the airport transcript room not far away.

"No," Chiba frowned deftly as she flipped through Natsuki Sakai's package. "I've seen other makeup, but I just can't find the foundation – could it be on her?"

"Impossible, there's no space," Gray Plains denied. "There's no way she's going to hide her foundation in that way."

"If she throws it away, it's going to be a big problem," Chiba sighed. "In that case, the garbage has already been cleaned up, and it's a big headache to think about."

"What are you doing?" At this moment, Conan's voice suddenly came, and he came over with an envelope in his hand.

"Uh......" Chiha, who was rummaging through Natsuki Sakai's bag, was a little embarrassed. We're ......"

"Are you looking for Natsuki Sakai's foundation?" Conan shattered the thoughts of Thousand Feathers and Gray Plains in one sentence. "Isn't that right?"

"Ah......" Chiba nodded curtly. Yes......"

"It's okay," Conan shook the envelope in his hand with a smug look that he couldn't hide at all. "Still, it looks like I'm one step ahead, I've found it."

"It'...... this," Qian Yu looked at the bulging envelope. This is the foundation – the cream? ”

"yes," Conan nodded, pressing the envelope to highlight the outline of the cream foundation's box. "I did the same thing as you before, and then I found that there was nothing, so I initially deduced that Natsuki Sakai might have thrown away the foundation, so I called up the surveillance video to see her whereabouts, and then I guessed that although Natsuki Sakai didn't throw anything, she once went to the sending point during the process of going to the toilet alone, so I guessed that she might have sent the foundation somewhere, so I went to the post center and tried to get the letter back."

With that, Conan walked past Gray Plains and Thousand Feathers. "Let's go, then we just need to wait for Natsuki Sakai and the others to finish taking notes, and then hand this over to the police. I believe that enough cyanide should be detected in it to convict Natsuki Sakai. I'm quite curious.,If the reason for Yaguchi Masayo to kill someone was to prevent Makiki from jumping ship,What was her reason for killing Makiki? ”
