Diane completed her task successfully and could not wait to find Jian Jing to report.

The little princess was preparing to have a snack.

On a long international flight, there was more than one meal.

The flight attendants thanked her for standing up and the richness of the meal exceeded the original quota, including lovely cakes, hot coffee, and various flavors of nut ice cream.

The two discussed the case while eating.

Diane opened her notebook and reported briefly like every time the company held a general meeting: "I have asked the deceased's secretary, translator and the Bao family's nanny, and got the following information..."

Jian Jing choked and said quickly: "Relax, no need to read the report." She complained about Kang Mucheng again, "Boss Kang and I are different. I don't like to omit information."

Kang Mucheng, who was standing next to her, heard it and glanced at her: "What?"

"No problem." She turned her head, "Take your time, come, eat a cookie first."

Diane ate a chocolate cookie and drank a few sips of juice, and her thoughts became clear: "I chatted with the secretary for a while first. She didn't want to say much at first, and talked about this and that with me. Later, she was willing to tell me a few truths."

As a secretary, you must be careful with your mouth. If you reveal your boss's affairs everywhere, do you still want to work in the company? But on the other hand, there is a wall between the boss and the employees, but the employees have more things in common.

Complaining about overtime, complaining about the boss, complaining about the boss's mistress...you can immediately resonate.

Diane talked about how she had to read and understand things when taking a long-distance flight, and slowly lowered the other party's defense. Then she pretended to reveal a secret, saying that the matter was very troublesome and it would be better to solve the case as soon as possible to avoid everyone being in trouble.

After fooling around for a long time, she finally got to the point.

According to the secretary, last night, President Che participated in a drinking party, and it seemed that he wanted to attract new investment, dilute President Meng's shares in the company, and weaken his voice. At

ten o'clock this morning, President Che came to the company for a meeting. He had a cold and asked the secretary to buy medicine. After lunch, he took cold medicine and the symptoms seemed to be relieved a lot.

But while waiting for the flight, the air conditioning in the lounge was turned on high, and the cold symptoms worsened again. To prevent the infection from spreading to the child, they specially changed their positions.

Jian Jing made a pause gesture: "Did the deceased come to the company today?"

Diane was very sensitive to the schedule because of her job, and said: "Yes, he arrived at the company at 10 am, and held the regular meeting as usual, had lunch at 12 pm, and left for the airport at 1:30 pm."

Jian Jing said: "Did President Meng and President Bao go to the meeting?"

"Yes, but I heard that President Meng knew that President Che had a social event last night, and he was very unhappy. He left in the middle of the meeting, which was not a good thing. The people below are worried whether the two shareholders will break up."

"Then what?"

"The deceased went directly to the airport to meet up with his family. Mr. Bao went home first to pick up his wife and daughter, and arrived a little later than him. Mr. Meng came directly here after leaving the company."

Diane looked at the records and reported the time accurately: "Mr. Meng arrived at the airport at about 13:30, Mrs. Che and the children were around 13:45, the deceased's time was the most accurate, 14:05, and Mr. Bao and his family were the latest, 14:15."

Jian Jing couldn't help but praise: "You secretaries are all very capable."

Diane smiled modestly: "It's just my job. There are chat records on WeChat, so I don't need to remember them specifically."

"This is very important." Jian Jing nodded, and asked, "Where are the nanny and the translator?"

Diane: "The nanny said a lot of gossip about Mrs. Bao."

Jian Jing was very interested: "What did she say?"

"She said Mrs. Bao is a vixen who flirts with men all day long and rarely takes care of the children. She has never seen a mother like her." Diane lowered her voice, "She also said that Mr. Bao is most likely cheating on her husband."

Jian Jing: "How did she know?"

"I asked that, too." Diane said, "The nanny said that after the birth of the child, Mr. Bao was a little dissatisfied with his wife, and was hot and cold, but in the past six months he has become particularly enthusiastic."

She counted on her fingers: "Mrs. Bao liked a skirt that was out of print in China, so when he was on a business trip, he went to several second-hand stores and finally bought it; she liked that Japanese dumpling, I guess it was wagashi, and on her birthday she flew to Japan and bought several boxes; this afternoon, they could have come by themselves, but Mr. Bao went home to pick them up, and took care of the children himself along the way, and never complained about his wife again..."

Jian Jing: "...tsk."

"A man who suddenly becomes attentive must be guilty. Why else would he be guilty? He must have cheated on her." Diane said the nanny's conclusion, and she was also impressed, "No wonder Mrs. Bao knew about it."

Jian Jing was so happy that she quickly ate two bites of cake to suppress her sadness.

"Where's the translator?" She handed Diane a sandwich and urged her to continue, "Did he say anything?"

"He is from a travel agency and is not familiar with the three families. But he was the first to arrive at the airport, at 13:00." Diane said softly, "When I asked him, he was a little hesitant, as if he knew something, but didn't dare to say it. After a long time, he stammered and said that he seemed to hear someone making a phone call." Jian

Jing: "Mr. Meng?"

"Probably. He said it was around half past one." Diane's face became increasingly solemn. "He said that the man had a very bad tone when he called, and his words were not right. He said things like 'He dares to mess with me, I'll make him pay' and 'He thinks he's so great, but we can't live without him' and so on."

Jian Jing nodded: "Then it should be President Meng. He must be very angry when he knows what the deceased did last night."

Diane asked cautiously: "That's very strange. If he was so angry, why did he go to the airport? Unless he had a reason to go - but they were going on vacation."

"You make sense." Jian Jing fell into deep thought.

Diane hesitated to speak: "Um, Teacher Jian..."

"Hmm?"

"The milk was poured after 7 p.m., why didn't you check who went to the toilet after the meals were distributed?" Diane wondered, "Wouldn't we be able to identify the suspect quickly this way?"

Jian Jing asked, "Have you seen "Mystery in the Clouds"? "

Diane smiled embarrassedly, "I've only watched the drama."

"Same, the murder method discovered is not necessarily the real murder method." Jian Jing said, "The duration of cyanide poisoning is difficult to determine. It can be as short as 2-3 minutes and cause death, or 10-30 minutes, and even longer can be several hours."

Diane choked.

"Unless we can find the real murder weapon, there is little point in checking the timeline." Jian Jing sighed, "The current situation is that anyone can kill people, regardless of whether they left their seat or not."

Diane pondered: "What should I do?"

Jian Jing put down the dessert spoon, leaned back in the reclined seat, and thought: "If the cause of death was the glass of milk, everything would be simple. But this does not explain why they chose to poison on the plane."

The plane is a special closed environment, which can be said to be more closed than the closed room on the ground.

If the police poison on the plane, they can immediately lock the suspect range, and it is not convenient to destroy the evidence. Even if they have to do this (for example, only at this time can they get close to the deceased), they should choose a poison that takes effect more slowly so that they can dispose of the evidence after getting off the plane.

But if it is not milk, why bother?

"Well, it seems that we still need to ask a second round of questions." Jian Jing stretched her back and got up to work. "Let's go Diane, let's ask them a few more small questions. If we are lucky, the truth will be in front of us."

Diane: Really? I don't believe it.

She didn't see the light at all.

But no matter when and where, it is no good to go against the boss. She followed obediently, ready to take a good look at what the little princess was going to do.

Jian Jing called the deceased and his group and three flight attendants, and began a public interrogation on the cabin.

"Everyone should know that Mr. Che Maocai died on the plane." Jian Jing skipped the meaningless greetings and went straight to the point, "And I have reason to suspect that the murderer is among you."

Mrs. Bao smiled gently: "Really? This is really surprising, I mean, it's like a detective novel."

"You're right. This murder is so dramatic. The sky is an absolute secret room. No external factors should be considered. The murderer has nowhere to escape." Jian Jing said, "Now I can tell you that the deceased died of cyanide poisoning. So, I need to know what the deceased ate today."

She made a gesture and called the female model: "You go first. What did he eat in the morning?" Under

the watchful eyes of the crowd, the female model subconsciously shrank, but then she straightened her chest and said righteously: "I didn't eat anything. I drank a glass of water."

"Okay, then he went to the company." Jian Jing looked at the secretary, "What did he eat?"

The secretary thought carefully: "I bought him coffee and sandwiches according to Mr. Che's usual habit, but he didn't eat much. Then he asked me to buy cold medicine, uh, does water count?"

"Yes, anything else?"

The secretary racked his brains: "Mr. Che usually eats anti-smoking candies, I don't know if he has eaten them today."

Mr. Bao said: "He did, I saw it during the meeting."

"After the meeting, did you have lunch?"

The secretary nodded: "The company ordered lunch, and several CEOs ate together, but Mr. Che seemed to have a poor appetite and didn't eat much. I made him a cup of tea in the afternoon."

Jian Jing looked at Mr. Bao: "You were also in the company, do you remember what else he ate?"

Mr. Bao frowned and thought for a long time, shaking his head: "I didn't pay attention."

"So, what happened after we got to the airport?" Jian Jing turned to Mrs. Che.

Mrs. Che was indeed an all-round good wife, she remembered everything clearly: "Half a bowl of noodles and a glass of water, but he felt uncomfortable after eating and vomited it all. I told him that he had a stomach problem and that he needed to be hungry, so he didn't eat anything."

Jian Jing asked: "Does he like to drink milk?"

Mrs. Che nodded and explained: "When he was sick as a child, my mother-in-law liked to give him hot milk, so he likes to drink this every time he has stomach problems, although it is not good for the stomach."

"Is that so?" Jian Jing looked around, "Is there anyone else who can add to the list?"

No one answered.

Jian Jing looked at Mr. Meng: "Did you notice?"

Mr. Meng said: "I haven't spoken to him since we had a quarrel at the company."

"Speaking of this," Jian Jing seemed to have just remembered, "Since you had a quarrel with him, why did you go on vacation together?"

Mr. Meng sneered: "Why should I cancel my trip for him? He is the one who is playing tricks on me, not me who is doing it to him. Can't we just mind our own business when we get to the place?"

"Really? I thought you were going to expose some secret so that I could give him a slap in the face." Jian Jing smiled and didn't ask any more questions. Instead, she asked, "Second question, when did everyone leave their seats today?"

She called out names: "Let's start by seat, Mrs. Che?"

Mrs. Che: "I went to the bathroom once when I first got on the plane, then went to the kitchen to make milk, then accompanied the child to the toilet, and after lunch, I put on some makeup. A total of four times." Mr. Meng:

"I went to the toilet before dinner, that's all."

Jian Jing: "When?"

Mr. Meng: "I don't remember, anyway, they were preparing to distribute pre-meal."

Mr. Bao: "I accompanied the child to the toilet when the plane was just stable, and went there again after I woke up."

Jian Jing: "Do you remember the time?"

Mr. Bao : "Around eight o'clock. I remember the screen said that we still had to fly for more than 11 hours."

Mrs. Bao: "I went to the bathroom once while Mrs. Che was making milk. After lunch, I put on a facial mask for about fifteen minutes and washed it off in the bathroom."

The deceased's secretary: "I went to the bathroom before dinner."

Translator: "I went to the bathroom after the plane stabilized. After dinner, I took a walk in the back of the cabin."

The Bao family's nanny was very nervous: "I left several times. The child was running around and I kept following her. Oh, we went to the economy class and came back before dinner."

The flight attendant confirmed: "We saw her and the child."

Jian Jing nodded slowly and smiled: "Very good, thank you very much for your cooperation. I already know who the murderer is."
