Cabin crew.

Gao Cheng watched as Nakagawa checked the body again.

This doctor is probably very confused, his subtle expression is very stiff, and he doesn't want to help with the investigation, but he can't pretend to be stupid in public, so he can only squeeze out a smile and pretend to be indifferent.

Nakagawa rolled up the sleeve of the corpse's arm and examined it expertly: "I can't find the needle, it's not long before I can see the red needle...... In this case, there is no possibility that he will kill him. ”

Gao Cheng's face remained unchanged, staring at Zhongchuan and said, "Is it okay to just check your arm?" Injections are possible elsewhere, right? Don't...... Is the doctor afraid of something? ”

"How, how is that possible?" Nakagawa smiled and stubbornly examined the corpse's legs and feet, "I didn't expect Detective Joto to know so much about this, haha." ”

"Understand a little bit." Gao Cheng smiled and stared carefully at Nakagawa's movements.

The pinhole was in the ankle of the corpse's right leg, which he had seen before, and it would just be a matter of trying Nakagawa again.

The facts are already obvious, this case requires medical knowledge, and ordinary people simply don't understand such a thing as myocardial infarction caused by high-dose potassium chloride injection.

There were at least 5,000 passengers on the train, but there was only one doctor, Nakagawa, and I didn't know whether to call this guy unlucky or something.

Anyway, the guy was suspicious from the start......

"Anyway, let's contact the police at the next station," Gao Cheng turned to the conductor, "It's a homicide." ”

Nakagawa's face changed uncertainly, and he stood silently, not even paying attention to Gao Cheng walking out of the flight attendant room.

Gao Cheng looked at Zhongchuan and whispered to a flight attendant: "Please help me look at Dr. Zhongchuan, and let people tell me if there is anything abnormal." ”

The flight attendant didn't quite understand and nodded confusedly.

Seeing this, Gao Cheng was a little helpless, it would be nice if Officer Mudu was there, but unfortunately he was on the train now, so he could only take the lead, and the key was not to let Nakagawa leave.

"Can you take me to the seat where the body was found?" Gao Cheng continued.

"I'll take you." Mao Sui, a flight attendant who was looking for a doctor before, recommended himself.

Zhongchuan came back to his senses, watched Gao Cheng leave with the flight attendant, subconsciously touched the pocket of his coat, took out a pair of glasses behind everyone's back, and cold sweat flowed on his forehead.

Not only glasses, but also cigarettes and mobile phones are all in both pockets......

"Doctor?" The conductor suddenly said to Nakagawa, "Please don't publicize this matter, otherwise the other guests will panic." ”

"Oh, I know." Nakagawa hurriedly put away his belongings, turned around and squeezed out a smile at the conductor, and walked out of the attendant's room with a heavy heart.

In the No. 8 car, the attendant took Gao Cheng straight to the front row, pointed to the window seat on the right and said, "This is it, No. 1D seat." ”

Gao Cheng leaned over and looked at it, "You haven't touched anything, have you?" ”

The flight attendant whispered: "Except for taking the luggage and the ...... Corpse ......"

Gao Cheng frowned and looked at the deceased's seat, then looked at the back.

Although it was also a special class, there were more people in car 8 than car 7, and there were exactly two people behind the deceased's seat, a woman and a man with a scar, but they were all sleeping.

Nakagawa not only injected the victim's ankle, but also took the victim's coat away, I don't know if anyone has seen it, if so, the matter is much simpler.

Seeing that Zhongchuan was still staying in the cabin and did not come over, Gao Cheng was thoughtful, and a smile appeared on the corner of his mouth.

It's still possible......

"Can I trouble you?" Gao Cheng turned to the flight attendant and said, "Ask the passengers in this carriage if anyone has seen a suspicious person approaching here." ”

The flight attendant looked at the scar man sleeping in the second row in embarrassment, but he couldn't refuse Gao Cheng, and turned to ask the passengers who were not sleeping.

Gao Cheng didn't care about this when he saw this, and sat directly in the deceased's place, and assumed that he was the murderer.

In order not to attract attention, they presumably pretend to be passengers sitting next to the deceased......

His gaze casually swept over the seat next to him in the aisle.

Although the back of the chair was not lowered, the footrest was down, apparently someone had sat on it, and there was a small white orange skin band on the table stand.

Someone sat next to it and ate oranges......

Gao Cheng carefully wrapped the fruit band with a handkerchief, thought about it, and quickly crossed the aisle back to the flight attendant's room.

Zhongchuan hadn't left yet, but stayed outside peacefully, and a smile appeared on Gao Cheng's stiff face after seeing him: "How is it?" Did you find anything? ”

"I'm still asking the passengers to see if anyone has seen the murderer," Gao Cheng said casually, "Does Dr. Nakagawa want to help?" ”

"Ah, no, no," Nakagawa hurriedly waved his hand, "I'd better stay here and help." ”

Gao Cheng said with a smile: "I've already troubled a lot of doctors, so let's leave it to us next, you can go back and rest first." ”

"Oh, good."

Nakagawa pulled the coat he was wearing a little unnaturally, entered the No. 8 car with stiff steps, and saw that the flight attendant was questioning the passengers, and immediately shrunk and passed quickly.

Gao Cheng looked at Nakagawa's return to the No. 7 car, paused, knocked on the door and walked into the attendant's room.

The conductor inside was still guarding the corpse and luggage with a distressed face, a little restless, and was relieved to see Gao Cheng come in.

Gao Cheng sniffed the fingers of the corpse's hands, but did not smell the smell of oranges, noticed the strange face of the train conductor, and said, "You are afraid of the dead?" ”

"No, no." The conductor shook his head and denied it.

"I'm a little scared," Gao Cheng said as he walked out of the flight attendant's room, "I'm sorry to continue to guard." ”

"The ......"

Seeing that he was left with another one, the conductor had a hard time.

Gao Cheng walked to the dining car with a flight attendant, and the beautiful waiters before were still at the counter, and when they saw Gao Cheng, their whole faces collapsed, and they felt uncomfortable.

"It's this weirdo again......"

"Ugh." Gao Cheng didn't pay attention to the waiter's strange appearance, but just recalled the previous meeting with Nakagawa.

At that time, Nakagawa did buy oranges, and the killing should have happened after that, and the second meeting was in car 7, and at that time Nakagawa had an extra coat in his hand.

Judging from the circumstances of this case, the technique is not very skillful.

Nakagawa should have met with the victim, and gave the victim sleeping pills in advance, waited until the victim fell asleep, pretended to be a companion, took the coat, and returned to car No. 7 as if nothing had happened.

Thinking of this, Gao Cheng turned around and walked towards the B dining car.

Seeing this, the beautiful waitress asked the flight attendant in confusion, "What's wrong with that passenger?" ”

"What's wrong? Don't talk nonsense. The flight attendant hurriedly followed Gao Cheng, for fear of missing something.

There are still a few passengers drinking coffee in the B dining car, and there are also people who come to eat, Gao Cheng glanced at it casually, and the attendant immediately asked in a low voice: "Detective Chenghu, is there any problem?" ”

"I'm wondering if the deceased had dinner with anyone, can you bring a waiter to meet the deceased?"

Gao Cheng knew that the evidence was the coat on Nakagawa's body, and the only problem was to prove that Nakagawa was a prisoner, to prove that Nakagawa knew the deceased and had sat in the seat next to the deceased.

After a while, a waiter followed Gao Cheng back to the flight attendant's room.

When the conductor opened the door, he was still a little trembling, his face was pale, and he was stunned: "What's wrong?" ”

"It's okay," the conductor said, leaning on the table, "it's just that the window was accidentally blown open by the cold wind, and it was a little cold." ”

"Oh?"
