"Yes, is it?"

Gao Cheng continued to pick up the water cup and brush his teeth and said, "in a word, whether it's the FBI or those organized by the organization, it's a trouble. During this period of time, when you go out, put on the hat and glasses I prepared for you, and then I'll take care of it..."

Xiao AI put aside the organization for the time being and asked, "is today's case still unsolved?"

"We should be able to solve it tomorrow, not too much trouble..."

Gao Cheng pauses, and the image of Dr. Kinson comes to mind.

It's still a bit of a problem. If that doctor is really the killer

"I see. You can refuel well tomorrow," Xiao AI went back to the kitchen with her hands on her back, "organize there... Don't hide from us, just take everything on yourself..."

"Oh."

Gao Cheng holds his toothbrush in his mouth.

Strange, I used to look ugly when I heard the news from the black clothes organization. How can I be so calm this time? I've been in a good mood since yesterday's Valentine's Day

Hurry to solve tomorrow's case and feel the situation of the FBI. After waiting for so long, we should take the initiative to attack. Otherwise, the black dress organization or belmaud, who pretends to be a new doctor, will find Xiao AI sooner or later.

That woman should know the real identity of Conan. If she sees Xiao AI, she will immediately think of Miyano Zhibao. Unlike protecting Conan secretly, that guy originally in Conan didn't know why he hated Miyano Zhibao to the bone

……

The next day, downstairs, office building of Aosong products company.

"This is the portrait made according to eyewitness testimony," Sato handed a drawing to Gao Cheng, "but it seems that this kind of dress is very popular recently, so it's impossible to lock the prisoner..."

Gao Cheng took the portrait.

A jazz hat, glasses, moustache, and a coat

Although the painting is better than Sato's, it's not easy to find prisoners by this kind of portrait. The reason why it's the same as the popular dress around is that prisoners deliberately disguise themselves.

"In addition," Sato continued, "before the crime, someone saw the man go to the urinal, and he was startled by the automatic outflow of water... That's all I know for the moment."

Gao Cheng returned the portrait to Sato and looked around: "maybe it's the first time I've entered the men's room. I haven't seen this kind of automatic urinal."

"Eh?"

"Officer Sato didn't know, did he?"

"You mean," Sato said in surprise, "the murderer is a woman?"

"It's just possible."

Gao Cheng looked around the office building: "is there a toilet for both men and women?"

Sato pointed to the office building: "next to the coffee shop is ah."

Kinson dental, Gao Cheng pushed the door and immediately rang the bell.

Different from yesterday's holiday, today there is no queue outside, only the sound of electric drill comes from the clinic.

"Mr. Chenghu," the female assistant noticed that Gao chenglian was busy, "the doctor is still busy inside..."

"I know."

Gao Cheng stood at the door and looked at it. With the bell ringing, he asked his female assistant, "did Dr. Nakasone go out from 2:00 to 3:00 yesterday afternoon?"

The female assistant seemed not in a good mood. She shook her head slightly and said, "I don't think so? I'm not sure... Isn't the doctor with you all the time? "

"That's right, but..." Gao Cheng took a look in the direction of the clinic and continued to ask, "what were you doing at that time?"

"Me?" The female assistant looked straight at Gao Cheng, "do I have to be suspected, too?"

"Don't worry, I'm not a policeman. I'm just asking," Gao Cheng said with a smile. "Can you tell me about yesterday?"

"I'm cleaning the patient's teeth..."

"Were there any other patients yesterday afternoon?"

"Well, it's Mr. Sasuke. I came here when I went to buy cold medicine for the doctor. I said that I must see the doctor's teeth..."

"Mr. Sasuke?" Gao Cheng asked, "what about Dr. Kinson at that time?"

"Isn't the doctor showing you teeth?" The assistant said strangely.

"Really? Did you see it with your own eyes? "

"No, no..."

"Do you remember Mr. Sasuke?" Gao Cheng covered his upper face and said, "could it be me?"

"What are you talking about?"

"At least remember the shape of your mouth?"

Gao Cheng opens his mouth and shows her teeth to her assistant.

"How's it going? Coincidentally, I was also cleaning my teeth yesterday... "

"I... I don't know," the assistant ran away with her head down. "I don't know anything..."

Gao Cheng leaned against the front desk and rubbed his eyebrows.

Speaking of this, the female assistant clearly understands that the so-called "Mr. Sasuke" does not exist at all.

Dr. Kinson is still busy in the diagnosis and treatment room. The sound of the electric drill is disturbing. It seems that it will not be over for a while.

When Gao Cheng walks into the office, his eyes sweep over the locked iron cabinet and fall on several documents.

Yamamura obviously took a dental fluoroscopy yesterday, and it was put together with his information

Looking at the information, except for a registration form and dental tablets, there was no content. It didn't write how to treat or what medicine had been prescribed. It just recorded the name and general information such as the clinic.

Like him, Yamamura was treated by Dr. Kinson in the bear room

"Lord Chenghu?" When Dr. Kinson came out of the clinic, he came across Gao Cheng in the office. "How did you come here ahead of time?"

"I think it's better to come earlier."

Gao Cheng looks at the female assistant who walks away with her head down, and turns to the bear and rabbit hanging ornaments outside the clinic. It's no different from yesterday

"Little bear and little rabbit are lovely, aren't they?" Kinson walked into the bear clinic with a smile, "come in, I'll show you the dental film."

"Well, do you really want to have an extraction?"

"Well..." Kinson put the X-ray dental film on the lamp. "The worm tooth has touched the nerve. It's better not to pull it out. The nerve can be cured only by cutting it off..."

"It's painful if you're nervous, isn't it? It's more painful than tooth extraction... "

"It doesn't matter. You can take anesthetics. Boys can't be afraid of pain."

"I hate injections," Gao Cheng said, sitting in the lift chair. "How long does it take if it's anesthetic?"

"Eh?" Kinson's fingers are slightly tight.

"It's painful because of the medicine, isn't it?" Gao Cheng laughs.

"Didn't I prescribe painkillers for you yesterday? You can take one when it hurts... "

"I see. Mr. Yamamura was treated like this yesterday..."

"Eh?"

Kinson's hands stopped.

Gao Cheng calmly said: "in fact, this piece of dental film is not mine. When I came to your office just now, I accidentally confused the two pieces of dental film. This is Mr. Yamamura's perspective dental film, but the doctor didn't notice it at all..."

"How, how?" Kinson suddenly looks at Gao Cheng, his face stiff.

"Why didn't you notice, doctor? Yesterday, my dental film was taken with the help of the doctor. Even though my worm tooth is almost the same as his, I know it's not so serious after seeing the dental film... "

Gao Cheng sits upright and looks directly at Kinson.

"Or doctor, when you filmed yesterday, you didn't take a good look at it. Instead, you were thinking about something else?"

"What are you talking about?" Kinson's eyelids jumped, grabbed his fingers and said with a strong smile, "what else can I think of..."

Gao Cheng crossed his fingers: "the murderer ambushed in the bathroom and waited for Mr. Yamamura, not by chance, but by knowing from the beginning that Mr. Yamamura would pass by at that time. Mr. Yamamura didn't go to the toilet, but because of the failure of anesthetic and severe toothache, he went to the bathroom outside the meeting room to take medicine..."

"I didn't kill anyone," Kinson frowned. "Didn't you say that, too? I was with you yesterday afternoon... "

"At that time, my eyes were covered. Even if I changed to another doctor and didn't speak, I didn't know who it was. Coincidentally, your female assistant was also cleaning the teeth of a patient called Sasuke..."

"You mean I used you to give me an alibi?"

"It's also possible..."

"But in this way," Kinson said with a smile, "miss setagawa is an accomplice, but she can't help me."

"Why?"

"Because she is the new lover of the mountain village."

"No wonder," Gao Cheng continued, "the reason for the breakup is that Mr. Yamamura fell in love with the beautiful young assistant beside the doctor... But what if Miss setagawa didn't know it at first? Just tell her that the patient must be treated by a doctor when she comes suddenly, let her pretend to be herself for a while, and then exchange the hanging decorations of little bear and little white rabbit without telling her. The effect is the same.... "

Kinson's face sank. "I said I didn't kill anyone. I was with you all afternoon yesterday."

"After the treatment yesterday afternoon, when you took off the mask here, there was a faint smell of mint, and after dinner last night..." Gao Cheng said in a deep voice, "Dr. Kinson must brush his teeth after eating. If you are here in the clinic in the afternoon, what can you eat during the treatment?"

Kinson got up with a dry smile: "you must have made a mistake. It should be the smell of the mask, because it was just disinfected..."

"Did the doctor order while waiting for the bathroom in the cafe?" Gao Cheng interrupted, "then I washed my mouth while changing clothes in the bathroom... In fact, when miss setagawa told me that there was a patient named Sasuke, I was thinking that although I was in the clinic at that time, there was no reason why I couldn't hear the bell at all..."

Kinson's face became more and more ugly: "what do you want to say?"

"In order not to be noticed, the doctor did something to lingdang when he went out, so miss setagawa thought you were treating me next door..."

"Enough!" Kinson turned to one side with a straight face: "I thought you were a good child... Please come back, I won't treat your teeth."“ Doctor... "Don't come again." Kinson picked up his tools and ignored Gao Cheng“ Don't think that if you've done several cases, you'll be very serious. If you don't have any evidence, you'll say something irrelevant... "" Dr. Kinson, "Gao Cheng stops at the door of the clinic and looks back at Kinson calmly." Mr. Yamamura is falling down in the bathroom, and his pills and bags are all taken away, Only a small pill was left in the corner... "Generally speaking, when taking medicine, he would only turn to look away, but Mr. Yamamura turned his whole body. It seemed that he was surprised to meet someone he knew. He even held the pill in his hand..." "so what?" Gao Cheng shook his head: "indeed, I haven't found any evidence yet, but the doctor's alibi has no effect... Dr. Kinson, as long as the police can investigate sooner or later, I just want to be tactful and have a good talk with the doctor..." Kinson opened his mouth, but his throat seemed to be stuck. He blinked and held back his tears: "Mr. Chenghu, Who the hell are you? "“ Didn't you say that I'm a detective? "Gao Cheng looked at Kinson who didn't look over his head." sorry, doctor... "Kinson wiped his eyes with his back." I'm the one who should say I'm sorry. "“ Mr. chenghujun, "Sato lifted the curtain, took his female assistant into the clinic, nodded to Gao Cheng and looked at Kinson," Mrs. Kinson, please come with us. "“ Can you wait, officer Sato? " Gao Cheng stopped Sato and walked to Kinson. "Does the doctor really not treat my teeth?" Kinson looked at the female assistant and Sato, and said with a smile, "sit down, I'll pull out all your teeth!"“ Ah? "“ It's a joke. "
