The man in Conan is the mastermind behind the scenes

"Can."

Mouri Kogoro nodded: "My left crutch has a wide range of motion, and the nurse is supporting my right side. I have been running very naturally, and the sound of the crutch hitting the ground is also very clear. I must have been using crutches before I finally tripped." "

Kudo Shinichi frowned slightly: "If you are running fast, is there any point in having the nurse support you?"

"She is also very fast and holds her very steadily." Mouri Kogoro said quickly.

"Then when you tripped, did you subconsciously open your left hand for a moment? At that time, the crutch was replaced by a knife. Then you realized that you should crutch and quickly tightened your grip on what you thought was the crutch, but it was actually the handle of the knife?"

"this……"

Mouri Kogoro raised his head and glanced at the people around him. He saw many doubts, and finally lowered his head: "I think this may be the case, but I can't be sure."

At this time, even he had a feeling that he was excusing himself from Kudo Shinichi.

Kudo Shinichi didn't care about this, but looked at the crutch in Mouri Kogoro's hand:

"The crutch fell next to you, Uncle Maori. According to you, everything happened in a very short moment, and neither Mr. Amuro nor Xiaolan saw the nurse. So, did she wear gloves?

If not, then she probably wouldn't have had time to wipe away the fingerprints left when she took the cane away. "

Mouri Kogoro's eyes lit up: "No! She didn't wear gloves! And I even touched her hand. It was very natural and soft, without the touch of glue!"

"..."

Mumu Shisan was speechless for a second: "Brother Maori, please let go first and let me take the crutch for testing to see if there are other people's fingerprints on it."

"And the knife too."

Kudo Shinichi reminded: "The nurse wanted to use the handle of the knife to replace the handle of the crutch without being noticed by Uncle Maori, so her hand must not be touched. And the knife was stained with blood, so the range she could hold was very narrow. She should It's close to the sword, even held between two fingers."

Mumu Shisan suddenly said: "Okay, let's test them together!"

The test takes time. Kudo Shinichi pondered for a few breaths, then turned to look at Toru Amuro:

"Can you find traces of your previous battles on Dr. Eto's body?"

Toru Amuro sighed: "Not only the traces caused by me, but also the traces caused by Miss Lan, most of them can be found and matched.

This is why I think substitution is unlikely. Could anyone have predicted in advance that Miss Lan and I would fight him at the same time and defeat Eto Victory like that? "

Kudo Shinichi was confused: "But didn't you also say that it was just most of the traces?"

"That person's moves are very flexible. The light was dim at the time, and there was no video for us to review. It's good to be able to confirm most of them." Toru Amuro shook his head, "And I've already searched around there, and I didn't find anyone hiding there. Great place.”

He paused for a moment: "A little below the ceiling, there are two shoe heel marks on the left wall. That is the only suspicious point, but there are no other focus points nearby. It is impossible for Eto Shengli to stick directly to them. "

"Could it be that his hand is on the wall at the other end?" Kudo Shinichi asked.

"Suppose there is really a person behind the scenes who beat Eto Seungri like that. No matter how stupid Eto Seungri is, he should have realized that something was wrong. How could he take the initiative to cooperate with him?" Toru Amuro asked, and continued:

"And almost the moment I hit Eto Seungri, the lights in the corridor turned on. There were only Mr. Mori and Mitsuo Shirai in front, and there was no one behind him. The ward doors on both sides were closed tightly, and there was no third person. Behind the scenes, How do people disappear?"

"Didn't you hear the door opening and closing?"

Kudo Shinichi frowned. He felt that this was very illogical and impossible.

"Someone was screaming at the time, and the sound couldn't be heard clearly, but there were patients in the two wards, and they were all awake at the time. I've already asked once, and they didn't see any strangers entering." Toru Amuro looked at Megure Ten three:

"The police can also ask again."

Megure Thirteen nodded and quickly sent someone to ask. His eyes looking at Toru Amuro became quite solemn:

"So, Mr. Amuro, you killed someone accidentally."

Toru Amuro smiled bitterly: "I don't want to either, but I can't help it. Things seem to be like this..."

"No!"

Kudo Shinichi looked at the window swinging in the wind and suddenly thought of something. He ran outside and went straight to the place where Amuro Toru said he found the shoe heel mark. Except for Mouri Kogoro who could not move without crutches, everyone else also They all followed quickly.

"Mr. Amuro, please hit the ceiling above the footprints, hit the very edge!"

The ceiling in the hospital corridor is quite large, about 1m x 1m, white with bright silver stripes. Kudo Shinichi looked at one of the ceilings with burning eyes.

Amuro Toru's heart moved and he immediately followed the instructions.

Wow——! ! !

That piece of ceiling moved the piece next to it, and it didn't actually fall. It just flipped downwards suddenly, and the ceiling behind it kept shaking.

Amidst the creaking sound, everyone saw what was painted on the back of the ceiling.

They are two patterns with simple lines.

a smiling face,

A crying face.

Chapter 162 The last link of abnormal love: love hormone!

Smiley face.

Crying face.

The expressions of these two swaying in the air were simply naked ridicule. Kudo Shinichi clasped his hands tightly, but his eyes shone with excitement.

This familiar feeling is Moriarty!

When he thought of this, he immediately thought of Qingzi.

Although Kudo Shinichi's suspicion of her has faded a lot after the auction in the underground casino, the sense of déjà vu is too strong now, and he immediately wondered if she was pretending to faint this time?

Could she be one of the three actors?

Kudo Shinichi immediately looked at Megure Jusan, but was worried that his guess was wrong and would have a bad impact on Kiyoko, so he leaned over and whispered:

"Collect a blood sample from Yuzuki Kiyoko to see if she was really anesthetized."

Megure Jusan nodded quickly and whispered to his subordinates, while Kudo Shinichi looked at Amuro Toru:

"Mr. Amuro, you are probably being used. Eto Shengli was placed on the ceiling at the time, and the person fighting with you was swapped with him in the few seconds when your vision fell into darkness.

You said that someone screamed at that time, but no sound was heard. Maybe that was arranged by the person behind the scenes."

Amuro Toru nodded heavily, acknowledging this conjecture, but still puzzled:

"Can that person disguise the injury to that extent? Is he a martial arts master? Is it possible that he calculated the location where we hit him?"

"Could he know you very well and is one of your acquaintances?" Kudo Shinichi asked.

"Unlikely."

Toru Amuro shook his head: "This is the first time Miss Lan and I have met. We have never had any intersection before, especially in martial arts. There are too many variables after the two of us join forces. Even if we get to know each other individually, it probably won't be possible."

In fact, he didn't say some details.

The man seemed to be struggling when fighting Xiaolan alone. After he went upstairs again, he kept aiming at him alone, and most of the injuries on his body were caused by Xiaolan.

However, he and that man have fought many times. He can fully anticipate these things in advance. That person is definitely a master in martial arts.

Kudo Shinichi doesn't know much about this aspect, so he can only nod and let it go.

The test results of all parties came out soon, first of all, the alarm clock in the 414 ward of the three buildings.

Mitsuo Shirai, Shengli Eto, and Kogoro Mori, all three have fingerprints on it.

This seems to directly prove that Kogoro Mori has adjusted the alarm clock. His mental state is even more worrying with the LSD evidence in the test report.

Secondly, there was no fingerprint of other people on the cane used by Maori Kogoro, which made his body shaky.

Fortunately.

Traces were detected near the blade of the murder weapon, not fingerprints, but some very shallow biological patterns, which were speculated to be the finger side marks left by the index and middle fingers pinching there.

This seems to explain something, but it is far from enough to say that Maori Kogoro is innocent.

The most important thing is, where did LSD come from?

Of course, putting this question aside, what Kudo Shinichi is most concerned about now is:

Kiyoko was actually anesthetized, and not just that?

Looking at the blood test report on Xuesong Kiyoko handed over by the doctor, Kudo Shinichi frowned at one of the data, pulled him aside and asked in a low voice:

"The oxytocin concentration is much higher than the average level, what does this mean?"

Oxytocin, a hormone and neurotransmitter produced by the hypothalamus and secreted by the posterior pituitary gland, also known as love hormone, plays an important role in promoting interpersonal trust, intimacy and social bonds.

Its level in the human body is generally quite stable, and intimate behaviors such as hugging, kissing and caressing can only stimulate it to a limited extent. Women's hormone levels will increase significantly when they give birth, breastfeed, and have sex.

And Kiyoko's current hormone level is...

Abnormal.

Very abnormal.

The doctor looked around and whispered: "No matter how good the emotional and psychological state of a normal person is, the oxytocin level will not be that high. I guess she took it exogenously."

"This..."

Kudo Shinichi frowned: "Why does she take this hormone? It's unnecessary."

"It may not be her own wish."

"Huh?!"

Kudo Shinichi's eyes were stern: "You mean, someone drugged her?"

The doctor shook his head quickly: "I didn't say that, but... well, anyway, this thing is a peptide hormone, which will be digested in the stomach and is generally taken in through nasal spray. Has she been exposed to that kind of thing recently?"

Spray?

Aromatherapy? !

Kudo Shinichi panicked, thinking it couldn't be that guy Shuiyue. He hurriedly told the doctor what happened in the hotel last night, but the doctor shook his head and asked: "Is it fireless aromatherapy?" Kudo Shinichi was stunned for two seconds and shook his head. The doctor shrugged: "How can biological hormones touch fire? But if you are worried, I can also draw a tube of your blood for testing." Kudo Shinichi quickly agreed, and a moment later, when he saw the test report that was slightly higher than the average but still within the normal range, he breathed a sigh of relief. The doctor's mouth curled up a smile of an experienced person: "You kid, you are dating someone recently, right? Your girlfriend is the Miss Kiyoko who you care about so much?" Kudo Shinichi blushed: "No way." But in a moment he became serious again, thinking about how Kiyoko could come across such a thing. It is unlikely that she actively uses any nasal spray, which means she has been in a certain environment, so she passively ingested it? They have been together for most of the past two days, and the only high-concentration environment that they could go to alone... is Kiyoko's home? !

When he thought of this possibility, Kudo Shinichi's eyes widened suddenly. Yes, the money used by Kiyoko to buy a new home was the insurance money of Xuesong Masato, and there was a shadow of a mastermind behind this money!

Regardless of whether that person was Ishida Mamoru, he wanted to get Kiyoko, so in the decoration of Kiyoko's home, he did not rule out the possibility of using means!

"How long can this kind of thing exist in the outside world?" Kudo Shinichi asked hurriedly.

"It depends on the storage conditions. At room temperature, it can be a few days at most. It can be refrigerated for several weeks, and frozen for several months." The doctor looked up and down at Kudo Shinichi: "I roughly understand your situation. Why don't you find a suspicious item and bring it to me for testing?"

Kudo Shinichi's eyes lit up: "Thank you, I will come tomorrow."

"No, it's today."

The doctor smiled and pointed to his watch: "It's one o'clock in the morning now."

Kudo Shinichi was slightly stunned and sighed in his heart. Yes, so much time has passed unknowingly, and there is still not much progress in the case.

After thanking the doctor, Kudo Shinichi returned to Building 404, where most of the people had already left. He looked around:

"Where are Mr. Amuro and Xiaolan?"

"The girl who called herself Maori Kogoro called and said she wanted to duel with him. They both went there." Chiba Kazunobu, who stayed behind, said.

"What?!"

Chapter 163 Anger is useless, the burning at the stake is over, and Xiaolan's level is far from enough!
