"This ratio... is it a key?" Sato Mikako said as she looked at Arimino's cuffs.

"It's indeed the key," Mizumatsu nodded: "In addition, I know where the little fat man was sitting just now." The patterns on Yuan Tai's butt were different from those painted by Arimi. There were some slender lines, and it was thanks to these lines that I found the prototype of the pattern.

"Where?" everyone asked excitedly.

"Here, it's Miwako's car. Did the little fat man sit on the hood just now?"

Everyone looked back and found it was true. Isn’t that pattern the car logo of Mikako Sato?

"Really, don't sit around casually. If the hood is broken, I will catch you." Mikako Sato pretended to be angry and scared Yuanta.

"Tsk, so stingy." Yuan Tai said, covering her butt.

"Is the murderer actually Officer Sato?" Suddenly, Mitsuhiko was in a state of terror, looking at Sato Mikako and Mizumatsu in horror, and took two steps back, as if afraid that the two of them would kill and silence them.

"Are you telling a joke? It's just the same car driven by the murderer and Mikako!" Mizumatsu said speechlessly as if he was on the upper body of Murata or on the upper body of a pig.

"Miyoshi, are you eating eel rice today?" Aviya couldn't help but complain.

"Hehe... I'll just tell a joke, just tell a joke..." Mitsuhiko, who reacted, defended.

"Then let's send someone from the Police Department to find all the owners of the Efini cars in the nearby area." Finally, I had a breakthrough, and Mizumatsu was in a pretty good mood.

"Wouldn't you find a lot of cars?" As Ayumi asked when Sato Mikako called the Metropolitan Police Department, of course, he was not Mizumaki.

"Although Mazda is a common model, the efini with this logo has been discontinued for a long time, so there will not be too many cars on the market, and the prisoner cannot take out the main key, so the search range can be smaller," Conan explained to Ayumi.

"Can't take out the main key? Why?" Ayumi still doesn't understand.

"Because his key is covered with blood, it is impossible to hand over the main key to the police." Conan said.

"Main key, secondary key?" The little ghosts looked confused.

"The car key is divided into the main key and the secondary key," Conan explained: "And the teeth of the main and secondary keys are different at the head of the key, because the main key can open the trunk, while the secondary key can only start the car and open the door, and cannot open the trunk." Conan continued to explain: "Although the black mark on Ayumi's cuffs cannot distinguish the specific tooth shape, it can be seen that it should be the main key, so the murderer's main key was stained with a lot of blood at the time, and if it was taken out, it would be exposed as soon as it was checked!"

"Okay. I'll send you home first, we'll have to go back to handle the case." Mizumatsu interrupted. He was listening to Conan's inference just now, but he thought his ideas were too ideal.

Even if the blood-stained thing is washed in large quantities, it will be obvious under Lumino's reaction. However, it does not mean that all prisoners know this. If the prisoner is stupid and washes it and hand it over to the police, the result is that the prisoner just can't take out the main key and jumps over. That is not the prisoner is stupid or the police are stupid.

Considering the most unsatisfactory situation, we found all the people driving Efini nearby to narrow the scope of investigation. Since the prisoner was holding the car keys in his hand, he should have been driving and escaping. Of course, it is not ruled out that the prisoner deliberately misleads the investigation and finds false clues left. However, this clue is too obscure and there is little possibility of fraud.

"I want to go too! I have heard the prisoner's voice, and I will definitely recognize the words I hear again." When Ayumi heard Mizumatsu want to send her home, he said dissatisfiedly.

"That's right, Arimi can help too!" The other three were also there to share the same hatred of the enemy.

Mizumi Moon looked at them condescendingly, and clattered with his hands moving: "What did you say just now?"

"Nothing..." Four shaking rattles.

"Mimama..." Sato Mikako reminded: "Don't always look like she solves problems violently, she is easily reported."

"And what they said seems to make sense. If they can't catch the serial murderer this time..." Sato Mikako advised again.

Mizumatsu was silent... If there were other types of cases, he would definitely chase the irrelevant people away, the better. However, the murderer this time was a serial murderer. If he couldn't find him out this time, it would be small to hide in the vast crowd from now on. It would be big to continue committing crimes and killing people!

"I object." At this time, Ai Haibara suddenly said: "If Ai Mi gives in to meet the murderer, what if the murderer is not found this time and Ai Mi is retaliated against?"

What he said makes sense... But Mizumaki still feels that Ai Haibara's personality is a bit awkward, as if he likes to sing the opposite tune.

"Didn't the prisoner appear at the scene just now? Even if Arimi doesn't go, she has been remembered by the prisoner!" Conan retorted.

"What if I don't remember it? If I go there instead and the prisoner remembers it? Isn't that increasing the risk?" Haibara Ai retorted.

"It's because of danger that you can't lose! You must win with all your might." Conan said loudly.

Haibara Ai was stunned, Conan stared in her eyes.

Can't you lose because of danger? Haibara Ai turned his head and stopped debating with Conan.

Everyone looked at Mizumatsu. After all, they were so passionate about discussing here that Mizumatsu would be helpless if they didn't take them there.

Mizumatsu turned around and walked towards the police car without saying a word, as if he had not heard the previous arguments upholding the original verdict.

Just when the little ghosts' enthusiasm was about to be completely dispersed, Mizumatsu opened the car door and said to himself: "I remember there is a one-way glass official car used for stalking in the police station. You can be locked in at that time."

"Long live!" The little ghosts cheered, because Mizumatsu said it sounded like a disguised agreement.

"Oh..." Mizumatsu was sitting in the cab, looking helplessly at the little heads who were jumping and jumping outside and were not getting on the car for a long time. I really didn't want to admit it, but I was actually moved by Conan's words.

On the way back, because there was a Akimi in the car who insisted on walking with Conan Haibara Ai, Conan lost the opportunity to talk to Mizumama again.

Because the area for the first search was not very large, when I returned to the police station, I had already found three owners who drove different models of kfini cars. Mizumatsu sent Takagi to do a simple inquiry first, and took the little devils to borrow the official car with one-way glass.

Because it was originally used for stalking, the space of this car was very spacious so that the police could move around in the car. Therefore, all six little ghosts were stuffed into the back row, which was not too crowded.
