"This ratio...... It's the key, right?" said Miwako Sato, looking at Ayumi's cuffs.

"It's indeed the key," Mizuma Yue nodded, "Besides, I know where the little fat man sat just now." "The pattern on Yuantai's ass is not the same as Ayumi's, there are some more slender lines, and it is thanks to these lines that the prototype of the pattern is found.

"Where?" the crowd asked excitedly.

"Oh, it's Miwako's car, did the little fat man sit on the hood just now?"

Everyone looked back and saw that it was true, wasn't that pattern the logo of Miwako Sato's car!

"Really, don't just sit around, if you break the hood, I'll arrest you. Miwako Sato feigned anger and scared Motota and said.

"Cut, that's stingy. Yuan Tai said, covering her buttocks.

"Could it be that the murderer is actually Officer Sato?" Suddenly Mitsuhiko's brain circuit convulsed, and he looked at Miwako Sato and Mizuma Moon in horror, and took two steps back, as if he was afraid that the two of them would kill people.

"Are you joking? It's just the same car that the murderer and Miwako drove!" Mizuma said as she looked speechlessly at Mitsuhiko who seemed to be on the upper body of Motota or the upper body of a pig's head.

"Mitsuhiko, did you eat eel rice today?" Avia couldn't help but complain.

"Hee-hee...... I'm just telling a joke, just telling a joke......" Mitsuhiko defended.

"Then let's send someone from the Metropolitan Police Department to find all the Efini owners in the vicinity. "It's finally a bit of a breakthrough, and Mizuma Moon is in a pretty good mood.

"Wouldn't that be a lot of cars?" When Miwako Sato called the Metropolitan Police Department, Ayumi took the initiative to ask, of course, not Mizumatsuki.

"Although Mazda is a common model, the Efini with this logo has been out of production for a long time, so there are not too many cars on the market, and the prisoner can't get the master key, so the search range can be smaller. Conan explained to Ayumi.

"Can't get the master key?" Ayumi still didn't understand.

"Because his key is stained with blood, it's impossible to give the master key to the police. Conan said.

"Master key, secondary key?" the little ghosts looked confused.

"There are two main and secondary keys for a car key," Conan explained, "and the teeth of the primary and secondary keys are different on 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 doors, not the trunk." Conan continued to explain: "Although the black mark on Ayumi's cuffs can't 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 that time, and if you take it out, it will be exposed as soon as you check it!"

"Alright. Let's send you home first, and we'll go back to the case. Mizuma interrupted, he was also listening to Conan's inference just now, but he felt that his idea was too idealistic.

Even if the bloodstained things are cleaned in large quantities, they will be obvious under the luminol reaction, but it doesn't mean that all prisoners also know this, in case the prisoner is stupid to wash and hand it over to the police, and as a result, because he just thinks that the prisoner can't take out the master key, he jumps over, then it's not that the prisoner is stupid, but the police are stupid.

According to the most undesirable situation, finding all the people who drove the efini car nearby is just to narrow down the scope of the investigation, since the prisoner has the car key in his hand, it should be a car escape, of course, it is not ruled out that the prisoner deliberately misled the investigation and found that he left a false clue, but this clue is too obscure, and it is unlikely to be fake.

"I'm going too! I've heard the prisoner's voice, and I'll recognize it if I hear it again. Hearing that Mizuma Moon was going to send her home, Ayumi said dissatisfied.

"yes, Ayumi can help too!" The other three were also there to share the enemy's hatred.

Mizuma looked at them condescendingly, and the joints of her hands moved with a rattling sound: "What did you just say?"

"Nothing ......" four wobbly rattles.

"Mizuma......" Miwako Sato reminded: "Don't always look like a violent problem-solver, it's easy to be reported. ”

"And they seem to have a point, if they can't catch that serial murderer this time......" Miwako Sato persuaded again.

Mizuma was silent...... If it were other types of cases, he would definitely not say a word and chase the unrelated people as far away as possible, but this time the murderer is a serial murderer, if he can't find out this time, let him hide in the vast sea of people from now on is small, and it is big to continue to commit crimes and kill!

"I'm against it. At this time, Gray Yuan Wai suddenly said: "If you let Ayumi go to meet the murderer, what if the murderer is not found this time, causing Ayumi to be retaliated against?"

That makes sense...... However, Mizuma Moon still felt that Gray Yuan's personality was a little awkward, as if she liked to sing the opposite.

"Didn't the prisoner just appear at the scene, even if Ayumi didn't go, the prisoner would have already remembered it!" Conan retorted.

"What if you don't remember it? If you go because of Ayumi and end up being remembered by the prisoner, doesn't that increase the danger?"

"You can't lose because of the danger! Conan exclaimed.

Ashbara froze, and Conan stared into her eyes.

Can't you lose because of the danger?? Gray Plains turned his head away and stopped arguing with Conan.

Everyone looked at Shui Jianyue, after all, no matter how passionate they were discussing here, it turned out that Shuijian Yue would be out of trouble if he didn't take them there.

Mizuma turned around and walked towards the police car, without saying a word, as if she hadn't heard the previous argument and upheld the verdict.

Just when the enthusiasm of the little ghosts was about to be completely dispelled, Mizumatsuki opened the car door and said to herself: "I remember that there is a one-way glass official car for stalking in the Metropolitan Police Department, and I will lock you in when the time comes." “

"Hooray!" the imps cheered, for Mizuma's words sounded like a disguised agreement.

"Alas......" Mizumatsuki sat in the cab, helplessly looking at the little ghosts who were jumping and jumping outside and delaying in getting into the car, and really didn't want to admit it, but was moved by Conan's words.

On the way back, because there was still a step in the car that had to walk with Conan Gray Plains, Conan lost the opportunity to talk to Mizuma again.

Because the area of the first search was not very large, when I returned to the Metropolitan Police Department, I had already found three owners who drove different models of KFINI cars, and Mizuma sent Takagi to do a simple inquiry first, and he took the little ghosts to borrow the official car with one-way glass first.

Because it was originally used for stalking, the space of this car was very spacious, so that the police officers could move around in the car, so all six imps were crammed into the back row, and it was not too crowded.

Parking the car facing the wall and butt outward to the outside parking lot, Mizuma met the three eligible car owners.
