Although Mori Kogoro was invited by Aso to write a letter, he pretended not to know anything about the letter. Once he admits to writing the letter, then he becomes a murderer, and as long as he doesn't admit it himself, then no one can do anything about him.

The Twilight Police Department knew this, so he didn't want to continue to stalk about the letter, so he directly introduced the topic of murder, and asked Cheng Ji with an unkind face: "There are still many doubts about your father's death, did you find out the truth and found that your father's death was related to Mr. Kawashima, so you killed him?" ”

This is the truth of the matter, but it is obviously impossible to admit it.

His face showed the anger of being framed, "It is unreasonable that the police can casually identify others as murderers without evidence?" Twilight was stunned by him for a while, there was no evidence or anything.

At this time, Lin Si spoke, "I want to ask, how long does it take to get from the clinic to Mr. Kawashima's house?" This sentence is not for the police, but for local residents. Conan had a flash of inspiration, and he had already guessed what Lin Si was thinking.

However, I heard the old local inspector say: "It takes about 15 minutes from the clinic to Mr. Kawashima's house. "The old inspector patrols the island every day, so he knows the local situation better than anyone else.

"So how long does it take to get from Mr. Kawashima's house to the riverside where the body was found?" Lin Si asked again. At this moment, even Mori Kogoro and the Twilight Police Department realized what Lin Hei was thinking.

The old inspector thought for a moment and replied, "It will take about 10 minutes." ”

"10 minutes and 15 minutes?" Lin Si muttered to himself in a low voice, then raised his head and scanned everyone, and said, "If this is the case, then Asai Chengshi should be unlikely to commit a crime, and it is too late at all." ”

"What do you mean?" The Twilight Police Department was slightly puzzled.

So Lin Si went through the timeline of what happened last night.

22:00 Mr. Kawashima posted a video of him drinking with Mr. Nishimoto in the group;

22:20 Narumi Asai came to the activity center to find the lost bracelet and stayed with everyone until he found Mr. Kawashima's body.

"If Asai Narumi is the murderer, then he can only kill Mr. Kawashima between 22:00 and 22:20, because Mr. Kawashima is still alive at 22:00." "It takes 15 minutes from the clinic to Mr. Kawashima's house, 10 minutes from Mr. Kawashima's house to the river, and 5 minutes from the river to the activity center. The journey takes 30 minutes. ”

"That's right...... Xiaolan felt very reasonable after hearing this, "so Mr. Asai won't have time to commit the crime at all." ”

When everyone thought that Lin Hei was right, Conan put forward another opinion without believing it, "Maybe Mr. Asai has been hiding near Mr. Kawashima's house for a long time, so the 15 minutes from the clinic to his house can be omitted." ”

Xiaolan was slightly surprised. Can it still be like this? How did Conan come up with this?

However, when Conan made this view, the old inspector couldn't help but shake his head and speak, "That's impossible, because I was patrolling the road at nearly 22:00 last night, and Dr. Asai was still near the clinic." I'll do the math...... Well, the exact time should be around 21:55. ”

Conan was stunned, and there was such a thing?

Cheng Shi explained: "I went out to go to the activity center to find a bracelet. ”

In fact, it is no coincidence that the inspector saw Chengshi, Lin Si will not bet the plan on probability, he discussed with Chengshi and determined that the old inspector would pass by the clinic at this time. As for why...... Conan has thrown the question out.

"Why do you remember the time so clearly?" Conan looked suspicious.

The old inspector replied proudly: "Because I patrol the island on time from 19:00 every night, and there is a regular time to patrol everywhere at what time." Last night, due to the death of the village chief Kameyama, the patrol did not start until 21:00, but as long as the usual patrol time to the clinic was postponed by 2 hours, it was almost enough. ”

That's right, the old inspector patrols on time every day, and this rule has been mastered by Asai Narumi. The old patrol proved that Cheng Shi could not commit the crime.

Even if Sungmi set off immediately after 21:55, arrived at Mr. Kawashima's house at 22:10, and then transported the body to the river, it was already 22:20, and it would be too late to go to the activity center. Even if he drove Mr. Kawashima's car when he was transporting the body, even if 10 minutes was shortened to 1 or 2 minutes, it would not be enough time to go to the activity center because the car stopped by the river in the middle of the way.

The main thing is that the killing process also takes time, and this time has not been calculated.

"Does he have his own transportation?" The Twilight Police Department asked.

Cheng Shi said that he did not have a car, and the old inspector could also testify. In other places, a prisoner can lie that he doesn't have a car, but it doesn't work here, because this is an island, and cars can only be brought in by boat, and if there are cars, the inhabitants of the island can't be unaware.

He did have a bicycle, but it was dusty in the clinic's warehouse, and apparently no one had ridden it for a long time. At this point, the suspicion of Asai Narumi has been completely cleared.

……

Just when the police had nothing to do, Xiaolan suddenly pointed to the distance and shouted, "Huh? Look, why is there smoke over there? Everyone looked in the direction Xiaolan pointed, and sure enough, black smoke rose in the distance, soaring into the sky.

It's just that there are too many trees on the island, so everyone can't tell what is burning for a while.

"What's that place over there?" Kogoro asks the old inspector a question.

The old inspector looked over there and shouted, "That's the direction of the village chief's house!" Worst! Could it be that there is a fire over there? ”

The image of the short and chubby village chief of Kuroiwa came to everyone's minds, and the Dusk Police Department shouted, "Let's go over and have a look!" ”

So the group left the clinic and ran towards the place where the black smoke had risen.

Sure enough, the black smoke came from the village chief's house, and the village chief's house was on fire, and the smoke was billowing and the flames were rising to the sky. When Lin Si and his party arrived, there were already many nearby residents carrying buckets to put out the fire.

"What the hell is going on?" The old inspector grabbed a resident and asked.

"I don't know!" The resident replied with a bucket: "The fire was already burning fiercely when we found it, and the fire truck had not yet arrived, so now we have to fight the fire ourselves." With that, the resident hurried to splash the water again.

Everyone was looking at the burning house, but Lin Si suddenly asked, "Did you hear any strange sounds?" ”

"Strange sounds?" The crowd pricked up their ears, but heard only the noise of the inhabitants.

Conan's ears were obviously much better than everyone else's, he closed his eyes and listened carefully for a while, then suddenly opened his eyes and said, "I heard it, it's from here!" Conan turned and ran towards the flowerbed, where he found a mobile phone.

Mobile phone again? And the same music is playing? Everyone remembered Mr. Kawashima's case last night.

"This ...... What is this playing? It's a little different from yesterday's song! "Kogoro doesn't know much about music.

Conan and Lin Si said almost in unison, "Beethoven's Moonlight, second movement." ”

First the first movement, then the second movement, and the Dusk Police Department was frightened, "Is this ...... Serial homicides? ”
