On the bus to Osaka City, Officer Otaki received a phone call.

On the phone, the police officer in charge of the investigation informed Officer Otaki of the results of the situation that Takato had asked the police to investigate again.

Hanging up the phone, Officer Otaki told the results of the investigation.

"The police went to inquire about the drivers who did not take the tunnel road on the day of the incident, and got a unanimous answer: when they drove to 1,000 meters away from the tunnel entrance that morning, they found a big sign in the middle of the road, which said 'construction ahead is not allowed to pass', so they had to go back and detour to other roads."

Hearing this answer, Gao Yuan showed a look of surprise.

"Sure enough, just like I thought."

And Hattori Heiji on the side also seemed to think of something from this clue, and after thinking for a while, he suddenly showed a surprised look, looking at Gao Yuan, a little incredulous.

"Hey, detective brother, no! If that's the case, how many people did it take to cause this car accident? ”

"The number of people is not a problem, but now considering that the nature of the whole incident has changed, it turns out that the police are looking for the wrong direction for the getaway truck."

Gao Yuan said.

"That's right. If the police initially thought that the truck was an escape, then in this case, the police generally believed that the driver of the escape was hiding the car and then finding someone to repair the crash marks. But now that it has been confirmed that this incident is a man-made conspiracy, then there is a high probability that this big truck was destroyed. ”

Heiji Hattori picked up the topic, but Officer Otaki, who was driving, was confused.

"Heiji, do you know what this incident is all about?"

Officer Otaki asked.

"Well, if nothing else."

Heiji Hattori said, "The problem now is to find the big truck that escaped. Officer Otaki, do you have a map here? ”

"There's only one traffic map of Osaka."

Officer Otaki said, taking out a map from the armrest of the car and handing it to Heiji Hattori in the back seat.

"Thanks."

Hattori Heiji results map, and look at it with Takato, who is sitting together.

"However, the police have been looking for so long and have not found the big truck, can you find clues based on the map alone?"

Officer Otaki wondered.

"Because the police investigation was in the wrong direction at the beginning. If it was a premeditated crime, then it is likely that the car was destroyed nearby. ”

Heiji Hattori said, finding the location of the tunnel where the incident took place on the map, and then followed the direction of the tunnel.

"They took great pains to make this accident look like an accident, and so many people were dispatched, and if they stayed on the main road for too long, they would be exposed to other passing vehicles."

Gao Yuan on the side said, changing the direction of the route from the main road to a small road, and in the direction of the path, there is a lake.

"You think they sank the car?"

Heiji Hattori said unexpectedly, "Although it is true that this can quickly dispose of the vehicle, the police will not be able to think of it anytime soon." But Shenhu is such a big move, although it is sparsely populated nearby, there will still be some private houses, and the people here will see this? ”

"Didn't you ask how many people were involved in this car accident? Do you think there are enough people in the houses around here? ”

Gao Yuan said.

"This ...... No way! ”

Heiji Hattori was a little incredulous about Takato's conclusion, but when he thought about it, he couldn't find a reason to refute it.

"Well, excuse me, how do you think this car accident is man-made?"

Officer Otaki still couldn't help but ask, after all, the current conversation between Takato and Hattori was based on this conclusion, but Officer Otaki couldn't think of how to artificially cause this car accident.

"There are two prerequisites for completing this case: first, you need to know when the car will pass through the tunnel; Second, when the car arrives at the tunnel entrance, it must be already dawn. ”

Hattori Heiji was the first to explain, "You have to know when the car will pass through the tunnel in order to prepare in the tunnel in advance; When the car arrives, it must be already dawn to ensure that the car does not need to turn on the lights before entering the tunnel. ”

"Why is that?"

After hearing this, Officer Otaki became even more puzzled.

"Remember what the director said. He did not see a vehicle at the entrance before the vehicle entered the tunnel. ”

Gao Yuan took over the conversation and explained.

Of course, he couldn't see a car at the entrance, because the entire tunnel intersection was blocked by a black curtain! Because the tunnel entrance was black before the vehicle entered the tunnel from outside the tunnel, the driver did not notice anything unusual. ”

"But there is a premise for this method, which is that the vehicle cannot turn on the lights. As soon as a light shines from outside the tunnel to the tunnel, the presence of the curtain is discovered. Therefore, it must have been dawn at the time of the crime, and the vehicle did not need to turn on the lights on the road! ”

Heiji Hattori further explained.

"But what if there were other vehicles passing by?"

Officer Otaki continued to question.

"So to achieve this method, someone must be responsible for checking whether the victim's car is driving over, and someone must be responsible for putting and collecting warning signs!"

Gao Yuan said, "On the day of the incident, there were several vehicles that often passed through the tunnel at that time, but because they were still a kilometer away from the tunnel entrance, they found a warning sign there, so they chose to take a detour. ”

"When you think about that, the whole thing is very simple."

Heiji Hattori said.

"Put a large truck inside the entrance of the tunnel and hang a large black curtain at the entrance of the tunnel. Because someone is responsible for releasing the warning signs, only the target vehicle will drive to the tunnel on this section of the road. And when the car drove at high speed, there was almost no suspicion, and it crashed straight into it!

"That's why there were no brakes on the car and why the director didn't see a big truck before the accident!"

Gao Yuan told the cause and effect of the incident.

"And afterwards, the perpetrator only needs to put away the warning sign and curtain, and leave together in a big truck!"

Heiji Hattori said.

"Thinking about it in another direction, if you want to complete this technique, you must know the itinerary of the car on that day, so that you can make so much planning in advance! Considering the matter of Mr. Nishikawa's will, the most suspicious person is only that person! ”

Gao Yuan agrees with this conclusion:

"And Mr. Nishikawa, who was still struggling with whether to find an illegitimate child, chose to carry out a plan to find an illegitimate child after the accident, and I'm afraid I guessed that his car accident was his current son, Nishikawa Hiroaki's ghost!"

"The challenge has been completed, and the settlement of Stage 3 has begun."

As soon as I said this, the settlement panel suddenly appeared!
