Ke Xue: Shinichi and I are childhood friends

Kiriu looked at the sea from a distance and asked faintly, "Do you know the special attack team?"

"Special attack team?" Yuya frowned. The words of the wartime special attack team, "Does it mean the kind of troops that risk their lives to attack and die together with the enemy?"

Kiriu nodded and said, "Most people know about the special attack that drives fighter jets to hit enemy ships, right? But it's different here, it's not fighter jets but torpedoes."

"Torpedoes?" Yuya narrowed his eyes.

"That's right, people sit on torpedoes and attack ships from underwater."

"And the base here is the training base for 'Human Torpedo-Kaiten'. Countless young people sit on torpedoes and set off from here to attack the enemy's fleet..."

"My son is among them..."

"..." Yuya was silent for a while, then said, "So you live alone on this island, to accompany your son?"

Kiriu sighed.

At this time, the sound that continued to come from the sea suddenly changed, and the cry of the Siren was a little different.

"It's changed again..." Yuya glanced at the sea.

Kirio forced a smile and said, "I'm going to catch some fish for dinner." Then he walked around Yuya and walked into the hotel.

Yuya looked at Kirio's back thoughtfully, walked to the railing at the bridge head and looked down.

"She knows when to fish again. It turns out that whether or not you can catch fish has a lot to do with the cry of the siren." Yuya analyzed.

Miyano Shiho thought for a moment and said, "Could it be related to the ebb and flow of the sea? Didn't you say that the cry of the sirens might be caused by the change in the air caused by the ebb and flow of the sea?"

Yuya's eyes lit up: "Is that so. When the tide is high, the sea flows to the land, and the fish are also brought along, so we can catch fish; when the tide is low, the fish are taken away by the sea, so we can't catch them."

Yuya kissed Miyano Shiho on the face and grinned: "You are so smart!"

Miyano Shiho said lightly: "Isn't this common sense? You just didn't pay attention and didn't think of it." While speaking, he raised his hand and wiped the saliva on his face with the back of his hand.

Yuya's face fell: "Do you dislike my saliva?"

Miyano Shiho paused and said calmly: "No, spread it evenly."

Yuya was stunned, and then burst into laughter.

···

In the living room, Yuya sat on the sofa, holding his mobile phone to check information.

Shiratori Renzaburo pushed the door and walked in.

"Inspector Shiratori, did you find anything?" Yuya looked up and asked.

Shiratori Renzaburo shook his head: "I checked a part of the area roughly, but I didn't find any signs of human life."

He poured a glass of water and sat next to Yuya. He looked at his mobile phone screen, which was full of dense text, and couldn't help asking: "What are you looking at?"

Yuya looked at the screen and said: "I'm checking the time of high and low tide in this sea area. It's almost the same as I expected."

Shiratori Renzaburo drinking water After a pause, he asked in confusion: "What does it mean?"

Yuye pointed to a text on the screen and said: "The tides here are very punctual, with a difference of less than half a minute, and 10 o'clock last night was exactly the time of low tide."

Shiratori Renzaburo was puzzled: "What does this mean?"

Yuye's mouth curled up slightly: "Of course, this means that there was probably no one on the boat we saw last night!

If my guess is correct, the murderer should also be someone who knows the time of high and low tide, and used this to set up a timed mechanism, and used the low tide of the sea to kill Miss Hanye at 10 o'clock!

In this case, it also explains why the letter requires us to strictly Strictly abide by the time. If we go to the agency too early, we will fail and may kill others by mistake. If we go too late, Miss Han Ye will have been killed and we cannot guarantee that everyone is present. "

Shiratori Renzaburo's eyes widened slightly: "According to what you said..."

"That's right," Youya nodded, "Plus, Inspector Shiratori, you didn't find any traces of other people's lives, I suspect the murderer is among us!"

Shiratori Renzaburo asked hurriedly: "Do you have any suspects?"

Youya was silent for a while and said: "Except for the three of us, everyone else could be the murderer. But now there is no evidence, I dare not make a rash conclusion."

In fact, Youya already has a suspect in his mind, that is Fengtian Xiajian.

When everyone gathered yesterday, the female tour guide Fengtian Xiajian seemed to have had some grudges with the five people, and two of the five people had already died.

According to the Conan animation he has watched, such people are often the most suspicious.

But as he said, there is no evidence now, so he didn't sayAfter finding out his suspect, he could only continue the investigation.

"Let's go to the scene where Miss Han Ye was killed and take a look." Youya said.

Shiratori Renzaburo nodded, and the two of them came to the salon together.

First, they checked the room, and the result was the same as last night, and there was nothing found.

Youya sat on the chair where Han Ye Meihuo was killed. He compared Han Ye Meihuo's height in his mind, and then adjusted his sitting posture so that his head was about the same height as Han Ye Meihuo at that time, and then looked out the window.

This time, he really found something.

Taking Han Ye Meihuo's eyebrows as the starting point, the hole in the window glass as the middle point, and the end point, just happened to be on the railing outside.

If Han Ye Meihuo was really killed by someone with a timer mechanism, there is a high probability that there will be some traces left there.

Youya called Shiratori Renzaburo, and the two came to the railing.

Youya carefully searched on the wooden railing, and sure enough, he found a suspicious trace on it.

"Inspector Shiratori, look here." Yuya touched the railing, and there was a vertical mark on it, which looked like it had been rubbed by something hard.

"This mark is still very new, it should have been left recently." Yuya said.

Shiratori Renzaburo also looked at the mark, with a serious expression on his face, took out his mobile phone to take a picture of the mark, and then said: "It seems to be basically consistent with your guess."

Yuya nodded slightly, looking under the wooden railing, the sea water had receded and exposed a large area of ​​pebbles on the ground.

"When we came, the sea water should have been high tide, and it had reached a high tide before 10 o'clock in the evening. The sea water had already spread below here."

"And according to the information I investigated, 10 o'clock is when the sea water recedes."

Shiratori Renzaburo recalled the situation last night and nodded affirmatively.

He speculated: "So, the murderer should have parked the boat below, then set up the mechanism, and finally used the time when the sea water began to recede at 10 o'clock, and the boat moved away with the tide to activate the mechanism and kill Miss Han Ye."

Yuye nodded: "If possible, we'd better find the boat, there may be more information on it. Inspector Shiratori, didn't you see the boat just now?"

Shiratori Renzaburo shook his head.

Yuye thought for a while and said: "Now it's high tide, maybe the boat will be pushed to the shore by the sea, let's go to the shore to look for it."

"Okay."
